Most of Pakistan electricity comes from burning fissile fuel, especially crude oil. In July and August, crude oil price touched $140 a barrel, so price of electricity production gone up.
Anyhow, today crude oil is selling at around $65 a barrel, almost half of what it was in June/July 2008. So, high price of electricity and petrol that government decided to charge couple of months ago are not justified. Actually, today price is substantially higher than last year because government has taken away most subsidies and due to rupee devaluation, else crude oil price is lower than last year, and thus Pakistanis should pay lower electricity bill and petrol price what they were paying last year.
