02: Cool solutions to a warming planet
Radhika manages the Global Cooling Prize and in this, the second episode of our second season, she talks about the incredibly troubling position the planet is in due to inefficient room air conditioners.
If you haven't stopped to think about your room air conditioner and its potential impact on a warming planet – here’s some context to help frame the global cooling problem:
- By 2030, over half of the world’s population will live in hot climates – many will experience increased exposure to potentially dangerous heat conditions
- Due to this increasing risk of heat stress, residential cooling demand across the globe is expected to almost quadruple
- To meet this demand, approximately 4.5 billion room air conditioners will be in use by 2050 – compared to the 1.2 billion in use today
- Currently, room air conditioners being commonly sold in the market are extremely energy inefficient. Only 14 per cent of maximum theoretical efficiency has been reached by today’s most advanced room air conditioners, with the majority of models reaching only eight per cent efficiency
This is a power crisis, an energy crisis, a climate crisis and an economic crisis and it will affect global productivity, health, and losses in GDP.
