Non-renewable resource. Coal emissions are linked to global warming, acid rain, smog, and mercury contamination of water. Underground mining can be dangerous. Surface mining destroys large areas of the landscape. Advantages of Energy Use Disadvantages of Energy Use Plentiful in US. High energy content. Relatively inexpensive. Electrical Energy in the United States – Part 4 COAL
34
Advantages of Energy Use Disadvantages of Energy Use Electrical Energy in the United States – Part 4 PETROLEUM The most abundant and versatile energy resource. Liquid form makes it easy to transport and use. High energy content. Relatively inexpensive. Non-renewable resource. Oil emissions are linked to global warming and acid rain. Oil drilling endangers the environment. Oil transportation can lead to spills, causing environmental damage. Dependence on foreign sources.
35
Advantages of Energy Use Disadvantages of Energy Use Electrical Energy in the United States – Part 4 NATURAL GAS Burns clean and produces practically no harmful by-products. High energy content. Relatively inexpensive. Non-renewable resource. Combustibility. Fracking can contaminate drinking water and contribute to air pollution.
