4. History Combining windmills together allowed for effective flood control. Combining windmills together allowed for effective flood control.

5. How It Works Wind spins rotor. Wind spins rotor. Rotor spins low- speed shaft through gearbox. Rotor spins low- speed shaft through gearbox. Gears spin high- speed shaft through generator. Gears spin high- speed shaft through generator.

6. Applications Many countries use land based and offshore wind farms to generate power. Many countries use land based and offshore wind farms to generate power. The U.S., Germany, and Spain are the three global leaders in wind power generation and consumption. The U.S., Germany, and Spain are the three global leaders in wind power generation and consumption.

7. Applications Small scale wind power can be used to power individual homes or even small communities. Small scale wind power can be used to power individual homes or even small communities. While power is not being used, the wind turbine can charge batteries for power storage. While power is not being used, the wind turbine can charge batteries for power storage. This can reduce or even eliminate the dependence on grid power consumption. This can reduce or even eliminate the dependence on grid power consumption.

8. Future Stanford scientists believe that there are 72 TW of wind power available on land or near-shore. That’s equivalent to 54,000 megatons of oil per year. Stanford scientists believe that there are 72 TW of wind power available on land or near-shore. That’s equivalent to 54,000 megatons of oil per year. That is more than 5 times the world energy consumption in all forms. That is more than 5 times the world energy consumption in all forms. Marginal cost of wind energy once the plant is built is less than 1 cent per kilowatt-hour. Marginal cost of wind energy once the plant is built is less than 1 cent per kilowatt-hour.
