Terrawatch: scientists turn to drones to find raw materials

In Germany, scientists are using drones equipped with sensors to locate metals needed for wind turbines and solar panelsWe know that renewable energy can help the world to wean itself off fossil fuels, but keeping up with green-energy demand is creating another problem. Countries such as Germany, which has committed itself to a low-carbon future, are finding themselves short of the raw materials required to manufacture wind turbines and solar panels. In particular, metals such as copper, cobalt, platinum-group metals and rare-earth elements such as indium and germanium are in short supply.Continue reading...
