The production of renewable energy in Scotland is an issue that has come to the fore in technical, economic, and political terms during the opening years of the 21st century.[1] The natural resource base for renewables is extraordinary by European, and even global standards. In addition to an existing installed capacity[a] of 1.3 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.[2][3] 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.[2][4]
Much of this potential remains untapped, but continuing improvements in engineering are enabling more of the renewable resources to be utilised. Fears regarding "peak oil" and climate change have driven the subject high up the political agenda and are also encouraging the use of various biofuels. Although the finances of many projects remain either speculative or dependent on subsidies, it is probable that there has been a significant, and in all likelihood long-term change, in the underpinning economics.[5]
In addition to planned increases in both large-scale generating capacity and microsystems using renewable sources, various related schemes to reduce carbon emissions are being researched.[6] Although there is significant support from the public, private and community-led sectors, concerns about the effect of the technologies on the natural environment have been expressed. There is also an emerging political debate about the relationship between the siting, and the ownership and control of these widely distributed resources.chlorinator cells
