No other technology - not solar, not wind, not whatever green scheme you dream up - can produce electricity on a large scale.
This is not true. Both solar and wind can scale as far as you want. There are few places where at least one is not an option, and both can generate way more energy than the world uses (particularly solar).
Given the current construction times for nuclear reactors in the West which approaches a couple of decades from proposal to first production, nuclear is likely to be too little, too late. But by all means, build some nuclear power plants. Particularly if you are in a country which is fucked when it comes to solar and wind, like England.
