Air conditioners units in operation worldwide could jump from nearly 2 billion today to 5.6 billion by 2050

 

 As global temperatures, populations and incomes rise in countries like India and China, the number of AC units in operation worldwide could jump from nearly 2 billion today to 5.6 billion by 2050, according to the International Energy Agency.  

"By 2050, estimates say that just space cooling will account for 30% to 50% of peak electricity [load] in many countries. Today the average is 15%," said Riahi. "So you're going to have grid failures."
