BINGO!
If you have something that will buy any left over or unusable stock of product X, the production of X becomes less risky and easier to invest in. This isn't hard. Bitcoin incentivizes energy production and innovation. If you want that energy to be green, bitcoin is still more than willing to buy it from you. Lowering the risk of innovation in the space is obviously good for green energy.
Your arguments work just as well for reducing risk for investing in "marginal" fossil fuel sources.
Bitcoin does nothing to alter or effect other incentives or disincentives on energy production.
Assuming prices are equivalent, it's net neutral on production mix. However, we've been told renewable energy is cheaper! Therefore it accelerates its adoption.
