Renewable Sources of Energy: Prospects and Issues

Energy Demand

Sourcewise energy demand shows that the bio resources constitute a major energy source (84% - Dimestic, household industries and small scale industries), followed by electricity (irrigation in Agriculture), Kerosene (lighting etc.)

Firewood as Energy Source

Status of Bio Resource availability and demand for Kolar:

The ratio of productivity and fuelwood demand is computed to get an idea of level of bioresource availability in Kolar taluk. Total bioresource available from various resources is about 3058 lakh kWh per year. The availability to demand ratio ranges from 0.33 (if fuelwood demand is taken as 2.5 kg/person/day) to 0.64 (if fuelwood demand is taken as 1.3 kg/person/day). The ratio being less than one indicates that there is bio resource scarcity.
