The world could face a "Cold Crack"
The climate is heating up, the challenge of cooling buildings is therefore major ... today we found ourselves in a vicious circle, Because the number of air conditioners in the world could increase from 1.6 billion today to 5.6 billion in 2050, or 10 air conditioners sold per second for 30 years!
Machines that will require resources to be produced and then consume electricity to operate. So much so that their needs will simply be the main driver of electricity demand for the next 30 years, and to power them will require production capacity equivalent to that of the United States, the European Union and Japan together.
To date, air conditioners already installed around the world use 1/5th of the energy of buildings, or 10% of the world’s electricity.  
Generalized access to air conditioning will have a significant impact on the global energy demand of the countries concerned, putting pressure on the electricity networks.
How to avoid this absurd situation where it will be necessary to build additional power stations to supply the cooling units?
