An updated meta-analysis of 11 studies from universities, think tanks, and non-governmental organizations converge on the feasibility of achieving 80 percent clean electricity by 2030 in the United States, and is intended to help policymakers understand the benefits of a federal budgetary package that includes a Clean Energy Payment Program. This reliable clean energy future would generate up to 1 million net new jobs through 2030 and up to 317,000 avoided premature deaths through 2050.
A new meta-analysis of seven clean energy policy studies led by researchers at prominent universities, think tanks, and non-governmental organizations finds strong agreement on the feasibility of achieving approximately 80 percent clean electricity by 2030 in the United States, as well as the immense economic and health benefits of a rapid clean energy transition.
New research shows used electric vehicles in California are cheaper to own than comparable used gas-powered cars over an average ownership period, and are up to 40 percent cheaper when the maximum incentive under the state’s Clean Cars 4 All program is applied, paving the way for adoption by lower and middle-income consumers. The report also includes policy recommendations for accelerating electric vehicle adoption and creating good-paying jobs.
This research report examines the causes and consequences of the widespread Texas “Big Freeze” power outages, finding that ERCOT’s market design failed to prepare the state for such a crisis and to acceptably manage the crisis, and identifying lessons learned for policymakers in Texas and elsewhere to prevent future crises.
New modeling using the Colorado Energy Policy Simulator finds the state is off-track for its own climate goals with emissions likely to decrease just 18 percent by 2050. But strategic building, industry, and transportation sector policies would put Colorado on a 1.5° Celsius pathway, generate more than 36,000 job-years annually, and increase state GDP by $7.5 billion per year in 2050.
This analysis of U.S. coal plants found 72 percent of existing U.S. coal capacity and 80 percent of existing U.S. coal plants are either more costly to continue operating compared to building new nearby wind or solar plants or are slated to retire in the next four years. The report provides policy recommendations to accelerate the transition to a cleaner, cheaper grid and is accompanied by a dynamic visual interactive.
This report highlights the consensus among recent studies that a national clean electricity standard of 80 percent by 2030 would stimulate economic growth, create hundreds of thousands of new jobs, protect public health, and promote environmental justice, without compromising electricity reliability and affordability.
New modeling uses the latest renewable energy and battery cost data to show achieving 80 percent clean electricity by 2030 is technologically and economically feasible without raising customer costs and would stimulate $1.5 trillion in investments and avoid 93,000 premature deaths by 2050.
New Energy Policy Simulator modeling shows a relatively small set of policies to achieve a 50 percent reduction in U.S. emissions by 2030 relative to 2005 levels could increase U.S. GDP by $570 billion per year in 2030 and by $920 billion in 2050 and create 3.2 million new job-years in 2030 and nearly 5 million new job-years in 2050, while avoiding more than 45,000 premature deaths and 1.3 million asthma attacks annually by 2050.
New research shows not only is it technologically feasible to electrify every new car and truck sold in the U.S. by 2035, it would also save consumers $2.7 trillion and support more than 2 million jobs, but these benefits will not be realized without smart policy.
Electrifying every new car and truck sold in the U.S. by 2035 would save consumers $2.7 trillion and create more than 2 million jobs by 2035, but these benefits will only be realized with greater policy ambition including strong national fuel economy and tailpipe emissions standards for all vehicle classes.
New modeling using the Nevada Energy Policy Simulator finds the state is off-track for its own climate goals with emissions likely to increase 12 percent by 2050. But strategic building, industry, and transportation sector policies would put Nevada on a 1.5° Celsius pathway, generate 5,500 job-years annually, and increase state GDP by $800 million per year in 2050.
Accelerated clean energy deployment and ambitious climate policies have created China’s carbon neutral opportunity for economic growth, a lower-cost electricity system, energy security, cleaner air and water, and more sustainable cities. Realizing these benefits hinges on policies including a well-designed price on carbon, clean energy standards, and green finance.
New modeling using the Minnesota Energy Policy Simulator finds a newly proposed clean energy standard would cut statewide emissions nearly 20 percent by 2050, but strategic policies in the building, industry, and transportation sectors would put Minnesota on a 1.5° pathway, generate 39,000 job-years, and increase state GDP by more than $11 billion per year.
This report uses the Energy Policy Simulator to model two illustrative scenarios showing that a ten year-delay implementing climate action putting the U.S. on a net zero path by 2050 increases the cost of decarbonization by nearly three quarters, showing why we must adopt strong carbon emissions reduction policies to avoid catastrophic climate change impacts.
New modeling using the Virginia Energy Policy Simulator finds the Virginia Clean Economy Act will cut statewide emissions nearly 35 percent by 2050, but strategic policies in the building, industry, and transportation sectors would put Virginia on a 1.5° pathway, generate 12,000 job-years and increase state GDP by more than $3.5 billion per year.

This first-of-its-kind report shows how a Southeast U.S. RTO/competitive wholesale electricity market would generate $384 billion in economic savings, create 285,000 clean energy jobs, and reduce electricity sector emissions 37 percent by 2040.
Policymakers and utility executives must rapidly focus on how to finance the transition away from uneconomic generation assets while creating earning potential for utility shareholders. This issue brief explores an emerging model for refinancing the 22.5 GW of existing coal plants that will be uneconomic compared to building new local solar in 2025, as of 2018.
This brief explores the role of resource adequacy in the clean energy transformation: How the clean power transformation challenges grid resource adequacy planning and management paradigms, how fossil fuel incumbents exploit resource adequacy challenges to electric grid reliability, and why changing perception about resource adequacy must be a top priority for climate mitigation.
Energy Policy Simulator modeling shows a subset of the policy recommendations issued by the House Select Committee on the Climate Crisis will put the U.S. on pace for net zero carbon dioxide emissions before 2050, while generating nearly $8 trillion in monetized health and climate benefits.
Modeling of California’s Advanced Clean Trucks rule shows it will generate more than $7 billion in savings through 2040, yielding tremendous public health benefits valued at $9 billion dollars. When using a battery cost closer to those observed for passenger vehicles, these savings rise to more than $12 billion through 2040.
New research shows plummeting renewable energy and storage prices mean the U.S. can reliably reach 90 percent clean electricity by 2035 at no extra cost, supporting 530,000 new jobs per year, and cutting economy-wide emissions 27 percent.
This report outlines policy recommendations for Congress, federal departments and agencies, national laboratories, governors and state legislators, public utility commissions, and wholesale electricity markets to reach 90 percent clean electricity by 2035 in the United States.
This research note compares Energy Policy Simulator outputs across three different GDP outlooks and finds that short-term emissions are dependent on the severity of COVID-19 impacts, with 2020 U.S. emissions reductions ranging from 7 to 11 percent relative to 2019. Emissions will likely approach pre-COVID-19 levels by 2025, and COVID-19 is not likely to have a material impact on annual emissions in 2030 or cumulative emissions through 2050.
When utilities procure generation through non-ideal processes biased against clean energy, they result in portfolios with higher consumer costs and carbon emissions. This report outlines how “all-source” procurement allows technologies to fairly compete to meet utility needs, reducing costs and emissions, with detailed case studies from recent utility procurement processes.
Achieving climate stabilization requires we fully decarbonize global industry, and reaching net zero industrial emissions by 2050–2070 is necessary to limit global warming to 2°C, as industry generated 33% of global anthropogenic emissions in 2014. This research paper outlines the technical measures and policies to boost technological deployment and make net zero industry a reality.
The rush to build more than 60 gigawatts of natural gas plants and pipelines risks tens of billions in investment and a trillion dollars in consumer costs by 2030. This report outlines these evolving risks for shareholders, lays out investor strategies to accelerate the clean energy transition, and shows how clean energy cuts utility investment risks from over-reliance on natural gas while providing new growth opportunities supporting decarbonization.
EI partnered with ACEEE to identify states using performance incentive mechanisms (PIMs) for strategic demand reduction (SDR).
New research using the California Energy Policy Simulator finds California climate policies risk overshooting the state’s 2030 goal by between 13-43 MMT CO2e, but six policy fixes can hit the goal and deliver $22 billion in benefits.
Hong Kong currently does not have a long-term decarbonization strategy or target beyond 2030, but must formulate a long-term decarbonization plan to conform with short- and medium-term actions. World Resources Institute and Civic Exchange collaborated with Energy Innovation to develop the Hong Kong Energy Policy Simulator (EPS) to provide technical support for developing Hong Kong’s 2050 deep decarbonization strategy. This technical note describes the structure, input data sources, outputs, limitations, future development, and online interface of the Hong Kong EPS.
At least 36 GW of uneconomic coal-fired capacity is forecast to be retired by 2024. These policy briefs highlight how to help utilities balance stakeholder interests, facilitate the financial transition away from uneconomic coal, and help states embrace clean energy.
Utilities can be regulated to address their monopsony market power so that competitive solicitations result in many bidders and low prices for generation projects, creating benefits for consumers and utility shareholders. This brief highlights lessons from Colorado’s experience leveling the playing field to ensure competitive bid results in the state are achievable as part of the financial transition away from uneconomic coal generation.
Energy Innovation’s net zero emissions by 2050 illustrative policy package helps put the United States on a pathway to achieve the Paris Agreement goals and abates more than 6 Gt of emissions a year by decarbonizing America’s industrial, transportation, electricity, and buildings sectors.
The Trump Administration’s proposed fuel economy standard rollback and emissions standards freeze will harm consumers and the environment. This research note finds the proposal would cost the U.S. economy up to $400 billion through 2050, increase U.S. emissions up to 10%, and gasoline use up to 7.6 billion barrels through 2035. It would also cost Canada up to $70 billion through 2050 and increase its emissions up to 11% by 2035.
Competitive wholesale electricity markets are at a turning point. These papers outline questions emerging about wholesale market reform and introduce two pathways for markets to evolve.
America has entered the “coal cost crossover” where existing coal is more expensive than cleaner alternatives. Today, local wind and solar could replace 74 percent of the U.S. coal fleet at an immediate savings to customers. By 2025, this number grows to 86 percent of the coal fleet.
This research paper explores energy transition impacts on competitive power markets, finding every U.S. organized power market except ERCOT is oversupplied due to seven oversupply drivers. Oversupply slows decarbonization, but market operators and load serving entities have options to responsibly manage the power system through this transition. The full version of this paper was published in the March 2019 issue of Current Sustainable/Renewable Energy Reports, and is available upon request. https://link.springer.com/article/10.1007/s40518-019-00123-6
By analyzing publicly available financial information, policymakers and utility stakeholders can identify where running existing fossil fuel generation costs more than replacing it with new wind or solar. A suite of financial instruments can facilitate and reduce costs of this financial transition away from fossil fuels toward clean energy. This brief uses Colorado’s experience transitioning from coal to clean energy as a case study analyzing existing generation costs, and introduces financial tools to help electric utilities that own fossil generation manage the clean energy transition.
Early retirement of uneconomic coal assets can improve shareholder earnings if a utility is allowed to reinvest capital in new renewable energy generation. When building new renewables is cheaper than operating existing coal, swapping steel for fuel adds value for investors, customers, and the environment. This brief addresses equity shareholder perspectives and suggests how potential funding sources can mitigate impacts on communities and workers affected by early plant retirements while improving environmental performance.
Depreciation accounting recognizes asset value reduction over time. For coal plants, depreciation determines the value remaining when plants retire early. Depreciation is an important tool for transitioning away from older assets, such as coal plants, to cheaper resources, such as wind and solar. This brief reviews how depreciation schedules affect utility earnings and ratepayer costs, as well as other stakeholder interests.
When electric utilities transition from fossil fuels to clean energy, they must address unrecovered investment balances. Depreciation schedules are often accelerated to line up with earlier-than-planned retirement dates, which can increase short term consumer rates. This brief reviews how utilities can refinance undepreciated balances on plants in service to lessen the consumer rate burden, primarily through replacing some portion of equity with corporate debt.
Navigating Utility Business Model Reform seeks to establish foundational elements of different reform options, poses key questions to explore their applicability, identifies illustrative experiences for ideas and concepts, and explores policy implementation options to help spur action. Navigating Utility Business Model…
Energy Innovation’s new book Designing Climate Solutions is the first policy manual for low-carbon energy and is the first book to identify the 10 policies, applied to the 20 highest-emitting countries, that can reduce emissions fast enough to stay below 2°C of global warming and avoid the worst impacts of climate change.
Cement manufacturing produces 5.6% of global CO2 emissions. This research finds that capturing 80% of cement’s process emissions (and no thermal emissions) by 2050 can make cement carbon-neutral, as natural carbonation offsets remaining emissions. If thermal fuel supply were fully decarbonized by 2050, a 53% process emissions capture rate achieves carbon-neutral cement. Higher capture rates than these would provide net negative CO2 emissions and the possibility that simply making concrete could reduce atmospheric CO2 concentrations.
The Trump Administration has proposed directing funds to keep uneconomic coal and nuclear plants online. This research note assesses the $2 billion in subsidies that would be needed to keep the six plants owned by FirstEnergy in the Ohio Valley in operation, and finds the funds would be better spent supporting economic transition for the power plant communities and displaced workers.
UPDATE: We updated this analysis in August 2019 to incorporate newer data and assumptions in a new research note. The Trump Administration’s proposed fuel economy standard rollback and revocation of California’s ability to set vehicle emissions standards will harm consumers and the environment. This research note finds the proposal would cost the U.S. economy up to $457 billion through 2050, while increasing U.S. emissions up to 11% and gasoline use 20% through 2035.
This research paper outlines how competitive electricity markets are undergoing a rapid transformation from systems with large, inﬂexible baseload resources to ones with smaller, modular, variable resources. Enabling a smooth transition requires making the grid more ﬂexible, and a signiﬁcant amount of unused ﬂexibility exists in the system, but harnessing it requires market rule changes.
This research paper reviews what it would take to achieve energy system decarbonization, including parts of the energy system that are particularly difficult to decarbonize including aviation, long-distance transport, steel and cement production, and provision of a reliable electricity supply. The full version of this paper was published in the June 2018 issue of Science http://science.sciencemag.org/node/711939.full
Carbon pricing is increasingly used to reduce carbon emissions through carbon taxes and cap-and-trade programs, and the most important new development in carbon pricing is China’s national carbon market. This research note discusses how California’s “consignment auctioning” approach to allowance distribution provides an option for Chinese policymakers to introduce auctioning while cushioning economic effects on covered entities through free allocation.
“Emerald Cities: Planning for Smart and Green China” is the first comprehensive manual detailing how to build a sustainable city from the ground up in China, laying out green building and urban sustainability practices for low-carbon city planning and construction in China and abroad. The manual proposes 10 principles to help set a new development direction for Chinese cities and aims to establish green, healthy and economic vibrant cities, while solving pollution and livability challenges faced by China’s cities. The manual is available for free download in English and in Chinese.
Canada’s government has proposed the ambitious Pan-Canadian Framework (PCF) policies to help achieve its emissions reduction goals. The Canada Energy Policy Simulator was created to evaluate the PCF, and this report finds that even if the PCF is fully implemented, Canada’s 2030 emissions will miss its goal by 161 million metric tons (MMT), a gap 3.7 times larger than the government’s 44 MMT predicted shortfall. Extending and strengthening PCF policies would allow Canada to come much closer to its target, save money, and save human lives.
The U.S. Chamber of Commerce’s proposal to raise the federal fuel user fee (gas tax) $0.25 per gallon has driven debate over U.S. transportation funding. This research note finds the proposal would generate $1.1 trillion in federal government revenue by 2050 and cost U.S. drivers $40 billion per year by 2025. It would also increase annual EV sales by 210,000 per year and add 2.5 million total additional EVs to U.S. roads while reducing annual fuel consumption 30-38 million barrels and cutting total fuel use more than 1.3 billion barrels, both by 2050, and would equal a national carbon tax of $29 per ton.
New data show that carbon emission allowance oversupply has grown in the Western Climate Initiative cap-and-trade program linking California, Ontario, and Quebec. Left unaddressed, this oversupply is estimated to reach 270 million metric tons by 2020, resulting in higher than intended emissions. This report details how a straightforward lowering of future caps to counter early oversupply solves the problem.
Utilities should consider two business models when considering their role as distribution system operators (DSO). In the first, the utility would represent a DSO and run the centralized system, with full visibility into available resources for real-time load balancing and responsibility for construction and maintenance, and be compensated on meeting policy goals. In the second, the utility owns the system, reveals its needs, with a separate DSO entity meeting those needs and integrating all assets including DERs.
DOE’s cost-recovery proposal would roil U.S. wholesale power markets to keep uneconomic coal and nuclear generation operating. This report finds DOE’s proposal could cost customers up to $10.6 billion per year, with up to $7.3 billion borne by customers in PJM Interconnection. More than 80% of the coal generation subsidy would go to just five companies and nearly 90% of the nuclear generation subsidy costs would go to just five companies.
America’s electricity market operators are increasingly looking for ways to make their systems more flexible as more renewables, flexible demand resources, and energy storage come online. This report outlines which types of flexibility are needed for grid reliability, offers advice on how markets can ensure sufficient flexibility, and will help identify ways to manage the grid with a rapidly evolving mix of resources.
On the one hand, utilities need to collect and convey data about where value lies on their distribution systems – focusing on integrated distribution planning as a means to get the most out of DERs and grid modernization investments. As…
A presentation on the future of U.S. wholesale markets, three potential outcome, and related implications for retail power markets from Energy Innovation Vice President Sonia Aggawal.
New modeling using the Energy Policy Simulator forecasts electric vehicle sales will make up 65% of new light-duty vehicle sales by 2050, and could reach up to 75% by 2050 in the event of high oil prices or strong technology cost declines. The modeling includes expected market share expansion and penetration levels, the effects of internal factors like battery prices, external factors like oil prices and government policy support, and related national electricity demand.
Restructured wholesale electricity markets serve stakeholders by providing three principal services: economically efficient real-time dispatch, incentives for resource adequacy and long-term cost recovery. Because at least two of these functions happened dynamically through market forces, future scenarios for clean, affordable…
A court decision to vacate EPA’s rule to reduce hydrofluorocarbons (HFCs) could cost at least 3.6 billion metric tons avoided emissions through 2050 and limits U.S. options to fully implement the Kigali Amendment to the Montreal Protocol, which could cut cumulative U.S. emissions by 9.5 billion metric tons. This research note report analyzes potential impacts of the court decision, as well as alternatives for the U.S. to fully implement the Kigali Amendment.
This series of reports offers national-level policy recommendations that are aimed at improving energy efficiency. Since 2010, the International Energy Agency (IEA) has published reports in this series that focus on building energy codes, effective city planning, transportation sector fuel…
For the first time last year, a portion of the current vintage allowances offered in one of the California-Quebec cap-and-trade program’s quarterly auctions went unsold. This report provides a quantitative analysis of the supply and demand for carbon allowances in the linked California-Quebec cap-and-trade program to help discern the role that temporary or systemic oversupply may be playing.
The Northeastern U.S. is simultaneously home to the most ambitious regional renewable energy goals and the most constrained lands in the U.S. This paper builds upon past work on siting policy to examine siting solutions tailored to meeting renewable energy demand in a land-constrained region. Along with creative new approaches to renewables siting, the paper examines four approaches to reduce the need for land-intensive utility-scale renewables.
Every utility regulatory model has embedded incentives. This list is intended to help state policymakers and other stakeholders pinpoint questions they can ask and answer to explore how incentives from cost of service regulation and performance regulation relate to today’s power system goals.
The prospect of large grid modernization investment triggers a key question – is it worth it? As different states consider upfront investments in modernizing the grid, regulators need ways to ensure utilities maximize the potential benefits of grid modernization. This white paper provides program design considerations and metrics that can guide utility investment and increase the chances that customers get the most out of grid modernization efforts. A version of the paper was also published in Electricity Policy, and can be found here.
Paris marked an unprecedented political commitment to reduce the threat of climate change. Marrakesh is the moment to move from what we must do to how we will do it. This collection of resources includes reports on how to design and implement policies to meet the world’s climate goals, as well as design guides for four of the world’s top energy policies: 1) carbon pricing, 2) vehicle performance standards, 3) vehicle and fuel fees and feebates, and 4) urban mobility policies. More of these policy-specific guides are coming soon.
How can Mexico achieve its climate targets and work toward the Paris Agreement goals? This working paper addresses this question by identifying and evaluating the key climate and energy policy options available to Mexico to support the implementation of its INDC. The analysis shows that Mexico can meet its unconditional and conditional targets while at the same time saving money and lives.
Urban Sustainability Planning for Mexico City offers recommendations for the City’s new Urban Development General Plan. Energy Innovation joined the government of Mexico City, colleagues from the Mario Molina Center for Energy and the Environment, and other Mexico City-based experts for this project, which draws on the framework developed in 12 Green Guidelines.
This report provides insight into which climate and energy policies can most cost-effectively drive down China’s emissions. The report’s recommendations are based on results from the Energy Policy Simulator (EPS), which assesses the combined effects of 35 climate, energy, and environmental policies on a variety of metrics.
This paper synthesizes the reasons for California’s successful climate policy. It considers the relative strengths and weaknesses of different types of policy, concluding that performance standards have led in reducing statewide emissions. Market failures beyond the lack of a price on carbon mean the best policy approach combines the three types of policy: performance standards, economic signals, and research and development (R&D).
This paper explores which regulatory models align utility profit with societal value under scenarios in which traditional, utility-owned solutions may not be optimal for customers. The cases in this paper offer insight into whether and how cost-of-service regulation and its alternatives (performance incentive mechanisms and revenue caps) can align utility shareholder values with societal values.
The grid will require a substantial transformation as more renewable sources come online. Some critics argue technological, financial, and institutional barriers will prevent significant decarbonization of the power sector, but four common clean energy myths are easily debunked by facts and real-world experiences showing the feasibility of a low-carbon energy future.
New York Public Service Commission (NYPSC) released a new order as part of its Reforming the Energy Vision, which includes ambitious language on performance-based compensation and improved rate design. Specifically, the NYPSC adopts an outcome-based approach to measuring performance, focusing on peak demand reduction and energy efficiency as key metrics to tie to revenue in the short term.
This review offers a comprehensive meta-analysis of utility programs and industry research on time-based and demand charge rates. The research identifies key design decisions and their effect on outcomes such as peak reduction, total load reduction, and customer acceptance. The review provides detailed and broad empirical evidence to guide conversations as different regulators consider changes to net energy metering or other peak reduction programs.
This study highlights some of the challenges and opportunities for the distributed solar PV (DPV) market arising from recent rate reform efforts, particularly demand charges and fixed charges. For example, it finds that immediate elimination of net energy metering (NEM) in all states could reduce residential DPV deployment 30 percent by 2050, while universal availability of NEM would increase residential deployment by roughtly 40 percent.
The climate problem is enormous: It threatens much of modern civilization, and its principal source, in burning hydrocarbons, is embedded in most of the modern economy. But a handful of insights, grounded in careful math, can clarify the situation, and point out a straightforward path to a reasonable climate future. This paper cuts through the clutter, and points to a reasonable, cost-effective solution to climate change, with clear steps to get there.
Given the momentum toward performance-based regulation across the country, these briefs provide perspective on how regulators might decide to design performance incentive mechanisms for success.
This white paper is the first in our Incentive Mechanism Design, series, which offers perspective on how regulators might decide to design performance incentive mechanisms for success. The paper examines a straw proposal for a new performance incentive to motivate utilities to reduce peak demand–a driver of investment in the electricity system–improving the affordability and environmental performance of the electricity system.
This white paper is the first in our Incentive Mechanism Design series, which offers perspective on how regulators might decide to design performance incentive mechanisms for success. The paper explores different approaches to simplify the measurement of energy efficiency savings to better align utility incentives with efficiency outcomes. These metrics can be helpful for many states where utility revenue is linked to energy efficiency, but their programs are bogged down in tedious and controversial evaluation, measurement, and verification requirements.
This white paper is the first in our Incentive Mechanism Design series, which offers perspective on how regulators might decide to design performance incentive mechanisms for success. The paper examines California’s Risk-Reward Incentive Mechanism (RRIM) as a case study to show that, while counterfactuals may be appropriate as an adjustment mechanism, they can also lead to unfair outcomes and unnecessary regulatory conflict.
This year’s annual report on Renewable Portfolio Standards (RPS) highlights these state-level targets are continuing to drive the majority (60 percent) of new renewable energy generation in the U.S. Compliance with these targets remains high (95 percent), while cost premiums in 2014 only resulted in an average 1.3 percent increase in customer bills.
This issue brief examines the potential benefits of expanding CAISO’s footprint to include other Western balancing areas through the lens of improved economics, renewable power integration, and conventional power plant retirements. The report is consistent with recommendations for policymakers articulated in Planning for and Investing in Wires. The report, summarized here also makes the case against a capacity market for a Western RTO recognizing, as Texas did, that it can be a lifeline to inefficient, old, uneconomical plants.
An abundance of new technologies are now available to produce cleaner, cheaper electricity. But in order to take advantage of them, system operators must build a flexible electricity grid. This paper reviews the types of resources that can deliver grid flexibility and provides case studies and recommendations for how to incorporate flexibility into grid systems.
This chapter in Future of Utilities – Utilities of the Future explores the nature of the customer-grid interface from the point of view of the customer. Customers are reconsidering the compromises they make given their new options for distributed energy services. This chapter exposes the underlying nature of the transactions happening at the customer/grid interface. The chapter uses analogies from the commerce and finance world to describe the currency-like features of electricity, and proposes ways of integrating new transactions into a future “fractal” grid.
This report provides survey results on the future of the electric utility, according to over 400 U.S. electric utility executives. Responses indicate that the industry’s most pressing challenges are an aging workforce and infrastructure, while they find the biggest growth opportunities in distributed energy resources, customer relationships, and transmission. Additionally, utilities plan to transition away from vertically-integrated models and toward distributed, service-based models. This SlideShare presentation highlights key findings from the survey.
Advanced Energy Economy’s new encyclopedia of advanced energy technologies surveys more than 50 advanced energy technologies that work to make the grid more reliable, cheap, and clean. This includes “technologies for electricity generation, electricity delivery and management, building efficiency, water efficiency, transportation, and fuel production and delivery.”
This policy toolbox is designed to improve distributed solar PV access for low-income customers. It identifies four principle barriers to low-income participation—cost, physical barriers, housing conditions, and market forces—and identifies dozens of solutions that address these barriers. Examples include on-bill financing, community/shared solar, green banks, and federal best practice networks. The report includes case studies from California, New York, Colorado, D.C., and Massachusetts, which have put these principles and recommendations into successful action.
This data analysis finds that over America’s clean energy sector now employs more than 2.5 million people. The majority of these jobs come from energy efficiency (1.9 million), and a significant portion come from solar (300,000) and wind (77,000). The solar industry in particular has experienced a 20 percent job growth rate for three years in a row, and is estimated to add 220,000 new jobs in coming years due to the Investment Tax Credit’s extension alone.
This paper offers a set of recommendations for enabling demand response in order to fully participate in Europe’s wholesale markets. In the short term, it recommends electricity prices should begin to reflect time-varying value of energy, and wholesale markets should establish a right for demand response to participate. In the long term, policymakers should mandate time-varying pricing for all customers; adopt codes and standards encouraging smart appliances, EVs, and in-home automation; reform utility business models to encourage demand response; and improve local value signals via integrated distribution system planning.
This factbook provides data-driven insight into a variety of industries that are contributing to the United States’ transition to a low-carbon economy. It provides a ‘birds-eye view’ of the entire U.S. energy sector, then breaks out subsequent chapters to cover energy-related topics in specific economic sectors. It concludes with cross-sectoral themes recent events and conditions in the U.S. and globally.
This report identifies objectives for demand response, explains the challenges in addressing them, and makes recommendations to policymakers, practitioners, and stakeholders. These include: expanding the understanding of demand response’s dual role as a supply resources and load reduction, increasing retail-wholesale coordination, improving planning, optimizing rates, valuing location, and improving verification.
This report is an update to a 2014 analysis that shows how grid managers can address the so-called “duck curve” caused by high penetrations of solar and wind power. A “flying duck” refers to shifting the late-afternoon and morning peaks to decrease the need for fast-ramping resources. The report outlines 10 strategies, including demand response, storage, time-variant rates, and retiring inflexible generators with high minimum run requirements.
This report offers perspective from five leading utilities on the challenges and opportunities for planning around distributed energy resources (DERs). It points out how existing distribution planning is insufficient to take advantage of the value of DERs, and suggests an iterative approach to improve planning. One major change will be incorporating incentive-based DER deployment into planning via new modeling approaches that can capture the complexity of a two-way distribution system.
This report uses California utilities’ Distributed Resource Plans as case studies to assert that current utility planning processes are leaving billions in potential benefits from distributed energy resources (DERs) on the table, and ought to be updated. It highlights regulatory models, utility incentives, and inadequate modeling of benefits as culprits for inefficient DER integration.
This study investigates how California’s electric sector can help achieve deep reductions in greenhouse gas emissions. Modeling results from Phase I of the study reveal that the state can reduce emissions by more than 50 percent below 2012 levels with minimal rate impact, minimal renewables curtailment, and at not cost to reliability. Phase II adds new insight, adding detailed flexibility analyses and examining the effects of drought and different resource mixes on the grid.
This factsheet outlines the financial options for meeting the COP21 agreement to limit global warming to 2 degrees Celsius or below, finding that global investment in new renewable electric power generation will need to reach $12.1 trillion in the next 25 years. Assuming “business-as-usual” will bring in $6.9 trillion in renewables investment, this leaves a “gap” of $5.2 trillion that must be additionally invested to reach the 2 degree target.
This report retrospectively examines the costs, benefits, and other impacts of all state renewable portfolio standards (RPS). The study finds that meeting RPS compliance reduces greenhouse gas emissions, air pollutant emissions (sulfur dioxide, nitrogen oxides, and particulate matter), and water use. These reductions equate to $7.4 billion in benefits. Other economic impacts include jobs growth and price reductions for wholesale electricity and natural gas.
This white paper recommends that modeling done by transmission planners and other stakeholders meet four minimum standards to “conduct effective modeling of the CPP”: (1) stakeholder engagement and transparency, (2) study methodology and interactions between studyies, (3) study inputs, sensitivities, and probabilistic analysis, and (4) tools and techniques. The standards will help avoid studies that produce unfounded reliability and cost findings.
The 3rd Annual Grid Modernization Index ranks and assesses all 50 states and Washingto, D.C. based upon the degree to which they have moved toward a modernized electric “Grid of the Future.” The Index measures states on a wide range of grid modernization policies, investments, and activities including state support, customer engagement, and grid operations.

This handbook intends to help distribution engineers understand and navigate the challengees of integrating high penetrations of photovoltaic (PV) generation into their service territories. The report describes the potential impacts, provides model-based analytics, and suggests potential mitigation measures.
This study finds the total national technical potential of rooftop solar PV equates to 39 percent of total national electric sector sales, nearly doubling previous estimates. Because the results are estimates of technical potential, they do not consider what would be required to integrate all the potential PV-generated energy into the power system. In practice, the integration of a significant quantity of rooftop PV into the national portfolio of generation capacity would require a flexible grid, supporting infrastructure, and a suite of enabling technologies.
Even the most well-intentioned energy policies will not meet their desired goals if they aren’t designed and implemented correctly. A handful of design principles, when properly applied, make for highly effective policies. This paper, an update from the original “Policies That Work” report, describes how to determine the right goals, choose the right policy approaches, and design and implement the specific policies to meet these goals.
Negotiations by the world leaders at the COP21 summit should be guided by California’s experience. This paper describes how performance standards and carbon pricing mechanisms have helped the state reduce emissions and increase renewable energy while creating economic growth, putting the state well on its way to achieving its emissions goals.
Over the past several years, the world has witnessed an upward trend in climate and clean energy investment. This has helped drive down costs of innovative low-carbon technologies, which has enabled their incredible market growth. In many situations, renewable energy sources, such as wind and utility-scale solar, are now cost-competitive with traditional fossil fuel sources. The following factsheet highlights the most current data on global investment in low-carbon technologies.
This article discusses the possible outcomes of the Supreme Court’s ruling on FERC Order 745. The authors acknowledge the importance of finding the true value of demand response, but argue that too much emphasis has been places on finding this precise value without sufficient evidence about how demand response providers will respond to price signals.
This report offers a roadmap for moving beyond 33 percent renewables, as required by SB 350, passed this year. While there are no clear signals that would suggest significant management issues with higher penetrations of renewables, the CPUC does recognize the growing need for ramping, handling over-generation, and additional ancillary services.
California can accomplish its goal of reducing carbon emissions 40% below 1990 levels by 2030 with proper attention to smart growth. By emphasizing better land use patterns, and supporting better transit and more walkable neighborhoods, carbon reductions of this magnitude are not just technically feasible, but would also save billions of dollars on infrastructure, fuel, and health costs while empowering economic growth and helping counter income inequality.
This paper presents case studies about performance management in publicly-owned utilities, drawing out concrete steps that can support municipal utilities, public utility districts, and cooperatives to adapt to changing technology and market trends. These steps – which involve taking “no regrets” actions, exploring evolutions in government, and considering more drastic action if performance lags – can enable POUs to deliver greater value to their customers.
CDBC’s Green and Smart Urban Development Guidelines highlight the key design features that make for a healthy, prosperous, and vibrant city.

In October 2015, Energy Innovation launched Energy Policy Solutions, an assessment of climate and energy policies to help meet decarbonization goals. We created a computer model, the Energy Policy Simulator, to quantitatively measure the cost and emissions impacts of more than 50 policies across all economic sectors. This page summarizes key findings from our model analysis, including recommended policy packages for meeting the U.S. 2025 emissions target and the Clean Power Plan target.
Energy Innovation’s Policy Solutions, based on transparent data and objective analysis, provide a roadmap to a clean energy future for America. Policy Solutions is a coherent set of the most cost-effective set of 15 policies to achieve the United States’ emissions reductions goals, and save hundreds of billions of dollars between 2016 and 2030.
Discover the most effective policies to decarbonize America’s economy at the lowest cost. The Energy Policy Simulator was designed to empower decision makers to find the best course toward a low-carbon U.S. economy. The Energy Policy Simulator works in real-time to measure the cost and emissions impacts of more than 50 climate and energy policies.
Energy Innovation identified a cost-effective package of six policies that the U.S. could use to meet the Clean Power Plan at a national average scale. This scenario actually exceeds the emissions goals in later years, as policies designed to meet earlier targets continue to reap benefits in later years, and saves the U.S. more than $40 billion between 2016 and 2030.
It pays to adopt smart energy policy sooner rather than later. If policymakers wait just four years (until 2020) to take action and want to achieve the same emissions reductions by 2030, they risk nearly $400 billion in additional costs. Policy implementation should start early to take advantage of natural capital stock turnover and the increased productivity of an efficient system.
This study identifies 13 services that batteries can provide, dividing each by the beneficiary: customers, distribution utilities, and bulk-system operators. RMI recommends that regulators require distribution utilities to examine DERs including storage as alternatives to traditional infrastructure investments, and that battery and DER developers collaborate with utilities and regulators to help them understand what values distributed energy storage can provide.
This study quantifies the benefits of full operational integration between California Independent System Operator (CAISO) and Pacificorp, a utility that spans six Western states. The study finds that market consolidation could produce between $3.4 billion and $9.1 billion in shared cost reductions in the first 20 years through better grid management and efficiencies gained by planning for the resource needs of a single system.
Renewables are projected to be the largest single source of electricity growth over the next five years, according to this report from the International Energy Agency (IEA). Falling costs and rapid adoption in Asia and other emerging economies are driving the trend, but the IEA calls for governments to reduce policy uncertainties that could slow further deployment of renewables.
This report covers planning, operations, market design, and oversight in the context of a high distributed energy resources future. The authors lay out a framework for thinking about these topics, as well as a set of steps that state regulators and policymakers could follow to get from today’s system to a future system served by a higher share of distributed resources.
This paper, an addendum to An Adaptive Approach to System Optimization, presents a series of case studies on various ways to integrate cost-effective distributed technologies that have run into outdated regulatory models. It identifies strengths and weaknesses associated with utility-owned and operated DERs, third-party-operated DERs, and customer-operated DERs.
California can accomplish its goal of reducing carbon emissions 40% below 1990 levels by 2030 with proper attention to Smart Growth. By emphasizing better land use patterns, and supporting better transit and more walkable neighborhoods, carbon reductions of this magnitude are not just technically feasible, but would also save billions of dollars on infrastructure, fuel, and health costs while empowering economic growth and helping counter income inequality.
This report shows an increasingly competitive utility-scale PV sector, with installed prices having declined significantly since 2007-2009, relatively modest O&M costs, solid performance with improving capacity factors, and record-low levelized PPA prices of under $50/MWh on average, making solar cheaper than existing generation in some regions.
This study demonstrates how location influences the carbon emissions benefits of renewable energy in different regions, and at different times of the day. The study incorporates the emissions intensity of the wholesale market as well as the resource potential in each state, and finds that solar subsidies are higher than the carbon benefits in the states examined, but wind subsidies are less than the carbon benefits in many regions. The study finds that energy efficiency is still the cheapest form of carbon reduction available in the electricity sector.
China’s power sector is undergoing major changes in order to meet ambitious goals for air quality, renewable energy, and carbon emissions. This paper from the Paulson Institute suggests market-oriented reforms that will help achieve the goals outlined in the government’s “Deepening Reform” policy document.

It takes a holistic approach to investigate the future pathway of global emissions, the direct risks arising from the climate’s response to those emissions, and the risks arising from the interaction of climate change with complex human systems. The assessment is divided into four parts covering 1) emissions trends and political and technological implications, 2) direct risks associated with climate change, 3) systemic risks, and 4) economical and ethical valuation of climate change.
This survey provides insights from senior-level utility executives from all over the world about trends and pressures facing the utility industry. It finds that utility executives overwhelmingly (97%) anticipate significant industry disruption by 2020. A majority of survey respondents anticipated distributed generation would achieve a 10-20% share of total generation by 2020, rising to 20-30% by 2030. In response, 2/3 of global executives agree that change to business models is becoming urgent.
This paper reviews the elements of basic rate designs, provides example rates, and contrasts rates that support vs. discourage distributed generation. It also touches on complementary policies for smart rate design, including incentive regulation (or performance-based ratemaking).
This report examines the impacts of net energy metering (NEM) and two competing feedback dynamics on U.S. distributed PV deployment through 2050 under different rate structures. The report confirms that rate structures with higher monthly fixed customer charges or PV compensation at low levels can dramatically erode aggregate customer adoption of PV. Moving toward time-varying rates may accelerate near- and medium-term deployment, but is estimated to slow adoption in the longer term.
This report argues for the Department of Interior to embrace a landscape-scale approach to development. It also outlines progress made in setting up a renewable energy program for public lands and summarizes some key remaining opportunities, including developing best management practices to minimize impacts during construction and operation, establishing mitigation measures to off-set impacts that cannot be avoided, and protecting areas that are too special to develop.
This analysis discloses CO2, NOx, SO2, and mercury emissions from the top 100 electric power producers in the U.S. These top 100 power producers accounted for 85% of the electricity generated in 2013. Several power producers in the Southeast have reduced CO2 emissions by a third or more since 2000. In addition, the report finds that the electric industry has cut overal NOx and SO2 emissions even as overall electricity generation and GDP have increased.
This resource book provides information about the economic, environmental, and social imperative for the Clean Power Plan. It begins with a handful of chapters covering the consequences of climate change as it pertains to human health, extreme weather events, national security, wildlife habitats, and more. NRDC emphasizes that all these consequences are far costlier than implementation of the Clean Power Plan. The last several chapters of this book describe why the Clean Power Plan is important and how it will benefit the public, the economy, and the power grid.
This working paper argues that facilitating interstate reduction strategies provides many types of benefits to states and regulated entities, including lowering compliance costs; reducing concerns about competition among jurisdictions; responding to changing fuel prices, weather, and other uncertainties; improving administrative efficiency; and enhancing alignment with regional electricity markets. Designing plans to be compatible will allow states to “opt in” to interstate compliance in the future without committing to it in the state plan.
This paper uses the National Energy Modeling System to evaluate alternative low-carbon electricity pathways. The authors find that the least-cost compliance pathway involves a combination of renewable and energy efficiency policies, plus a modest price on carbon that could be expected to result from the Clean Power Plan’s implementation. This pathway also produces substantial benefits including lower electricity bills, greater GDP growth, and significant reductions in SO2, NOx, and mercury emissions.
This paper describes Energy Innovation’s Energy Policy Simulator, a system dynamics model that assists in selecting policies that will allow China to achieve its emissions reduction goals. The model’s results find that China can peak its carbon emissions before its target year of 2030, and this is done most cost-effectively via a package of policies supporting a diverse set of technologies.
This paper argues that the financial “value engine”—the difference between a utility’s return on investment and its cost of capital—drives shareholder returns. Regulators should use this value engine to align utilities’ financial motivations with delivering value to customers and society.
This report provides context on the current status of the electric grid in the Western U.S. and summarizes some of the larger initiatives underway to upgrade Bulk Electricity System (BES) planning, operations, and markets.

This paper examines the impact of high shares of solar PV on the California system, reviewing the resources needed to maintain resource adequacy under a variety of scenarios. The report analyzes several options for relieving pressures portended by California’s famous projected “duck curve,” finding that interties to other regions provide the largest opportunity to mitigate the duck.
This paper examines electric utility business and regulatory models that can facilitate the power sector’s transition. It discusses the disruptive challenges to the current business model and how performance-based regulation can help. It outlines three options for the future utility business model – one where the monopoly role expands, one where the utility serves as a platform for distributed energy resources, and one where the utility purely provides electricity infrastructure.
This study presents and updated analysis on the earth’s global surface temperature, revealing that temperatures are higher than previously reported by the Intergovernmental Panel on Climate Change in 2013. These results counter the notion of a “hiatus” in rising global surface temperatures, concluding that warming trends within the 21st century closely match those from the second half of the 20th century.
This paper provides a framework for guiding the evolution of new utility business and regulatory models in a highly distributed energy future. The report breaks down the transition into two parts, the “profit achievement” spectrum (i.e. what products utilities are selling), and the “profit motivation” spectrum (i.e. what drives utility growth).
The report surveys what utilities and independent system operators (ISOs) with relatively high shares of variable renewable generation are doing to integrate those resources into their systems without compromising reliability. Brattle focuses on two case studies – the Electric Reliability Corporation of Texas (ERCOT) and Xcel Colorado. The in-depth case studies show ancillary service reform, improved forecasting, and other policy tweaks increased the flexibility of the system and enabled renewable integration beyond what is required by the Clean Power Plan.
This analysis finds that the United States can meet, and even surpass, its announced target to reduce greenhouse gas emissions by 26-28 percent below 2005 levels in 2025 with a comprehensive approach using existing federal laws and state action. After 2025, even deeper reductions will be necessary to avoid the worst impacts of climate change. The paper models two pathways that could reduce emissions 40–42 percent below 2005 levels by 2030, and 50-53 percent by 2040 with new legislation that establishes a price on carbon together with complementary policies across the economy.
This introduction the the journal, Mitigation and Adaptation Strategies for Global Change (volume 20, issue 5), describes current trends in China’s transportation sector, primarily the increased use of motor vehicles as a result of sprawling and car-focused urban development. Motor vehicles have increased China’s traffic congestion and air pollution. This introduction mentions the subsequent articles in the journal that cover solutions for cleaner and more efficient Chinese transport, including urban development, transport planning, vehicle fuel efficiency standards, vehicle emission standards, and electric drive technology.
This report analyzes a variety of environmental, economic, and power sector-related impacts of the EPA’s proposed Clean Power Plan, looking at a range of baseline cases and Clean Power Plan cases. The analysis finds that the Clean Power Plan would reduce power sector CO2 emissions between 29 and 36 percent by 2030, with most of the early emissions reductions coming from natural gas replacing coal and later emission reductions coming from the addition of renewable energy sources. Overall, electricity prices are projected to increase slightly (3-7 percent) at first, but will level off by 2030.
This report examines six modeling studies of EPA’s proposed Clean Power Plan, comparing estimated impacts on power costs and the structure of the power sector. These studies all predict the Clean Power Plan will lead to a decline in power generation and coal production. Though they also estimate no growth in renewables and nuclear beyond the business-as-usual scenarios, the studies do highlight the role of energy efficiency in minimizing cost impacts.
The latest report in MIT’s Future of series analyzes the potential for solar to compete against other resources to provide electricity. The report advocates for a carbon price on to account for externalities, and suggests new rate structures for residential systems to better account for distribution costs. It concludes that residential distributed solar adds between $5-19/kilowatt/year of distribution costs to the system.

During his recent inaugural address in early 2015, California Governor Jerry Brown announced a set of clean energy and climate goals to be met by 2030. For the last several months, Energy Innovation has engaged in policy analysis to produce three papers that provide guidance on how to achieve these goals.
It is becoming increasingly more realistic that many electricity customers, rather than defect entirely from the grid, will instead invest in grid-connected solar-plus-battery systems as a means of ensuring more stable pricing and reliability. This report describes how the configurations and economics for this type of system, known as “load defection,” would evolve over time, and what magnitude of customers, load, and revenue it could represent over time.
This report surveys existing data on current and historical methane emissions from oil and gas systems worldwide, highlights gaps and disparities in country-level data, predicts methane emissions growth through 2030 under a range of scenarios, and quantifies the impact of action from top-emitting countries to control their methane emissions.
This report highlights deficiencies in existing regional transmission planning conducted under FERC Order 1000, emphasizing that plans consistently fail to consider the full range of benefits that can be realized. It suggests scenario planning that anticipates potential resource needs and reliability concerns. The report concludes that the diverse benefits of a more robust and flexible transmission system are likely to exceed upfront costs in many cases where Order 1000 is currently insufficient.
In this presentation, the Bipartisan Policy Center offers insights from modeling the effects of the Clean Power Plan under six scenarios. The slides argue that the interconnected nature of the power system is important to consider when looking at the Plan’s costs and benefits. Multi-state collaborations and/or linked trading approaches will help contain the costs of compliance, as will states’ choices of energy efficiency policies
Author Antung Anthony Liu argues that carbon taxes that recycle revenues and cut taxes in other areas can be good for both economic welfare and growth because they are more efficient than other forms of taxation. The paper summarizes three advantages of carbon taxes, contending they are harder to evade than other taxes, less likely to distort market behavior, and act as a deterrent to the informal, untaxed economy.
Energy Innovation’s new report on California climate policy argues the state should adopt an ambitious 2030 target of 40% below the 1990 level of greenhouse gas emissions, and describes a method for how to get there. This strong yet achievable goal would get California halfway to its 2050 target in one-third of the time and help the state maintain its clean energy leadership at a time of unprecedented global commitments to fight climate change.
This report examines the impact of the Clean Power Plan on grid stability. The changing resource mix due to increased coal retirements and renewable energy will alter the pattern of power flows across the transmission system, requiring new lines, line upgrades, and reactive power devices to maintain grid stability. It concludes that across the country, the costs of these changes are likely to be minimal and pose no threat to reliability.
This paper recommends policy initiatives that California can take in order to meet Gov. Brown’s renewable energy, energy efficiency, and transportation fuel use goals for 2030. Recommendations include expansion of the Renewable Portfolio Standard, a carbon standard to decarbonize the electricity supply, and a new energy efficiency performance incentive for utilities.
This policy brief highlights the top policies that will enable California to meet its renewable energy, energy efficiency, and transportation fuel use targets in 2030. Policy recommendations in the brief pertain to the state’s cap-and-trade program, electricity sector, transportation sector, and methane sources.
Wind Vision analyzes scenarios of wind power supplying 10% of national end-use electricity demand by 2020, 20% by 2030, and 35% by 2050. Building on the 2008 “20% Wind Energy by 2030” report, this study assesses wind power’s costs, benefits, and impacts in the context of U.S. energy goals. The study concludes that deployment of wind power under the study scenario levels is both viable and economically compelling.
GTM’s latest research whitepaper assesses the different pathways to achieve a decentralized, distributed, and transactive electric grid. It identifies nearly 20 states in various stages of grid- and market-modernization, categorizing each state’s pathway as driven by consumers, regulations, or the market. The paper asserts that patterns emerge based on which group is driving the change.
This handbook describes how regulators can use performance incentive mechanisms to guide utility performance as new issues of resilience, technological change, and the expansion of distributed energy resources emerge. The work builds off of an initial report, New Regulatory Models, which describes examples of performance-based ratemaking in action.
This study models the effects of the EPA’s proposed Clean Power Plan. It analyzes the impacts of five key variables (natural gas prices, available renewable resources, energy efficiency, nuclear capacity, and available new combined cycle natural gas) on six key outputs (resource dispatch, CO2 prices, wholesale market prices, fossil steam capacity retirements, load energy payments, and compliance costs).
This report dispels the notion that renewable energy is driving up retail rates. DBL Investors examined the top ten and bottom ten states for renewable generation, finding that between 2002 and 2013, the average annual rate of change in retail electricity prices was lower in states that led on renewables. Key economic drivers of this conclusion include: the falling cost of renewables, mounting economic benefits from clean energy, and growing uncertainty for carbon-based fuels.
This report posits four factors for policymakers to consider when designing Value of Solar tariffs (VOST): transparency, predictability, a standardized calculation methodology, and a levelized cost for solar. Each of these factors addresses perceived shortcomings of the net energy metering and fixed charge structures that have been unable to accomplish sustainable compensation for the costs and value of rooftop solar and the grid.

Earth’s systems are reacting to climate change on different timescales and magnitudes. Many of the impacts of climate change are occurring so abruptly that there is little time to investigate solutions and react. Both abrupt and gradual climate changes can cross thresholds, or ‘tipping points’, forcing once-balanced systems out of control and beyond a point of remediation. This report examines existing knowledge about the likelihood and timing of abrupt climate changes, argues for the development of an early warning system to anticipate these changes before they occur, and identifies the shortfalls in climate science and measurement/monitoring practices.
