Passionate about climate change and inspired by her experience living with nomads in southwestern Iran and Iraq, Sue Roaf wanted to find a way to live her life while using as little energy as possible. With the help of her friends, that pursuit ultimately led her to build the first solar roof in Britain. Today, her six-bedroom house in north Oxford uses minimal energy in both summer and winter, with an average electricity bill of just £40 per month and the surplus sent back into the grid.

100Green is the UK’s only supplier of 100% fossil fuel-free electricity and gas. They commissioned us to make a series of short documentary pieces profiling some of the inspiring and forward-thinking people that make up their supplier network across the UK.

In this short film, Sue tells the story behind the now-famous Oxford Ecohouse, almost thirty years since the project began, and of ‘doing well by doing good’.
