Wind, solar, and natural gas are driving nuclear power out of business

Posted on February 28, 2020 by

Preface. I’m no fan of nuclear power because we may already be at peak uranium, there’s nowhere to store nuclear waste, and a spent nuclear pool fire could harm millions of people. But renewable wind and solar and natural gas … Continue reading →

When wood is again our main energy source, how long will it last?

Posted on January 23, 2020 by

Preface.  Just when civilization is decades from returning to wood as the main energy source (due to peak oil in 2018), climate change is allowing invasive beetles to survive winters and kill trees, with drought and wildfires increasing the damage. … Continue reading →
