Converting nascent fuel to electrical energy demands highly sophisticated technological conversion methods. Those being currently used are so inefficient that approximately 20- 30percent of actual electrical energy reaching the user. This small amount of electrical energy is again used in various appliances and machines to derive other energies such as light, heat, sound and mechanical efforts, a process in which more energy is lost. Thus, the final energy from which benefit is derived is in the range of only 10-25 per cent. One important feature of the Energy Conserva tion Act 2001 relates to benchmarking standards to simultaneously address: •!• E11ergy generating companies •!• T&D companies •!• Manufacturers •!• Consumers •!• R&D laboratories Efficiency improvement will also address environmental degradation issues such as mitigating C0 2 emissions. Any energy conservation efforts will however need that incentives are ex tended to manufacturers in high energy consuming sectors such as cement, aluminium and steel. An Indian consumer is normally not motivated to invest in high-priced energy efficient appliances. One way of going about organised sectors such as the government, semi-government, boards and corporations to buy appliances from approved retail shops or cooperatives, with the condition to submit utilisation certificates with supporting cash bills / vouchers. Alterna tively, approved retailers/cooperatives can sell energy efficient appliances on zero per cent interest through installments commensurate with the payback amount. Making extensive use of solar power in public buildings, and creating architectural desi~s with focus on light and heat requirement in both the domestic as well as public buildings sector.

It is estimated that more than 15 per cent of the energy consumed in the cement in the cement industry can be saved. Retrofitting energy saving systems is one of the most cost– effective methods. NCL Industries Limited runs a 275,000 TPA cemen t unit at Simhapuri in Nalgonda District of Andhra Pradesh. It currently consumes 122 kWh/ton of cement and 980 33
