Those all have significant hurdles to be overcome. Wind and solar both require significant infrastructure along. Nuclear has political issues and even without them the build out would/should be slow. Hydrogen is horribly inefficient. Hydro is very dependent on the terrain and has environmental impact problems.

I'm not saying they aren't part of the solution. But, we need to recognize the scale and complexity of the problem. Solving or at least weathering it will require multiple angles of attack, significant time, effort, engineering work and quite likely scientific advancement.
