Online shopping
Additionally, widespread use of the Internet by businesses and corporations drives down energy costs. Besides the fact that Internet usage does not consume large amounts of energy, businesses who utilize connections no longer have to ship, stock, heat, cool, and light unsellable items whose lack of consumption not only yields less profit for the company but also wastes more energy. Online shopping contributes to less fuel use: a 10-pound package via airmail uses 40% less fuel than a trip to buy that same package at a local mall, or shipping via railroad. Researchers in 2000 predicted a continuing decline in energy due to Internet consumption to save 2.7 million tons of paper per year, yielding a decrease by 10 million tons of carbon dioxide global warming pollution per year.
