How is solar energy used?

Solar water heaters work by using tubes or panels to collect solar energy that heats the water. Companies and utilities that need large amounts of electricity can use solar arrays -- structures that consist of interconnected solar arrays. read more

Solar energy may be used in a water stabilization pond to treat waste water without chemicals or electricity. A further environmental advantage is that algae grow in such ponds and consume carbon dioxide in photosynthesis, although algae may produce toxic chemicals that make the water unusable. read more

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. Most solar energy is simply reflected (by clouds or snow) or absorbed (in the atmosphere, land, or oceans). read more

Solar energy uses captured sunlight to create photovoltaic power (PV) or concentrated solar power (CSP) for solar heating. This energy conversion allows solar to be used to power auto motives, lights, pools, heaters and gadgets. read more

"I'd put my money on the sun and solar energy," Thomas Edison once remarked prophetically. The sun's potential to provide energy has been demonstrated throughout history. read more

Solar energy is used today in a variety of ways. 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. read more
