MIT in 2024: But air conditioning, which made active cooling of our homes and offices possible, was only invented in the early 20th century. “This process is still really magical,” Reinhart says. “There's nothing in nature that you can turn on and suddenly it becomes ice cold on a hot day, right? Because it works against entropy. So it's just really fascinating that we can do this at all.”

by Planning Engineer (Russ Schussler) In Part 1, we showed how wind and solar’s low costs over 80% of the time are overwhelmed by expenses at peak times such that they offer no cost advantages to the generation mix. Residential solar follows a similar pattern: it seems affordable for homeowners, but raises system costs through […]

by Planning Engineer (Russ Schussler) Wind and solar power are often touted as the cheapest sources of electricity in many regions, capable of delivering low-cost energy for the vast majority of the time. At first glance, this might suggest that an energy mix heavily weighted toward renewables would be the most economical choice. However, this […]

by Judith Curry and Harry DeAngelo  We have a new paper published in the Journal of Applied Corporate Finance, entitled “A Critique of the Apocalyptic Climate Narrative.” The paper reflects the JACF’s ongoing interest in publishing articles that analyze important Environmental, Social, and Governance (ESG) issues in ways that are useful for investors, money managers, […]

by Russ Schussler (Planning Engineer) On April  28th Spain, Portugal and parts of France suffered a major grid outage. A  formal evaluation will likely be released at a later date cataloging many of the contributing factors and system deficiencies. Unfortunately, such reports often provide more confusion than clarity, as they tend to prioritize the triggers […]

by Douglas Sheil Last week an article in Science, by Seo and colleagues, provided compelling evidence that the world’s land surface is getting drier. This global drying averaged a loss across all land surfaces of over two centimeters of water in two decades. The trends suggest these losses continue. The authors highlighted the role of […]

by Chris Morris Geothermal power stations are mature technology with proven performance, reliable operation and ideal for baseload generation. The units are synchronous, so they support the grid.  The production from them is considered by most to be renewable. They do not use fossil fuels to provide the heat. It is not “carbon free”, but […]

by Ross McKitrick I have a new paper out in the journal Nature Scientific Reports in which I re-examine some empirical work regarding agricultural yield changes under CO2-induced climate warming. An influential 2017 study had argued that warming would cause large losses in agricultural outputs on a global scale, and this played a large role […]

by Planning Engineer (Russ Schussler) The purpose of this article is to summarize and debunk many of the issues in the narrative surrounding  the proposed green energy transition as applies to the electric grid.  The issues are so numerous that this piece is at once both too long and too short. A full unraveling deserves […]

by Russ Schussler (Planning Engineer) Prequel to “Unravelling the narrative supporting a green energy transition.” There is a powerful but misleading narrative supporting a green energy transition. A follow up piece will look more broadly at the general narrative supporting a transition to net zero.  This prequel will provide some detail on a few  components […]

by John Ridgway How an emergent scientific consensus results from social engineering enabled by prosocial censorship. A recent research paper published in The Proceedings of the National Academy of Sciences argued that both self-censorship and the prosocial censorship of colleagues are commonplace within the sciences — and the problem is only getting worse. Some of […]
