COAL POWER Direct

The conventional and oft-repeated truth is that wind generation directly reduces carbon emissions. Challenging the conventional wisdom has drawn much criticism from wind proponents, but the latest research has shown that wind has had, and will continue to have, negligible impact on the nation’s carbon emissions. The data are convincing and can no longer be ignored.

Wind electricity production must displace some existing generation. However, its relentless variability imposes daunting challenges for wind integration. Clever engineering schemes can mask the problem, but the data show that wind generation has and will continue to reduce carbon by negligible amounts, but at great expense.

The Environmental Protection Agency is expected to select its approach for future regulations regarding coal ash storage later this year. One option would be to continue classifying the waste as nonhazardous and leave enforcement with the states. Another option—the worst case for the power industry—would be a determination that coal ash is a hazardous waste, which would result in increased federal oversight and lawsuits.

The U.S. electric utility sector is undergoing a transformation unparalleled in its history. Extraordinary challenges, driven by the urgency of climate change and other market forces, are compelling the industry to abandon its century-old business model of building large, fossil fuel plants to sell increasing amounts of electricity.

In recent months, two noteworthy letters have been sent to Congress by eminent scientists examining the merits—or demerits—of biofuels in the climate debate.

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.

An Environmental Protection Agency proposal to tighten sulfur dioxide and nitrogen oxides limits in 31 states and the District of Columbia to address transported air pollution fails to give utilities and state air regulators sufficient time to develop rules and install controls, according to American Electric Power Co. Officials from the EPA and New Jersey-based Public Service Enterprise Group said utilities already had begun making investments to cut emissions and they believed the agency’s compliance schedule could be met.
