The rapid depletion of traditional sources of energy (coal, oil, and natural gas) and an ever-growing demand for energy have turned the world's attention towards development of alternative energy resources. Renewable-energy systems use resources that are constantly replaced by nature and usually have less impact on the environment. COMSATS' areas of interest include energy derived from biomass, solar and micro hydel technologies.

Under the project support from UNESCO and with technical assistance of Pakistan Council of Appropriate Technology (PCAT), COMSATS has installed some Bio-gas plants in the suburbs of Islamabad, Pakistan. These are being used successfully by the locals for cooking & heating. Another project of 1 Mega-Watt Solar-thermal power plant for Pakistan has been provided funds by UNESCO and will soon be implemented. Work has also been initiated on development of Hydel Power Plants in Pakistan, in collaboration with Pakistan Council of Appropriate Technology (P.C.A.T) and Hangzhou Regional Centre (Asia Pacific) for Small Hydro-Power (HRC). The purpose is to provide decentralized low-cost energy to the surrounding rural/industrial areas, which are off the national grid and have little chance to get access in the near future.
