The document discusses the UK's experience with clean energy including renewables like biofuels, nuclear power, and carbon capture and storage. It notes that in 2006 renewables generated about 5.5% of electricity while nuclear generated 19%. Strengths included early commitment to renewables and political support, but weaknesses included a lack of coordination between policy, planning, and regulation. Support mechanisms for renewables also lacked effectiveness and led to an uncoordinated growth of small wind farms causing public dissatisfaction.
