Sustainable Energy along with Renewable Energy Sources > 자유게시판

Sustainable Energy refers to energy produced from natural resources that are replenished in the regular course. Energy from the sun, dark age defense scam - simply click the following page - wind energy, tidal energy, etc as well as energy extracted from biomass and biofuels fall in this class.

We shall briefly look at the major renewable energy systems:



The sun has a surface temperature of aproximatelly 27 million deg. C. and emits radiations covering a wide variety of wavelengths in all directions. A element of the radiations fall on the planet earth as it goes round the sun. Allowing for the various losses of the radiation on means to the world, on an average we get aproximatelly 800 W/m2 of solar energy in the equator.
Solar radiations incorporate infrared frequencies which offer heat and also visible radiations which provide light. The solar energy, therefore, could be used in a very versatile manner. Photovoltaic cell-assemblies as arrays and panels are used in isolated homes and communities for providing electricity; they are in addition used in huge power stations for utility supplies. Heat for industrial processes as well as for supplementing the large thermal power stations is supplied by using the solar concentrators in big installations.
