Energy supply security is key to the clean energy transition, but models sometimes overlook it.
Our new paper, in @cp-iscience.bsky.social with @empa-materials.bsky.social colleagues, introduces the ESS Pyramid, a hierarchical framework to assess and strengthen security in future energy systems 🔌💡

How much emissions do EVs cause through the electricity they consume? How do we know?
Our paper shows that frequently used metrics *over*-estimate EV emissions.

Yes, my favourite energy transition stat: Chinese sales of oil-powered cars peaked in **2017**🤯
I heard @cleanpowerdave.bsky.social mention on the @volts.wtf podcast that "sales of oil-powered cars peaked back in 2017. They've been falling for almost eight years now. It's insane", so I've updated my data back to 2015 to show this.
