Energy inefficiency can short circuit cooling India

More frequent and intense heat waves are expected with a rise in global temperatures due to climate change. In the last three decades, there have been 660 heat waves across India causing 12,273 deaths.

India, with currently low penetration levels of air conditioners (ACs), will likely require substantial cooling services to keep citizens healthy and productive. The India Cooling Action Plan projects the number of room air conditioners to become about four times in the next 10 years, and about 10 times in the next 20 years, making India the world’s largest energy user for cooling.

Scant data
Here lies a conundrum. Cooling will likely be at the forefront of India’s adaptation to climate change, but if cooling needs are met with inefficient ACs, it could be the bane of India’s mitigation efforts.

Indian homes will be an important site where this conundrum between cooling needs and potential emissions will play out. Despite its clear importance, the implications of an increase in residential cooling demand have not been carefully examined. Estimates of AC ownership and usage, the two factors which will determine the extent of future cooling demand, have little empirical backing. We know little about what cooling appliances people seek, and how and why people make their purchase decisions.

The pursuit of energy efficiency, too — for instance, who buys efficient technologies and why — remains underexplored.
