LIGHTS went out in Exeter as hundreds of people across the city took part in the Big Switch Off.

Nearly 1,000 city residents joined one billion people around the world in switching off electrical appliances for one hour, in a symbolic event to raise awareness for climate change. To drum up support for the global initiative, Exeter City Council hosted a special event in Princesshay on Saturday, featuring a visit from eco campaigner Brigit Strawbridge's Big Green Bus.

The double-decker was filled with interactive information about how to use less energy and be more environmentally friendly.

"I started The Big Green Bus charity because I think people don't realise how fun, easy, inexpensive and healthy it is being green," said Ms Strawbridge.

"We want to demystify all the terms out there. We tell people not to worry if they are not green, but to come in and have a look and we will show them something they can do to save money or be healthy. We have something for everyone."

The bus was packed with information on how to be green, including natural cleaning products, energy saving tips and alternative sources, composting, and even flowers to plant to attract bees.

There was a puppet show in the afternoon for children and TV presenter Dick Strawbridge gave a talk on renewable energy.

The bus itself is covered in non-toxic paint, the wood floors come from Herefordshire, the pillows are all hemp-covered and the engine will soon run on recycled vegetable oil.

"The volunteers and I were rushed off our feet all day which means that people in Exeter are interested in the environment," said Ms Strawbridge.

"I think the public are desperate for information and when it is hands-on it makes it easier to grasp." Kathryn Lamble, environmental co-ordinator for Exeter City Council, who organised the event, said: "I think the day was a fantastic success. Over 200 people signed up for the Big Switch Off on the day, in addition to the 600 who had already committed."

One Exeter resident who signed up was Ruth Gibson, 60, from Stoke Hill.

She said: "There is a lot of waste and I don't believe in having lights on unless you need them.

"I also learned from the bus that I can buy energy efficient light bulbs for our dimmer switch which I didn't think was possible."

Jenny Hubbard, 24, a jeweller from Exeter, said: "I just picked up some information about car efficiency so I will see if I can reduce that. In my house we will be switching off all the lights."

Exeter Cathedral joined in with the event by switching off its external floodlights between 8.30pm and 9.30pm on Saturday evening.
