This Overview captures the Gemasolar Thermosolar plant in Seville, Spain. The solar concentrator contains 2,650 heliostat mirrors that focus the sun’s thermal energy to heat molten salt flowing through a 140-metre (460-foot) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. In total, the facility displaces approximately 30,000 tonnes of carbon dioxide emissions every year.
The Arlit uranium mine is located in Arlit, Niger. French nuclear power generation, as well as the French nuclear weapons programme, are both dependent on the uranium that is extracted from this mine in the former French colony – more than 3,400 tonnes per year.

The coal terminal at the Port of Qinhuangdao in China is the largest coal shipping facility in the country. From here, approximately 210 million tonnes of coal are transported to coal-burning power plants throughout southern China every year. In 2015, new data from the Chinese government revealed that the country has been burning up to 17 percent more coal each year than previously disclosed. The sharp upward revision in official figures means that China has released almost a billion more tonnes per year of carbon dioxide than previously estimated.

A turbine interchange connects two highways in Jacksonville, Florida. This structure consists of left-turning ramps sweeping around a centre interchange, thereby creating a spiral pattern of right-hand traffic.
Tailings are the waste and by-products generated by mining operations. The tailings seen here were pumped into the Gribbens Basin, next to the Empire and Tilden iron ore mines in Michigan, USA. Once the materials are pumped into the pond, they’re mixed with water to create a sloppy form of mud known as slurry. For a sense of scale, this Overview shows approximately 2.5 square kilometres (1 square mile) of the basin.
Dendritic drainage systems are seen around the Shadegan Lagoon by Musa Bay in Iran. The word ‘dendritic’ refers to the pools’ resemblance to the branches of a tree, and this pattern develops when streams move across relatively flat and uniform rocks, or over a surface that resists erosion.
