I think 100% in general is a vague notion. 100% of what? Current demand would be mostly excluding things that in the future would be included. Things like heating houses (mostly gas currently in a lot of countries). Or powering the things you mention. Or creating vast amounts of hydrogen. Or powering most forms of road transport. All of those things are starting to happen. Carbon neutrality involves most of those things happening on a very large scale. Our current electricity demand is a small portion of that overall future demand.
