thoughtfull article
It is very encouraging to know that pakistanies are thinking loudly about sustainable solutions to the very serious nergy crisis. She is right to think that our secure and sustainable future lies in the exploitationm of renewable energies of solar, wind, hydro and biomass. these sources will generate energy and employment for prosperous Pakistan. |

Coal for Paks
Bio-fuels,Renewable energies, wind power, solar power and many other off track or slightly on track sources of energy have been in use or talked about to substitute a very small fraction of the main sources that are oil, gas and coal.
I was personally involved in renewable energy with my renewable energy company's name as renewable energies as well in Canada.All advisors to US presidents since Nixon have been advising US government about bio-fuels etc., but with the land and all other resources put together can substitute only 5 percent of current energy use from oil, gas, coal and less of hydro-electric power.India spent 12 billion dollars on wind power mega project, but the recovery was only 6-8 percent of design due to irregular, low velocity and ever changing direction and intensity of wind.My own renewable energy business in Canada in which the owner of a Canadian engineering consulting company was my partner, went to business failure.My own money earned from consulting on oil and gas was lost in business.
Now come to solar power. First there is not enough of poly-silicates in the world to make the required solar panels. Then in running cars, you have to power the batteries for 80-90 hours to drive your car for only 20-30 minutes. Third solar energy dissipates and distributes itself with certain limited threshold patterns.Even if you switch to some iffy solar, you will leave some hot and cold geographical spots in the world.
Oil, gas and coal are the great energy blessings to mankind.There will be total upsets and human cataclysmic disaster once you find the world has run out of oil, gas and coal.Before oil and gas revolution starting 1900, the world could not even support 1.5 billion people without famines and starvation. It is only oil and gas related fertillizers that our planet earth can support 7 billion people.The world will fight and destroy itself out once the oil, gas and coal is gone.
Pakistan is very fortunate to have the second largest coal reserves in the world and that is the ultimate energy survival of Paks. Unfortunately, Paks have not yet developed its coal for power and other uses.
The world has 1200 billion barrels of oil, 6400 trillion cubic feet of gas(equivalent to 1200 billion barrels as imm scf of gas equals 180 barrels of oil).Pakistan has 200 billion tons of the world's 1000 billion tons of coal and one ton of coal gives as much energy as 1.6 barrels of oil on average.Pakistan must develope its coal as much fast and preferably with China's help because, western companies and business structures eats away all leaving nothing but debt behind for the people who even own their resources.China will be much better player for Pak's coal development. |
