It is estimated that 1 billion air-conditioners will be installed over the next decade around the world.
According to The Economist, air-conditioning is a matter of life or death.
It makes hot places like Saudi Arabia comfortable to live in.
In France, they made airconditioning mandatory in old-people’s homes after the heat killed 17,000 people in 2003.
But a study in Denmark found out that air-conditioners can cause problems. They use electricity and increase the emission of greenhouse gases.
So how do you solve this problem?
Greenhouse gases, The Economist explains, can be reduced if airconditioning units are made more energy efficient.
Maybe it’s time to check if your air-conditioning unit and help the planet.
