Paper (441 times, compared to 55 to be exact), the government does not propose building new stations itself. Instead, it will leave it to the market, although it will ease some of the planning constraints (which it also aims to do for renewables) and look into providing a design authorisation procedure. As with many other aspects of the Energy Review Response, the document is not likely to be the last word on the subject, as there are plans for further consultation, and the establishment of further reviews and studies in issues such as identifying suitable sites, and managing the costs of decommissioning and long term waste management. Energy white paper, 2007 The 2007 energy white paper: Meeting the Energy Challenge was published on 23 May 2007. The 2007 white paper outlines the government's international and domestic strategy for responding to two main challenges: cutting carbon emissions to tackle global warming ensuring secure, clean and affordable energy as imports replace declining production from North Sea oil and gas It seeks to do this in a way that is consistent with its four energy policy goals: cutting the UK's carbon dioxide emissions by some 60% by about 2050, with real progress by 2020; maintaining the reliability of energy supplies; promoting competitive markets in the UK and beyond, helping to raise the rate of sustainable economic growth and to improve productivity; and ensuring that every home is adequately and affordably heated. The paper anticipates that it will be necessary to install 30–35 GW of new electricity generation capacity within 20 years to plug the energy gap resulting from increased demand and the expected closure of existing power plants. It also states that, based on existing policies, renewable energy is likely to contribute around 5% of the UK's consumption by 2020, rather than the 20% target mentioned in the 2006 Energy Review. Proposed energy strategy In summary, the government's proposed strategy involves six components: Establishing an international framework to tackle climate change, including the stabilisation of atmospheric greenhouse gas concentrations and a stronger European Union Emissions Trading Scheme Providing legally binding carbon targets for the whole UK economy, reducing emissions through the implementation of the Climate Change Bill. Making further progress in achieving fully competitive and transparent international markets, including further liberalisation of the European Union energy market. Encouraging more energy saving through better information, incentives and regulation Providing more support for low carbon
