Geothrenal is limited geographically. Iceland has plenty but a tiny population. California has a lot but it’s largely tapped out and what we do have is sufficient only for the communities nearby to the plants. Your hypothetical biomass burning coal plants are still that: hypothetical. If they work at scale, add that to the list. Damming up rivers has its own problems, but this is largely moot: the majority of lakes in California are dam lakes and damn near every river with good capacity in the State is already dammed up. Tidal power is likely to have other environmental concerns. If mitigating these concerns still makes it cheaper than nuclear plants, fine, but I’m not going to support the installation of any new tech that screws with coastal ecosystems the same way we screwed up prior river and lake ecosystems.
