In @TransitionShow Ep. 273, Tom Brown @nworbmot shares a new model which shows that by 2030, solar and batteries could supply 90% of electricity to 80% of the global population for less than €80/MWh. It would not only be cost-effective, but also likely cheaper than gas. https://xenetwork.org/ets/episodes/episode-273-can-solar-and-batteries-power-the-world/
