This article will address some of the most intriguing solar
energy facts. Solar energy is generally one of the most ecologically
sound and desirable sources of power these days. Let's get going with
the obvious. Solar power has been in existence since the dawn of time.
It has been used by microbial, plant, and animal life as a primary
energy supply. Plants, using photosynthesis, create nearly all of the
food on the earth and are at the base of the food chain. Furthermore the
fossil fuels we rely on so heavily nowadays are created from plants and
animals that lived a long time ago. Only in recent times have human
beings been able to capture solar energy so that it may be utilized any
time of day and night, and in any weather, stored and transferred.
Annually,
the earth's atmosphere absorbs 3.85 million exajoules of energy from
our sun. This most likely doesn't mean much to you, however by
comparison, the entire use of electric energy by all people today around
the world is just 56.7 exajoules per year. This indicates that within a
few hours, the earth receives more energy from the sun than people
expend during an entire year! Solar energy is a remarkably clean supply
of energy simply because, in contrast to fossil fuels, making use of
this kind of energy doesn't discharge carbon dioxide or other types of
harmful toxins into the environment. Furthermore solar energy is
collected by almost every single form of life. You've almost certainly
never seen a reptile collect wood to start a fire, but you most likely
have seen one lying on a rock to absorb solar energy. Solar power is
probably the most environmentally sound energy option attainable right
now.
Perhaps you may be wondering what exactly solar power is
capable of doing for our environment. Every year, humans consume 467
exajoules of energy by utilizing several principal power sources:
burning coal, gasoline, and oil, along with 'green' sources like wind,
solar, and hydro energy. However, if we could capture just 10% of the
sun's energy, we would have the capacity to replace all of the fossil
fuel sources and have enough space for growth. Without any doubt solar
energy facts like this make it clear how much better solar power is for
the environment and how great the potential is for solar energy
development.
Considering that you've seen some of the most
remarkable solar energy facts and now have an understanding regarding
what solar energy can possibly do for the environment, you'd probably
want to know just exactly what solar energy is. To put it simply, solar
energy is the heat and light energy emitted from the sun. The sun
constantly generates vast quantities of energy into our solar system.
Approximately 30% of the sun's energy that reaches the earth is
immediately deflected by the atmosphere, and another 20% is absorbed
into the atmosphere. However, around 50% of the energy actually reaches
the earth's surface, where it fuels photosynthesis in plants, maintains
both hot tropical and warm temperate climates, maintains the temperature
of the ocean, and generally speaking keeps our planet alive. All of
this is accomplished without creating any pollution or destruction of
natural resources.
A lot of people don't understand how solar
energy functions on the technical level, and so they wonder just what
solar energy is going to provide to their homes, businesses, and
communities. In the last three decades, solar energy technology has
developed at an accelerated rate. Solar energy is gathered at a number
of large power plants in the U.S., Spain, Australia, and in other
nations, where it delivers power directly to the power grid. This
implies that countless houses around the globe already get electrical
power generated by the sun. One of several lesser known solar energy
facts is that solar power can also be employed on a considerably smaller
scale. Solar panels on households and businesses, can certainly create a
percentage (or possibly all) of the power these buildings have to have.
On an even smaller scale, solar panel systems are put to use in India
and Indonesia to disinfect water, and compact solar burners and ovens
are often employed in order to cook food in other regions of the globe.
Solar energy might be employed to power practically any procedure you
can visualize, from large-scale power generation for towns and cities to
boiling a single pot of water.
What makes all of these different
uses achievable is the development of solar energy systems. You will
notice two standard varieties of solar energy technologies presently
used today: solar thermal energy (STE) and photovoltaic (PV) energy.
Solar thermal collectors just harness the heat or thermal energy
generated by the sun. This thermal energy is generally used to heat
water which in turn can easily be stored and used for common every day
requirements or piped to a household heating system. STE may be stored
by heating up or energizing a thermal mass that is designed to continue
to radiate heat even when the sun isn't shining. Solar thermal
collectors actually are significantly more efficient in comparison with
photovoltaic collectors but on the other hand energy storage is somewhat
more cumbersome. Photovoltaic solar panel systems produce electricity
when exposed to sunlight. This electric current may be used immediately
or alternatively stored by using batteries for later use. This is
actually one of the more significant solar energy facts whenever you are
dealing with PV energy systems. Battery storage is incredibly
significant since it means it is possible to store solar power for use
through the night or during cloudy or rainy days.
Solar energy is a
very important alternative power source which can help us take care of
our environment. It can also help to cut down our reliance on fossil
fuels. You may be asking yourself just how big of an expense it is going
to be for you to convert to solar power? Solar power is not really as
costly as most people think. A total solar energy system for a house can
potentially cost more than $30,000, having said that this does not
really mean you will be paying that total amount. To begin with, you
will discover lots of different incentive plans, which include tax
credits, rebates and grants, that may reduce the price of installing
solar panel systems by 30% or more. One other option you might wish to
look into is a smaller solar energy system that just supplements your
household power needs. A smaller sized system will cost considerably
less, while still lowering your current energy bills, and it will
certainly help make your home much more environmentally sound. Currently
most electrical power is generated using fossil fuels. So lowering your
use of electrical power from the area power company by 50% is actually
an important step towards establishing a sustainable power grid.
In
this article, we've made an effort to supply you with a number of
helpful and thought provoking solar energy facts. While you contemplate
these facts, also think about just how much value you put on the quality
of the environment and on humanity's ability to preserve it. No matter
if fossil fuels do not run out during the next 50 years, it's very
likely that their continued use as our primary energy source is going to
wreak environmental havoc. Investing in solar power now might not
instantly help you save money, but your monetary investment can
certainly provide an improved future for everybody under the sun.
