In addition to an existing installed capacity of 1.65 Gigawatts (GW) of hydro-electric schemes, Scotland has an estimated potential of 36.5 GW of wind and 7.5 GW of tidal power, 25% of the estimated total capacity for the European Union and up to 14 GW of wave power potential, 10% of EU capacity. The renewable electricity generating capacity may be 60 GW or more, considerably greater than the existing capacity from all Scottish fuel sources of 10.3 GW. Scotland exceeded its renewable energy target, set in 2007, for 31% of total power generation coming from renewables by 2011. Scotland eyes 50% renewable energy by 2030.In January 2006 the total installed electrical generating capacity from all forms of renewable energy was less than 2 GW, about a fifth of the total electrical production. 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. By August 2009 wind power capacity was a fraction short of 1.5 GW and total renewables capacity had reached over 3.1 GW. By mid-2011 these figures were 2.76 GW and 4.6 GW respectively.In 2012, over 40% of Scotland's electricity came from renewable energy, and Scotland contributed almost 40% of the UK's renewables output. At the end of 2012, there was 5,801 megawatts (MW) of installed renewables electricity capacity in Scotland, an increase of 20.95% (1,005 MW) on the end of 2011. Renewable electricity generation in 2012 was a record high at 14,756 GWh – an increase of 7.3% on 2011, the previous record year for renewables output. The bulk of electricity production is derived from gas and oil. 2002 figures used in RSPB Scotland et al. (2006) are gas (34%), oil (28%), coal (18%) and nuclear (17%), with renewables 3% (principally hydro-electric), prior to the substantial growth in wind power output. 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) 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 is from the burning of oil (41%) and gas (36%).The renewable energy industry supports more than 11,500 jobs in Scotland, according to a 2013 study by Scottish Renewables. However a 2011 study by 4-Consulting calculated that there was probably a small net loss in jobs in Scotland from government support for renewable energy. They estimated that the offshore wind industry might create between 300–2,200 long-term jobs by 2020. With 20 GW of renewable energy projects in the pipeline, the sector has the potential to grow quickly in the years ahead creating more jobs in the region. Glasgow, Fife and Edinburgh are key centres of offshore wind power development, and the emerging wave power and tidal power industries are centred around the Highlands and Islands. Rural job creation is being supported by bioenergy systems in areas such as Lochaber, Moray and Dumfries and Galloway.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. 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. In 2007 this was increased to 50% of electricity from renewables by 2020, with an interim target of 31% by 2011. 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".An imp
