Solar Energy How Is It Used

Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area.

Solar energy how is it used.

Even in sunny parts of the world s temperate regions for instance a collector must have a surface. Solar energy is the technology used to harness the sun s energy and make it useable. Solar cells and solar panels allow us to harness that energy offering renewable methods of generating electricity. Most of the sun s energy is not used by life on earth since photosynthesis only harnesses a fraction of incoming solar radiation but it still captures about 6 times more than the rate of power consumption by all of human civilization.

Homes and other buildings use passive solar energy to distribute heat efficiently and inexpensively. In some countries for instance solar energy is used to produce salt from seawater by evaporation. Insolation levels are important for the technical and economic performance of solar energy systems. Solar energy systems today can now used to power homes cars appliances businesses and cities.

Where solar energy is used. 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. The opportunities solar power presents has made it the. Passive solar energy techniques take advantage of this natural heating and cooling process.

It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. The availability of financial and other incentives for solar energy are also major factors that influence where solar energy systems are installed. As of 2011 the technology produced less than one tenth of one percent of global energy demand. Solar energy is used today in a variety of ways.

Solar energy is also used on a small scale for purposes other than those described above. Solar energy is the transformation of heat the energy that comes from the sun it has been used for thousands of years in many different ways by people all over the world. How is most solar energy used. This is where solar energy is used most in the world.

The oldest uses of solar energy is for heating cooking and drying today it is also used to make electricity where other power supplies are not there such as in places far away from where people live and in outer space. Calculating a building s thermal mass is an example of this. A building s thermal mass is the bulk of material heated throughout the day. 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.

While the sun is a continuous and powerful source of energy the question is where is solar energy used here on earth. Probably because today more and more people are understanding the advantages of solar energy as our solar technology increases and the cost of fossil fuels rises.
