a feasible way to avoid the risk of energy decline and combat climate change is to build a 100% renewable global energy mix. however, a globally electrified economy cannot grow much above 12 electric terawatts without putting pressure on the limits of finite mineral reserves. here we analyze whether 12 tw of electricity and 1 tw of biomass (final) power will be able to fuel a future post
the secondary phosphate deposits may last another 30 years. the rehabilitation of mined land and the replacement of income from phosphates are serious long-term problems. in anticipation of the exhaustion of nauru's phosphate deposits, substantial amounts of phosphate income were invested in trust funds to help cushion the transition and provide for nauru's economic future.
