Energy is produced to generate electricity and to keep us warm. Most energy is produced by the burning of fossil fuels, like coal, oil and gas, which release carbon dioxide, a greenhouse gas. Fuel burnt in our cars also releases carbon dioxide. As an individual, you do not have a lot of control on how your energy is produced. However, you can control the way in which you use that energy. Using less energy means l
less of it needs to be produced. So less carbon dioxide is released into the atmosphere.
