Renewable Energy Sources Worth Tapping Into
By John M Saragunter
If you want to go by a strict dictionary definition,
renewable energy could include heating buildings by
burning all the forests in the world, because as the
trees are replanted, they’ll eventually grow back again.
But nobody advocates such an extreme, even if trees
are "renewable." What people really mean by
"renewable" is that any resources used will
be replenished not just by natural means, but also within
a reasonable length of time.
Using these resources won’t leave the reserves empty
for a long time, but the supplies remain almost constantly
available. You might think of this as sustainable energy,
to be more strictly accurate.
Coal, Natural Gas And Oil Are Formed Over Millions
Of Years
Renewable and clean energy therefore automatically
excludes resources such as coal, natural gas and oil.
While it’s true that all of these are originally derived
from plant or animal material, all of which are technically
"renewable," the processes that form these
energy sources take millions of years.
That takes them well out of any time frame for renewable
power that could be used by human beings right now.
Add to this the effects of global warming from releasing
these hydrocarbons into the atmosphere, and these types
of energy sources are not desirable anyway. They are
the reason alternative energies are needed.
Geothermal Heat, Wind And Solar Energy
So what is a renewable energy source, then? It’s something
that occurs naturally in the world and is a process
that is already going on, which human beings can tap
into. For example, geothermal heat is the natural heat
that is stored in the earth, which can be extracted
and used.
Wind is another source, as it can be used to turn the
blades of wind turbines and other sorts of windmills,
to generate renewable electricity. And of course, the
rays of the sun flood the earth with constant solar
energy that just needs to be collected and converted
into usable power.
Impact On The Earth
Green energy solutions are not just trendy, but have
a real impact on the earth and its inhabitants. Not
only do these renewable energy resources leave the earth
less damaged, but they help people live in greater harmony
with nature, instead of feeling like they are at war
with it.
Oil, gas and coal result not just in damage to the
earth from the extraction methods necessary to acquire
them, but their long term effects on the world are even
more damaging. It is far better to use renewable, clean
resources that will give the earth and living things
a chance for a healthier future.

Little Known Green Energy Facts.....
What are first generation green energy technologies?
First generation green energy technologies
are usually those most heavily advertised. But they
are also dependent upon how plentiful the resource is
in that particular area. Some areas are better suited
to first generation technologies than others.
A great example of a first generation
technology is hydroelectricity. Decades ago when people
realized that energy could be found from the flowing
water through a dam, many areas that had natural reservoirs
began to create these concrete plants. The result was
a cheap form of electricity that had very little carbon
footprint.
