It’s the first time. In the first half of 2021, wind and solar energies generated more than a tenth of the world’s electricity (10.5%) and exceeded nuclear production, according to the German think tank Ember. They supplied only 5% of the world’s electricity in 2015. This is further confirmation that wind and solar power are indeed the growth engines of clean electricity. So much the better, because hydraulics and other renewable energies are losing ground. Like the nuclear share. The few new plants built by the China painfully compensate for the shutdowns of old power plants in OECD countries. And that shouldn’t get better. Because few power plants are under construction in the world. Bad news for the climate. Because renewables cannot absorb the increase in demand for electricity in the world.
