An Introduction to Solar Power
In today's (2014) climate of growing energy needs and increasing
environmental concern, alternatives to the use of non-renewable and
polluting fossil fuels have to be investigated. One such The alternative is
solar energy
Solar energy is quite simply the energy produced directly by the sun and
collected elsewhere, normally the Earth. The sun creates its energy
through a thermonuclear process that converts about 650,000,0001 tons of
hydrogen to helium every second. The process creates heat and
electromagnetic radiation. The heat remains in the sun and is instrumental
in maintaining the thermonuclear reaction. The electromagnetic radiation
(including visible light, infra-red light, and ultra-violet radiation) streams
out into space in all directions.
Only a very small fraction of the total radiation produced reaches the
Earth. The radiation that does reach the Earth is the indirect source of
nearly every type of energy used today. The exceptions are geother
