Future Wind Power
Have you ever wondered how much of the energy you use comes from wind power?
Can the growth of the number of wind farms in the United States be modeled by a linear function? Can you determine how much wind power will be needed in the future?
1. In 2012, the United States generated approximately 3.5% of its electricity from wind power. Approximately 4 billion kilowatt hours (kWh) of electricity was used.
a. A terawatt hour (TWh) is equal to 1,000,000,000 kilowatt hours. How many terawatt hours is equal to 4 trillion kilowatt hours? 4000
4000X1,000,000,000
b. How much of the electricity in 2012 came from wind power? Write your answer in terawatt hours.
3.5% came from wind power = 140(TWh)
c. You will be writing an equation which represents wind farm growth since 2012. What ordered pair can you use as your initial value?
