What is the value of biomass 🥬 in future energy systems 🔌💡💨😎?
TL;DR: it's more important to provide renewable carbon than energy, thus saving on expensive direct air capture
Featuring PyPSA-Eur with biomass extensions and some fun near-optimal analysis!

Solar capacity additions are continuing to scale up much faster than most people expected ☀️
Our analysis suggest that close to 600GW could be installed globally in 2024.
To put that in perspective, that's 3x the total existing solar capacity in the US in 2023 – all installed in one year.

"Why are electricity prices so high if renewables break generation records and are so cheap?" I have been asked.
The main reason: Gas still sets the price 63% of the time in wholesale electricity markets in EU27 & >90% in some countries.

Tesla thinks it can out-compete others without the $7500 tax credit. This will be hugely damaging to other automakers producing EVs, most of them in GOP districts (in GA, TN, IN, NC, SC etc). Will House reps let Trump cut off their constituents' nose to spite Biden's face & further enrich Elon? 🔌💡

Ending the credit could have grave implications for an already stalling EV transition.
