A simple framework for quantifying the monetary benefits of replacing a traditional biomass cookstove by an improved cookstove is presented. Sample calculations for Bangladesh conditions are presented and discussed briefly.

The indoor monitoring of carbon monoxide and suspended particulate matter (SPM) was carried out for a 1-h fuelwood combustion period in traditional and portable metallic cookstoves. The benzo (a) pyrene content present in the SPM was also determined. The monitoring was carried out at three...

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...

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...

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.
