Cooling vehicle cabins int he US uses around 27bn/l gasoline annually, a projected 8.7 billion/l in Europe, and 3 billion/l in Japan (assuming all vehicles have air conditioners). The amount of fuel in the US alone is equivalent to 10% US imported crude oil. Vehicle air-conditioning systems can increase the fuel consumption of a conventional vehicle by 28%; in hybrid electric vehicles by more than 100%. A 12 deg C reduction in the peak cabin temperature of a vehicle can reduce fuel used for air-conditioning by 50%. Solar reflective glazings play a critical role in this, as described here.
