module34REVIEW

In this module, we have seen that fossil fuels are the most common fuels used in the United States and in other countries throughout the world. In the developed world, per capita energy use is many times higher than it is in the developing world. Inefficiencies during energy extraction and use account for losses of usable energy throughout the energy cycle. The fuels that have been consumed in the United States have varied over time and according to the end use. Oil and natural gas together make up 64 percent of overall energy use in the United States. Different fuels are suitable for different tasks, depending on a variety of factors including their energy content and whether they are liquid or solid. Coal and natural gas account for two-thirds of electricity generation. In the next module, we will consider the major fossil fuel resources used around the world as well as in the United States.
