Keep burning coal? Heck they barely burn any to start with.
Gross electricity generation in Pakistan increased gradually over the past decade from 90 billion kilowatthours (kWh) in 2005 to 110 billion kWh in 2015. Key sources of power production in 2015 were oil (35%), natural gas (29%), and hydroelectricity (30%), according to the Pakistani government. Nuclear generation made up 5%, and wind and imported electricity from Iran accounted for 1%. Natural gas supply shortages over the past several years have led to an increased share of oil use in power generation.
