Non-fossil energy contraptions

World Peak Uranium Production

Preface.  The World Nuclear Association estimates 90 years are left.  Today  67,500 tonnes of uranium are consumed a year world-wide and production in 2020 was 47,731 tonnes (WNA 2021). Sounds a bit peakish, thank goodness for stockpiles and the infinite … 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

SMR / Gen 4 nuclear reactors less safe & create even more toxic waste

  Preface. With climate change getting all the press and the coming energy crisis virtually no coverage, pro-nuclear forces are strongly pushing new nuclear plants as a way to lower CO2 emissions and deliver reliable power (but only baseload, they … Continue reading

Lithium-ion battery recycling, environmental impact, energy used

Preface. The future of both electric vehicles and utility-scale energy storage are depending on lithium-ion batteries because of their high energy-density, and even though lithium is limited, it’s about the only kind of battery being made for transport (because it … Continue reading

Climate change will damage energy infrastructure, costing trillions

Preface. Climate change and extreme weather will harm oil and gas exploration and production, electric power generation and increase energy demand due to sea level rise, heat, drought, floods, more storms, and blackouts.  Extreme heat and drought will force electric … 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

Bill Gates on why Electric Airplanes won’t fly

Preface. I wonder if Bill Gates has read my book “When Trucks Stop Running”? As he says in the article below: “The renaissance of electrification that we’re seeing in passenger vehicles unfortunately won’t likely adapted to heavier forms of transportation … 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

Diesel is finite. Trucks are the bedrock of civilization. So where are the battery electric trucks?

Last updated: 2023-1-21 Preface. Heavy-duty diesel-engine trucks (agricultural, mining, logging, construction, garbage, cement, 18-wheelers, and more) are essential for doing the actual work of our fossil-fueled civilization. Without them, no goods would be delivered, no food grown, nothing manufactured, no … Continue reading
