We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
Energy does things for us. It moves cars along the road and boats on the. water. It bakes a cake in the oven and keeps ice frozen in the freezer. It. plays our favorite songs and lights our homes at night so that we can. read good books. Energy helps our bodies grow and our minds think.
