Question | Answer |
generator | a piece of equipment used at power plants to convert mechanical energy to electricity |
renewable energy | will not run out or can be replaced in a short amount of time |
nonrenewable energy | cannot be replaced and may run out |
fossil fuels | coal, oil, and natural gas which contain chemical energy |
advantages of fossil fuels | inexpensive, well understood, can be built anywhere |
disadvantages of fossil fuels | causes air pollution from too much Carbon Dioxide |
effects of air pollution | smog, breathing problems, global warming, acid rain |
nuclear power | using the energy stored in the nucleus of atoms to generate electricity |
Uranium | an element that is used as a fuel at nuclear power plants |
fission | splitting atoms |
radioactive waste | causes serious harm to humans and animals including cancer, birth defects, and death |
advantages of nuclear | does not create air pollution and is very efficient |
disadvantages of nuclear | radioactive waste and the possibility of an explosion |
hydroelectric power | using the mechanical energy of moving water to generate electricity |
advantages of hydroelectric | clean and inexpensive once built |
disadvantages of hydroelectric | flooding, blocks fish, and is not available everywhere |
