I work in the market, and the report on BBC Breakfast was close, but not quite spot on. Another post on this board suggests they're sensationalist and he was right. I like Declan though, he seems a canny lad.
Stupidly, the cost of wholesale gas is linked to the price of oil - so the recent increases in the oil market have had a rather alarming effect on the gas wholesale market. A large portion of Britain's electricity is from gas power stations so increases in oil are like a line of dominoes straight to the consumer's pocket.
This winter a new pipe between the UK and Norway opens which is going to make some difference to the price of gas and therefore electricity. It also means we no longer have such a huge reliance on the Interconnector pipe from Belgium. Add to that a slight drop in oil prices (yay petrol) and we're moving in the right direction.
Part of the blame (not a lot, but some) can also be apportioned to the slow speed of liberalisation across Europe - national suppliers on the continent can see that Britain is starting to rely more and more on imports and they're taking advantage of it before competition opens in their own country (there's more to it, but if you thought the last sentence was boring, it gets worse).
The biggest problem (and some don't see it that way) is that the people supplying your gas and electricity are companies - they exist to make a profit and they exist to make the shareholders, not the customers, smile. Look around, like someone said before, the vast majority of people can make a saving - the number of people who are with the most expensive gas and electricity supplier (British Gas) is astounding.
With regards renewable energy, you can find information on how companies mix their production here (info for the stattos!):

If you're having problems with your gas and/or elecctricity supplier, there are ways you can get help. Firstly, speak to your supplier - most people working for suppliers may have their hands tied with regards what help they can give, but they deal with large bills every day - it can't hurt to give them a quick call.
Failing that, try the watchdog, Energywatch. They have some helpful PDFs you can download, a Knowledge Base for simple generic queries and they can, if the company hasn't helped you, take up your complaint on your behalf. They have complaints numbers and all sorts on there. If you really care about your energy bills, do yourself a favour and go have a browse of their website:

Errrrr, sorry for the long post.
