Renewable Energy in Scotland

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. The natural resource base for renewable energy is extraordinary by European, and even global standards, with the most important potential sources being wind, wave, and tide.

At the end of 2011, there was 4,796 megawatts (MW) of installed renewables electricity capacity in Scotland, an increase of 9.5 per cent (416 MW) on the end of 2010. Renewable electricity generation in 2011 was a record high at 13,750 GWh - an increase of 44.5 per cent on 2010. Around 35 per cent of Scotland’s electricity came from renewables in 2011, exceeding the Scottish Government’s target of 31 per cent. Scotland contributed almost 40 per cent of the UK’s renewables output in 2011.

Continuing improvements in engineering and economics 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 market incentives, it is probable that there has been a significant, and in all likelihood long-term change, in the underpinning economics.

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. 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.
