Steel manufacturing is energy-intensive and hence a significant contributor of CO2 emissions. We project steel demand in India using regression analysis. A linear dynamic programming model has been developed to analyse the supply options and estimate the energy demand and CO2 emissions from the...

Aluminium manufacturing is highly energy-intensive and a large contributor of CO2. The emissions per tonne of aluminium manufacturing in India have been estimated. Demand for aluminium and associated CO2 emissions have been projected for the industry as a whole for the years 2001/02 and 2006/07....

The cost of irrigation water has been computed for two shallow-well, water-pumping windmill designs in India. An empirical relationship for variation of the overall efficiency of the windmills with wind-speed is established. Weibull parameters are computed for Indore, Madras and New Delhi and...

Indoor air pollution, caused by the combustion of four biofuels (fuelwood, dung cakes, agri-residue, and a mixture of fuelwood and dung cakes) in a traditional and an improved mud cookstove (Sugam-II), has been studied. The concentrations of three gaseous pollutants (CO, NO2, HCHO) were measured...

A simple framework for the estimation of fly ash utilisation potential in India is presented. It also enables estimation of associated resource savings. Results of some typical calculations are presented and described briefly.

The suitability of using biomass briquettes to substitute coal is debatable, as a substantial amount of energy is required for briquetting of biomass. In the present work, an attempt to evaluate the energetic viability of briquetting of agricultural residues compared with the energy embodied in...

A comparison of unit cost of water discharged using biomass gasifier based water pumping systems with two other commonly used conventional options, i.e. diesel engine pumpset and electric motor pumpset has been made. Results of some typical calculations have been presented and discussed.
