Energy bills are set to rise because Britain will become more reliant on energy imports to fill a shortfall in domestic production, the industry watchdog has warned. Ofgem said supplies are on a "rollercoaster" and heading "downhill fast".
Ofgem Chief Executive Alistair Buchanan told ITV News consumers need to start looking at their bills after he warned that energy supplies are on a "rollercoaster":
Our increasing reliance on gas leaves the UK more reliant on an energy supply from a very dangerous part of the world.
So what is behind the new urgency in the warnings about keeping the lights on?
The boss of energy regulator Ofgem has warned that the looming shutdown of several coal power plants will raise energy bills further.
