Solar energy is a
renewable, clean energy that has been around for thousands of
years in one form or another. Following are the key solar energy
facts.
Solar energy is
all about harnessing the power of the sun to produce energy. The
sun rains enough solar energy on the Earth in one day to power
the entire energy needs of the world for one year. Solar energy
is considered a renewable energy source because it will exist
for as long as our sun does, estimated to be another 4.5 billion
years. Solar energy is also considered a clean energy because it
does not produce pollutants or byproducts harmful to the
environment.
Solar energy was
the first energy source used by mankind. Of course, the use was
limited to drying things and heating caused by direct contact,
but it was a use. In modern times, solar energy has been a power
source since the early 1950s, but was not widespread due to
technological issues which rendered it an ineffective and
expensive energy source. With technology advancements, solar
energy is moving to the forefront as a potential alternative to
fossil fuels.
The future is
indeed bright for solar energy as new solar nanotechnology is
close to creating solar platforms that boggle the mind. For
instance, a few companies are trying to create solar quantum
dots, which will be mixed in the paint you use for your home.
Yes, you will actually paint on solar energy panels that will
power your home.
