Why beans are more efficient than potatoes, and other eco-wonders

Some of us count the calories when it comes to food, but how many of us count the kilowatts too? Watch the quirky video above – there’s animation and a jolly opening piano melody too – and check out how Brighton-based Rob Smith, a resident of housing association Affinity Sutton, has developed a carbon calculator for the home.

For seven years, Smith has used an online programme to work out the carbon footprint of everything he uses in the home, so that he can find ways to keep reducing it. Beans on toast, he says, comes in at an energy efficient 95w to prepare, while oven-baked fish and chips come in at 200w. Watch Rob work out why the Champions League takes up less energy than the Europa, and how he’s developing his own, open-source programme, which anyone can use to help them make informed decisions about their carbon lifestyle.

Smith’s story will grace the big screen tomorrow evening at a special screening at the Shortwave Cinema, Bermondsey Square, London. He is among five finalists in a national competition run by Affinity Sutton to encourage residents to share their experiences of how they make a positive contribution to the environment.

The five finalists worked with a specialist social enterprise company to create the films which are being put to the public vote on Twitter and via the Affinity Sutton website. The winner will receive an all expenses paid trip to The Eden Project.

Smith adds: “Over the last few years I have been measuring my energy use and then trying to reduce it. But I found that the calculators online were mostly based on estimates. I wanted to develop one to measure absolutely everything you buy, eat and use. I think a lot of people will find it interesting because it provides a more accurate way of measuring your carbon footprint.”

Other green residents include Jeannie and Eddie, from East Grinstead. After approching their housing officer to see if they could plant some bulbs in some disused space, they launched the Salad Project. Over the last year the residents have planted potatoes, runner beans, French beans, and some herbs. An old dustbin was turned into a water butt by a resident, and there is now a composter for food waste.

Then there’s Phil, from Manchester, who uses a “smart plug” to monitor how much energy appliances are using and Tony, Steph and Brian, from Middlesbrough, who launched a recycling facility on their estate. Christine, Ian and Tom, from Stoke, meanwhile, turned a derelict piece of land into a community garden with wildlife area and community classroom facility.
