Even
though solar energy is the first kind of energy that is thought of
when someone mentions alternative energy, it is far from being the
only kind. Perhaps, the solar energy is more popular simply because
it has been used more than the other types.
But, with advancements in technology in recent years there is an increase
in other forms of alternative energy that people are beginning to
use more and more.
The different kinds of alternative energy will be discussed here,
as well as the advantages and disadvantages of employing these kinds
of energy.
• Wind energy – Wind energy is harnessed by windmills.
When the wind blows, these windmills are able to harness the wind
by spinning. As the windmills spin, an electrical current is generated
and used to produce energy.
Obviously one of the big advantages of using a system that runs on
wind energy is the price. Because electricity costs have increased
as mush as 50 percent in the last few years, many people are looking
for any kinds of options to decreasing this price.
In some ways, the wind energy can help decrease the cost because the
homeowner does not need to pay high prices for fossil fuels. However,
many of the power companies are unable to or unwilling to invest in
wind farms.
Because it can take a lot of land and a lot of windmills for a large
power company to produce enough wind to power the homes within its
market, many of the power companies are unable or unwilling to pay
the prime prices for the amount of land that would be needed to harvest
the wind.
• Solar energy – Solar energy is energy that is collected
by PV panels and converted to electricity that can be used in a home
or even on the campground.
Those who are looking for the biggest savings usually use these panels
on their roof to collect the UV rays from the sun. Although some think
that a cloudy day could cause problems, this is not necessarily true.
A homeowner has different options when using solar energy. First of
all, he can simply use the energy that is being collected in the day
time and then use other energy during the night.
Secondly, the homeowner may choose to use a battery in which the excess
energy can be stored. This is wise, especially in those places where
there is a lot of sunlight and the energy collected exceeds the amount
of energy that needs to be spent during the day.
By storing the energy, the homeowner can use the energy throughout
the night and at other times when large amounts of solar energy are
not being produced.
Lastly, one of the things that many homeowners choose to do is not
exactly use the harnessed solar energy themselves, but instead hook
up their alternative energy system to the local power grid and “sell”
back the energy to the power company.
Because power companies recognize a good deal when they see one, they
will often readily offer credits for solar energy that is transported
into the electrical grid. This means that the homeowner is still technically
using the power company’s energy, but in all actuality is taking
matters into his own hands and saving large amounts of money.
The market for alternative energy continues to grow s natural resources
have continued to become more depleted with each passing year. Those
who use these kinds of energy are likely to see large savings in their
utility bills, but it could take several years for the systems to
begin paying for themselves.
Depending on what kind of alternative energy system a homeowner uses,
it could take up to 10-15 years before real results and savings are
seen.
