| alternative resources | any renewable and inexhaustible sources of energy to generate electricity, including solar energy, wind, and geothermal energy |
| chemical energy | energy that is stored in chemicals |
| electrical energy | energy carried by electric current that comes out of batteries and wall sockets, is generated at large power plants, and is readily transformed into other types of energy |
| energy | the ability to cause change |
| generator | device that transforms kinetic energy into electrical energy |
| inexhaustible resources | source of energy which cannot be used up by humans |
| kinetic energy | energy an object has due to its motion |
| law of conservation of energy | states that energy can change its form but it is never created or destroyed |
| nonrenewable resource | any energy sources that eventually will run out such as coal, and oil |
| nuclear energy | energy stored in atomic nuclei that can be transformed into other forms of energy by complex power plants |
| photovoltaic | device that transform radiant energy directly into electrical energy |
| potential energy | energy stored in an object due to its position |
| radiant energy | energy of light |
| renewable resources | any energy sources that are replenished continually |
| thermal energy | energy that all objects have; increases as the object's temperature increases |
| turbine | set of steam-powered fan blades that spin a generator at a power plant |
