The world will experience numerous cases of overshoot and decline before 2052

Jorgen Randers : climatologist
About 87% of today’s global energy use is supplied by coal, oil, and gas; energy intensity will fall by a third by 2052 while the global economy doubles—thus energy use will grow by 50%; Use of conventional oil has probably peaked, and peaks in both coal and gas use are expected before 2040 due to very rapid increase in use of renewable energy, which will grow from 8% of energy use in 2010 to 37% in 2050 (this shift will be slowed by the cheap intermediary solution of replacing coal with gas); the nuclear share of world energy will be one-half of today’s contribution—below 3%;
