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.
