Current World Environment

Energy is the prime mover of economic growth and it is a wheel of modern economy. Future economic growth crucially depends on the long-term availability of energy, and cost of sources, availability, accessibility, and environmental friendly. India is a developing country and it needs more energy to accelerate the rate of development. India has the sixth position in the total energy consumption in the world. The energy resource is constant but energy consumption increases day by day. So each country requires more energy efficient equipment for the development and to save energy consumption. There are three ways for efficient energy conversion (a) Discover new energy resource (b) To minimize the energy losses (c) waste heat recovery. Here every human needs the energy for cook food. In India 74% population of India lives in villages and uses the conventional resources e.g. wood, cow dung and agriculture waste and available of bio-mass. So, I select rural area where mostly use bio-mass fuel, like wood and agriculture waste. The chulha (wood stove) use as a cook furnace for bio-mass in rural area. The traditional chulha give low thermal efficiency. In view of conservation of wood fuel and reduction of smoke from the kitchens of rural. In view of conservation of wood fuel and reduction of smoke from the kitchens of rural India, the Ministry of Non-conventional Energy Sources(MNES), Government of India, launched a National Programme on Improved Chullhas(NPIC) during 1984- 85. The NPIC measure traditional Chullhas have thermal efficiency is 8 to 10 percent but in my modified model, thermal efficiency has improved by 15 to 17 percent through extra supply of air. The thermal efficiency of modified chulha over the conventional chulha is 7 % to 9% more. In my modified model do not create pollution into environment due to complete combustion of fuel.
