"Free" (as in, your taxes) energy for all is very likely to entirely wreck the economy.
Not to mention there are costs involved with maintenance which make that energy not free. Even ignoring the huge debt incurred by implementing such a solution, who will pay for the maintenance? Our taxes again?
What are the benefits of not paying energy? What innovation is not happening because the pesky electricity has a cost?
Most likely it would just become the country of choice to run computations (whether meaningful research or pointless crypto mining) - if we ignore the gargantuan tax rate this country will have.
Being independent is valuable, that's why I think everybody should source their electricity independently (eg. solar)
Probably the last big holdout for hydrocarbons will be aviation, but anywhere LH2 airframes start to move in, the old stuff will be wholly unable to compete. Transitioning the whole fleet will take a long time, though.
Something I've been thinking about for a while: the best course of action to secure a nation is to build out renewables until the need for external fossil fuels is zero. Even if that means using renewables to make fossil fuels via a process like Fischer–Tropsch as a stop gap.
I also think it would be advantageous to start thinking about how to drive the cost of generation and distribution down until electricity is free or nearly free. This might sound utopian but imagine how secure and prosperous a society could be if energy was super cheap or free? We are moving towards an electrified future and at some point we will have to heat homes and charge cars with electric that will place significant demand on an ageing grid.
