Natural Resources
Solar Energy— energy from the sun • Solar cells can be mounted on roofs of buildings to produce electricity and heat energy.
Hydroelectric Power—energy from water • Machines inside of dams can change moving water into electrical energy. Wind Energy—Moving air can turn the blades of windmills. The windmills change the wind energy into electrical energy. Nuclear Energy—energy that is given off by splitting the nucleus of an atom (uranium) Geothermal Energy—energy from heat from melted rock deep below the Earth’s surface Biofuels—renewable energy made from biomass (crops, wood, trash, manure) |
