We don’t think about energy when it comes to computers. Yea it gets warm especially those laptops. But energy is a big concern for computer makers because where there is energy there is heat and heat is not good. In the last year nanotechnology has made it possible to create parts of computers that are about 45 nanometers. That means that about 2000 would fit across the width of a hair. Not only are they making these computer chips with smaller parts but they are consuming less energy? How much? If you figure how much progress has been made in computer chips and figure the same amount of progress in cars—-your car would get 100,000 miles to the gallon. That is about four times around the world on a gallon of gas. (from Intel)
