GDP, jobs and energy security. Whether or not bills come down in price is a red herring pushed by opponents desperately seeking a way to dis the industry. Gas will be traded on the international market meaning that we would be selling gas abroad at prices which the markets dictate.
As it stands bills are set to increase massively because of the green obsession with fantastic subsidies going to wind and solar factories which we all know produce little energy - in fact in the main do quite the opposite because of the way the grid works.
For those still under the delusion that renewable energy is the answer once again I draw your attention to this. Take note of the wind meter on the right and check out this months output.

Personally I'd go for coal. A beautiful and God given rock without which we would still be rubbing sticks together.
I love it and would eat it for breakfast if it were edible.
