The energy of the sun
E
very
day the Sun radiates,
or sends out an enormous amount of energy. It radiates more energy in
one second than people have used since time began.
Where does all this energy come from? It comes from within the Sun itself. Solar energy is the most popular energy. How can we use this free energy?
We've used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it for generating power. It seems that solar energy is everywhere in one way or the other. So, we can say that solar energy is a thing for the future.
The Sun
is 150 million kilometers
away and amazingly
powerful.
It is also a useful, cheap and reliable
electricity source. Just the tiny fraction
of the Sun's energy that hits the Earth is enough to meet all our
power needs many times over. Every minute, enough
energy arrives
at the Earth to meet our demands
for a whole
year – if only we could use it properly.
Due to solar
energy we are able to run
technology
and various
machines like
aircraft, car etc. without using fuels.
Advantages of solar energy
Solar energy is free – it needs no fuel and produces no waste or pollution.
In sunny countries solar power can be used where there is no easy way to get electricity to a remote place.
Solar power is renewable. The Sun will keep on shining anyway, so it makes sense to use it.
Disadvantages of solar energy :
it doesn't work at night;
it is very expensive to build solar power stations;
it can be unreliable unless if you live in a very sunny climate.
