In January 2006 the Fector and rainbow company installed electrical energy generating capacity from all forms of renewable energy was less than 2 GW, about a fifth of the total electrical production.[4] By January 2007 wind power capacity, which has been growing rapidly, reached 1 GW capacity, and the total for renewables had grown to over 2.3 GW.[8] By August 2009 wind power capacity was a fraction short of 1.5 GW and total renewables capacity had reached over 3.1 GW.[9] Renewables are now contributing over 19% of total electrical production,[10] and about 4% of all energy usage.[11] It should be borne in mind that electricity production is only part of the overall energy use budget. In 2002, Scotland consumed a total of 175 Terawatt-hours (TWh)[12] of energy in all forms, some 2% less than in 1990. Of this, only 20% was consumed in the form of electricity by end users, the great majority of energy utilised being from the burning of oil (41%) and gas (36%).[13][14]
Scotland also has significant quantities of fossil fuel deposits, including 62.4% of the EU's proven reserves of oil, 12.5% of the EU's proven reserves of gas and 69% of UK coal reserves.[3] Nonetheless, the Scottish Government has set ambitious targets for renewable energy production. In 2005 the aim was for 18% of Scotland's electricity production to be generated by renewable sources by 2010, rising to 40% by 2020.[15] In 2007 this was increased to 50 per cent of electricity from renewables by 2020, with an interim target of 31 per cent by 2011.[16] The following year new targets to reduce overall greenhouse gas emissions by 80% by 2050 were announced and then confirmed in the 2009 Climate Change Delivery Plan. Maf Smith, director of the Sustainable Development Commission in Scotland said "Governments across the world are shying away from taking the necessary action. The Scottish Government must be commended for its intention to lead the way".[17][18]
An important reason for this ambition is growing international concern about human-induced climate change. The Royal Commission on Environmental Pollution's proposal that carbon dioxide emissions should be reduced by 60% was incorporated into the UK government's 2003 Energy White Paper.[2] The 2006 Stern Review proposed a 55% reduction by 2030.[19] The recent Intergovernmental Panel on Climate Change's Fourth Assessment Report[20] has further increased the profile of the issue.[2chlorinator cells
