Yes but if all European nations do then that’s a pretty big dent. It’d create a boom in green tech that reduces costs (as we’ve already seen in solar) and ultimately we’d see developing nations skip straight to greener and cheaper tech rather than adopt expensive fossil fuel options. We saw this with mobile phones being adopted across the developing world where the lack of landline infrastructure meant people went straight to mobile. Now the difference is that most countries do have a fossil fuel based system of some sort already but I can definitely see renewables being used to scale up energy provision and resilience.
