When—not if—we pass climate legislation, we will put the U.S. on a path toward a low-carbon electric generation sector. As part of this shift, we’ll need more transmission, including lines to wind and solar power plants that are sometimes located far from today’s power grid. The question is: How do we plan for these new lines and how should we pay for them?

There is an idea that has been around for a long time, at least since the fall of 1973: All that stands between the U.S. and an abundant energy future is a lack of spending on research and development. It is as though the Knights Templar could find the Holy Grail, if only the Pope would commit just a few more resources to the hunt.

Scuttling a high-profile “public nuisance” lawsuit, a federal appeals court has reversed a lower court ruling that required the Tennessee Valley Authority to accelerate plans to install pollution controls at four TVA coal-fired power plants to reduce the amount of pollution blowing into western North Carolina, saying the lower court decision could lead to other public nuisance suits that would wreak havoc on federal and state regulatory regimes for combating air pollution.

Saying they have “grave concerns” about the agency’s two-option proposal to regulate coal combustion ash, 31 members of the House Energy and Commerce Committee have urged the Environmental Protection Agency to continue to regulate coal ash as a non-hazardous waste, saying an EPA proposal to designate it as a “special” hazardous waste eligible for reuse would lead to costly and unnecessary management and disposal requirements.
