Energy Policy Simulator modeling finds the Build Back Better Act’s fee on methane emissions is responsible for 60 percent of the Act’s reduction of industrial greenhouse gas emissions from 2023 to 2050 and would boost the economy, creating more than 70,000 jobs by 2050 and increasing gross domestic product by more than $250 billion from 2023 to 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.

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.

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.

Plummeting costs, as well as policy and technology developments, are making U.S. offshore wind a critical renewable energy resource. This research memo summarizes current and expected offshore wind developments and cost trends and recommends seven policies to help federal and state policymakers maximize its potential of offshore wind to achieve clean energygoals while strengthening the economy.

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.

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.

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.

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.

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.
