Ahead of the sun, sea and breeze game

Outside the white-walled town of Moura in the rolling plans of southern Portugal, more than 240,000 solar panels covering an area equivalent to 150 football pitches are slowly being manoeuvred into position in what will be the world's biggest photovoltaic power plant. A few kilometres away, at Alqueva, the Guadiana river has been dammed to create the largest reservoir in western Europe and one of 18 hydroelectric power projects under way in Portugal's river valleys. In the north-west Alto Minho region, one of the world's biggest wind farms is under construction.
