If only that pesky sun stayed up 24 hours a day...

I think rather than looking to install enough solar panels to mine on 100% renewable energy, people should think of mining on renewable energy as a way to elevate their financial benefit from overproduction of electricity.  For example, there are a lot of solar systems in use throughout the country that overproduce electricity during certain hours of the day.  Currently, many of these producers get compensated very poorly for energy they add to the grid.  Mining crypto is a good way to take that excess energy and profit at a much higher rate.  Additionally, at night it can save wasting energy on heating and instead put that toward generating crypto assets.

So instead of looking at mining as a problem that needs to be solved with a ton of solar panels, look at it as a solution for how to benefit from excess energy production.
