If we hadn't stopped building nuclear in the 80s and had merely kept up the pace, we'd be 50% nuclear (instead of 20%) today. If we had continued the accelerating pace, we'd be 100% nuclear. Today. Not in 2050, today. Compare to solar, which only recently broke the 1% mark.
Nuclear has gone from very cost-competitive (5c/kWh) to not at all cost-competitive (alternatively: "financially risky," often shortened to "risky" in a disingenuous attempt to imply something else) because we gave NIMBYs and self-styled environmentalists a free pass to introduce arbitrary delays into the construction process, and they did, and it was very effective at raising the price / financial risk. That is what people mean when they say that we decided to stop building nuclear.
- NeedMoreTea 7y agoThe typically socialised decommissioning costs, far in excess of estimates, of nuclear usually seem to more than cancel out any cost competitiveness. I was quite pro-nuclear in the 80s and 90s...
- SCHiM 7y agoWell, if you agree with the comment you're replying to you'd logically still have to be pro nuclear now. Because the costs of our fossil fuel energy production seem like they'll be the death of our civilization.
- NeedMoreTea 7y agoI've never advocated sticking with fossil though. Nuclear could have bought us lots of extra time to deal with the rest - if all the coal generation had got replaced by nuclear say in the 90s - but that bird flew ages ago. Personally, for most of the 21st century I've seen wind, solar, tidal and (pumped) hydro as increasingly more suited - far faster to bring onstream, and without quite the same scale of NIMBY delays of nuclear. A network of micro generators seems more suited to the adoption of community heat and power which also seems an essential part of reaching zero emission - as seen today in Ireland's emissions plan.
- jjoonathan 7y ago... until we collectively decided to stop leveraging the upsides of nuclear and it turned into just a money pit, rather than a plausible investment. Yeah, I hear you. FWIW I consider it a lost cause these days too. It didn't have to be that way. Sounds like China is making a go for it, though. Maybe in 20 years they can come build some plants to save us from the duck curve.
- NeedMoreTea 7y agoChina is helped there that they can centrally require it. I doubt they have quite the NIMBY issue we typically get for major projects...
