Deforestation in the news

Preface. I wrote in “Life after fossil fuels” that as energy declined, it would be hard to cut down distant forests with limited oil supplies.  I thought this because even in Britain, so denuded of trees people turned to filthy … Continue reading

800 scientists: Burning forests for electricity & heat releases more 1.5x more CO2 than coal, 3x more than natural gas

Preface. The 2015 Paris climate change agreement states that burning biomass is carbon neutral. Not true. Over 800 scientists have written the European Parliament to tell them that burning wood for heat or electricity emits 1.5 x more CO2 than … Continue reading

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

Preface.  Just when civilization is decades from returning to wood as the main energy source (due to peak oil in 2018), climate change is allowing invasive beetles to survive winters and kill trees, with drought and wildfires increasing the damage. … 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
