Dozens of reasons why solar power can’t replace fossil fuels

Preface. Last update 2024-6-3. 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

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

Negative energy return of solar PV in Northern Europe

Preface.  I once yanked this paper after huge blow back, almost as bad as nuclear proponents, 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 … 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

Renewable costs don’t include transmission & energy storage backup from Nat Gas & Coal plants

Preface. Wind and solar advocates don’t include transmission and backup costs in their net energy and cost calculations. But without fossil backup, the electric grid will come down due to lack of storage. There is almost nowhere left to put … Continue reading

Concentrated Solar Power is dying out in the U.S.

Preface.  Concentrated Solar Power (CSP) contributes only 0.06 % of U.S. electricity, mainly in California (64 %) and Arizona (24 %) because extremely dry areas with no humidity, haze, or pollutants are required. Of the 1861 MW power they can … Continue reading
