In 2023, the CO2 growth rate was 3.37 ± 0.11 ppm at Mauna Loa, 86% above the previous year, and hitting a record high since observations began in 1958[1], while global fossil fuel CO2 emissions only increased by 0.6 ± 0.5%[2,3]....
Numerous prominent petroleum geologists have been warning for years about the resources limitations of oil both in the U.S. and globally.  It’s now looking like the wolf is nearing the door.

This essay takes up and extends an analysis of the ambitions of the energy transition presented during the conference entitled “L’erreur fondamentale de la transition”, held in Lausanne in December 2022, at the annual Switzerland ShiftersDay. The intervention questioned the conceptualization of energy transition, given possible inaccuracies, or errors in the categorization of reality. It is not certain that the energy contained in the wind, solar radiation, or atoms is equivalent to hydrocarbon energy for human societalneeds. Although all energies are theoretically convertible into one another, the assumption that any type of energy can always be replaced by another is likely to prove false. An energy transition based on the substitution of energies would then be inconceivable.

Oil in the North Sea is expected to be net-energy negative by 2031. This means that in 2031, it’ll cost more energy to extract the fossil fuels than we would gain by using them, rendering extraction unfeasibly expensive. Yet, rather than use our remaining years of access to these fuels to turbo-charge new energy infrastructure, fossil fuels are being extracted and burned for business as usual: quick cash. Around the world, the lights will go off in nations that don’t have back-up renewables. That’s most of them.

World’s fossil-fuel producers on track to nearly quadruple output from newly approved projects by decade’s end, report finds
Global investment in the clean energy transition grew by 17% in 2023, showing resilience despite geopolitical tensions, high interest rates, and inflation. But was it enough to keep the world on track to hit net zero by 2050? To answer this question, we compare 2023 clean energy investment by sector with what’s annually needed to reach net zero by 2050, in partnership with the National Public Utilities Council.
In a previous post, I defined this graph as “the most amazing graph of the 21st century.” It shows how the US oil production restarted growing in 2010, picking up speed and surpassing the historical record of the “Hubbert Peak,” which took place in 1970. It overcame the dip caused by the Covid pandemic and, two years after my first post on this subject, it keeps growing.

Small modular reactors (SMRs) have been the subject of endless hype in recent years but in fact, no SMRs have ever been built, none are being built now and in all likelihood none will ever be built because of the prohibitive costs. SMRs are defined as reactors with a capacity of 300 megawatts (MW) or less with serial factory production of reactor components (or ‘modules’). No SMRs have been built, but dozens of small (<300 MW) power reactors have been built in numerous countries, without factory production of reactor components.

New path to transition away from fossil fuels marred by lack of finance and loopholes COP28 in Dubai sends an important signal on the end of fossil fuels but leaves more questions than answers on how to ensure a fair and funded transition that is based on science and equity

Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM2.5” as fine particulate matter associated with coal EGU sulfur dioxide emissions and estimated annual exposure to coal PM2.5 from 480 EGUs in the US. We estimated the number of deaths attributable to coal PM2.5 from 1999 to 2020 using individual-level Medicare death records representing 650 million person-years. Exposure to coal PM2.5 was associated with 2.1 times greater mortality risk than exposure to PM2.5 from all sources. A total of 460,000 deaths were attributable to coal PM2.5, representing 25% of all PM2.5-related Medicare deaths before 2009 and 7% after 2012. Here, we quantify and visualize the contribution of individual EGUs to mortality.
Dear COP 28 President-Designate Sultan Ahmed Al-Jaber, This year, world leaders gathering in the UAE to take stock of their climate commitments will for the first time engage in official programming focused on health. We, the signatories of this letter, support your leadership in bringing health front and center at COP28.

But the decline in oil, gas and coal will not be steep enough to limit global warming to 1.5C
Forecast downturn still ‘nowhere near steep enough’ to limit temperature rise to 1.5C, says watchdog
Energy return on investment (EROI) is a biophysical and ecological economics concept that is useful to think about how organisms, ecosystems and societies must obtain enough surplus energy returned from energy gathering activities to live, reproduce, and thrive. EROI can help us overcome the false dualism between nature and society. EROI is a useful metric for economics because it is based on immutable physical laws rather than sometimes arbitrary human preferences. It is essential for assessing useful power, energy trade-offs, efficiencies (and inefficiencies), resource depletion trends, resource quality, and surplus potentials of different fuels and technologies that power, or might power, our socio-economic systems. Apparent inconsistencies in the literature can generally be reduced or eliminated by paying careful attention and explicitly stating boundaries and definitions. We argue that proper use of EROI is critical to understand the interconnections among the environment, energy, and socio-economic deve
A novel methodology is developed to dynamically assess the energy and material investments required over time to achieve the transition from fossil fuels to renewable energy sources in the electricity sector. The obtained results indicate that a fast transition achieving a 100% renewable electric system globally by 2060 consistent with the Green Growth narrative could decrease the EROI of the energy system from current ~12:1 to ~3:1 by the mid-century, stabilizing thereafter at ~5:1. These EROI levels are well below the thresholds identified in the literature required to sustain industrial complex societies. Moreover, this transition could drive a substantial re-materialization of the economy, exacerbating risk availability in the future for some minerals. Hence, the results obtained put into question the consistence and viability of the Green Growth narrative.

The Energy Institute is, as of 2023, the home of the Statistical Review of World Energy, published previously for more than 70 years by bp. The Statistical Review analyses data on world energy markets from the prior year. It has been providing timely, comprehensive and objective data to the energy community since 1952.
A new climate case was filed this week. Multnomah County, the Oregon county that includes Portland, filed suit against several oil majors for their role in exacerbating the climate change that led to the county's "heat dome" in June 2021, which killed 69 people. But the case doesn't just place
Major fossil fuel entities and trade associations including Koch Industries, the American Petroleum Institute, and the Western States Petroleum Association, as well as consulting behemoth McKinsey & Company, were slapped with the latest climate liability lawsuit today with the filing of a complaint in the Oregon Circuit Court in Multnomah County, Oregon.
A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough--such as by using a model--wind and solar look to be useful. They don't burn fossil fuels, so it appears that they might be helpful to the environment. Energy modeling misses important points. I believe that profitability signals are much more important.
