Why we aren’t mining methane hydrates now — or perhaps ever
Preface. Methane hydrates are far from being commercial, and probably always will be. Scientists and companies have been trying to exploit them since the first energy crisis in 1973 to no avail. Nor are they likely to trigger a runaway … Continue reading

Why fusion power is Forever Away
Preface. When my husband Jeffery Kahn was a science writer at Lawrence Berkeley National Laboratory, we became friends with several astrophysicists who used to joke about how fusion was 30 years away and always would be. If world peak oil … Continue reading

Why no single or combination of alternative energy resources can replace fossil fuels
Preface. This 2002 paper is still true today. There simply are no renewable replacements for the fossil fuels that power our civilization. If only scientists could violate the laws of thermodynamics and physics the way capitalistic crooks cheat, like Bernie … Continue reading

Utility scale energy storage doesn’t scale up: limits to minerals and geography
Preface. Natural gas is finite, but aside from (pumped) hydropower, natural gas is the main way wind and solar are balanced now. Therefore, a tremendous amount of energy storage will be needed in the future as natural gas declines. And … Continue reading
Not enough rare metals to scale up solar power
Preface. Sunshine may be free, but the materials to make solar contraptions sure aren’t. Since sunshine arrives in a diluted form, vast expanses of solar photovoltaic panels will be needed to produce the world’s 24,000 Terawatt hours of electrical … Continue reading

What are rare earth metals and how are they used?
Preface. After oil, the main feature of new products will be drastic simplification. The re-use of existing stuff. Lack of precision machine tools as they rust away. Back to basics: wood, iron, and clay. Yet every high-tech object depends on … Continue reading

The Invisible oiliness of everything
Preface. Even a simple object like a pencil takes hundreds of actions and objects requiring fossil energy to do and make. Not electricity. This is on of many reasons why wind, solar, or other contraption that make electricity can’t replace … Continue reading
Can Geothermal power replace declining fossil fuels?
Preface. Today the electric grid stays up because of months of backup power from natural gas, coal, and uranium. Most of all natural gas because it can quickly balance wind and solar as they suddenly appear or die out. Natural … Continue reading

Movie review of Michael Moore’s “Planet of the Humans”
Preface. This documentary was made by Jeff Gibbs, a writer and environmentalist, with Michael Moore as the executive producer. This movie is worth watching, and an entertaining and quick way to understand why rebuildable “renewables” are neither green or a … Continue reading
