| nuclear energy | energy released by nuclear reactions; can be considered as both renewable & non-renewable energy source |
| energy conversation | reducing energy use |
| alternative energy resources | energy resources derived from a natural source, such as the sun, wind, tides, or waves; also called renewable energy resources |
