"A bill to strip U.S. EPA of its authority to regulate greenhouse gas emissions cleared its first hurdle today on the road to likely House passage."

"Americans worried about the pain of $100 U.S. oil should worry a lot more. Although $100 oil is the headline in U.S. newspapers, most refineries that supply fuel to service stations are paying the equivalent of a much higher price -- and those costs are already being felt when consumers fill up their vehicles."

"U.S. EPA's plan to give businesses another three years to show how they calculate their greenhouse gas emissions will weaken the agency's new reporting requirements and could be illegal, environmental groups said before yesterday's deadline to comment on the proposal."

"With the Obama administration required to put its plan for reducing toxic air pollution from coal-fired power plants on the table a week from today, the American Lung Association and other public health groups have started an early push to explain why U.S. EPA shouldn't flinch on the long-delayed rules."

"Recent studies suggest that smog-filled air kills more people and causes more breathing problems than previously thought, U.S. EPA scientists say in a new draft paper, but due to a procedural twist, the findings can't be taken into account as Administrator Lisa Jackson decides whether to set stricter limits than the George W. Bush administration chose in 2008."

The boom in cellulosic ethanol that was predicted four years ago never happened. Or hasn't happened yet. The idea of making ethanol from all manner of plant material other than corn still promises major net environmental benefits -- unlike corn ethanol, which doesn't do much for the environment. But a lot depends on oil prices, electric car sales, financing, and the economies of scale.

"Behind the feud between Greenpeace and Facebook over renewable energy."

"At least three of the Wisconsin state Senate Republicans currently demanding that public workers sacrifice benefits, wages and even collective bargaining rights for the sake of the budget have applied for and received hundreds of thousands of dollars in federal farm subsidies, a Huffington Post review of state and federal records shows."

The U.S. Supreme Court Monday issued the second ruling in recent days narrowing exemptions to the Freedom of Information Act -- and thus increasing public access to government information. In the case of Milner v. Department of the Navy, the court rejected an expansive interpretation of the FOIA exemption on personnel matters. The Society of Environmental Journalists had joined other journalism groups in a friend of the court brief urging a narrower exemption.

"Democrats have attempted to get Republicans to confront the science on climate change, in an effort to halt moves to block regulation of greenhouse gas pollution. But it's not clear that the appeal to reason worked."
