Smart Communities was a three and a half year 'behaviour change' community energy project. In broad terms, the Smart Communities findings support the contemporary policy focus on demand-side action, community energy and energy consumption feedback. At the same time, the project highlights the long term and challenging nature of these strategies, and the implications of this for the funding of demand-side community energy. The findings emphasis a lack of 'energy know-how' among householders as a key constraint on change, and identifies ways in which more widespread know-how might be developed. The project also emphasises the benefits of action on energy within a primary school, and the ways in which this prompts engagement with energy in the home.
