Consumers who want to switch gas provider might be interested to hear that some British homes are now using energy generated from human waste.
A project at Didcot sewage works in Oxfordshire has started providing homes with low carbon cheap energy produced from natural waste products.
Biomethane gas from the site will generate enough power to supply up to 200 households and it is hoped that similar projects around the country will follow.
The joint venture between Thames Water, British Gas and Scotia Gas Networks treats sewage from 14 million people by using anaerobic digestion to yield biogas, before removing impurities and feeding the gas back into the grid.
Energy and climate change secretary Chris Huhne commented: "It's not every day that a secretary of state can announce that, for the first time ever in the UK, people can cook and heat their homes with gas generated from sewage."
He said it marks an "historic day" and the start of a "new era of renewable energy".
