A recent analysis by Berkeley Lab on the importance of space cooling (air conditioning) in Mexico's energy landscape found that this use accounted for a summer electricity consumption increase by 30%; represents nine percent of total electricity use and produces a peak electricity demand of 7.5 GW. In addition, space cooling absorbs over $US 3 billion per year in energy bills and subsidies, generates 10 million metric tons of CO2 and creates a peak demand that is not well correlated to renewable resources. The research, titled "Mexico Cooling Fact Book" and led by Michael McNeil,... Read More
