Alternative
energy refers to several sources of usable energy meant
for supplementing or replacing conventional energy
sources like fossil fuels (coal, petroleum, etc). These
include geothermal, bio-fuels, biomass, hydroelectric,
solar energy, wind power, nuclear, etc. It is often
synonymous with renewable energy, although
alternative energy need not
necessarily always be renewable.

Although
scientists had been reminding us all the while that the
world’s fossil fuel stock is depleting fast and unless
some form of alternate source of energy is found right
away, human civilization may come to a jarring halt, no
one seemed to pay heed to it. The matter however took a
serious turn when the US national average price per
gallon of regular unleaded gas rose above $4.00 in the
current year, sending people scurrying for alternative
sources of energy. Meanwhile, rise in oil price also
affected average American homes. Electricity became
dearer with the result that heating homes in the winter
became more expensive while air conditioning in the
summer turned out to be very pricey. Energetic American
business community, ever eager to take up challenges
took this opportunity to prove their worth. Like ducks
to water, they went headlong into the core of the
problem and came up with a couple of very practical
solutions. The sun and the wind, they found to their
advantage, were the source of two naturally renewable
form of energy that could be easily tamed to provide the
much needed electric power practically free of cost to
every home.
Taking
the cue from their Scandinavian friends, they built wind
turbines (not giant wind mills) which when coupled to a
generator, could easily satisfy the electricity
requirements of an average US home. Some manufacturers
also began to offer do-it-yourself turbine kits that are
much cheaper as compared to custom built ‘Home Wind
Turbine’.
While
home turbines were gradually gaining ground as
alternative energy source, yet another
set of entrepreneurs were keeping themselves busy with
extracting power from sunlight. Scientists at the Bell
Laboratories had already proved that photovoltaic cells
could magically turn sunrays into DC electric power.
Transformed into 120 volt AC current, this renewable
power could also provide the much needed electricity to
homes and workplaces. Clustered into photovoltaic solar
panels, these were mass produced soon to almost replace
conventional grid power that was becoming more and more
expensive to average American
homes.
According
to the new US President Barack Obama’s “New Energy for
America’ plan, ‘there will be one million plug-in Hybrid
Cars on the roads by 2015, reduced greenhouse gas
emissions by 2050 and 25% assured alternative
electricity in the US by 2025. Undoubtedly, such a bold
plan would mean massive investment involving hundreds of
thousand private sector investors and business persons,
leaving aside industrial giants who would not think
twice before putting money in this newfound
field.
Much like wind
turbines, solar power systems can now be also installed
at your home. And the best news is, you can install the
home solar panels yourself very easily. You can yourself
do the installation, provided you know where t set it up
and how to do it. Plus you will also have to know where
to get the parts including the solar electricity home
kit from, how to wire the system and also the safety
precautions. Solar power offers great advantages because
it is ecologically friendly and it also reduces the
electricity bills.
