Sure - there's plenty of investment in both off-shore and on-shore wind generation in the UK (this gives a pretty good idea of the scale), but it doesn't change the fact that wind power cannot at present - in lieu of radical developments in energy storage, or demand modulation - provide reliable base-load. Wind-farms - even when offshore generate plenty of objections.
It's disappointing that there have not been more offshore tidal energy schemes, since these could be an entirely reliable energy source. The usual excuse offered is that whilst there are plenty of prototype devices, none of them are considered mature enough for large-scale investment.
Rather than increasing the amount of nuclear energy the in the UK, the proposed reactors are replacements for existing nuclear generation capacity that is reaching the end its life. What is perhaps interesting is that economics are starting to look very favourable for Nuclear generation right now - renewable generation is not cheap.
