There are two main energy challenges: tackling climate change by reducing carbon dioxide emissions; and ensuring clean and affordable energy as the country becomes increasingly dependent on imported fuel. These challenges have to be met against the backdrop of rising fossil fuel prices; slower than anticipated liberalisation of the EU energy markets; heightened awareness of the risk arising from remaining oil and gas reserves being concentrated in a few geographical regions; and a need for substantial new investment in power stations, the electricity grid and gas infrastructure. This White Paper sets out the Governments international and domestic strategy to address these challenges and ways to implement the Energy Review of 2006 and the 2006 Pre-Budget Report. There is a separate consultation document on nuclear power.
