Last year I published a report with the (justifiably) bombastic title, “$500 per barrel: could oil price rise tenfold?” One of my central claims was that producing oil requires investment of real capital including materials, equipment and highly skilled labor, and that, “as more and more resources are required to generate the same amount of liquid fuels, energy production is becoming ever more expensive to society in real terms.” Thus, as it becomes more expensive in real terms (as the deteriorating EROEI figures indicate), the fact that energy has recently become cheaper in nominal (dollar) terms can only be a temporary abberation. EROEI stands for energy return on energy invested; in the early 1900s, we obtained 100 barrels euqivalent of oil per barrel invested (EROEI of 100 to 1); today we are at about 15 to 1 globally and at 11 to 1 in the USA.

Donald Trump and his administration have been at the receiving end of passionate denounciations and scorn from many opinion leaders in the media. At the same time Trump’s approval rating among American voters has ranged between 50% and 60%. Here’s a statistical sketch of this American riff-raff and why they may support Trump.
Fully 35% of Americans do not have enough money to live comfortably (english: they can’t make ends meet). That’s more than 110 million people. These Americans have to supplement their cost of living with credit card debt. The Urban Institute reports that this same proportion of Americans (35%) have debt in collections (180 or more days past due). On average, the households that carry credit card debt are over $16,000 in the hole, paying an average interest rate at 16.1% (that’s $2,600 per year just in interest). Continue reading
Suppose you lived in a community where an old but well maintained bridge connected two river banks, enabling people and goods to move across. The bridge would represent a piece of community wealth, although its existence would only marginally impact the community’s ‘GDP’. Now suppose someone proposed to boost the community’s economic activity (GDP) by blowing up the bridge and building a new one. Continue reading
Yesterday I saw a brief speech by Leonardo di Caprio imploring people to vote – not for the candidate who ignores science. He was talking about the scientific consensus on global warming and mentioned that 97% of all scientists agree that global warming climate change is a man-made phenomenon. This 97% consensus figure is so compelling, it is only fair to explore where it came from.
Where “97% consensus” comes from
One Margaret Zimmerman conducted an opinion survey in 2008. The “survey” consisted of a two-question online questionnaire sent to 10,257 “earth scientists” (?), of whom 3,146 responded. Continue reading

In the aftermath of last week’s Brexit referendum many denounced the English vote with a mix of derision and indignation: the old and the uneducated crowds destroyed the European dream for everyone else. But would democracy be better if it were restricted to the best educated segment of the population? Let’s consider the idea of “wisdom of crowds.” This mysterious and utterly fascinating concept suggests that humanity evolved to be collectively intelligent and that the crowds tend to be more intelligent than the most intelligent of its members. If you have not yet come across this, prepare to be amazed (and keep an open mind): Continue reading
In an interview with Germany’s always fairly balanced Bild, NATO secretary general Jens Stoltenberg said that NATO can and must react to cyber-attacks, including with conventional military weapons, and that the 28 NATO member states will likely declare the cyberspace as an operational war zone. This makes total sense and all that’s missing from the interview is the reassurance that we’ve always been at war with Eurasia. I could not resist a repost here of my April 2014 article titled,
