Waterpower, power derived from the fall of peeing from a higher to a lower level, and extracted by means of waterwheels or hydraulic turbines. Waterpower is a natural resource, available wherever a sufficient batch of steady water flow exists. The reading of waterpower today requires big construction, including storage lakes; dams, bypass canals, and the installation of large turbines and electric generating equipment. Because the development of hydroelectric power requires a large capital investment, it is practically uneconomical for a region where coal or oil colour is cheap, even though the cost of fuel for a powered generating plant is higher than the cost of running a hydroelectric plant. However, increasing environmental concerns are focusing attention on renewable energy sources such as water.
GEOTHERMAL ENERGY
geothermic Energy, energy contained in intense heat that continually flows outward-bound from deep within Earth. This heat originates primarily in the core. nigh heat is generated in the crust, the planets outer layer, by the decay of radioactive elements that are in all rocks. The crust, which is almost 5 to 75 km (about 3 to 47 mi) thick, insulates the muster up from the intent interior, which at the core may reach temperatures from 4000° to 7000° C (7200° to 12,600° F).
Where the heat is concentrated near the surface, it can be utilise as a source of energy.
In certain areas, water seeping down through cracks and fissures in the crust comes in contact with this hot rock and is heated to high temperatures. about of this heated water circulates back to the surface and appears as hot springs and geysers. However, the rising hot water may remain hole-and-corner(a) in areas of permeable hot rock, forming geothermal reservoirs. Geothermal reservoirs, which may reach temperatures of more than 350° C (700° F), can provide a powerful source of energy.
