The challenge isn't about producing electricity, but providing it when needed. In most nations "providing it when needed" was equivalent to "producing it when needed" because, then, the sole way to realistically store enough electricity (hydro dams) weren't a solution due to inadequate local features (geography). It isn't true anymore, as we now can store huge amounts of electricity in batteries (mainly in vehicles), as hydrogen... "Producing it when needed" was equivalent to "generating electricity in a fully controllable manner, using a managed stock of fuel in order to adjust production (especially: bumping it up whenever consumption rises)" because there was no real way to balance things on a large scale by massively benefiting from a remote electricity-generating equipment because transporting electricity over long distances was expensive and impractical (too much line losses). This isn't true anymore, thanks to (U)HVDC ( https://en.wikipedia.org/wiki/List_of_HVDC_projects https://en.wikipedia.org/wiki/List_of_HVDC_projects ), enabling continental-sized grids reducing the effects of wind and solar intermittency ( https://www.imperial.ac.uk/news/180592/european-cooperation-could-provide-more-stable/ https://www.imperial.ac.uk/news/180592/european-cooperation-... )
