Solar Energy
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.
