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.

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 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.

An attempt for the techno-economic evaluation of biogas-based water pumping systems in India has been made in the present work. The potential reduction in the amount of CO2 released in the atmosphere due to the use of the biogas-based water pumping systems has also been taken into account in the...

The challenges of providing electricity to rural households are manifold. Ever increasing demand-supply gap, crumbling electricity transmission and distribution infrastructure, high cost of delivered electricity are a few of these. Use of renewable energy technologies for meeting basic energy...
