HARYANATOINTRODUCESOLAR PUMPS The Hindu, 13 April 02 The Haryana government has decided to introduce a scheme for setting up 200 solar pumps of 1800watt photovolatic panel at a cost of Rs 90 million for pumping water, catering to the growing demand for electricity and reducing the usage of diesel in the agriculture sector. These pumps would be made available to the farmers for agriculture and rel ated activities such as minor irrigation, cash crops, horticulture, fish farming, etc on first come first served basis of the selected blocks where water table is below eight metres depth. Only one pump set would be provided to each farmer. Courtesy: TERI Newswire, 1-15 Apr 02, P27..

Smidth's Indian centre, Fuller India Limited, has recently received two orders for plant upgrades that include retrofitting of CIS-MFR grate coolers. Suvarana Cement operating a 300 tpd SP kiln has placed an order to upgrade capacity to 900 tpd. The modifications comprise preheater conversion to 5 stage ILC, LP cyclones for the existing 2 nd and 4 1 h stages, a CIS- MFR (Controlled Impact System-Mechanical Flow Regula~ion) grate cooler retrofit and a fuel dosing. System for the calciner. These modifications of the pyroprocessing systemwill not only bring about a capacity increase but also lead to thermal savings of 100 kcal / kg clinker.

Had American continued to use energy as intensively as in 1970, the US would have consumed about 177 quadrillion Btu of energy in 2000, compared to about 99 quadrillion Btu actually consumed. Improved energy efficiency is the result of many decisions, including those of individual consumers as well as manufacturers and government can also promote energy efficiency and conservation through programmes such as the Energy Star programme, and search for more innovative technologies that improve efficiency and conservation through research and development. Gains in energy efficiency over the last three decades were built on a combination of technological improvements, better management practices, and learning to put these technologies and practices to their best use. In many areas, the results have been quit e impressive. New home refrigerators use about one-third of the electricity they used in 1972. Compact fluorescent lights use about 25 per cent of the electricity of the incandescent bulbs they replace. Automobiles use roughly 60 per cent of the gasoline they did in 1972 per mile driven. These individual technological improvements have resulted in significant reductions in energy use. Advanced sensors and controls enable more efficient operation of buildings and factories, and allow equipment and lights to be turned off or dimmed when not in use. Hybrid vehicles use power electronics and battery storage to get more out of every gallon of gasoline consumed, - . .
