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.
