I think we in Pakistan can encourage use of Solar energy at small scale, where bank financing can play a very good role. Like for home use banks can facilitate Home users to use Solar panels at small scale at least. I was really surprised when I saw some years before in a remote village of Waziristan ...
Nothing personal!
But this post shows the basic lack of understanding of modern day energy supply systems.
Remember this. In this time and era, we don't just replace Laltain with solar powered candle. Even though it helps to have a light bulb in the house, but that is NEVER the goal of modern energy supply.
In today's world
-------- ordinary people need UNINTERRUPTED and reliable energy
----- BOTH
--------for the light bulb at home,
----AND
--------for the HEAVY machinery in the factories and large amounts of reliable supply to the offices.
Thus the examples of home-solar, makes a mockery of our energy needs by simply trivializing the issue of energy crisis in Pakistan.
Pakistan would soon need 100,000 Mega watts. And we can only produce 15-20 thousand at the moment. Thus we are in a NET deficit of 80,000 mega watts.
And Solar can only provide 0.5 - 1 thousand mega watts by using the BEST and the LATEST available from Germany, Japan, and the USA.
Not only the amount of energy is an issue with solar,
BUT
The TOTAL COST for solar energy is 5-30 times HIGHER than conventional clean-coal and nuclear sources.
Thus for the next 50-65 years, solar **in the world and especially in Pakistan will remain a **fancy, fashionable, and VERY EXPENSIVE item.
The real plan for Pak's energy future must include clean-coal and nuclear. All our effort and policies must be changed and directed towards these two sources. Otherwise we'll continue our downwards trend of becoming another Islamic Emirates of Afghanistan.
