Article: Portugal has considerable resources of wind and river power, the two most cost-effective renewable sources. Since the turn of the 21st century, there has been a trend towards the development of a renewable resource industry and reduction of both consumption and use of fossil fuel resources. In 2006, the world's largest solar power plant at that date, the Moura Photovoltaic Power Station, began operating near Moura, in the south, while the world's first commercial wave power farm, the Aguçadoura Wave Farm, opened in the Norte region (2008).
