Facts about solar
energy - "Encouraging Facts About Solar Energy"
The Earth's First Energy
A fact about solar energy is that the Earth's first energy
was solar energy;
another fact about solar energy is humans have been using
solar energy to make
our lives easier. People have used solar energy to dry food
and bricks nearly
as long as humans have started building cities.
In more recent times, humans have made solar cook boxes as
early as 1830 for
cooking while camping; and more recently, in the 1950's
people created
photovoltaic cells for collecting solar energy and turning
it into electricity.
Progress In Solar Technology
A commonly known fact about solar energy is that the
collection is not terribly
efficient, only able to collect about 10% of the energy they
are subjected to;
today solar cells or photovoltaic cells are able to collect
more like 20% of
the energy they are subjected to.
Another fact about solar energy is that the cells are only
able to collect
the energy for electricity in full or part; the sun, clouds,
mist, and fog
will limit or diminish the solar cell's ability to absorb
solar energy.
A new fact about solar energy is that scientists are working
towards making
new solar cells which are able to absorb UV or ultra-violet
rays from the sun
and convert those into energy; these will create even more
electricity because,
even though the sun is not shining, UV rays are always able
to penetrate to the
solar cells.
The Make Up Of A Solar Cell
Solar cells are made of silicone alloy and are charged with
photons and
electrons to aid in the transfer of solar radiation to
electricity. The
cells are often small, only about 4 inches long, and are
often tiled into
weather proof blocks allowing more electricity to be made as
more sunlight
can be converted.
Solar Energy Is Part Of The Solution
With the world's high demand for electricity, more and more
coal burning
power plants spring up every day; which in turn causes more
pollution.
The fact about solar energy is that it is a renewable and
clean source of
energy, and if it is used in combination with other forms of
clean energy
such as wind power, it can completely fuel a home or, on a
large scale, an
entire city or metro area.
Many states give rebates, grants, and tax deductions to
encourage people to
convert their homes to clean energy; in addition to reducing
the home owner's
monthly bills, a fact about solar energy is that using it in
place of the
utility company's energy will reduce the overall amount of
pollution released
into the atmosphere.
