You may write a lot information on the Sun and the energy
that Earth receives and how one can use it for useful purposes.
Solar energy that is available at the Earth's surface is
estimated as about 100 penta watts. That is more than the total power
consumption of the world today.
Solar energy lights up the planets in the solar system. Moon is so bright in
the night just with the reflected light from low reflecting materials.
Earth's temperatures are maintained by the Solar energy. Heat from sun rays
vaporize water from rivers and seas forming clouds that rain for months.
We are unable to convert a lot of solar energy into useful energy due to our
technological or economic condition. But solar energy is really powerful that
lasts for a long time to come.
Availability of solar
energy in India -for around 10
months a year for about 11 hours a day. We are near the equator, so there is more sun
Write about the solar energy conversion into chemical energy
through solar cells and conversion into electrical energy. We can write the availability of area above apartments
and on ground for solar panels. The
solar cells have a life time of 20 years.
The investment is retrieved in 3 to 4 years. The solar energy is pollution free.
Solar energy is the
only source available in the space for artificial satellites. Sun light is a renewable energy source. It is available through nuclear fission
chain reaction at very high temperatures in the star Sun. It
will last for millions of years more.
Solar energy does not have shutdowns or cut downs. Even cars (autos) are made from solar energy
You can attach pictures of solar panels, cells, and various
solar equipment or gadgets, solar auto-rickshaw
You can attach some names of big companies which make solar equipment and fix solar systems.
The government also gives subsidy for solar energy equipment. We could mention this also, that governments in many countries including India are encouraging solar energy.
