Up to 139 countries could use 100% renewables, researchers claim

Scientists at Stanford University in the US found that for 139 countries, 100% renewable energy use for all purposes is possible by mid-century. Wind would take up a sizeable proportion of this, with 23.5% of the total being provided by onshore wind and 13.6% by offshore — a total of 37.1%. To reach this target, an equivalent of more than 2.5 million 5MW turbines would need to be installed by 2050, the team calculated. This would add a total of 12.5TW of capacity. Under this model, only solar PV would provide more energy (57.6%), the researchers believe. The roadmaps for the 139 countries — 71% of the world’s 195 nations — are "far more aggressive than what the Paris agreement calls for", the scientists admit. But the plans are "still technically and economically feasible", the team of researchers, led by a professor of civil and environmental engineering, Mark Jacobson, w...
