Unscramble the Blue Letters
Today’s air-conditioning is energy inefficient, depends on polluting refrigerants such as hydrofluorocarbons and many traditional cooling technologies waste heat. I’m sure you’ve had that experience of walking in an alley behind a convenience store and feeling that baslt of hot air on your face coming from the chillers inside.

And the demand for cooling is going up. The International Energy ancegy eittmesas that by 2050, today’s two billion air conditioners will have milipulted to more than 5.5 billion, and that by 2030, electricity demand for cooling buildings could jump by 50 percent. And think about this: most households in hot countries have not bhuogt their first air cnitnooiedr yet.

Original Text
Today’s air-conditioning is energy inefficient, depends on polluting refrigerants such as hydrofluorocarbons and many traditional cooling technologies waste heat. I’m sure you’ve had that experience of walking in an alley behind a convenience store and feeling that blast of hot air on your face coming from the chillers inside.
footnote
And the demand for cooling is going up. The International Energy Agency estimates that by 2050, today’s two billion air conditioners will have multiplied to more than 5.5 billion, and that by 2030, electricity demand for cooling buildings could jump by 50 percent. And think about this: most households in hot countries have not bought their first air conditioner yet.
