The role of electricity in sustainable development

Current projections estimating world population growth read in conjunction with corresponding projections of increased,world energy consumption, point to electricity as the cleaner fuel of the future. especially because of its high efficiency and low levels of pollution. Due mostly to the fact that the electrical end-use devices are considerably more efficient than those using other forms of energy. most developed countries show decreasing curves of energy intensity as technologies become more sophisticated and shift over to increased reliance on electricity. II is therefore argued in this article that a gradual shift away from fossil fuels to electricity is a promising possibility to bring down global air pollution and emissions of greenhouse gases to acceptable levels. Examples are given of greater efficiency achieved by electrification. Overall gains in energy efficiency from the change over from fossil fuels to electricity. are possible even in situations where the electricity is generated by fossil fuel combustion. despite the loss of primary energy in the conversion process. The article also presents electricity generating projects designed for developing countries and countries with economies iri transition. The generation of electricity from the combustion of renewable sources (biomass waste). fossil/fuels, and other innovative methods are outlined. (C) 1997 United Nations.
