Menhaden: the fish at the bottom of the ocean food web

Preface. Oil has allowed us to extract 90% of the fish in the ocean by being able to go to the ends of the earth using sonar and spotting planes to find the last schools.

Menhaden have been overfished for decades because this profitable industry has been powerful enough to prevent reform for over 20 years.

Even more money could be made, by more people, if there were a 10 year moratorium on catching them, because they are the main fish at the bottom of the food chain that eat biomass (phytoplankton) on the East Coast of the U.S. If their numbers could be brought back to what they once were, the population of blue fin tuna, striped bass, redfish, bluefish, and humpback whales, just a few of the 79 species that feed on menhaden, would explode and create many commercial and sports fishing jobs.

68 Reasons why wind turbines cannot replace fossil fuels

Source: Leonard, T. 2012. Broken down and rusting, is this the future of Britain’s ‘wind rush’?

Preface   Last updated 2025-5-13

  1. The most important problem to be solved is electrifying transportation, otherwise how can you deliver the 30,000 parts of a Vestas 6MW wind turbine to the assembly factory and deliver it to the final site on gigantic trucks assembled with a gigantic crane? Or mine iron ore for the turbine, turn it into steel at 3000 F (70% made this way, not electric arc furnaces), deliver cement for the 2000 ton turbine platform?  
  2. If you do that, then each wind turbine must generate enough electricity to build another turbine (and decommission and recycle the old one) PLUS deliver huge amounts of electricity to society for home appliances, computers, the financial system, and all the other 14 major sectors of the economy that run on electricity.  
  3. There are no COMMERCIAL electric ways to make cement, iron, steel, other metals, glass, ceramics, bricks and so on. Steel recycled by an electric arc furnace is down-cycled and no longer suited for many purposes that require steel with certain alloys for strength and other qualities. Methods are still experimental, if they work, and are cheaper than fossils, and it would take decades and hundreds of billions of dollars to modify/build new manufacturing facilities. If they are more expensive, manufacturers will do nothing, and if forced to by regulations, move their facilities to where fossils are allowed. 
  4. The grid needs to grow 3-fold and thousands of square miles of solar and wind farms to generate the electricity (most net zero plans call for 70-90% of electricity from wind & solar). 
  5. Lubricants, epoxy, plastics and other essential components of wind turbines are made out of petroleum.  So a way must be found to make them (and 500,000 other products)
  6. If you can do all of the above, the wind turbine must be able to construct energy storage devices to store excess electricity for times when the wind isn’t blowing.  There are only four choices. Three have limited places to put them — pumped hydro storage, compressed air, and concentrated solar plants with thermal storage. The only battery for which there are enough materials on earth to store just one day of U.S. electricity generation are Sodium-Sulfur (NaS) batteries. They would weigh 450 million tons, take up 923 square miles, and need to be replaced every 15 years.  And you’d need at least 28 of them to cope with seasonal wind shortages of four weeks or more. 
  7. If you can electrify transportation and manufacturing, make essential components out of something besides fossil fuels, and build 26,000 square miles of NaS batteries, then you’d need to build at least three or more times the number of wind turbines required to store excess electricity. And replace them every 20 years.
  8. If you can do all of the above, then data centers, AI, and bitcoin will consume the electrons before anyone else gets them.

Colonization of Mars & The Moon: a book review of “A City On Mars”

Preface. There are so many difficulties to overcome to colonize Mars. If the astronauts can even survive the bombardment of radiation on the way there.

Where would the energy come from? There is no flowing water for hydropower. Wind and solar have many issues, let alone the cost of flying them there or building them on mars with new factories powered by? There are some hopium proposals for Martian wind power, but to make use of the ultra thin atmosphere the turbines would have to be huge. Geothermal energy, where heat is drawn from deep underground, won’t work on the geologically quiet Moon. It might work on Mars, but would be another enormous on-site construction project, and the best locations for geothermal power may not be the best locations for an early Mars habitat. Solar won’t work because space dust will clog the panels. Nuclear power may explode in a giant Ka-Boom!

Fill ‘er up with kelp?

Preface. Here are just a few of the dozens of reasons why seaweed can’t make a dent in energy supplies:

  • A negative return on investment like corn ethanol
  • No commercial biofuels are being made from it. Kelp is mainly used for food, animal feed, fertilizer, cosmetics, etc.
  • As a monocrop it is just as vulnerable to pests as land crops and pesticides can’t be used to protect them
  • The most desirable kelp is the massive brown variety which only grows in water 43 to 57 F where there are rocks to attach to and protected from storm waves and strong currents
  • Like land biomass, it doesn’t scale up (Friedemann 2007). A U.S. Department of Energy study states that if we could increase world-wide production of seaweed 10.5 fold, we could produce 1% of United States domestic gasoline supply (Roesijadi)

And if Jehn et al (2024) is right, we’ll need all the seaweed we can get to survive after a nuclear war. This is because nuclear winter will block sunlight and prevent crops from growing.  But some plants may survive better than others, especially seaweed, which is also very nutritious. After all, do you want to eat, or drive?

European Power plants are burning American forests

Preface. More than half of Europe’s “green” energy comes from burning wood, a lot of it imported from America.  Now Denmark would like to import methanol made from pinyon pines and junipers from hundreds of thousands of acres in the Southwest. And American biomass burning electric plants would like to burn them as well. The first article below is about the consequences of doing that.

The second article, from Science, doesn’t address the fact that after you cut down a forest and convert the wood into pellets destined to be burned in European furnaces for “clean energy”, the next forest won’t grow back with nearly as much lumber. So CO2 isn’t being replaced, not even after 100 years. Forests don’t regrow to their former magnificence because logging causes soil erosion, depletes the water retained in soil needed for regrowth, and compacts the soil (Elliot 1999).  Therefore the new growth won’t be able to absorb as much CO2 as their burned parents emitted because they contain less biomass, and since it takes half a century for a forest to regrow, whatever CO2 replacement occurs will take an awfully long time. Too long given the State of the World.

Peak Potassium threatens crops

Potassium is one of the Big 3 essential plant nutrients that has allowed human population to soar to 8 billion people,as well as phosphorus and nitrogen. Potassium is a vital nutrient for plant growth that helps with photosynthesis and respiration, the lack of which can inhibit plant growth and reduce crop yields. Farmers often spread potassium-rich fertilizers over their fields to replenish the depleted nutrient.

Rawashdeh (2020) found that potash (the mineral potassium comes from) was likely to peak in 2057 using the Hubbert logistic model, or 2060 using the Gompertz model. Depending on reserve assumptions, the maximum production peak could be anywhere from 2029 to 2095. Regardless of the model, energy shortages, wars, supply chain failures, economic, and political factors can also lead to shortages.

Permafrost & lack of gravel will limit arctic natural gas, oil, and coal extraction

Preface. For many people, it’s comforting to know that about 25% of remaining oil and gas reserves (we have the know-how and economics to get it) and resources (beyond our technical and/or monetary capability) are in the arctic. They assume we’ll get this oil and gas when we need to, and delay oil shortages for a decade or more.

America is not the good guy anymore

Preface.  This is a book review of Toft & Kushi’s 2023 Dying by the Sword: The Militarization of US Policy.  Oxford University Press.

They make the case that America is not the good guy anymore, and hasn’t been for a long time, having undertaken nearly 400 military interventions since 1776, half since WWII. The book is full of lists of battles and more that really bring home the extent of U.S. interventions and wars. Now we are a nation to be feared, like Russia or China, especially with our turn towards authoritarian leaders and new $1.5 trillion dollar nuclear weapon upgrade program.  Rather than use diplomacy, we wage wars, and this has bloated the military budget beyond all reason and diverted resources away from health care, education, infrastructure, job creation, social welfare and more.

Shrink the military budget

Preface. Much of this post is based on Miriam Pemberton’s 2023 book “Six Stops on the National Security Tour”.  Large sections of the book are about why past attempts to cash in on the ending of the cold War since 1991 or even before that didn’t work out. She proposes that military funding should be diverted now to prevent the climate crisis to set up companies to build electric vehicles, wind turbines and more.

Of course, that won’t work! That is what my books and this website go to great lengths to explain.  Renewables are not renewable. They depend on fossil fuels every single step of their life cycle.

But I like the idea of using the military money to do whatever we can now to make life better for future generations.  For starters, let’s stop our endless military engagements as much as possible and use more diplomacy. Continue reading

World Scientists’ Warning: Ecological Overshoot & Human nature

Preface.  It is rare for a mainstream newspaper to bring up overshoot, so congratulations to the scientific paper of Merz et al (2023) for appearing in The Guardian.  It is so frustrating for those of us who are ecologically aware to see only climate change mentioned and not biodiversity, ocean acidification, and a dozen more factors driving the 6th extinction, with the only “solution” on offer to consume more, but Greenly, with renewable energy that will cause up to 37% of Earth’s surface to be mined for the metals to make just the first generation of them for 20-30 years.
