Ocean Thermal Energy Ocean develops the two types of energy : Thermal energy from the sun’s heat and Mechanical energy from tides and waves Ocean covers more than 70% of Earth’s surface making them the worlds largest solar collector. The sun’s heat warms the surface water a lot more than the deep ocean water and … Read more
Geothermal Power Generation Geothermal energy is the energy which lies embedded within the earth. Geothermal electric power plants are built on the edges of tectonic plates where high temperature geothermal resources are available near the surfaces. From the center of the earth, there are different zones such as solid metallic core A molten core A … Read more
Tidal energy power generation Tidal energy is the permanent source of energy. The rise and fall of tides nearly twice a day are associated with the rotation of earth every 24 hours in relation to both sun and moon. The tide amplitude may be considerable 18 to 21m have been noted near the Magellan strait … Read more
Wind Energy Electricity Generation Wind is mainly caused due to the solar heating of the atmosphere. Wind as a source of energy is very attractive because it is plentiful, inexhaustible, renewable , and non-pollutant. Wind blows for 320 days in a year and gives an advantage over sunlight. Worldwide five nations Germany, USA, Denmark, Spain … Read more
Photovoltaic or Solar cells Definition: The solar cell is a transducer or semiconductor which converts the suns radiant energy directly into electrical energy and is basically a semiconductor diode capable of developing a voltage of 0.5-1 volt and a current density of 20-40 mA/cm^2 depending upon the the material used and the conditions of sunlight. … Read more
Tariff Tariff means the schedule of rates or charges. The rate at which electrical energy is supplied to a consumer is known as tariff .Although tariff should include the total cost of producing and supplying electrical energy plus the profit but it cannot be same for all the types of consumers. Tariff is different for … Read more
Economics of Power Generation The generating stations may be steam, hydro, nuclear, diesel or any other type. Steam power stations are best suited near the coal fields and also adopted where coal supply is available in plenty at reasonable rates, large amounts of power is required to be generated and financial, climatic and geographical conditions … Read more
Generation of Electrical Energy The conversion of energy available in different forms in nature into electrical energy is known as generation of electrical energy. Energy available in various forms from different natural sources such as pressure head of water, chemical energy of fuels, nuclear energy of radioactive substances etc. All the forms of energy can … Read more
