On a barren, sun-baked plateau in southern Spain, row upon row of gleaming mirrors form one of the world's biggest solar power plants and harness the sun's power even after dark. The Andasol plant provides electricity for up to about 500,000 people from about 620,000 curved mirrors. The glass alone would cover 1.5 square km (0.6 square miles) - the size of about 210 soccer pitches.
