Progress Energy Carolinas will shut down its 170-MW W.H. Weatherspoon coal-fired power plant this fall, several years ahead of the originally announced retirement schedule. The decision follows an evaluation of system resource needs.

Dominion Virginia Power on Friday announced it would convert three 63-MW Virginia coal-fired peaking plants to biomass. The Dominion subsidiary said that while the switch would provide a boost to the local economy, it would also reduce nitrogen oxides, sulfur dioxide, mercury, and particulate emissions to “meet stringent new emission standards established by the U.S. Environmental Protection Agency.”

Sunflower Electric Power Corp.’s proposed 895-MW Kansas coal-fired power plant suffered another legal setback last week as a federal district court judge ruled in a lawsuit filed on behalf of environmental group Sierra Club that the U.S. Department of Agriculture (USDA) violated federal law by providing approval and financial assistance to the project without environmental review and pubic involvement.

The first Clean Energy Progress Report released today by the International Energy Agency (IEA) finds that while “impressive progress” has been made in developing clean energy technologies in recent years, demand for fossil fuels has continued to surge. Coal has met 47% of global new electricity demand over the past decade, “eclipsing clean energy efforts made over the same period of time,” the agency says.

An internal study released by the Bureau of Reclamation on Thursday found that the federal body overseen by the Department of the Interior (DOI) could generate up to 1 million MWh more power annually from 70 of its existing facilities in 14 states. The report was followed by an $26.6 million funding announcement by the DOE and DOI on Tuesday for research and development projects to advance hydropower technology, including pumped storage.

This web supplement to "Changing Winds: The Evolving Wind Turbine" examines the debate over the merits of the two most common wind turbine axis orientations.

Two years ago, Spain’s fixation on renewables and “green jobs” was praised by President Obama as a success story worthy of our emulation. How is Spain doing today?

As POWER closes this issue (March 15), 6,000 people have been confirmed dead and 10,000 others are still missing as a result of the magnitude 9.0 earthquake and ensuing tsunami that destroyed Japan’s eastern shore on March 11. At this writing, the country is battling a third cataclysm—the potential meltdown of several reactors at Tokyo Electric Power Co. (TEPCO’s) Daiichi nuclear power plant in Fukushima Prefecture.

Five new nuclear reactors were connected to the grid while construction of 14 others began in 2010, the International Atomic Energy Agency (IAEA) reported in early March. Around the world, a total 65 reactors with a net power capacity of 62.9 GW were in various stages of construction—almost half of them in China.

Geologists drilling an exploratory well in Iceland’s Krafla volcano in search of supercritical geothermal resources in 2009 unexpectedly uncovered a new way to harness energy from deep within Earth’s crust. It involves accessing shallow bodies of molten rock, which the geologists say could likely be found elsewhere in Iceland and around the world, wherever young volcanic rocks occur.
