Re-write the paragraph below. It contains comma splices, run-ons, and sentence fragments. Americans use more energy per person than any other people in the world. We have only 6 percent of the world’s population but we use about one-third of all the energy consumed on this globe. Our total national energy cost in 1975 amounted to about $170 billion, each year our energy needs are steadily rising. Most of the energy we use in the U. S. comes from crude oil domestic production falls short of our needs, we have to import almost half of it. Expert estimates of our known and potential domestic reserves vary, we probably have somewhere between a 25- to 30-year supply of oil. We must, though, keep our energy-use growth to about 2 percent per year. If we continue using energy as we have become accustomed to. We could run out of domestic oil supplies in the year 2007, we may run out of natural gas even sooner. The overall energy situation in the U. S. is not rosy. Energy demands and prices keep going up, therefore, the availability and future costs of supplies remain uncertain.
