Google writes about Energy Efficiency
With the days getting shorter and the temperature dropping, it's the perfect season to talk about energy efficiency. And quite fittingly, many of the energy-wasters in the homes are named after the ghouls of Halloween. Living rooms are infested with "vampire" electronics that suck power even when turned off; open chimney flues let the "ghosts" of winter steal our heat; and quite often there's a "monster" furnace lurking in the basement. By taking small steps to drive out the goblins of inefficiency, you can save money and ward off carbon emissions. So Google created a handy energy saving calculator and a list of tricks to help you do just that.
