EV cars only go half as far in freezing weather
Preface. Below freezing, li-ion batteries don’t perform as well. Consumer reports found that about half the driving range was lost. Perhaps this is why nearly half of PHEV/BEV vehicles are sold in balmy California, while the half of the states … Continue reading
Utility scale energy storage has a long way to go to make renewables possible
What follows comes from my book “When Trucks Stop Running: Energy and the Future of Transportation” , which is also where you’ll find the references backing up what I’ve written below. I often get letters from people about energy breakthroughs … Continue reading
Can Zinc batteries save us?
Preface: The New York Times had two articles about zinc air batteries in September 2018. Right now, finite natural gas is the dominant way of balancing unreliable, outright missing, or intermittent power from wind and solar. So other energy storage … Continue reading

Want to go off-grid? You might need hundreds of Tesla batteries
Preface. Although you may not be as far north as Victoria, British Columbia (48.4 latitude), you’d ideally want to be at 30 degrees or less latitude from the equator to even consider the expense of off-grid solar power. And even … Continue reading
Given the laws of physics, can the Tesla Semi really go 500 miles, and what will the price be?
Preface: Most people think that electric truck makers need to tell us the specs — the battery kWh, price, performance, and so on — before we can possibly know anything about their truck. But that’s simply not true. We know … Continue reading

How is California’s AB2514 experiment with utility scale battery storage coming along?
[ This is an excellent article by Tod Kiefer about tests of sodium-sulfur batteries, which are the only kind of battery for which there is enough material on earth to make. Battery electric storage is meant to “replace nimble, fast-ramping … Continue reading
