Why liquefied coal (CTL) and natural gas (GTL) can’t replace oil
Preface. Here are just a few of the reasons why we aren’t likely to convert enough coal to diesel to matter as oil decines (see Chapter 11 Liquefied Coal: There Goes the Neighborhood, the Water, and the Air for more … Continue reading

Biocoal from food waste and sewage
Preface. This probably doesn’t have a net energy gain because of the energy to move waste and sewage to a common facility, and then transport these wastes from numerous places to the factory where biomass is converted to coal using … Continue reading
Walter Youngquist: Geodestinies Coal
Preface. Before the excerpt from Geodestinies, I thought an introduction to how coal is formed would be worthwhile, especially since I still thought it was the “once-popular explanation” below (Cottier 2021 How Ancient Forests Formed Coal and Fueled Life as … Continue reading

USGS: Half of U.S. Coal runs out in 35 years, not 250
Preface. The USGS did a survey of coal in the U.S. in 1974 and announced that America had 250 years of coal left. In 2007, the National Research Council wrote a report suggesting 100 years was more likely due to … Continue reading

Steam engines. Exergy power. and work in the US
Preface. At some point of fossil fuel decline future generations will be tempted to build steam engines again, and perhaps just as in America initially they’ll use wood to fuel the engines, since coal will be scarce at some point … Continue reading
Vaclav Smil: from wood to coal to oil, energy transitions take a long time
Preface. This post has a shortened, reworded, and heavily commented on article from Scientific American in 2014. You can also see two much longer articles about energy transitions by Smil from n 2008 and 2010 here: A transition from fossil … Continue reading
