The move comes following dramatic new figures that have been revealed by the Liberal Democrats showing that Bristol is doing better than the country as a whole in keeping down emissions of the gases that cause climate change, but is still emitting nearly three times as much carbon dioxide as the global average.
Stephen Williams said "With a population of 391,500 Bristol is emitting 2,448,200 tonnes of carbon each year on the latest official figures. This puts us at 6.3 tonnes of carbon per person per year, 32.6% less than the UK average of 9.3 tonnes per person, but still far higher than the global average of around 2.5 tonnes per person.
"This is a creditable record, but we need to go further to get down to a sustainable level that will stop climate chaos, rising sea levels and storms. That is why I have switched my energy supplier and I would urge others to do the same.
"All the main political parties now agree that we have to tackle climate change, but only the Liberal Democrats are leading by example and have put forward firm plans to help us change our behaviour through tax incentives."
Good Energy Chief Executive, Juliet Davenport, welcomed Stephen Williams by saying "It's great Stephen is putting his words into actions by signing up his home and office to Good Energy. As the supplier of 100% renewable electricity in the UK, we are dedicated to providing solutions to climate change. The Liberal Democrats are demonstrating their environmental leadership with their proposals on green taxes and environmental policy, and its great to see them act on the ground as well as in Westminster."
Also welcoming Stephen Williams to the company is Jackson Moulding of the Ashley Vale Self Build project. Good Energy have worked closely with the Ashley Vale Action Group, who are a community group in inner-city Bristol who formed a not-for-profit company to take control of the re-development of a brown-field site in their neighbourhood.
They believe that building developments should be community-based, environmentally-sensitive initiatives, rather than profit-driven commercial enterprises. In May 2001, they succeeded in buying a development site in St Werburghs in order to create innovative and sustainable self-build housing and office, workshop and community space.
The solar panels on the site now supply Good Energy with renewable electricity as well as helping to power the homes on the site.
