The different sources of energy.

Solar heartiness: Solar power is the solar shaft of light (from the Sun) that reaches the earth. community have devised two main types of artificial gatherers to flatbed bring forth and utilize solar heartiness: flat graduated table collectors and cerebrate collectors. Flat crustal plate collectors: These collectors effect less space than focusing collectors and they argon comparatively cheaper although they potnot nominate as much heat. Therefore, flat plate collectors shadower be implement in households or schools in such applications as swimming pool heating. Focusing collectors: A focusing collector can provide a temperature as high as 4000 o C. The high temperature is ideal for a solar furnace that provides contaminant-free environments for seek and industrial use. Disadvantages: All the methods (except for flat plate collectors) of solar talent mentioned require large space to chance upon average efficiency. Therefore, the price of solar nil increases. Ad vantages: Solar energy is also contamination free. In addition, as solar energy does not use fuel, it also eliminates the problems that arise during the recovery, transportation and retention of fuels. Hydroelectric Energy: Hydroelectric Energy is the generation of electricity done irrigate pressure. Hydro power is currently the worlds largest renewable source of electricity, accountancy for 6% of worldwide energy supply or close to 15% of the worlds electricity.

It is one of the oldest sources of energy and was used as utmost approve as 2000 years ago when wooden piddlewheels were used to replace kinetic energy into mechanical energy. Gravity causes water to grip downwards and this downward motion of water contains kine! tic energy, that can be converted into mechanical energy, and then from mechanical energy into electrical energy in hydro-electric power stations. Embankments usually argon built to reserve water and create differences in water levels. Lakes in high altitudes are also used for the equal purposes. Advantages: The only cost of...
