Water On The Mind By Dakota Hoffman
One of the many benefits to Hydro electric power that is often taken for granted and overlooked is that it is not only the cleanest form of renewable energy but it is the most easily renewed
Because of the water cycle, hydro electric energy is always accesible at all times.
Hydropower is better for the environment than other major sources of electrical power, which use fossil fuels. Hydropower plants do not emit the waste heat and gases—common with fossil-fuel driven facilities—which are major contributors to air pollution, global warming and acid rain. The mining and drilling required to acquire fossil fuels for other power sources also have a significant negative environmental impact.
Using a dam, reservoir, turbines, generators, and penstocks (pipes), hydropower plants convert the energy in moving water to electricity. The height of the water fall (head) and the volume of flow determine the quantity of electricity generated. The higher the head and greater the volume, the more energy produced. Dams store the water that is channeled to the powerhouse where the water turns the turbines. After the generators produce electricity, it is transferred to an electrical power substation and used.
This is the Hoover Dam. , One of America's very few examples of an Arch Style Dam. The Arch Style Dam is efficient because it bends against the current of water and creates more pressure causing the water to generate more kinetic energy against turbines when released.
