Building a national super grid in America

Posted on December 3, 2024 by

Preface. Renewables are not evenly distributed.  Just 10 states have 80% of hydropower (Homeland Security 2011), 10 states produce 75% of wind power (EIA 2017), and 10 states produce 79% of solar power (CE 2020). With a national grid, instead … Continue reading →

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

Posted on June 6, 2022 by

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

Posted on December 23, 2021 by

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

Posted on November 28, 2021 by

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

Posted on June 16, 2021 by

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

Posted on March 5, 2021 by

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

Posted on February 21, 2021 by

  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 →

Renewables: not enough minerals, energy or time and mining is destructive

Posted on January 22, 2021 by

Preface. Electricity generating contraptions like wind and solar can’t replace the 50% of oil used in global manufacturing, because they can’t generate the high heat needed, or run battery or catenary electric trucks as I explained in “When Trucks Top … Continue reading →
