67 Reasons why wind turbines cannot replace fossil fuels
Source: Leonard, T. 2012. Broken down and rusting, is this the future of Britain’s ‘wind rush’? Preface Last updated 2023-10-20 The most important problem to be solved is electrifying transportation, otherwise how can you deliver the 30,000 parts of a … Continue reading
Fusion is already running out of fuel
Source: Khan A (2021) Nuclear fusion: building a star on Earth is hard, which is why we need better materials. The Conversation. Preface. Of all the hundreds of obstacles fusion has yet to overcome, its death knell could be as … Continue reading
Do you want to eat, drink, or fly?
Preface. In this post the New York Times writes about renewable airplane fuel from corn ethanol, and questions whether there is enough water and a few other problems. First I’m going to summarize their issues with this, and then follow … Continue reading

David Fridley, LBNL scientist, on why alternative energy won’t save us
Preface. I’ve sought out David Fridley’s insights since I first met him in the Oakland Peak Oil group that formed in 2004. That group eventually dissolved, but David’s expertise is still sought out by many of us following energy decline. … Continue reading

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

Why it is hard to replace diesel with biodiesel
Biodiesel is the great hope, our main hope, the only renewable fuel of all the many options, and the closest to the diesel essential for rail, trucks, and ships to do the actual work of civilization. The U.S. produces over … 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

Biogas from cow manure is not a solution for the energy crisis
Preface. Smil’s article about biogas sums up why it won’t contribute to energy shortages as fossils decline. Biogass doesn’t scale and is easy to muck up. Hayes (2015) also makes this case, pointing out that even if every ounce of … Continue reading
