Unsubsidized Wind is basically cheaper per the second graph on that report.
Unsubsidized Solar is right in the middle of nuclear
Coal is already uncompetitive, it's existence in the market is driven by availability of financing and material to replace it: energy companies are losing money on coal.
The holy grail is unsub wind/solar beating gas combined cycle, but I'll take subsidized. Coal and nat gas are implicitly subsidized: aside from the usual subsidies oil/gas get, they aren't subject to realistic carbon taxes.
I was going to make a comment saying the nuclear was fundamentally noncompetitive today, but that's not true per the graph. Nuclear is surprisingly still competitive, it's just that those plants are ancient and dangerous PWR/LWR almost across the board, Fukushimas waiting to happen.
What is needed is LFTR or other new generation projects, but the issue with those is they are 10-20 years out, even if we had a proven design. Solar/wind have a lot of price dropping still to go as economies of scale kick in. No one knows what the costs will be in 10-20 years, so how do you finance a nuke plant given you don't know a realistic profitable cost?
Also, Yucca mountain was a crappy idea. We should have had LFTRs in use at a minimum to be used to process/breed spent nuclear fuel rods and waste. As I understand it, LFTR can burn/use/convert nuke waste to power or other usable fuel.
Or we should have been on LFTR the whole time with its ability to use 99% of nuclear fuel.
But the boat was missed on this two or three decades ago. We are riding solar/wind and whatever remains for baseload/evening and storage.
What we NEED is a rapid phase-in carbon tax on coal/gas that is directly fed to consumer solar/storage and utility solar/wind.
- Gwypaas 5y agoKeep in mind that the second graph is the marginal cost. The first graph includes the numbers necessary for the initial investment in new builds. Fram that it is easy to see that nuclear new builds are completely uneconomical.
