The renewable energy industry supports more than 11,500 jobs in Scotland, according to a 2013 study by Scottish Renewables. With 13.9 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. Although the finances of some projects remain speculative or dependent on market incentives there has been a significant and in all likelihood long-term change, in the underpinning economics.
