When the country was going through a severe energy crisis last year, the president had called for stepping up the search for out-of-the-box, imaginative and bold solutions based on alternative energy to meet the country’s needs. One such solution that has emerged is a wind-powered turbine for road illumination. As reported in this paper, a locally designed pilot wind turbine has been installed on a streetlight in a major thoroughfare in Islamabad. The privately developed turbine harnesses energy from natural as well as traffic wind and stores it in a battery that can power the streetlight’s bulbs for 48 hours.
But all these advantages can only be reaped if there is official facilitation of the pilot turbine’s manufacture on a large scale and its widespread deployment by municipal authorities in their localities. In this respect, the interest and cooperation of agencies like the Capital Development Authority and the Engineering Development Board of the Ministry of Industries and Production in promoting the turbine is important. The widespread application of renewable energy — both wind and solar power — in government buildings and urban and highway lighting instead of using fossil fuels and gas will help the country save the latter two resources for more productive uses. Besides, foreign investors may be keen to cooperate in Pakistan’s renewable energy sector. There is, therefore, nothing to lose and much to gain from redoubling efforts to develop our renewable energy resources.

Ms. Motala is right we must develop reuse able energy resources. The energy crisi can be ovecome by efforts and resolve of the peopl. We must also conserve energy bt using savers and other techniques. Re3newable energy must be employe to deter dependence on conventional resources. The depletion of resources must be arreste by wisely using lternative sources.r
When talking of renewable source of power we tend to forget that water also is a renewable source of energy. Demand for energy will reach 40,000 megawatts by 2025. Only by building mega dams can we hope to keep up with the energy demand. Dams will also give us water for agriculture for feeding the population which will also double by 2025. The dam storage capacity which was sufficient for 8 crore people when Tarbela dam was commissioned 38 years ago, cannot possibly be sufficient for 19 crore people today, and certainly not for double of this by 2025.
