Solving for Energy | Sally Benson

TL;DR

The speaker discusses the urgent need to address climate change and the potential for zero emissions energy solutions to combat it.

Transcript

the other day I was teaching about 50 political journalists about climate change and they were absolutely shocked to learn that we could reach the 2 degree C climate threshold in 30 years or less now maybe 30 years sounds like a long time but in infrastructure years 30 30 years is just the blink of an eye think for example how long it took to rebui...
