Space cooling eats up 10% of global electricity use, and by 2050 total energy consumed could triple as ownership takes off in developing countries. It’s why the Global Cooling Prize was launched to find AC designs that will have an 80% lower climate impact, explains John Matson at RMI. The two main design goals were to reduce electricity demand, and use refrigerants with lower global warming potential (GWP) than traditional refrigerant gases. The … [Read more...]
