A group of "concerned citizens" in Tarifa, currently home to the biggest cluster of wind turbines in Europe, have set up an organisation which aims to reduce the impact of wind power on the local community. Called the Confederation for the Limitation of Air Turbines (COPLA), the group plans to lobby local officials, wind turbine manufacturers and developers, and regional and national authorities to ensure sustained growth of the industry in the area with minimum impact on the environment, including noise and sight pollution. COPLA's Cristina Parkes says the organisation would share and expect to receive information regarding wind power in Tarifa with the aim of encouraging the public's full participation in the ongoing debate surrounding this form of energy. COPLA, one of the first non government organisations in Europe expressly targeting wind power, is mainly concerned about the influence wind turbines have on birds and the scenery. Tarifa is a main thoroughfare for migratory species. The local authorities have agreed to evaluate COPLA's considerations before further expansion of Tarifa's current 72 MW is considered.
