SOLAR ENERGY

Solar energy, derived from the sun's rays, can be converted into heat and electricity. It can be used to heat water and spaces, as well as generate electricity using solar panels. Solar energy is a renewable resource that is available all around the world. Explore the benefits and applications of solar energy.

  1. SOLAR ENERGY

  2. The sun has produced energy for billions of years. Solar energy is the sun’s rays that reach the Earth. This energy can be turned into other forms of energy like heat and electricity! http://www.eia.gov/kids/energy.cfm?page=solar_home-basics

  3. Solar Energy can be used to… • Heat water — for use in homes, buildings, or swimming pools • Heat spaces — inside homes, greenhouses, and other buildings • Heat fluids — to high temperatures to operate a turbine to generate electricity http://www.eia.gov/kids/energy.cfm?page=solar_home-basics

  5. The solar panels are made with something called silicon. When the sun’s rays hit the panels, the electrons inside begin to move around and it gives us electricity! Disadvantage: Solar panels are expensive because of what they are made out of. http://www.solarenergy.org/answers-younger-kids#5

  6. World Map of Solar Resources Some of the hottest places are near the equator because the sun shines directly on it. The equator is an imaginary line that wraps around the widest part of the earth. http://www.eia.gov/kids/energy.cfm?page=solar_home-basics

  7. Benefits of Solar Energy… • Solar energy does not produce toxins that make the air bad • Renewable resource- the sun is free energy • It is available all around the world
