Scotland has enough resources to supply all its electricity needs from renewables -- and still have plenty left for the rest of the UK, a study has confirmed. The study, by consultants Garrad Hassan, was commissioned by the Scottish Executive. It shows that by 2010 nearly 60 GW of renewable capacity could be available to Scotland at under £0.07/kWh. Most of the resource is wind -- both onshore and offshore -- wave and tidal. Environment and Rural Development Minister Ross Finnie also points out that there is enough potential energy from onshore wind power alone to meet Scotland's winter peak demand for power twice over. "In all, the total resource amounts to 75% of the total UK existing generating capacity," he says. A separate study of the Scottish electricity grid reveals enough existing capacity to allow the Executive's targets of 18% of electricity supply from renewables to be met without upgrades.
