When wood once again becomes our main energy source, how long will it last?

Preface. Since we’re going back to wood as our main energy and infrastructure source after fossil fuels deplete, I thought it would be interesting to try to get an idea of how wood stacks up against other energy resources (below).   … Continue reading

Generating electricity with biomass at utility-scale in California limited to direct combustion in small 50 MW plants

Preface. It’s obviously much easier and more energy efficient to set logs on fire for heat and electricity than to turn them into ethanol.   Burning biomass can’t do much to solve our energy crisis.  To produce just 10% of … Continue reading

Steam powered farm tractors

Preface. Steam engines weren’t very efficient, 10 to 20% at best, which is why they went away beginning around 1920 when oil-powered engines came along.  At the very best steam engines for transportation reached 10 to 20% efficiency. They were … Continue reading

Charcoal for the high heat needed in manufacturing after peak oil

Preface. De Decker (2011) writes: “A large share of energy consumed worldwide is by heat. Cooking, space heating and water heating dominate domestic energy consumption. In the UK, these activities account for 85% of domestic energy use, in Europe for … Continue reading

European Power plants are burning American forests

Preface.   Incredibly, this article 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 … Continue reading

From wood to fossil fueled civilizations — the greatest tragedy mankind will ever know

[ These are my notes from this book about how we went from an organic sustainable economy to a temporary fossil-fueled one.  It’s one of the few books I’ve found that explains what life was like before fossil fuels in … Continue reading

Vaclav Smil on wood

[ I’ve extracted bits about wood from Smil’s book about materials below, read the book for the larger context.  Enormous amounts of wood were used in former civilizations with much smaller populations than today, so it’s clear we can’t go … Continue reading

Why studies come up with different Energy Returned on Invest (EROI) results: can it be fixed?

[ There are many issues with biofuels beyond their trivial to negative energy return on investment (EROI). In Peak Soil I point out that current industrial farming techniques are destroying topsoil about 15 times faster than pre-fossil fuel economies — … Continue reading
