I turned a comment I made under The Energy Endgame: We AlreadyHave the Tools to End the Fossil Fuel Age into a post. The article was written by “Tyler Norris [who] served as a Special Advisor to the U.S. Secretary of Energy in the Obama administration. Until May 2017, he was a Director at S&P Global Platts/PIRA, a market intelligence consultancy, where he co-led the firm’s cleantech practice.”
There is no indication that he has any engineering background, which may explain why he does not understand basic concepts like baseload and LCOE verses system costs.
The author’s arguments rest on an untested hypothesis. There is no evidence that the world can be powered with renewables alone. From a peer-reviewed study in Science Direct:
While many modeled scenarios have been published claiming to show that a 100% renewable electricity system is achievable, there is no empirical or historical evidence that demonstrates that such systems are in fact feasible.Of the studies published to date, 24 have forecast regional, national or global energy requirements at sufficient detail to be considered potentially credible. We critically review these studies using four novel feasibility criteria for reliable electricity systems needed to meet electricity demand this century.
Eight of 24 scenarios (33%) provided no form of system simulation. Twelve (50%) relied on unrealistic forecasts of energy demand. While four studies (17%; all regional) articulated transmission requirements, only two scenarios—drawn from the same study—addressed ancillary-service requirements. In addition to feasibility issues, the heavy reliance on exploitation of hydroelectricity and biomass raises concerns regarding environmental sustainability and social justice.
The author continues:
Norris doesn’t seem to understand the definition of baseload, which is the minimum level of demand on an electrical grid over a span of time. Most certainly, that is not going to “go bust.” He’s parroting an old antinuclear argument that never did make any sense but continues to bounce around the internet echo chamber. You can provide baseload in any number of ways; including, but only in theory, the use of wind and solar if you have enough storage and/or an intercontinental HVDC super grid.Baseload goes bust
He is right about keeping existing nuclear power stations open, but there is no need to wait for even more advanced nuclear to deploy more nuclear. Nuclear power station designs being built today are perfectly adequate; safe, and if built by the right company, highly economically competitive. Carbon capture is a canard that is distracting from the conversation.That’s why it’s essential to preserve and extend as many existing nuclear plants as possible and continue making long-term public investments in advanced nuclear and carbon capture technology, even if their scale-up is less than likely -- and even if the United States government doesn’t lead.
