Energy and money are not the same.

I can use bitcoin just as easily to buy a loaf of bread whether that requires 5,000 sats, 50,000 sats, or 5 sats.

In other words, scarcity of money does not make the money less useful (as money) to me.

Energy is different. Scarcity makes an energy less useful. A diesel truck will only run on diesel fuel. If some of the demand for diesel is due to power plants running on diesel (even if just a peaker plant) generation of power from other sources can reduce the operation of those diesel power plants, which then results in diesel being more affordable and thus more useful for transportation.

Wind and solar do have utility (pun intended). Whether they are competitive as the alternatives (natural gas, hydroelectric generation), ... that's debatable yet today. But progress towards harvesting nature's energy at greater efficiency and lower cost of production (i.e., resources needed for it, including capital expense) will benefit us all.

So yes, I want wind power, solar power, hydro, geothermal, coal, natural gas, ... and safe and competitively priced nuclear power (which I'm not yet convinced exists, at least not at a cost that considers the entire life span through decommissioning).

I want them all battling it out. Without government subsidies. Like you mention, bitcoin mining essentially now becomes that method to subsidize energy production that might not have been viable previously.
