Largely seen as fringe technologies just a decade ago, clean energy resources are becoming truly mainstream in the United States. Here are 12 charts that show the state of the clean energy revolution underway in the U.S. right now.

California is a bellwether state in environmental and energy matters. The most recent illustration is the promulgation of Assembly Bill 802 and The Clean Energy and Pollution Reduction Act of 2015.

Investor-owned utilities spent more than $98 billion last year, while electricity demand was essentially flat. So why are utilities spending so much money? And who is giving them the money to spend? In addition, why is that only “regulated utilities” are spending money?

For years, energy companies have couched the possible effects of climate change-related regulations in public reports to investors as “uncertain,” “difficult,” or “not possible” to reasonably predict. Now a probe by New York Attorney General Eric Schneiderman is raising questions as to whether the companies knew more than they were letting on.

In a new wrinkle to the revelation that Exxon Mobil knew about global warming for about 40 years, New York State’s attorney general is now investigating the company and others to ascertain whether they misled investors on climate change’s causes and ramifications.

The opening of an investigation of Exxon Mobil by the New York attorney general’s office into the company’s record on climate change may well spur legal inquiries into other oil companies, according to legal and climate experts, although successful prosecutions are far from assured.

Without a single, comprehensive tool for evaluating the costs and benefits for emissions reductions, policymakers are often left to cobble together expectations for various policies from a hodgepodge of reports and studies that rarely share the same data and methodologies. Last month, San Francisco-based think tank Energy Innovation (EI) unveiled its Energy Policy Simulator, a one-stop shop for testing dozens of decarbonization strategies in the U.S. economy and evaluating their costs.

Energy Innovation, a San Francisco-based think tank, has created what may be the coolest tool for energy nerds I’ve ever seen. It’s called the Energy Policy Simulator, and it lets anyone see the impacts of their energy policy choices on a whole range of outputs, including US greenhouse gas emissions.

Considering the magnitude of the climate change issue, commitments at the national scale are necessary if the world is to feel any sort of emissions reduction impact. That said, an efficient and effective way to meet these commitments comes from the cities within a nation.

Thanks to San Francisco-based clean energy think tank Energy Innovation LLC, we now have a grip on the 15 most cost-effective policies for accelerating US clean energy and reaching our 2025 decarbonization targets.

There’s a lot of data out there — sometimes it can seem like too much — and a lot of it is unreliable. Climate data visualizations can help you sort through the noise to get at the signal.

Two experts consider what the demand-response market will look like if the Supreme Court kills FERC’s landmark rule. While this ruling potentially affects DR in capacity and ancillary service markets, their exchange focuses on the future of DR in wholesale energy markets.

Energy Innovation’s Energy Policy Simulator lets you model over three dozen different energy policies—from fuel economy standards to extending the life of existing nuclear to rice cultivation measures—to see how much they will cost and what impact they will have on greenhouse gas emissions.

Emissions data, temperature data, fossil fuel extraction data: the climate debate is awash with numbers. But it can be hard to find answers in the mass of information. Here are seven tools that can help.

Think of it like a low-fi SimCity, except instead of municipal policy, you get to tweak nationwide approaches to reduce greenhouse gas emissions. The immensely detailed Energy Policy Simulator is a digital tool that shows the impact of an astonishing variety of climate change policies.

The new Energy Policy Simulator is a responsive, thought-provoking way to understand what kind of system would reduce U.S. greenhouse gas emissions, how much it might cost, and which individual energy policies really move the needle.

A new report from America’s Power Plan investigates the question, “who should own and operate distributed energy resources?” It turns out there there are many options for who can own and operate DERs—and any of them can work, as long as the revenue streams are designed or adjusted appropriately.

Comparing two regions with similar total installed wind capacity, WECC and Texas, demonstrates the importance of good transmission planning. The lesson for transmission planning is clear: if you build it, wind will come.

Los Angeles’ Mobility 2035 plan shouldn’t be feared by residents. It will help solve gridlock and create true mobility by creating more transportation options, which is the best way to solve traffic congestion in California, home to three of the five most congested metro regions in America.

To the untrained eye, beautiful skylines, impressive subway systems, and lively public parks characterize great cities. However, there are also a number of invisible design features that characterize the best cities – urban growth boundaries, transit-oriented development, walking and biking pathway density, and small blocks are among the most important of these design features.
