Renewable Resources and Hydropower

Ending pollution caused by fossil fuels would be only one of the greater benefits to using renewable resources. .
             One kind of renewable resource that is widely used is hydroelectric energy. Hydroelectric energy refers to electricity created by something hydropower. This is the generation of electrical energy through the conventional use of the force of falling or flowing water. Hydropower is one of the most widely used forms of renewable energy. A reason for this is that, out of all the renewable energy forms, this has the lowest cost per watt hour. Another reason is it has a consistent all year round power output.
             Most hydroelectric energy is generated from potential energy of dammed water propelling a turbine to generate electricity. While this is the most common form, there are other variations of hydroelectric energy. For example, some use the kinetic energy of free-flowing water and waterfalls. Strictly speaking, hydroelectric power is somewhat of a combination between solar and gravitational energy. The sun's solar energy causes evaporation to occur and forces water vapor to rise to higher elevations, which then condensates and gives water gravitational potential energy that makes it fall from higher elevations.
             There are many advantages to switching to hydropower. We essentially have an unlimited source of water, so finding locations wouldn't be a problem. Dams that generate hydropower don't add to the pollution which is a major plus. It is also a source that is very reliable. The weather and the climate wouldn't really have any effect on the energy output created by these dams. .
             Also, hydropower is generally available when needed. Engineers can control the course of flowing water through turbines to produce electricity on demand. Plants that use hydropower provide additional benefits besides clean electricity. The usage of hydropower creates reservoirs that offer recreational opportunities; especially boating, fishing, and swimming.
