Renewable energy sources are energy sources that are continually replenished. These include energy from water, wind, the sun, geothermal sources, and biomass sources such as energy crops. In contrast, fuels such as coal, oil, and natural gas are non- renewable. Once a deposit of these fuels is depleted it cannot be replenished, a replacement must be found instead. Both renewable and non-renewable energy sources are used to generate electricity, power vehicles, and provide heating, cooling, and light. There are five main renewable energies being used in the United States now, we cannot expect one type of energy source to supply all our energy needs. Based on geography and the effect that these energy sources have on the natural environment around them, it is impossible to install only one renewable energy source. There needs to be a collaboration of the most cost-efficient and highest energy producing sources. In my opinion hydropower, solar power and wind power seem to be the most effective. Hydropower is the use of water to generate electricity. Dams are built on a river to store water. Water is released from behind the dam and flows through a turbine, spinning it, which then turns a generator, producing energy. Today hydroelectricity accounts for 7% of the electricity used by the nation. Hydropower has some geographical limitations because of the availability of rivers. I think that is it important to install dams in the rivers that are available and that make sense for the nation. The upside to this is that hydropower does not always have to be a big dam. Some hydroelectric power plants use a small canal to channel the river water through a turbine. A small or micro-hydroelectric power system can produce enough electricity for a home

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
