In a decision blasted by the coal industry as making the state "dangerously reliant" on natural gas, the Colorado Public Utilities Commission has approved an emissions-reduction plan for Xcel Energy that further expands the utility’s already extensive shutdown of coal-fired power plants in favor of gas-fueled generation.

Ringing what may be the death knell for the $3.5 billion Taylorville IGCC project, the Illinois Senate voted 33-18 in early January against authorizing construction of a coal gasification and power generating plant proposed in the state by Tenaska.

Coal mining, and related industries that consume coal, have attracted quite a bit of attention from the federal government as of late. Most of that attention has focused on how to further, or "better," regulate the industry. The EPA is now moving to regulate downstream conductivity of surface mining runoff.

On December 23, 2010, one day before the Yuletide season, when members of Congress, the media, and Tea Party activists are least likely to watchdog the federal bureaucracy, the U.S. Environmental Protection Agency (EPA) announced rulemakings to establish New Source Performance Standards (NSPS) for greenhouse gas (GHG) emissions from power plants and refineries. Or maybe "whispered" would be more accurate.

An unintended consequence of employing selective catalytic reduction and wet flue gas desulfurization to reduce nitrogen oxide and sulfur dioxide levels at coal-fired power plants has been unwanted sulfur trioxide (SO₃) emissions. Picking the right sorbent in the right amount can eliminate that problem.

In his State of the Union address on Tuesday evening, President Barack Obama set a new goal for the nation: To obtain 80% of its electricity from “clean energy” by 2035. But his definition of “clean energy” included “nuclear, clean coal, and natural gas” as well as “wind and solar.”

A federal district court judge on Thursday sided with environmental groups in a suit against the Environmental Protection Agency (EPA) and gave the Obama administration only 30 extra days to issue Maximum Achievable Control Technology (MACT) rules for large and small boilers, and solid waste and sewage sludge incinerators—not a year, as the agency had sought.

The New Mexico Supreme Court today ruled unanimously that freshly elected Republican Gov. Susana Martinez violated the state constitution when she halted publication of cap-and-trade rules that were adopted by the state’s Environmental Improvement Board (EIB) last year.

The European Union (EU) on Tuesday said it was waiting for member countries to confirm that minimum-security requirements had been installed in their emissions registries before reactivating its emissions trading scheme (ETS). The European Commission halted spot carbon trading last week for at least seven days after hackers stole emission permits from accounts in the Czech Republic and Austria.

Massachusetts–based Beacon Power Corp. on Monday said it had energized and grid-interconnected the first 8 MW of flywheel energy storage at its 20-MW frequency regulation plant in Stephentown, N.Y., bringing in the first commercial revenue for the company.
