The wrong sort of argument
Lewis, Lewis, Lewis!
While I admire your passion and you may even be right, you won't win any arguments. The problem is that to get public opinion in favour of an idea, that public has to lose something they value. It's no good promising "jam tomorrow" or "a bad thing might/will happen". The various financial crises we've been enduring for the past 3 years shows that nobody is prepared to suffer now for advantages later. Not us, not the greeks: nobody.
if we are going to blame the government (and to be fair, it's parties on all sides, colours, beliefs and abilities) for short-term policies, bowing to NIMBY-ism, prevarications or even carelessness it's because these are the politicians that we have decided to give power to. They reflect us.
Sadly the only way to get some action on energy security is for the country to experience its loss. Not to have the price screwed forever upwards like the mythically boiled frog. It needs a SHOCK to kick-start a new initiative, not a gradual phasing in or gradual price increases. However when that shock happens, just like it did for the economy it will (no doubt) be unexpected, severe and blaming all the wrong people for it's causes (and therefore looking at all the wrong remedies for its solution).
When that happens you may well have a schadenfreude moment, for all the good it will do. Though I'd advise you to have all your evidence printed out and a torch handy, as the lights will be off and the computers won't work.
