All of us use energy every day for entertainment, cooking, transportation, lighting, heating and cooling homes, manufacturing, etc. We consume a lot of energy. The United States consumes about one fourth of the world's energy resources.
When energy is produced from non-renewable fuels, to heat our homes or power our cars for example, pollutants are released into the air contaminating the air we breathe and water too. The more energy we use or miles we drive in our cars, the more energy power plants must produce or gasoline our cars burn, releasing more pollutants into the air
