WHAT IS SOLAR ENERGY?
21st November 2008 - Solar Energy
Solar energy is energy from the sun. This energy
drives the climate and weather and supports
virtually all life on Earth. Heat and light from the
sun, along with solar-based resources such as
wind and wave power, hydroelectricity and biomess,
account for most of the available flow of renewable energy.
Europe is considering plans to spend more than 5 billion
pounds on a series of solar power stations
along the shores of the giant Mediterranean desert of
North Africa and the Middle East.
More than a hundred generators, each with thousands of
huge mirrors, to convert solar energy into
electricity for transmission by cables under the sea to
Europe and then distributed all across the continent
are members of the European Union, including Britain.
Billion unit of electrical power (Ampersands) can be generated in this way, enough to provide six times
the electricity needs of Europe, which contributes greatly
to the significant reductions in carbon emissions.
At the same time, the stations can be used as stopover points
demonstrated in the Sahara, which are in dire
need for fresh water.
The Prince Hassan bin Talal details of the plan called
DESERTEC (IT Sahara) to the European Parliament.
He said countries must cooperate and Sahara States with
a high energy demand and those with technical
expertise in this area.
Was to broach the subject of a Trans-Mediterranean
Renewable Energy Corporation, a company specialized
in renewable energy and the topic is supported by engineers
and politicians in Europe as well as Morocco,
Algeria, Libya, Jordan and other countries in the Middle
East and Africa.
Europe initially provide financial support for the
development of solar energy
and technology on which they
depend for power generation plants and also to build
prototypes of these stations. After this initial
support for banks and financial institutions and
governments and the construction process that could
cost more than 200 billion pounds over the next thirty years.
'We do not use the best use Sahara' said Gerhard
Physicist Nice, one of the founders of the scheme.
And said 'strike without mercy of the sun over their
heads during the day and heat the ground to
tremendous temperatures. Then the heat emitted from
the ground overnight to the atmosphere. In other
words, and he missed a full of energy. We need to stop
this waste and exploit the vast amounts of energy
associated with the beam solar irradiance us'.
Scientists estimated that sunlight could provide 10,000
times the amount of energy needed by the
human being. But converting solar radiation into a form
that can be used for the benefit of mankind is not easy.
One of the proposed solutions is to exploit the vast tracts
of land to build solar power stations in Europe,
but expensive land in Morocco and Algeria and Libya are
cheap and that they burned the solar Glaring.
The project aims to exploit the land, using cheap technique
known as "the focus of solar energy"
The "concentration of solar energy" consists of a
platform consisting of hundreds of mirrors that cover
large areas of soil per square kilometer, each a mirror
placed carefully so as to control the concentration
of solar beam was focused on rooms full of water (boiler).
Once the beam focus on solar boilers Tbda
temperatures to rise to 800 degrees Celsius. Vihol to water
vapor and then roasted to steam turbines
used in the payment of which, in turn, generate electricity by
generators connected. "This technology was
to prove the efficiency of its work," said Gerhard Nice
and has proved it is working in our test.
Were tested on small stations, but stations will be built
soon be able to generate 100 megawatts and
who need the equivalent of a small town. And aims
DESERTEC (IT Sahara) to set up a panel of the
stations along the northern coast of Africa, part of the
east coast of the Mediterranean. This will
generate 100 billion watts to be two-thirds of energy
consumption locally and one third are exported to Europe.
Britain produces 12 billion watts, this is the reader
to have more sense this hugemount of energy.
There desalination system in addition to the system.
That after the steam out of the pipes pass recycling
turbines submerged sea water basins, which vaporized
and then die to intensify and become unfit for drinking.
"Hsolkm is mainly for electricity and fresh water,
" said Gerhard Nice "and in particular water will be very
important for southern Mediterranean countries
and North Africa, which is experiencing rapid growth in
population and limited sources of fresh water.
Our will not provide the electricity they sell to Europe, but
also provides Safe drinking water for their populations and their thirsty "
"There are disadvantages such as the cost of electricity
generated this way cost from 15 to 20 euro cents
per kilowatt at almost twice the current value and which
is used in coal generation. The cost of the few
countries which will only change to solar energy.
This will not stop People from the use of natural organic
fuels (coal, gas and oil) but if solar energy is very
cheap, "said engineer John Qbins Energy Royal College
in London, the magazine Nature last week.
Supporters of the draft DESERTEC (IT Sahara)
say the developments witnessed by the next ten years
will lead to lower price of energy obtained this way
and the price of a kilowatt hour will be less than 10
Ioroessnt, making it a strong competitor to traditional energy sources.
Some critics say if the factories were built in many
countries not stable is possible that lead to cutting
supplies to Europe. In reply to these criticisms Nice said
"Solar energy is not oil so as to maintain stocks
of other times they are lost if the power had not been
exploited immediately after the crash on the mirrors
and consequently no longer obscured on the hypothesis
of consumers and used as a pressure from them to Europe,"
