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.

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.

For as long as renewable energy has been a threat to the conventional power sector, it has been plagued by warnings that too much wind and solar would destabilise the grid. Intermittent renewable energies could never power advanced economies unless they were backed up by large-scale affordable battery storage — a technology that had always seemed a distant dream. Yet, the dream seems to suddenly be not only achievable, but imminent and inevitable.

The National Association of State Energy Officials (NASEO) released a working paper designed to provide states with ideas on low cost energy efficiency approaches that can help them address the U.S. Environmental Protection Agency’s new Clean Power Plan.

The Obama administration is continuing to carve out a middle ground when it comes to energy policy—satisfying neither environmentalists nor the energy industry in the process. This article summarizes Obama’s energy strategy and actions (arctic drilling, methane emissions regulation, Clean Power Plan, etc.), and discusses what else the President can do to solidify his energy legacy.

In early 2015, the Solar Electric Power Association (SEPA) announced its 51^st State Challenge, which called for energy experts to submit proposals for how energy markets could be created in a 51^st state with no preexisting regulations or market structure. This article discusses several of the crosscutting themes and insights from the Challenge’s top three proposals.

150 of America’s top energy experts today refreshed America’s Power Plan, a comprehensive policy toolkit designed to help federal and state policymakers, regulators, power market operators, as well as utility executives make smart decisions to steer the United States’ power sector transformation toward a clean, affordable, and reliable system.

The commercial and industrial solar power sector has not yet taken flight in the same way that residential and utility-scale solar has in recent years. But to many in the solar industry, that just screams opportunity.
