Why Should You Harness Solar Power?

Dear Friend,

Very simply put, ‘Solar energy’ is energy
that is derived from the sun. Our sun is an
abundant source of energy; it gives of heat
and light.

The sun’s been revered by several
cultures of the past and even by a few
cultures still present today. The ancient
Egyptians even worshiped the sun as a God.

All said and done, it was not misplaced
respect; the sun certainly is an abundant
and limitless source of power, at least for
several generations to come; the merits for
using its solar energy are numerous.

It’s free

Every morning with each dawn, the solar
energy released by the sun comes filtered
through our atmosphere providing light and
helping to radiate heat.

This has been happening for millions of
years yet it is only recently that we have begun to
capitalize on this abundant source of almost
infinite power.

In the past the Greeks and the Egyptians
have been known to harness the power of the
sun to heat whatever they wished to by
concentrating its radiation.

It’s non-polluting, and earth friendly.

The energy from the sun is clean and free
of any pollutants; unlike various sources of
energy present today like petroleum or
organic fuels that leave back residues and
often leave back harmful gases when utilized
to create energy.

Extremely reliable, because it powered by
the sun…

The sun has been burning for roughly four
and a half billion years now and is likely
to burn on for another four to five billion
years to come.

That’s definitely more than
our lifetimes and certainly more than
several generations of the future. Every
morning it promptly shows up and vanishes
for the evening while it lights up another
portion of the globe.

The saying “as sure as day” did not come
about for nothing; assuming the sun is
shining brightly, depending on which part of
the globe you are you can harness the energy
of the sun to either store it away or
utilize its energy in a different way.

Limitless amount

There is no restriction on how much energy
we can use from the sun. Apparently, the
amount of energy that comes from the sun
every few minutes if successfully harnessed
can power the entire United States of
America for a whole year. If we were only
able to harness the immense energy of the
sun we would be able to solve all the
worlds’ energy problems.

Why would you?

Ever wonder why no one thought about this
earlier? How come if there’s so much energy
just lying around, we simply cannot seem to
efficiently harness it? How it that so much
of the sun energy seems to go totally
unnoticed and is ultimately wasted?

Well one of the reasons that this wonderful
power reserve is generally wasted is the
fact that the sunlight that we actually
receive is so thinly dissipated across the
earth to be able to contribute substantially
enough if we try to harness it.

For us to be able to actually harness the
power of the sun we have to be able to
manipulate, focus and store the sun’s
energy.

While this may seem simple it is
easier said than done; So far we have only
managed to develop three partially
successful means of collecting solar energy.

The Reflection Method – Mirrors / Parabola

The reflection method is based on the
concentration of the sun’s rays through a
single or a set of mirrors onto one point
and then utilizing the concentrated heat
energy that is produced for out need.

A parabolic mirror much like a dish antenna
can be used to capture the sun’s rays and
focus them on a single point.

The radiation method

This is the principle behind the solar
water heaters. Painted black pipes
sandwiched between two layers of glass, have
water inside them that is heated thanks to
the rays of the sun.

Your Solar panels

A more recent invention the ‘solar cell’ is
composed of treated silicon crystals, which
when hit by the rays of the sun knock
electrons out of their orbits and thereby
create a void that needs to be filled by
electrons from the other silicon crystals,
this creates an imbalance of electrons and
hence a flow of current which can be either
immediately utilized or else stored away in
a rechargeable battery.

What’s stopping us?

Despite the apparent benefits of using
solar power it is most unfortunate that
there are very few solar power plants around
the world. Sadly, with today’s level of
technology, cost and reliability are two
major factors that are still hurdles in the
way of mass usage of solar energy.

Technological limitations dictate that the
most efficient solar cells created today are
still not capable of generating enough power
to be commercially viable without occupying
huge surface areas.

Furthermore, reliance
exclusively on solar cells in not yet
practical, for if there were to be a cloudy
day it could reduce the amount of
electricity generated and that would be
disastrous for those people completely
reliant on that energy.

On the bright side, constant innovation and
research on solar energy is resulting in
much more efficient solar cells that are a
fraction of the size of existing cells and
churn out much more power. For now they are
still expensive, but not far is the day when
they will be affordable and available to the
common man.

All the best,
Jeff Davis

 

Spray-On Solar-Power Cells Are True Breakthrough

SOLAR REVOLUTION – Solar Paint Ted Sargent is a pioneer in solar science. He’s working on solar technology that could literally be woven into every aspect of daily life, from our clothes to our roads, using what is known as a spray-on solar cell. The implications for our energy systems are profound. As Ted says, “Solar energy is not just an exciting science problem, but an incredibly important human problem.” Ted is working on solar nanotechnology with the potential to make solar energy very cheap and allow society to collect it on a huge scale. Currently, solar technology costs more to build and install than most people are willing to pay. Solar panels, for example, the technology most commonly associated with solar energy, are installed on your rooftop. The cost of collecting one kilowatt per hour of solar energy (about a third of the electricity an average household uses on any given day) is about 000. Not only are panels expensive to install, they capture only the visible portion of the sun’s rays so they work only on sunny days. Ted’s focus is the infrared portion of the sun’s rays which accounts for more than half of all solar energy. What’s more, infrared energy is available to us even in cloudy weather. A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band holes) in all three spatial directions. The confinement can be due to

Alternative Energy for Your Home

Alternative Energy for the Home

The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond. We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from unstable nations who are often hostile to us and our interests. But even beyond this factor, we as individuals need to get “off the grid” and also stop having to be so reliant on government-lobbying giant oil corporations who, while they are not really involved in any covert conspiracy, nevertheless have a stranglehold on people when it comes to heating their homes (and if not through oil, then heat usually supplied by grid-driven electricity, another stranglehold).

As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy microgeneration. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free. Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, microgeneration (meeting all of one’s home’s energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.

Carbon Free’s analyses also show that energy companies themselves have jumped in on the game and seek to leverage microgeneration to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install. However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.
