The modern marvel that is the wind turbine is doing amazing things to produce clean energy. Since as far back as 200 B.C., windmills have been used to grind grain or draw water, but electricity didn't start being produced until 1888. Those first turbines aren't as efficient as the ones we are deploying all over the world today, but it is great to look back on where we started from.
Today, wind power systems generate power for schools, buildings, homes and so much more. Take a look at what makes these massive windmills work and see how the energy is produced in this great graphic below:
