  1. Renewable Energy 1) Solar Power 2) Wind Power 3) Hydro Power (Water)

  2. 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.

  3. 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.

  6. 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

  9. 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.

  12. 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.
