“Sunlight bathes us in far more energy than we could ever need -if we could just catch enough”.
30 year old Bashonti,resident of Noorgunj, a tiny village in the rural recesses of Bangladesh,probably has one of the greenest jobs in the world.She makes a living out of trapping and selling solar power.She knows little about the ongoing global debate on suistainable development and will probably stare blankly if someone tells her the governments of various countries are investing millions to promote renewable resources.Bue she knows every detail of the functioning of a 120 watt solar panel.
Now the question arises as to why we are emphasising on going GREEN? Why do we want to harness the renewable resources when we do have nonrenewable sources like coal and petroleum around as?
Let me answer with respect India. India is the most prosperous country. We are not dependent on foreign countries for other basic goods except petroleum. With the current usage of natural reserves, our oil reserves would last only for 19 years,gas reserves for 28 years and coal reserves for 200 years. Then what ??
Well, we have a solution..SOLAR POWER..
India is geographically placed near the equator. We have the privlige og getting abundant sunshine. A square piece of land in Thar desert, 50 kms. on each side, can cover the entire electricity reqirement of India.
Let’s see how the solar panels work.
1.Excess daytime electricity from solar panels goes to an equaliser.
2. Aided by a catalyst, the solar energy splits water into hydrogen and oxygen.
3.When it’s dark, then the stored elements are combined in the fuel cell generating electricity.
4. Power flows through household appliances and recharges the batteries.
See, now we realised that it is so eco-friendly to use solar energy.
Can solar power save us?
The answer is ‘YES’.But the Govt. needs to invest more in the setting up of more solar panels in various regions where it’s sunny for major part of the year.Barack Obama has pledged to institute a fedral “renewable portfolio standard” which wouls require utilities that would meet 25% of their energy demand by 2025. Similar steps, needs to adopted in India too.
The abstract posted by C.R. Bhattacharya claims that a 150 KWatt power supply can cater to 80-100 watt supply for domestic purposes at a nomial cost of Rs.100-125 per month.
This is the future of SolarEnergy.So, be ready to use it in your own special way. We can go in for solar cookers, solar water heaters (We use them in our hostels! We get really hot water 24/7), solar battery charged calculators etc..
Let us contribute a little in saving energy for the future generations by drifting to renewable sources of energy. I would like to end, with tis quote by Sir George Porter,
“ I have no doubt that we will be successful in harnessing the sun’s energy… If sunbeams were weapons of war, we would have had solar energy centuries ago.”
