When we talk about renewable energy, there
are many different options fields. Recently, wind energy renewable energy seems
to be the favorite. However, experts believe that solar energy could be at the
edge of a revolution. Because people are now more aware of how much solar
energy is generated annually in the end.
According to experts, in the earth receives
solar energy equivalent to an annual 12.2 trillion watts. Exact, it is like all
human energy consumed in a year more than 20,000 times. Therefore, if there is
so much solar energy can be supplied to the earth, why do not more companies to
invest in renewable energy in this form it? Fact situation, making use of solar module energy is too expensive. Due to high cost of solar energy production of the
world's total with only seven percent.
According to the U.S. Department of Energy
is understood that solar costs about $ 156 per MWh. Such a high cost, difficult
for companies want to invest in solar energy, because the cost of coal per MWh
of energy produced is only $ 99. Most importantly, the U.S. is booming
period of natural gas, natural gas per MWh of energy produced only costs about
$ 65. Therefore, it is clear, from an economic point of view, is not really a
good choice solar energy.
Worse, experts say because the home solar panels energy
storage is difficult, so the solar still a realistic choice. After all, only
produce solar energy during the day. Therefore, solar energy must be well stored,
so that it can be used at night.
However, the solar panel to be more
efficient. According to reports, in the 1970s, solar panels solar energy can be
converted into energy with only 8% of today's solar panels become more
efficient, up to 44% conversion rate. Of course, the conversion rate of the
solar cell will continue to rise. Currently, researchers are busy developing
new technologies that will be able to put 54% of the light into energy.
Of course, this will inevitably reduce the
production costs of solar energy. If this improvement program lasts 8 to 10
years, the U.S.
solar per MWh will only cost about $ 120. This will make it compared with other
forms of energy will be more competitive, such as nuclear power and coal.
