As climate change has led to an alarming 1.6 °F (0.9°C) increase in the globe's average surface temperature since 1906, there is an urgent need for clean and green ways to produce power. Glaciers and ice caps are melting and sea levels are rising, and in response countries from China to Norway to the UAE have been planning huge and innovative projects and programmes to generate electricity in a more sustainable and environmentally-friendly way. From solar parks as big as Caribbean islands to fleets of electric buses, drones and cars, these are some of the ventures galvanising the planet.
