The UK government has introduced regulations that require electricity distributors to source a portion of their electricity supply from renewables (including hydroelectricity), currently 3 percent but set to rise to 10 percent by 2010. Investments in wind power have increased substantially, aiming to take advantage of the natural geographic advantage that the UK has in this regard. Another area of increased interest has been wave power. In 2004, the Pelamis project off the coast of Orkney delivered the first ever supply of electricity from wave energy to the UK national grid. Finally, hydroelectricity has regained attention, especially in Scotland, including the potential construction of the 100-MW Glendoe project.
