Solar energy is energy that comes from the sun. This is good for the environment
because it is not using up fossil fuels, and the sun's energy cannot be wasted. Just recently
in the 19th and 20th centuries, people began to re- examine solar energy to fit more ways
to capture and use it.
Solar energy is a renewable source, which means it is good for the environment.
Coal, oil, and natural gases are other recourses, which when burned are used for energy.
However, these resources are limited, and we will soon run out of the natural gases. The
gas and fuel that cars run on are very harmful to the atmosphere and add to the
greenhouse effect. The greenhouse effect causes pollution and unnatural heating of the
earth. the only way to prevent this from occurring is to promote the use of solar energy.
Researchers are interested in changing the sunlight into electricity.
Many methods of
sending heat through air are presently being tested in Israel and Spain.
My prediction is that solar energy will become more common in the future because
there is a limit to the fossil fuels. There is no limit to the sun's energy.
Solar energy is heat and light and electromagnetic radiation, which comes from
the sun. Even though there is no cost for the sun to shine, it is very expensive to turn
those rays into harnessed energy. Solar panels have to face the sun directly for them to
work effectively. Solar cells use materials, like silicone which are semiconductors to
change sunlight into electricity.
Solar energy can also work on days when the sun isn't out. Scientists at the
Weizman Institute in Israel found a new way of storing solar power. They circulate water
through collector plates with...
