Agreed YMU, but can I borrow that graph for a comparison with the total UK energy import / export situation over time?
As I was saying above, the only times in the last 40 odd years when we as a country have been able to actually pay off part of our national debt have been at points when we were briefly net energy exporters, thanks to the outputs from the North Sea.
We started increasing our national debt again in around 2002, just exactly at the point where we became a net energy importer again, and we're now on course to be left to import over half our energy requirements in around 5 years time.
As energy prices have sky rocketed since then, and are likely to continue to do so, the impact of this on the UK public accounts, and economy can only be multiplied.
Add these cold hard energy facts as a multiplier into the standard economic equations for recovery from recession and reducing deficits / paying off national debt via austerity measures, and it ought to be fairly clear exactly how much our politicians are screwing the country up.
Labour were utterly complacent about this, having no energy policy in place at all for the first 9 years of their time in power, and this lot are currently trying to out do them in the incompetence stakes on the energy planning side of things.
For avoidance of doubt, my major arguments with Falcon's view of things mostly isn't that the main thrust of what he's saying aren't possible, it's that he seems to put them across as being pretty much inevitable*, whereas I view them as being potential worst case scenario consequences of abject failures in government policy to address issues that are blatantly obvious for anyone with half a clue about the subject.
If things are portrayed as being inevitable, then it lets us and governments off the hook for their / our abject failure to take the serious actions on the issue that could have at least mitigated the worst impacts of the situation if not solved it entirely. The UK government are currently attempting to use a sticking plaster over a gaping wound in our economy, and we're in serious danger of bleeding out / losing a leg if they don't opt for major surgery in the not too distant future.
*and I have serious problems with his bottom line sustainable carrying capacity figures for the planet, and his over focus on oil vs total energy supply and a few other points.
