Nuclear and renewable energies, master cards of UK

UK's greenhouse gas emissions have increased in 2004 and 2005 and the country is no longer self-sufficient with respect to energy supplies. In front of global warming and energy security threats, UK is reconsidering its energy policy. Based on low carbon solutions, the UK energy economy tries to valorize renewable energies: recovery of methane, combined combustion of biomass and fossil fuels, development of offshore wind and wave power, etc. One reason is also for UK to locally recover part of its lost autonomy thanks to energy decentralization. Since 2006, public hearings have been launched to consider a renewal of the present nuclear park, a development of offshore gas storage and LNG terminal facilities and a promotion of cogeneration systems.
