Copper is used in making electronic devices. Describe how the use of copper might change as copper becomes more scarce.

       In the coming decades, copper scarcity is likely to result in deteriorating ore quality, which in turn will lead to a higher GER for copper production. In this study, this increasing GER and the effect it has on the EROI of wind turbine technologies have been analysed. Because of an increasing in-use stock of copper, recycling will play a relatively small role even when the recycling rate is high. The future EROI of wind turbines is approximately 15% less than is currently often taken into account, mainly due to network losses.
