    We can generate hydroelectricity when rain water collected in a reservoir (or water in a pumped storage scheme) flows downhill. The flowing water drives turbines that turn electricity generators at the foot of the hill. A Hydroelectricity system is used all day and all night. At night they use leftover electricity to pump water back up to use again the next day Hydroelectric energy is inexpensive. In the US‚ it costs an average of 0.7 cents (which is about 43p) per kilowatt-hour (kWh) to produce

    Hydroelectricity or hydroelectric power is the electricity obtained by harnessing the power of water flowing down from a high level. It is a timeless and renewable resource.  Huge generators  convert the potential energy of falling or fast moving water into electrical energy. The potential energy of the water is first converted into mechanical energy and then into electrical energy. Water‚ usually stored in dams‚ is led down through large pipes or tunnels to lower levels‚ and in the course

    What is Hydroelectricity? Hydroelectricity‚ in the simplest of terms‚ is the electricity that is generated using flowing water‚ or that water which is stored in a reservoir. In both cases however‚ the basic fundamental principle of power generation remains the same. here is an explanation of how hydroelectricity is generated. A large volume of water is stored in a reservoir at a high altitude. A power generation plant‚ consisting of multiple turbines is constructed downstream‚ at a much lower

    decided to re-express the variables in the hope of making the distribution of a variable more symmetric and make the residual plot more spread out evenly. We did this by testing hydroelectricity vs. LogWind‚ LogHydroelctricity vs. LogWind‚ and LogHyrdroelectricity vs. Wind. The first one that we tested was hydroelectricity vs. LogWind which gave us a regression equation of hydroelectric conventional = -9732703 + 1285448
