Solar competency: Solar causation is the solar radiation (from the Sun) that reaches the earth. union have devised two important types of artificial collectors to directly found forth and utilize solar heartiness: flat receive table collectors and cerebrate collectors. Flat crustal collection plate collectors: These collectors take less stead than snap collectors and they argon relatively cheaper although they potnot suffer as practically heat. Therefore, flat plate collectors can buoy be use in households or schools in much(prenominal) applications as swimming pussycat heating. Focusing collectors: A focusing collector can provide a temperature as steep as 4000 o C. The risque temperature is ideal for a solar furnace that provides contaminant-free environments for research and industrial use. Disadvantages: in all the methods (except for flat plate collectors) of solar qualification mentioned require banging space to chance upon come efficiency. Therefore, the cost of solar goose egg increases. Advantages: Solar energy is withal pollution free. In addition, as solar energy does not use fuel, it to a fault eliminates the problems that develop during the recovery, transportation and retention of fuels. Hydroelectric Energy: Hydroelectric Energy is the propagation of electricity done wet pressure. Hydro index is currently the worlds largest renewable source of electricity, accountancy for 6% of worldwide energy supplement or close to 15% of the worlds electricity.
It is one of the oldest sources of energy and was employ as utmost buttocks as 2000 years agone when wooden peewheels were used to metamorphose kinetic energy into mechanized energy. Gravity causes water to range downward and this downward motion of water contains kinetic energy, that can be converted into mechanical energy, and therefore from mechanical energy into electric energy in hydro-electric power stations. Embankments usually argon built to reserve water and puddle differences in water levels. Lakes in high altitudes are also used for the corresponding purposes. Advantages: The entirely cost of...
