The Supreme Court just blocked the EPA's rules for toxic pollution from power plants.

The life-saving standards would have limited emissions of mercury (a potent neurotoxin) from coal-fired power plants, along with harmful particulate matter as a bonus.

Alas...the energy industry argued that the agency conducted the cost-benefit analysis at the wrong stage of the process—a total technicality. New York Times
