1. INTRODUCTION
Comparing with other developing countries, Pakistan is facing serious energy
crisis since the past several decades leading to an ever–increasing energy
demand necessitating making it seriously dependent on import of pricy fossil
fuels. In the villages of Pakistan, there is almost no electricity & cities are facing
bitter load shedding problems (Ashfaq & Ianakiev, 2018). Load shedding is
14–18 hours in villages and 8–12 hours in cities. The customers located in
residential, industrial and commercial sectors are badly aected making it an
immense challenge for the government sector power infrastructure to ensure
sustainable power. If we do not encounter these burning issues of electrical
energy on a priority basis, then in future there will be the worst situations
of electricity in Pakistan. A large number of research attempts is needed to
explore the renewable energy (RE) resources to attend the gap between the
supply and need. However, the renewable energy sector is yet to penetrate
in the present conventional energy infrastructure predominantly located in
northern and central regions (Kamran, 2018).
Pakistan has energy resources, renewable and non–renewable. Renewable energy
is considered environment–friendly while the non–renewable energy is harsh
for the environment. The sources of renewable energy are solar, wind, tidal,
geothermal, biomass, hydro and thermal. Mostly the developed countries of the
world depend on non–renewable energy resources to meet the energy demands.
Also, the developing countries especially Pakistan still rely on the expensive fossil
fuel based energy system which is expected to deplete shortly (Sher, Murtazs,
Addoweesh & Chiaberge, 2015; Tahir & Asim, 2018). The non–conventional
energy resources have been exploited to reduce fossil fuel–based local and
commercial consumption bit by bit. As such, energy has earned the best quantity
of attention globally than ever before. The energy crisis is already aecting the
developing countries like Pakistan. Pakistan has 93.5% electricity rely on the oil,
natural gas, hydropower, nuclear energy, coal and a little bit on the RE. Pakistan
is mostly dependent on expensive fossil fuel. Pakistan utilizes 25.7% of natural
gas, 37.2% of oil, 30.7% of hydropower, and 4.8% of nuclear energy (Index
