Global energy resources. Conceptual image of a fuel gauge on the Earth approaching empty (E). This represents global environmental issues relating to energy resources and their depletion. This includes the point when large reserves of new oil are no longer found and oil production starts to decline from its peak. Once oil reserves decline, either alternative fuel and power technologies will need to make up the shortfall, or energy consumption will need to be cut.
