Who should I get to supply my energy?
Whilst there are many comparison sites & price guides out there, there are far fewer resources for people who care about the environment. However, the general consensus at the present time seems to be that British Gas are the 'greenest' major providers, so if you're considering getting a new boiler or switching supplier, it could be well worth the planet's while if you used them for gas and electricity.
Their website contains plenty of advice on how to save energy, including information on solar panels and energy-saving boilers, and their Zero Carbon scheme claims to eradicate your carbon footprint entirely. When you sign up to it they also subscribe you to a newsletter detailing various ways to save energy. BG are also committed (to the tune of over £700 million so far!) to investing in green fuel alternatives.
However – there are greener companies out there; like
Good Energy. 100% of all their energy comes from renewable resources; solar power , wave, small scale hydro and wind. That's not to say they're the cheapest out these – quite far from it. For a business to sign up to Good Energy, there's a cost 17p a day before you even use any electricity. But for absolute peace of mind, they're one of the best companies to go for, as none of the fuels mentioned above create ANY Co2 emission.
If you're not interested in how green your supplier is, and just want the cheapest – then I'm afraid there's no one single company that has 'the cheapest'. It depends on a number of factors; where you live and how much energy you use being the two main ones. There's also the type of energy you use; whether your heating is run on
gas and electric or
dual fuel – all the major supplies (like British Gas) have an assortment of price plans to cater for this variation.

Happy heating!
