| Summary/Abstract |
End-use electricity efficiency improvements offer an inexpensive way to reduce power shortages. The present study estimates the potential of demand-side management efficiency improvement targeted at (1) short-term efficiency improvement (agricultural pump rectification) that can provide immediate relief, and (2) long-term efficiency improvement (appliance standards such as AC and refrigerator, new agricultural pump purchase and pump replacement) for Gujarat state in India. The methodology includes the calculation of cost of conserved energy for each technology, which works out to be (-1.18) US$ cents/kW h for new agriculture pump sets, 1.03 US$ cents/kW h for refrigerators and 5.21 US$ cents/kW h for air conditioners. The price of power varies around 1.13 US$ cents to 12.1 cents/kW h in Gujarat. The annual energy savings from the selected energy-efficient technologies are approximately 8767 GW h over a period of 10 yr, while the estimated peak power savings are about 1814 MW, large enough to eliminate one-fourth of the state's electricity shortages. Also, the estimated CO2 emissions savings are about 7715 Giga grams (Gg) from implementation of the selected energy efficiency measures over a period of 10 yr.

| Summary/Abstract |
Electricity production causes unintended impacts. Their exclusion by the market leads to suboptimal resource allocations. Monetizing and internalizing of external costs, though challenging and debatable, leads to a better allocation of economic resources and welfare. In this paper, a life-cycle analysis (LCA) on the production of electricity from conventional coal based electricity generation system has been performed in order to examine the environmental impacts of coal based electricity generating systems in the twin-city of Ahmedabad and Gandhinagar in western India. By using dose-response functions, we make an attempt to estimate the damages to human health, crops, and building materials resulting from the operation of coal power plants and its associated mines. Further, we use geographic information system to account for spatially dependent data. Finally, monetary values have been assigned to estimate the damage to human health, crops and building materials. This study reveals that the health as well as on non-health impacts of air pollution resulting from coal based electricity generation may not be ignored both in absolute as well as economic value terms.
