Using an Easy-Bake Oven Is About to Become Difficult

The Easy-Bake Oven is falling victim to the fight against global warming. The incandescent light bulbs that heat the toy ovens are being phased out in 2012 in favor of energy-efficient compact fluorescents.

What U.S. Energy Policy Needs: Less Coal, More Uranium

In a political victory for Barack Obama, the U.S. president emerged from the global climate summit in Copenhagen late Friday with a deal with China, India and other key countries to reduce earth-harming emissions. But environmentalists were disappointed the cuts were not binding while skeptics weren't disappointed there was a deal at all.

Finding Common Ground
in Copenhagen?

As the world's leaders converge on Copenhagen for the global climate summit, the clouds over what had been deemed a fairly useless exercise in geopolitical stagecraft appeared to be lifting.
