You're trying to argue that the solar market in 2020 looks the same as it did in the 1970s? Seriously? When the cost of solar PV has dropped 70% just in the last decade alone...?

I can't even find LCOE figures that far back, but the cost of solar modules in 1975 was just over $100 a watt. Today, a solar panel can cost as little as $0.50/W

That's literally a TWO HUNDREDFOLD decrease in price, and modern panels last longer. This is like arguing that computers are useless in 2020 because in the 70s they were not very powerful.

> If batteries actually get cheap then we can do 2x wind+battery, but that isn't here today

Battery storage costs have already dropped 75% over the last 6 years, and we're pretty close to making that possible: https://www.greentechmedia.com/articles/read/report-levelize...

In the field, people bidding on energy projects are doing mixed solar+storage and wind+storage at prices comparable to nuclear or lower. Today. With 2020 tech and 2020 pricing, not 2025, not 2030. Granted, these aren't including a lot of storage right now (1-4 hours generally) but as battery prices continue to drop that will increase.

Given how costs are dropping as the technologies scale up, in 2025 people won't even think twice before choosing renewables+storage over nuclear, because it'll be a no-brainer.

> What we have today are nuke plants, just like we did 40 years ago.

Yes, that's the problem. Nuke plants plants have advanced technologically in the last 40 years, but in terms of cost they're actually more expensive because we found more failure modes (and need to prevent them).

And this is disappointing because I worked in nuclear physics for a few years and really wanted to believe that nuclear energy was going to save us... and it catastrophically failed to deliver.
