I’ll begin with Wind, which utilizes a Wind Turbine or more commonly known as windmill. 1. Modern wind turbines are used to generate electricity. 2. Wind turbines convert the kinetic energy of moving wind. 3. A wind turbine works like a fan, but in reverse. 4. Also a collection of wind turbines is called a wind farm. B. Next up we have the power of the Sun, Solar energy. It is certainly the oldest type of alternative energy used. . Photovoltaic (PV) is the most common solar collector used today; an example is the panels people put on rooftops or vending machines. 6. It produces electricity from the energy of the sun. 7. Energy of the absorbed light is transferred to electrons of the PV cell. C. Rivers are the source of another popular technology. Hydroelectric Turbines leverage this hydro energy. 8. Hydroelectric Turbines are powered by the kinetic energy of the flowing water. 9. Water flows through a turbine and generators convert the energy into electricity. 10.

It’s like a water pump but in reverse order, much like the wind turbine. Transition: Now that you know a few of the options. You may want to know what the benefits are. III.

Currently 24 states offer Tax credits with more to be added in the future. 18. Not to mention there are numerous federal grant programs that will help you to utilize some source of alternative energy. Today I’ve given you the primary types of alternative and earth friendly energy sources.

I hope that you take the information I’ve given you to further obtain knowledge on at least one of these sources of alternative energy. I have also given you the benefits of using alternative energy and I hope the thought of a healthier and cleaner earth will be motivation to help progress the use of alternative energy.
