The keyChallenges related to renewable energies, such as to extract it, turn it into usable energy and to deliver where it is needed. Not known for being the sunniest places, the UK has some of the best wind-power resources in Europe and is a world leader in marine technology. Although the wave and tidal power technologies are still in their infancy, the Carbon Trust estimates that providing maritime energy sources up to 15% of the UK's electricity could. In May 2008 the world's firstcommercial tidal turbine installed in Strangford Narrows, Northern Ireland, the supply of electricity to 1,000 homes.

Growing at a global rate of 30% is wind power the most sophisticated and cost-effective renewable energy technology: the world in 2008 there were 121 GW wind power installed, with the United Kingdom accounts for about 4 GW of installed capacity by the end of the 2009th Under the EU directive on renewable energies, the UK government has signed a legally binding target ofGenerating 15% of UK energy from renewables by 2020. This is a seven-fold increase from 2008 to just over 2%. Renewable electricity generation in Britain is at a very low level compared to other countries such as Denmark, Spain, Germany and the USA. There is a mountain to climb if the 15% target for energy efficiency.

The UK 's Renewable Energy Strategy published in 2009, in July 2009, outlines how to achieve the Government to meet its ambitious target, renewable energy plans.Specific objectives include the production of more than 30% of electricity from renewable sources (compared to around 5.5% today), especially on-and off-shore wind energy, as well as hydropower, biomass and marine power technologies. Transport energy from renewable energy sources must be from the current 2.6% to 10% and 12% of the heat energy is expected to come from sources such as biomass, solar and biogas.

Together with carbon capture and storage, carbon emissions trading, new nuclearSkills, and saving and measures to increase renewable energy part of the plan the government will move the UK towards a low carbon, more energy self-sufficient that they are treated both climate change and energy security issues.

If the strategy is achieving its objectives, the UK's carbon dioxide emissions by more than 750 million tons of reduction until 2030. Consumption of fossil fuels by about 10% and gas imports decreased by 20 to 30% by 2020.The strategy predicts that could achieve the objectives of half a million jobs in renewable energy by 2020 to create and use £ 100 billion euros of investment opportunities.
