We learned how each renewable energy source is used to form electricity.
Wind...
Like the propeller blades of an airplane, wind turbine blades use the moving air to power an electric generator that supplies an electric current.
Biomass...
Power companies are also working with customers to find new ways to make electricity, from crops like switchgrass and even from cow poop!
Solar...
Have you ever used a magnifying glass to make something melt or burn? If yes, than you were using solar power!
Hydro...
Hydro means "water" in Greek - so "hydro power" is energy made from water.
Geothermal...
Have you ever seen pictures of a volcano or a geyser? If so, then you've seen geothermal energy in action!
