While cars becoming more efficient, gadgets guzzle more and more electricity, with flat screen TV's the worst offenders

The biggest offender is the flat-screen television.

Worldwide, consumer electronics now represent 15 percent of household power demand, and that is expected to triple over the next two decades, according to the International Energy Agency, making it more difficult to tackle the greenhouse gas emissions responsible for global warming.

To satisfy the demand from gadgets will require building the equivalent of 560 coal-fired power plants, or 230 nuclear plants, according to the agency.

The proliferation of personal computers, iPods, cellphones, game consoles and all the rest amounts to the fastest-growing source of power demand in the world. Americans now have about 25 consumer electronic products in every household, compared with just three in 1980.
