An example of a renewable energy source that I examined was wind energy, which creates electricity by using the wind, and air flows that occur naturally in Earth’s atmosphere. With the creation of wind turbines, we were able to capture kinetic energy that was created by the wind and generate electricity. There are three distinct types of wind energy: Utility-scale wind are wind turbines that range in size from one hundred kilowatts to megawatts. The electricity is delivered to the power grid and then distributed to the end user by electric utilities or power system operators. Distributed or “small” wind single small wind turbines that are below 100 kilowatts and are used to directly power a home, farm or small business and are not connected to the grid. And the third type is generated by Offshore Wind, these turbines that are erected in large bodies of water, usually on the continental shelf. Offshore wind turbines are larger than land-based turbines and can generate more power.
The turbines typically stand a little over 260 feet high and wind measurements are collected, and they direct the turbine to rotate while facing the strongest wind, at the correct angle of its blades to capture energy. Over the course of a year, turbines can generate enough usable electricity over 90 percent of the time. These turbines begin to generate power when the wind reaches six to nine miles per hour and will shut down if the wind reaches over fifty-five miles per hour to avoid damages. The building and maintaining of these wind turbines can provide new jobs and begin the spread of “wind farms”.
