Energy is very important in our modern life. People use energy (1)to transportation, cooking, heating and cooling rooms, manufacturing, lighting, and entertainment. (2)Most energy nowadays comes from fossil fuels – petroleum, coal, and natural gas. (3)However , burning fossil fuels causes pollution. Also, if we don’t find new kinds of energy, we will (4)use up all the fossil fuels in the near future.
