Despite the (deliberately) controversial tone of my first post, I have a lot of sympathy with what Linda says - renewables are never going to fill the 'energy gap' and a degree of self-sufficiency in energy supply is going to be essential as the world's demand for LNG and oil begins to outstrip supply.
The main worry is that some government (of whatever colour) is simply going to take an opportunistic, short term view of this new resource and 'flog the family silver' in the same way as was done with North Sea oil/gas in the 1980s - rather than doing as the Norwegians did and ekeing out a finite reserve to benefit their country for a lifetime.
And, of course, the real answer is to build nuclear as fast as is humanly possible .... < and anyone who says otherwise better be prepared to live in a cold, dark country from around 2020 onwards >
