According to a new report released today by the American Council for an Energy-Efficient Economy, or ACEE , Americans could eliminate 158 million tons of greenhouse gas per year by 2030 – that's the equivalent of shutting down 63 large coal-fired power plants – and $123 billion, by changing the way some of our most common household appliances work.

This is old news to many of the folks at California Energy Commission , who have pushed for such changes for decades. But the real news is that these aren't just recommendations anymore. They're policy, or soon will be.

According to the ACEE, the Obama Administration plans to revamp 23 common household products – everything from battery chargers and clothes dryers to air conditioners – by requiring that manufacturers make more energy-efficient models. The ACEE report (no doubt intended to put a little wind into the White House's sails) adds to the story by calculating just what a difference those changes would collectively make.
