@vonKordke@mastodon.com.pl @bascule@mas.to you absolute can by adding batteries and more high voltage lines to interconnect more grids and minimize the affect of variability at a local level. They build industrial solar where its very bright, and they build wind turbines where its nearly perpetually windy. As long as those sources are connected to more grids, we are fine.
For other sources, nuclear can be fine but very slow to build so it should be a backup option and not a primary one. Hydro is a great baseload right now, but more dams is tricky. Geothermal looks better than nuclear, if nascent, and natgas generators can be converted to run on green hydrogen made with solar/wind that would otherwise be load shedding.
Mix all of the generation of the above with an equally important change in consumption: heat pumps for HVAC and hot water, induction cooktops, and electric vehicles, and you can satisfy all energy needs with much, much less overall electrical generation than the mass total of electrical/fossil we use now.
All it takes is building things that we can build today.
