Wind poWerWind power is one of the most environment-friendly sources of energy for large-scale electricity production. It is a renewable form of energy that produces no pollution. Wind turbines produce electricity by convert-ing the kinetic energy of the wind into electrical power. The best available wind resources in Europe are found in Norway and the UK.
