Dozens of reasons why solar power can’t replace fossil fuels
Preface. Last update 2022-9-2. All solar (and wind) do is add to the giant bonfire of burning fossil fuels — which still provide two-thirds of the power for the electric grid. Electricity is just a fraction of how we use … Continue reading

Solar panels in the Sahara could cause global warming
Preface. Adding tens of thousands of square miles of solar panels to replace fossil fuels could cause climate change and heat up the planet. Of course this is a fantasy, dust storms would scour the panels rendering them useless, with … Continue reading

The Next Big Thing: Distributed Generation & Microgrids
Preface. Last updated 2022-9-5 The first article below explains what microgrids will look like in the future. But first a brief look at what a microgrid is, as Angwin explains in her book “Shorting the Grid. The Hidden Fragility … Continue reading
Negative energy return of solar PV in Northern Europe
Preface. I once yanked this paper after huge blow back, but in the past few years, I have no reason to doubt Ferroni and Hopkirks methods, boundaries, or conclusions, so I’m putting this post back. If you automatically dismiss this … 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

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

Pedro Prieto: many solar panels won’t last 25-30 years, EROI may be negative
Preface. Pedro Prieto and Charles Hall wrote the definitive book on the EROI of solar power, “Spain’s Photovoltaic Revolution. The Energy Return on Investment” and has built many commercial facilities himself and witnessed the failure of solar panels long before … Continue reading
Want to go off-grid? You might need hundreds of Tesla batteries
Preface. Although you may not be as far north as Victoria, British Columbia (48.4 latitude), you’d ideally want to be at 30 degrees or less latitude from the equator to even consider the expense of off-grid solar power. And even … Continue reading
Why is nearly all solar power built where subsidies are the highest?
If solar net energy return is as high as some solar advocates claim, why does solar need any subsidies? And not just U.S. subsidies, it’s subsidies on top of subsidies when you add in that we’re buying Chinese government subsidized … Continue reading
