Solarpunk

I get the sentiment in here, but the poster is missing an important point: there is a reason some group of lunatics (called the TSO or Transport System Operator or in some cases other power producers) are willing to pay for people to consume electricity when there is too much of it; They are not doing it for the sake of being lunatics, the electrical system cannot handle over or underproduction. Perfectly balanced (as all things should be) is the only way the grid can exist.

The production capacity in the grid needs to be as big as peak demand. The challenge we face with most renewables is that their production is fickly. For a true solarpunk future, the demand side needs to be flexible and there need to be energy storages to balance the production (and still, in cold and dark environments other solutions are needed).

In off-grid, local usages we usually see this happen naturally. We conserve power on cloudy low-wind days to make sure we have enough to run during the night (demand side flexibility) and almost everyone has a suitably sized battery to last the night. The price variability is one (flawed) mechanism to make this happen on a grid or bidding zone level.
