World Trending To Hit 50% Renewables, 11% Coal By 2050: Report (arstechnica.com)

Bloomberg New Energy Finance released a new report this week that estimates how electricity generation will change out to 2050. ArsTechnica: 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.

33 Years?!

[aaarrrgggh]

I'm guessing we will hit 50% much sooner than 33 years based on the improving economics. I wonder what state the grid will be in at that point though; will de-centralized energy take over, will we see interconnected microgrids, or will it be largely the same as today.

I think the only real question is if SMR's will provide a nuclear renaissance, or if that is still "20 years out." From what I read it doesn't seem like the SMR economics are any better on a $/kW basis than traditional reactors on a construction cost basis, although legal risk and financing costs should (theoretically) be reduced.

Re:Never taken into account by alarmists

This inevitable increase in use of alternative energy is never taken into account by climate models that assume an ever increasing generation of CO2.

No that's yoyu making shit up to fit your agenda.

Look at the future extrapolation bit:

yes, it is sourced.

but sadly that is not how the world works any longer, no one wants real data,

At least you're honest!
