There are three different types of hydroelectric energy plants, the most common being an impoundment facility. In an impoundment facility, a dam is used to
The power plant is the location in which the energy conversions take place. Traditionally, large power plants have been located in sub-urban regions away from cities, as they need a vast area of land and sometimes water. All electricity produced in a power plant is alternating current (AC). The type of electric current found in your home is
Rated Capacity Unit of electric power equal to 1,000 watts or about 1.34 horsepower. For example, it''s the amount of electric energy required to light ten 100-watt light bulbs. The unit of electrical energy commonly used in marketing electric power; the energy produced by 1 kilowatt acting for one hour.
A power plant is an industrial facility used to generate electric power with the help of one or more generators which converts different energy sources into electric power. Electricity is a secondary energy source, which means that electricity is obtained from the conversion of other primary sources of energy, such as coal, natural gas, nuclear, solar, or wind energy.

5 · Hydroelectric energy is made by moving water. Hydro comes from the Greek word for water. Hydroelectric energy has been in use for thousands of years. Ancient Romans built turbines, which are wheels turned by flowing water. Roman turbines were not used for electricity, but for grinding grains to make flour and breads.
The three main types of geothermal plants include dry steam power stations, flash steam power stations and binary cycle power stations, all of which use steam turbines to produce electricity. The installed capacity of geothermal energy has gradually increased worldwide over the past decade, up from just short of 10 GW in 2010 to almost
