Conservation of fossil fuels : Biodiesel, an emerging renewable source. -------- Leena Mehendale Principle Secretary, GAD, Maharashtra Twentieth Century saw an extensive use of fossil fuels all over the world, the innovations of hundreds and thousands of different uses for petroleum & natural gas has led to a significant increase in the need for fossil fuel in the world. A growing number of scientific researchers and political leaders have urged prompt conservation of fossil fuels by investing immediately in energy-efficient vehicles, machinery, and structures and by gradually shifting to alternative sources of energy. The reason most commonly given in support of fossil fuel conservation is that “Petroleum Resources are finite” and “the need to prevent future global climate change”. Most of these arguments say, “fossil fuels provide about 95 percent of the commercial energy used in the world economy”..... “Combustion of those fuels constitutes the largest source of emissions of cli...

Energy Security and Efficiency : Role of Bio-Gas. ----Leena Mehendale The question of energy security has become a major important agenda of the Government. With far higher cry for rural power, and high fluctuations in the international crude prices, the search for alternative fuels has become more urgent. A real boost to the solution for energy security however, lies in efficiency, rather than in higher supply. This aspect struck me greatly when recently I had a chance to look at the Integrated Energy Policy - a document prepared some two years back by Planning Commission of India. Let us look at some of the numbers mentioned therein. Our annual consumption of energy is nearly 450 Million Tonnes of Oil Equivalent (Mtoe). Out of this 110 Mtoe, that is, nearly one fourth, comes from non-commercial resources and only 340 Mtoe is commercial, in the form of electric power, Petroleum and Coal. The non-commercial sources are wood, biomass a...
