Solar energy today s need.

Solar energy systems today can now used to power homes cars appliances businesses and cities. As of 2011 the technology produced less than one tenth of one percent of global energy demand. Solar energy is the technology used to harness the sun s energy and make it useable. There are locations where solar energy is practical.

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. This is enough capacity to power the equivalent of 12 million average american homes 1. Solar energy is captured in a variety of ways the most common of which is with photovoltaic solar panels that convert the sun s rays into usable electricity. Aside from using photovoltaics to generate electricity solar energy is commonly used in thermal.

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. Since the beginning of 2014 the average cost of solar photovoltaic pv panels has dropped nearly 50 2. Despite the enormous energy flux supplied by the sun the three conversion routes supply only a tiny fraction of our current and future energy needs. Has some of the richest solar resources in the world.

It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. After the solar technology equipment is constructed and put in place solar energy does not need fuel to work. It also does not emit greenhouse gases or toxic materials. 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.

Installations have grown 35 fold to an estimated 62 5 gigawatts gw today. Markets for solar energy are maturing rapidly around the. Solar energy is used today in a variety of ways. Solar energy is clean.

Using solar energy can drastically reduce the impact we have on the environment. 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. Solar power is usable energy generated from the sun in the form of electric or thermal energy. Solar photons convert naturally into three forms of energy electricity chemical fuel and heat that link seamlessly with existing energy chains.

Solar energy is the cleanest and most abundant renewable energy source available and the u s.
