In other technology-that’s-not-actually-going-to-save-us news, China's building a $1.5 billion clean coal plant, the first commercial clean coal plant of this size.

European countries are ditching even the tiniest of cars in favor of public transportation, because — surprise! — global treaties matter and EU countries need to cut carbon in some way to meet their Kyoto commitments.
