Air conditioning already accounts for 9% of electricity consumed globally, and that demand is set to grow substantially in the coming decades. While many living in hot climates need it just for comfort, others see it as a status symbol – their ticket to the middle class. For businesses, it may underpin worker productivity. BNEF's Seb Henbest and Matthias Kimmel join the show today to discuss the effect of the ever-louder hum of aircon units on global electricity demand.  Switched On is hosted this week by Head of Business Development Dana Perkins.
