The Centre for Sustainable Energy (CSE) is an independent national charity, established in 1979 to advance sustainable energy policy and practice. We share our knowledge and practical experience to enable people and organisations to change the way they think and act about energy. We do this by giving advice, managing innovative energy projects, training others to act, and undertaking research and policy analysis. At any one time we have between 50 and 60 different and separately funded projects under way. We are based in Bristol although much of our work has relevance and impact across the UK. Our clients and funders include national, regional and local government and associated agencies, energy companies and charitable sources.
