Pakistan is rich in terms of clean and sustainable energy sources. Although Pakistan’s energy infrastructure is making some progress but most of the new capacity addition plans are not sustainable and beneficial for the environment. The whole world is moving towards alternative and sustainable solutions of energy. Pakistan should also diversify its energy mix by harnessing vast potential of natural resources such as hydropower, solar, biogas and wind available in the country. This paper aims to elucidate the relation between economic growth and energy consumption of Pakistan using Long-Range Energy Alternative planning system (LEAP). Different scenarios of energy model has been adopted to evaluate energy demand for 2016 and predicted till future year 2045. This research also postulates and uncovers the innovative horizons for the energy planners and policy makers to accomplish the prevalent energy demands in upcoming years. The renewable energy future prospects are encouraging in the country and it can be utilized to overcome the power shortage issue. The diversification of existing energy resources and exploration of new sources is an important aspect to be considered in order to have a sustainable power development and its implementation in the country.
