Let's leave politics out of this. Talking on a purely factual level the future energy security of this country does not lie with fossil fuels. Poisoning the masses in fracking our land does nobody but the exchequer and big oil & gas a favour.
We need a way to harness the natural energy we have en masse in this country, which would mean a more intelligent National Grid, quite simply. A way of storing energy and releasing it during peak demand is the way of the future and one we must adopt in the next 50 years or so. Wether that's done on a national level, or with individual properties creating and storing their own energy remains to be seen (I like the idea of small grids in communities or individual properties storing energy in battery banks, for example). There is no one magical solution, nor should we plunge our energy future with any one technology. A mix of wind, wave and solar is where to start - if that means more wind farms and solar panels then so be it - i'll be happy to see a wind turbine on a hill to achieve that.
Side note: Denmark (as an example) already have windfarms providing roughly 50% of the countries energy. Scotland could be well on it's way to doing that too:
