Better Utilization Of Solar Energy

The surface of the earth receives solar energy at an average of 343 w m 2.

Better utilization of solar energy.

Using solar energy can have a positive indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. In only one hour the amount of energy that shines on the earth equates to the amount used by the world s population in an entire year. Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area. Solar energy harvesting the power of the sun through the use of photo electric panels or other collection techniques is no longer just a green dream or a concept that universities and businesses experiment with.

Solar energy systems power plants do not produce air pollution water pollution or greenhouse gases. This will also help to reduce your carbon footprint. The future of solar energy considers only the two widely recognized classes of technologies for converting solar energy into electricity photovoltaics pv and concentrated solar power csp sometimes called solar thermal in their current and plausible future forms. Even in sunny parts of the world s temperate regions for instance a collector must have a surface.

Solar thermal power where sunbeams are reflected and concentrated on a heat retaining medium such as salt or graphite to store heat for later use in generating electricity costs even more. Use of solar cooker. Solar water heater solar light bulb solar furnaces solar water heater etc. Because energy supply facilities typically last several decades technologies in these classes will dominate solar.

Solar energy is radiant light and heat from the sun that is harnessed using a range of ever evolving technologies such as solar heating photovoltaics solar thermal energy solar architecture molten salt power plants and artificial photosynthesis. Today there are practical ways that you can make use of solar energy in your home. This allows much more of the energy in the sunlight to be turned into electricity. In addition to being free as a source of energy it does cost money to harness it and turn it into electricity energy from the sun is practically limitless.

Why solar powered energy is rising above fossil fuels. Mankind has developed a way to utilize the sun s vast energy by converting its sunlight into electricity via photovoltaics and other solar power methods. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. The use of a solar cooker is very helpful in saving the earth.

Among the most common devices used to capture solar energy and convert it to thermal energy are flat plate collectors which are used for solar heating applications.
