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

 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.

 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.
