Eight Global Cooling Prize finalists have been announced. (1) The prize was initiated by Rocky Mountain Institute (RMI); the Department of Science & Technology (DST), Government of India; and Mission Innovation, and is administered by RMI, Conservation X Labs, the Alliance for an Energy Efficient Economy (AEEE), and CEPT University. This is probably news to you. After all, we in the USA are being asked by our leaders to burn more coal, oil, and gas.
In other parts of the world where some degree of environmental rationality still exists, things are different. The Cooling Project goal is to to develop technology that will provide equivalent residential cooling for one fifth of the present power requirement. That improved efficiency can save up to 5,900 TWh/year in avoided demand in 2050, equal to 2X the annual generation of electricity within the EU, and it has the potential to potential to mitigate up to 0.5˚C of global warming by 2100.
Because our Legacy House is largely solar powered, our air-conditioning CO2 contribution is very low. We are probably doing better than the Cooling Project’s 2050 goals even today. Many people, particularly those in crowded urban environments or those lacking sufficient financial resources cannot go out and build solar houses. But if they can buy a window or house air-conditioner that is five times more efficient to run, that’s a winner from personal economic and global environmental perspectives.
