Renewable Energy : Alternative Energy

Alternative energy can be defined as Energy, as solar, wind, or nuclear energy, that can replace or supplement traditional fossil-fuel sources, such as coal, oil, and natural gas. When thinking about alternative energy sources we generally focus on the main types: nuclear, solar, wind, and hydroelectric. These are things that mainly do not cause pollution and are very environmentally friendly (Alternative Energy). Alternative energy is thought to be renewable and “free.” Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy all have very low carbon emissions compared to the conventional energy sources (Alternative Energy). With using the alternative energy route instead of conventional energy sources, we can help to keep this earth going for a very long time. So how are all of these things generated? Nuclear energy is fueled from a power plant, much like fossil fuels. To start, water is first turned into steam which helps to produce electricity. The heat that is used to make the steam out of the water is what makes the uranium atoms split; this is called fission. Here in the United States we have two types of nuclear reactors, Pressurized Water Reactor and Boiling Water Reactor. The first type is to help keep the water under a lot of pressure to make it heat up, but does not allow it to boil. The water then travels though a number of tubes that the water can steam up in which helps to turn the turbine generators. The second type of water
