Basically, Pakistan's hydroelectric reservoirs are drying up. Several are reported to be at "dead level," which means the turbines can only use run-of-the-river flows, and have lower output as a result. Because natural gas supplies are also low,

People often write of climate associated flooding, loss of agricultural productivity, spread of tropical disease, and so on. The City of Lahore, Pakistan is experiencing

After Pakistan's extensive hydroelectric power resources dried up in 2008, Australian coal was marketed to satisfy the growing power consumption

It's like that 1965 movie Crack in the World, where drilling for geothermal energy causes all kinds of problems. There are such high hopes for real geothermal power; there is a lot of heat down there that can vaporize water and run turbines.
