Generation of Electricity by Both Mega Hydro and Tidal Power Systems

Abstract

Electricity is now an important part of homes and industries. Almost all the devices at homes, businesses and industries are running because of electricity. Mega hydro is hydro power with a maximum electrical output. Hydro power or water power is power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes. Hydropower is fuelled by water, so it is a clean fuel source. Hydro power systems of this size benefit in terms of cost and simplicity from different approaches in the design, planning and installation than those which are applied to larger hydro power. Tidal energy is one of the sources of ocean energy. Tide is a periodic rise and fall of the water level of sea which are carried by the action of the sun and moon on the water of earth. Tides are produced mainly by the gravitational attraction of the moon and the sun on the water of solid earth and the oceans. About the 70% of the tide producing force is due to the moon and 30% due to the sun. A tidal generator converts the energy of tidal flows into electricity. Greater tidal variation and higher tidal current velocities can dramatically increase the potential of a site for tidal electricity generation. Tidal power or tidal energy is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation.
