Europeans are leading the way in using these forms of energy. Prospects are increasing for the deep-sea mining of other minerals, including gold, silver, and the copper, cobalt, nickel, and rare earth minerals (many of which are used in high-tech devices) held within manganese nodules strewn across much of the world's seafloor.
