4. Benefits of Wind Turbines • Countries like the United States use wind turbines for clean energy. They also power thousands of building in the country. • Wind turbines work best in places with a lot of wind such as near an Ocean.

5. Cost of Wind Turbines • Big turbines are usually between $1.3-$2.2 million. • Small turbines that can be used to power a large house cost between $50,000-$90,000. (or more)

6. Advantage of Wind Turbines • Wind turbines provide clean energy that doesn’t give off green house gases and other pollutants.

8. Advantage of Wind Turbines • The wind is free and with modern technology it can be captured efficiently.

9. Disadvantage of Wind Turbines • Kills many birds.

10. Disadvantage of Wind Turbines • The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.

11. Disadvantage of Wind Turbines • Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.

12. Wind Turbines in Texarkana Texarkana shouldn’t use wind turbines because… • It would cost too much money to power the whole city. • Each turbine costs over 1 million dollars. • It would kill many birds that fly through Texarkana • Not enough wind to work efficiently
