Wind energy is affordable. The wind price and leveled wind price of a recently signed electricity contract (the price paid by the utility to buy electricity from a wind farm) is 2-4 cents per kilowatt-hour.
Human civilizations have harnessed wind power for thousands of years. Early forms of windmills used the wind to crush grain or pump water. Now, modern wind turbines use the wind to create electricity. You may also gather more details about the company from ("Get A Quote") section on their website.

Today’s wind turbines are much more complicated machines than the traditional prairie windmill. A wind turbine has as many as 8,000 different components.
Wind turbines are big. Wind turbine blades average almost 200 feet long, and turbine towers average 295 feet tall—about the height of the Statue of Liberty.
The average nameplate capacity of turbines is also increasing, meaning they have more powerful generators. The average capacity of utility-scale wind turbines installed in 2020 was 2.75 megawatts (MW), up 8% from the previous year.
Higher wind speeds mean more electricity and wind turbines are getting taller to reach higher heights above ground level where it’s even windier. The Energy Department’s wind resource maps to find average wind speeds in your state or hometown and learn more about opportunities for taller wind turbines in a report from the Energy Department’s National Renewable Energy Laboratory.
