If you give people a limited amount of free power that's equivalent to giving them some free money. Which is fine and dandy but it's rather unrelated to how the grid works.
If you give people an unlimited amount of free power they're going to use it to mine cryptocurrency in a massively wasteful and expensive way.
I didn’t mean unlimited free power. I’d basically propose that the government would pay for as many solar panels as you can fit on your roof plus a battery in the garage or in a utility room. For apartments, the government would pay for some solar panels installed on a solar farm and you’d get a certain amount of energy for free covering the typical energy use of the size of your apartment. So we’re mainly just covering normal domestic usage. Of course if you’ve got anything spare you’re free to use that mining crypto but I don’t think that’s what the majority of households are really going to be doing.
