The continuing case for nuclear energy

Climate mitigation scenarios envision considerable growth of wind and solar power, but scholars disagree on how this growth compares with historical trends. Here we fit growth models to wind and solar trajectories to identify countries in which growth has already stabilized after the initial acceleration. National growth has followed S-curves to reach maximum annual rates of 0.8% (interquartile range of 0.6–1.1%) of the total electricity supply for onshore wind and 0.6% (0.4–0.9%) for solar. In comparison, one-half of 1.5 °C-compatible scenarios envision global growth of wind power above 1.3% and of solar power above 1.4%, while one-quarter of these scenarios envision global growth of solar above 3.3% per year. Replicating or exceeding the fastest national growth globally may be challenging because, so far, countries that introduced wind and solar power later have not achieved higher maximum growth rates, despite their generally speedier progression through the technology adoption cycle.

That is a new paper from Nature Energy, by Aleh Cherp,, via the excellent Kevin Lewis.  Yes, yes, Moore’s Law for solar cost and all that, but we need to think about the problem more deeply and that still implies a significant role for nuclear energy.  And here is some good news:

Finland has joined France, Poland, Hungary, the Czech Republic in lobbying the European Union to categorize nuclear power as sustainable. According to the Finnish Broadcasting Company, Finland’s pro-nuclear lobbying marks a U-turn within the Green Party.
