Behind the U.S. power grid, electricity markets are just as important as physical power plants and transmission lines. To expand the country's clean energy, the rules of the market will need to change.

What consitutes safe geologic storage? This is a key question for the IRS as it considers how to account for carbon capture and sequestration.

Pennsylvania's planned entry into the Regional Greenhouse Gas Initiative marks the first time a major fossil-fuel producing state has joined the cooperative, which aims to cap carbon dioxide emissions from electric power plants. It won't solve all the Keystone State's energy challenges, but it's a big step forward.

The latest anti-climate proposal from the Trump administration would weaken regulations on methane from oil and natural gas. Colorado, Pennsylvania, Massachusetts and California offer innovative solutions for curbing this growing emissions source.

U.S. solar power is poised to grow 12% this year, but so far Virginia hasn't been a big part of the boom. That could change as Virginia's cities and counties band together to find ways to implement renewable power and meet their clean energy goals.

The United States used more energy in 2018 than ever before. While clean energy powered some of it, 80% came from fossil fuels.

When it comes to climate change, producing more oil seems counterproductive. But a technology called "direct air capture," by removing carbon dioxide from the atmosphere, can lower emissions from oil until the day we get off fossil fuels.

Decisions from utility commissions across the country suggest natural gas' time as a "bridge fuel" may be short—renewables are already often preferred and cheaper.

More and more companies and cities are setting 100% renewable energy goals. But how and when these customers use the electricity they buy also matters. Here are five other things large energy buyers can do to help green the U.S. electric grid.

Nevada's new measure to strengthen its Clean Electricity Standard is the latest in a series of legislative moves to drive the transition to low-carbon energy in the United States. That makes it a good time to review the newest research and consider whether such standards are good policy.
