Wider Image: Andasol Solar Power Station
A view of a solar field at the Andasol solar power station near Guadix, southern Spain July 1, 2015. The 620,000 curved mirrors harness the sun's power even after dark, and the glass alone would cover 1.5 square km (0.6 square miles) - the size of about 210 soccer pitches. REUTERS/Marcelo del Pozo
