Report: World trending to hit 50% renewables, 11% coal by 2050

Bloomberg New Energy Finance released a new report this week that estimates how electricity generation will change out to 2050. The clean energy analysis firm estimates that in a mere 33 years, the world will generate almost 50 percent of its electricity from renewable energy, and coal will make up just 11 percent of the total electricity mix.

Add in hydroelectric power and nuclear energy, and greenhouse-gas-free electricity sources climb to 71 percent of the world's total electricity generation. The report doesn't offer a terribly bright future for nuclear, however, and after a period of contraction, the nuclear industry's contribution to electricity generation is expected to level off.

Instead, falling photovoltaic (PV), wind, and battery costs will cause the dramatic shift in investment, Bloomberg New Energy Finance (BNEF) notes. "PV and wind are already cheaper than building new large-scale coal or gas plants," the 2018 report says. In addition, BNEF expects that more than $500 billion will be invested in batteries by 2050, with two-thirds of that investment going to installations on the grid and one-third of that investment happening at a residential level.
