power, but that number is expected to increase in the future (Frater, “Top 10 Renewable Energy Sources”). Wind power turbines that are placed in large open areas have the least environmental impact. An example of a wind power farm would be the San Gorgonio Pass Wind Farm in Riverside County, California. Geothermal energy and biomass are the next two efficient renewable energy sources. Scientists generate geothermal energy by digging beneath the earth’s crust and using that heat to produce energy. This
