Another great renewable energy source that is as timely as the sun is wind. Wind turbines are built with large blades and a rudder to catch the wind as it blows, thus turning the large blades, which then charges up batteries and other energy storing devices. Though the sun is always present, wind sometimes is picky about when it blows, but when it does, the amount of energy that is converted is amazing. The stored energy from the wind used to power companies and homes just the same as the sun, and when used in tangent with the solar panels, the amounts of stored energy is more than enough to run large businesses and homes. With using wind energy, it will also reduce the cost of the electric bills and therefore take less energy for the power companies to need to use to power large city blocks or rural communities. Wind energy is a renewable energy source that will never lose its value and because of that, it will always remain, along with solar power, as sources to harness.
