The United States Currently Relies Heavily On Coal, Oil, And Natural Gas For Its Energy. Fossil Fuels Are Non-Renewable, That Is, They Draw On Finite Resources That Will Eventually Dwindle, Becoming Too Expensive Or Too Environmentally Damaging To Retrieve. In Contrast, The Many Types Of Renewable Energy Resources-Such As Wind And Solar Energy-Are Constantly Replenished And Will Never Run Out.

Most Renewable Energy Comes Either Directly Or Indirectly From The Sun. Sunlight, Or Solar Energy, Can Be Used Directly For Heating And Lighting Homes And Other Buildings, For Generating Electricity, And For Hot Water Heating, Solar Cooling, And A Variety Of Commercial And Industrial Uses.

The Sun’s Heat Also Drives The Winds, Whose Energy, Is Captured With Wind Turbines. Then, The Winds And The Sun’s Heat Cause Water To Evaporate. When This Water Vapor Turns Into Rain Or Snow And Flows Downhill Into Rivers Or Streams, Its Energy Can Be Captured Using ​
