I know it’s wintertime for many of you, but that doesn’t mean we can ignore how cities around the world are heating up and how air conditioning is a growing contributor to climate change. Air conditioning is responsible for about 4% of global greenhouse gas emissions. Today, about 20% of electricity used in buildings and about 10% of global electricity use comes from operating air conditioners. With cities heating up and more people able to afford this technology, air conditioning emissions are expected to double by 2030 and triple by 2050.To understand this problem and some promising solutions, I sat down with Matthias Roth and Ran Roth. Matthias is a Professor of Geography and Urban Climatology at the University of Singapore. Ran is the Founder of Sensibo, a startup that’s using data and AI to improve the efficiency of air conditioners around the world. No family relation between the two Roths, but a shared interest in how cities are heating up and what we can do about it. We talk about urban heat islands, how cities are responding, the growth of air conditioning, Sensibo’s solution to making them smarter and more efficient, what else needs attention, and much more. Wherever you are, warm up and stay cool with this episode.
