Concentrated Solar Power is unreliable, full of glitches, & has a low energy return
Preface. Concentrating solar power (CSP) projects usually sprawl in a circle over several square miles and can cost over a billion dollars. They use mirrors and lenses to capture the high temperatures needed to efficiently produce or store electricity. Almost … Continue reading

Largest oil spill on earth: Plastics
Preface. There have been thousands of articles since I published this back in 2003. Today I read a surprising study that claims glass is more harmful than plastic because it is mined from rare materials and requires more fossil fuels … Continue reading
Dust Bowls
Preface. As if there weren’t enough to worry about, more Great Dust Bowls may be on the way. The irony is that some of it will likely be due to planting corn and soybeans to produce biofuels, yet another reason … Continue reading

The Texas electric grid outage
Preface. In February of 2021, millions of Texans and Mexicans lost electric power in a hard freeze. Oxer (2021) on the March 2 Power Hungry podcast, said that if the Texas grid had blacked out, it would have taken until … 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
Wanted: Math geniuses and power engineers to make a renewable grid possible
Figure 1. OPF solution of original seven-bus system with generator at bus 4 Preface. The U.S. electric grid produced 64% of electricity in 2019 with finite fossil fuels, and another 20% from nuclear power. Since fossil fuels and uranium are … Continue reading

How will 500,000 products made with fossils as feedstock & process energy be created post fossil fuels?
Preface. It is quite likely that after fossils are gone, plastics will no longer be made, since they are incredibly complex – PhDs in numerous fields make them possible – and most kinds have been around for only 50 years … Continue reading

Why wind and solar will cause more blackouts
Preface. Clearly fossil fuel plants need to be replaced with energy storage — batteries, pumped hydro, or compressed air. Many hours of backup power will be needed since, unfortunately, over two-thirds of total wind power in the U.S. happens outside … Continue reading

The Nitrogen Bomb: fossil-fueled fertilizers keep billions of us alive
Preface. There are two articles below that explain why natural gas fertilizers are keeping at least 4 billion of us alive today. If you’re interested in this topic, here are a few more to read: Erisman JW, Sutton MA, Galloway … Continue reading

Energy abundance depends entirely on the RATE of energy flow
Preface. Below are excerpts from two articles on why the FLOW RATE of oil is what matters for our fossil-fueled civilization. It’s like how, when filling up a bathtub, you want to turn the faucet on as high as it … Continue reading
