3. Kinetic energy is the energy of motion. Any moving object has kinetic energy.

4. Humans first learned to harness the kinetic energy in water by using waterwheels. A waterwheel is a revolving wheel fitted with blades, buckets, or vanes. Waterwheels convert the kinetic energy of flowing water to mechanical energy. This later gave the idea of Hydro-power.

5. What Is Hydro- electricity? Hydro electricity is the term referring to electricity generated by hydro power ; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the carbon dioxide (CO 2 ) than fossil fuel powered energy plants.

6. History Of Hydro- electricity. Hydro power has been used since ancient times to grind flour and perform others tasks. In the mid-1770s, a French engineer Bernard Forest de Belabor published Architecture Hydraulique which described vertical- and horizontal-axis hydraulic machines. In the late 1800s, the electrical generator was developed and could now be coupled with hydraulics. The growing demand for the Industrial Revolution would drive development as well. In 1878, the world's first house to be powered with hydroelectricity was Cragside in Norththumberland England. The old Schoelkopf power station No 1 near Niagara falls in the U.S. side began to produce electricity in 1881.
