Scotland’s weather and its unique landscape makes it the best place in Britain for hydro power. The Tummel Valley Scheme collects water from 1,800 square km of the Grampian Mountains. Engineers designed the scheme so that water cascades downhill through a series of reservoirs and power stations. The same water generates power up to five times on its journey from the Highlands to the sea. Hydropower represents one form of green energy that supplies homes in Scotland and it’s no surprise that our other main natural resource is wind. Wind turbines provide most of the renewable energy produced here.
