Renewable Source of Energy
Solar energy technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry. There are a variety of technologies that have been developed to take advantage of solar energy.
Renewable energy technologies that make direct use of sunlight include solar panels, which absorb the sun's heat to produce hot water; and photovoltaic cells that use sunlight to make electricity. Secondary solar-powered resources include wind turbines that generate electricity; biomass crops that require sunlight for growth and are burnt to produce heat; and heat pumps that concentrate the low-grade heat absorbed by the air, ground or water in summer to heat buildings in winter and cool them in summer.
Your choice of renewable energy resources will depend on the prevailing climatic conditions, the characteristics of your home, and the relative advantages and disadvantages of each renewable energy source.
