The Spotlight Shines
Brightly for Solar Energy
By Jeanette Joy Fisher
No matter what you may have heard, solar energy is the
wave of the future, in large part because of its utter
simplicity. A photovoltaic, cell collects energy from the
sun, and that energy is converted into electricity without
the use of chemicals, liquids, or moving parts. It's that
easy.
A number of solar cells are generally linked together on a
solar panel, hooked up in series to allow all the cells to
work in unison. The energy that's generated is then stored
in a battery, in the form of DC current. Since most
household appliances run on AC current, the electricity is
then converted to AC current by a device called an
inverter.
The efficiency of photovoltaic cells has improved a great
deal over the past few years, but it still would take a
huge array of panels to run your entire house with solar
power. Even so, it's still possible to use solar to power
at least a portion of you home at a relatively minimal
cost. For instance, you could power your home computer and
a few other small electrical appliances using a system
that costs about $1,000.00 to have installed. At the
moment, solar systems generally cost about $10.00-$12.00
per watt.
Since it's totally renewable and doesn't pollute, it's
easy to see that the future of solar power is so bright.
If we could harness just one hour's worth of the suns
total solar power every day, we'd have enough energy to
fuel the entire planet's energy needs for a whole year.
That's an amazing amount of potential power, and it's just
waiting for us to tap into it.
As photovoltaic cells continue to improve, the cost of
solar energy will keep coming down, and eventually, it
will become economically feasible for everyone to switch
to solar. Enormous amounts of money are being poured into
solar research--some of it from seemingly unlikely
sources, such as a number of major oil companies. However,
that shouldn't really come as a surprise, because they can
see the handwriting on the wall as well as anyone, and
it's clear that they, like most forward thinking people,
understand that the future of the world's energy lies in
solar power.
