Summary 1: Energy Resources

People uses energy everyday for lighting their homes, cook food, to move from one place to another.  Usually the source of our energy we use are coal, natural gas and oil.  These source of energy are called natural resources and they are limited so one day we will run out of them if we do not conserve energy. Nowdays people are experimenting with alternative energy such as geothemal energy, solar, wind and biomass to contribute in the conservation of our natural resources and energy supply.
