Renewable energy is made from resources that Mother Nature will replace, like wind, water and sunshine. Renewable energy is also called "clean energy" or "green power" because it doesn't pollute the air or the water. Instead of using electricity to make wind, a wind turbine is used to make electricity. Biomass energy uses natural materials like trees and plants to make electricity. It can also mean waste products like trash. A hydro power plant in Wisconsin has been making electricity for almost 100 years. The sunlight that shines on the Earth in just one hour could meet world energy demand for an entire year. The hot lava from a volcano and the hot steam from a geyser both come from underground heat - and we can use that same type of heat in our homes.
