Right now, wind supplies about one percent of US electricity.

The most welcome news all week? America could ramp that up to 20% by 2030 for an investment of just $43 billion, the DOE has found in a new eye-popping report.

What a bargain when you consider that the US will spend around $12 billion each month in Iraq in 2008.

For less than four months at that price, the nation could secure the future of its booming wind energy industry, help end its dependence on foreign oil and support a half a million jobs.

Clean coal isn’t having much luck.

The latest project casualty is a carbon capture and storage plant planned for Kwinana, Australia – south of Perth.

BP pulled the plug on the $2 billion venture on account of an unforeseen geological defect in the area: The leaky rock formations can’t seem to seal in CO2 for the long-term.

Last month, retail giant Tesco became the world’s first supermarket to stick carbon impact labels on its own-brand products.

Who's behind it all?

The UK's Carbon Trust, with its proprietary carbon-labeling scheme that it brought to market in 2007.

The ubiquitous "Carbon Trust" name has been bouncing around the Web for ages.

So who are they exactly -- and what else are they doing?

The murky future of South Dakota’s Big Stone II coal plant is getting even murkier.

In Minnesota, two administrative law judges have ruled against the building of the power lines that Big Stone II needs to run, overturning a recommendation they made last year.

Why? Because the five power companies trying to build it couldn’t justify the need for hundreds of new megawatts of the dirty fuel.

Not when the judges considered the rising costs -- the four million tons of CO2 pollution each year plus rate hikes for Minnesota customers after a federal price on carbon kicks in that forces coal polluters to pay.

The better bet for the state, say the judges? Renewable energy. Mainly wind, and efficiency measures.

Huge.
