Thank you for this excellent article. After all the bashing solar has received recently in Pakistan, just because people do not understand the physics of it, this article does a wonderful job in clearing up the confusion. At the end of the day, however, to end the energy crisis in Pakistan, we also need to reduce our demand. Our current consumer end appliances are nowhere near the world class efficient appliances available in the rest of the world. Just by comparing appliances, cars and lighting options, and buying the most efficient ones, we could cut our demand by at least 30%.
