Ways that energy is wasted:
About 70% of energy is discarded as excess heat in coal-fired power plants in the US
Electronics take up way too much electricity when they're off
Good insulation can let a house with surroundings at about 40 degrees C go comfortably without a heater
All this excess heat made by stuff could be put to use
Cars are very wasteful. They could be 3 times as efficient if their weight was cut in half
Bush is not investing much into renewable energy and efficiency
