Of course it is relevant, Gromit.
Domestic production is ever-declining.
2009 45% of our natural gas was imported
2013 Highest ever amount of gas was imported - 14.7 bcm between Jan and March alone.
2019 Projected imports of natural gas will be at 70%
Of that imported gas,75% comes through pipelines from Norway, Belgium and Holland. The rest we get in liquified form via tankers.
And we have to buy that imported gas via supply contracts in the global marketplace - and that is a very volatile market, subject to change at a moments notice. The supply contracts that energy companies sign reflect that, and producers/exporters of gas will look to maximise their return.
So purely from a negotiating perspective, it would make far more sense if the UK maintained greater fuel reserves, making them less reliant on such a volatile marketplace.
"The International Energy Agency (IEA) expects demand for gas consumption in emerging economies to overtake mature economies by 2030. The UK Government has warned that remaining heavily dependent on imported fossil fuels could expose the UK to the risk of supply shortage and price volatility"
And then you have the margins for keeping the lights on. It was claimed that at one point during the cold spell last winter, the UK was "just hours" away from using up its stocks of gas.
Is such short termism in the form of gas supply a sign of good governance? Allowing ourselves to become hostages to the gas market - is that a good thing? I do not think so.
