Up to 27% of emissions in the UK come from households, which means changing domestic energy use will have a fundamental part to play in contributing to Government's target for an 80% reduction in greenhouse gases by 2050. It is critical that the UK manages to implement a huge shift in the way it obtains and uses energy. How to deliver the 'Big Energy Shift' was the focus of a series of deliberative discussions with 270 householders from nine communities in England, Wales and Northern Ireland, facilitated by Ipsos MORI. The project was commissioned and supported by the Department of Energy and Climate Change, the Northern Ireland Executive and the Welsh Assembly Government. The objective was to establish the bases on which the public would be prepared to take up renewable energy generation and energy conservation.
