700 million ACs will be installed in world soon

A recent report projects that the world is set to install 700 million air conditioners by 2030, and 1.6 billion of them by 2050. In terms of electricity use and greenhouse gas emissions, that's like adding several new countries to the world. The biggest country for air conditioning growth, and associated greenhouse gas emissions, is projected to be India. The country experiences not only extremely hot temperatures, but has relatively little air conditioning installed so far - indeed, in coming years India hopes to first bring electricity itself to several hundred million people.
