It offers advice on which renewable technologies are suitable to London including aesthetic issues, risks and reliability. It gives an insight into the cost- benefit analysis of installing renewables, information on successful case studies and suggestions on how problems can be overcome. More importantly it helps to understand how to comply with the requirements of the London Plan and relevant borough development documents. It offers in-depth calculations for use by consultants to help determine the most appropriate renewable for each scheme. One of the main drivers for such policies is global climate change, the impacts of which are just starting to be felt. For London, climate change means hotter, more humid summers; wetter winters and a significant increase in high rainfall in short periods. This was confirmed by the report entitled ‘London’s Warming’, which was commissioned by the London Climate Change Partnership published In October 2002, and launched by the Mayor and Michael Meacher, the Environment Minister at that time. The report was clear that London faces serious financial risks due to climate change. The recent storms in London, along with the wettest August on record are indicative of the changes we are seeing in our current weather patterns. In 1992, the UK signed the Kyoto protocol committing it and other nations to cuts in the emissions of various greenhouse gases, the most significant being carbon dioxide. The Energy White Paper, published in 2003, sets out the UK target of producing 10% of UK electricity from renewable energy by 2010 and the aspiration of doubling this by 2020. This is within the context of the UK carbon dioxide target and the goal of putting the UK on a path to cut carbon dioxide emissions by some 60% by 2050. Recently the Government also published planning policy statement 22 on renewable energy. London is a special case - we use in a year as much energy as Portugal and more than Ireland. London needs to take itself in hand and that is where the Mayor’s energy work comes in. Taking the lead from the national targets, London has set its own target in the London Plan, which should lead to a reduction in London’s carbon dioxide emissions by 23 per cent (based on 1990 figures) by 2016.
