Document Summary

Chapter 15 fossil fuels: energy and impacts. A great deal of energy emanates from earth s core, making geothermal power available for our use. Most of our energy, however, comes from the sun. The three fossil fuels we use widely today are oil, coal, and natural gas. Since the industrial revolution, fossil fuels have replaced biomass as our society s dominant source of energy. Besides providing for transportation, heating, and cooking, these fuels are used to generate electricity, a secondary form of energy that is easier to transfer over long distances and apply to a variety of uses. Fossil fuels are indeed fuels created from fossils . Most organisms, after death, do not end up as part of a coal, gas, or oil deposit. Fossil fuels are produced only when organic material is broken down in an anaerobic environment, one that has little or no oxygen. Such environments include the bottoms of shallow seas, deep lakes, and swamps.
