People should understand that it is all an energy problem, regardless of how that energy is currently delivered. Transportation can be (and, of course, is being electrified), most industrial processes and agriculture currently use fossil fuels as inputs because its the cheapest source of input.

For example, nitrogen fixation for fertilizer currently uses natural gas almost entirely for the source of hydrogen. Vastly cheaper energy means it would make much more sense to switch this to electricity, https://www.frontiersin.org/articles/10.3389/fenrg.2021.5808....

But I agree with your sentiment, there are a lot of engineering details to consider before one can shout "free energy".
