Why is this graph comparing to nuclear and not fossil fuel? This is counter-productive as long as fossil fuel power plants exist.
2010: wind+solar just aren't powerful enough technologies to scale to the problem. 2012: wind+solar are fine, but too dependent on subsidies. 2016: wind+solar are now too cheap, and it's messing up powergrid economics. 2019: let's rip out the old, and replace w/ wind+solar.pic.twitter.com/CzRAEabzcB

It looks like wind and solar could overtake nuclear by 2020 or at least by 2021. WS will likely overtake coal and gas before nuclear does.

Imagine the combined growth if we were also investing in nuclear

Power generation from coal in the US will likely fall just below 1000 TWh this year, and combined wind+solar will likely get close to 400 TWh. So here's a chart that many asked for: the comp we really care about. (through 2018)pic.twitter.com/vUBRMY6xUi

No one seems to talk about the negative climate impact from renewables due to the enormous land footprint that is needed. Can’t imagine how India and China will find large tracts of contiguous land near population centers to keep adding wind & solar.

My view would be the "land availability argument" is about ten years old now, and it originally arose as a kind of intuition or hunch about the power density problem of wind and solar. There is no argument: W+S are very low power density. But land problem argument has faded.

A more interesting graph could be to plot the annual increase of electricity demand and annually added solar+wind. BP data suggest that the load increases on average with just above 600 TWh. The global factory capacity to manufacture 600+ TWh solar+wind will be reached 2021-ish.

Yes, that is one of the most important ratios and one that I track also. For example, in 2015-2017, new generation from renewables was doing quite well against total global elec growth. But last year, 2018, total growth bolted to the upside. See:https://twitter.com/GregorMacdonald/status/1142086621103136768 …
