Renewable Energy 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.

Solar Power “Solar” is the Latin word for “sun” – and it’s a powerful source of energy. In fact, the sunlight that shines on the Earth in just one hour could meet world energy demand for an entire year! We can use solar power in two different ways: as a heat source, and as an energy source. “Solar” is the Latin word for “sun” – and it’s a powerful source of energy.

Wind Power Using the wind to create electricity has been around for a long time - you've probably seen windmills on farms. When the wind turns the blades of a windmill, it spins a turbine inside a small generator to produce electricity. A windmill on a farm can make only a small amount of electricity - enough to power a few farm machines. To make enough electricity to serve lots of people, power companies build "wind farms" with dozens of huge wind turbines Using the wind to create electricity has been around for a long time - you've probably seen windmills on farms.

Hydro Power “Hydro” means “water” in Latin - so hydro power is made from water. It might sound odd that we can use water to make electricity - they're a dangerous combination, right? Actually, the water never comes in contact with the electricity. The water flowing down a river is used to spin the turbines inside the generator. “Hydro” means “water” in Latin - so hydro power is made from water.

Questions and Activity Question: What are three forms of renewable energy? Question: How could your community use a form of renewable energy? Activity: Create a community (urban, suburban or rural) that uses one of these forms of energy. Question: What are three forms of renewable energy?
