The document summarizes a research project examining public attitudes towards transforming the UK's whole energy system by 2050. The project uses multiple methods including public deliberations, an online scenario tool called My2050, and a national survey. Key findings include that the British public widely supports changing how energy is produced and used, and favors including high levels of renewable energy like offshore wind. National governments are seen as playing a large role in bringing about energy system changes. Successful public engagement was achieved through using mixed methods and addressing the public's long-term vision and values.
