AMS SOL 6.2 part 2
| 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 |
| wind turbine | uses the mechanical energy of wind to generate electricity |
| advantages of wind power | clean and renewable |
| disadvantages of wind power | turbines are expensive to build, noisey, and dangerous to birds |
| geothermal | heat energy from inside the Earth |
| Ring of Fire | edge of the Pacific Ocean where geothermal heat is abundant |
| Geothermal Reservoir | underground pool of hot water or steam |
| Advantages of geothermal | clean and renewable |
| disadvantages of geothermal | very limited availability |
| solar power | using heat and light energy from the sun to generate electricity |
| photovoltaic cells | solar panels which convert sunlight into electricity |
| parabolic trough | curved mirror used to focus sunlight onto a pipe filled with water in order to make steam |
| batteries | used to store energy at a solar power plant for use when the sun it not shining |
| advantages of solar power | clean and renewable |
| disadvantages of solar power | panels are expensive, sun doesn't shine at night |
| biomass power | using the chemical energy stored in living material to generate electricity |
| advantages of biomass | renewable and easy to find, can be built anywhere |
| disadvantages of biomass | burning causes air pollution |
