A lot of hydroelectric depends on snow pack and glacier runoff that is being adversely affected by global warming. Solar and wind are the only robust hedges against a warm up that might ultimately severely curtail river flow. We have a lot of uranium and nuclear is fairly renewable at least in the span of a few centuries. The waste issue is a problem.
