There is an indispensable need to develop geothermal technologies to supplement the long-term energy needs of Pakistan to a significant level. Geothermal energy is one of the oldest, most versatile and also most common form of utilization of renewable energy. Pakistan is rich in geothermal energy, many of the researchers highlighted and emphasized about its importance, but due to less awareness, lack of confidence and management, no realistic work has been done so far in this domain. This paper investigates the progress of geothermal energy sources, technologies and its potential. Finally the prospects for the geothermal energy sources in Pakistan are described to encourage national and international investment in developing these resources. © 2013 Elsevier Ltd.
