What are 3 renewable sources of energy and an example of each?
Wind turbines take the mechanical energy of wind to generate electricity. Solar cells and solar collectors take the electromagnetic energy in sunlight to generate electrical energy or generate thermal energy to heat a substance. Hydroelectric facilities use the power of water under the influence of gravity to generate mechanical energy and (often) electric power. Let’s throw in the idea that if we plumb (put pipes into) volcanic or thermal vents, we can collect thermal energy from the core of the earth. This can be used directly to heat things or to generate mechanical energy to create electricity.
