some chineese firms are exporting these wind turbine systems for electricity. You guyz in karachi can avail this opportunity. I guess its enough to power a whole town. So if the residents of a town can invest this is a good opportunity to free themselves from relying on stupid gov power systems.Once installed No need to pay bills to gov.
A good starting point will be to find out how much bill residents of a town pay per year and how much electricity they use. This will help in calculating how much time it will take to recover their investment.
