The Climate Post: Read this. Read now. Pay nothing.
First things first: The Obama administration today finalized greenhouse gas emissions standards for cars and light trucks first proposed last May. The practical upshot of the rules is a roughly 40 percent rise in fuel economy, to 35.5 miles per gallon, by 2016. The government said the measures would save owners about $3,000 in fuel […]

Challenging conventional wisdom on renewable energy’s limits
In making the case for a rapid conversion away from heavily polluting energy sources like coal and nuclear power to cleaner generation, renewable energy advocates often confront the argument that their scheme is impossible due to the intermittent nature of sun and wind.

Community solar gardens
A new bill being considered in the Colorado legislature would create “solar gardens.” Solar gardens allow people to participate financially in owning part of a solar array even if they do not have a suitable site on their own property. My reading of the proposed legislation is that subscriptions in a solar garden would be […]

Arizona introduces bill to redefine renewable standard to include nukes
In Arizona, a new bill has been introduced that would kill renewable energy progress in the state. HB 2701 would establish a legislative version of the Arizona Corporation Commission’s regulatorily-implemented Renewable Energy Standard of 15% by 2020, but with some tragic differences. For one, the bill would redefine renewables to include large hydro and nuclear. […]
