Distribution – why it is so hard to add E15 or E85 at a gas station

Preface. One of the huge hurdles to shifting from oil to “something else” is the chicken-or-egg problem of no one buying a new-fuel vehicle with few places to get it, so few are made, so service stations don’t add the … Continue reading

Can Geothermal power replace declining fossil fuels?

Preface. Today the electric grid stays up because of months of backup power from natural gas, coal, and uranium.  Most of all natural gas because it can quickly balance wind and solar as they suddenly appear or die out. Natural … Continue reading

The U.S. May Soon Have the World’s Oldest Nuclear Power Plants

Preface. This is nuts. Sea level rise threatens many nuclear power plants and drought has shut plants down since they need cooling to operate. As nuclear reactor age, they require more intensive monitoring and preventive maintenance to operate safely. But … Continue reading

High-level nuclear waste storage degrades faster than thought

Preface. Burying nuclear waste ought to be a top priority, now that it appears peak oil may have happened in November of 2018 (Patterson 2019) and perhaps even sooner if covid-19 crashes the world economy (Tverberg 2020). It won’t happen … Continue reading

Concentrated Solar Power is dying out in the U.S.

Preface.  Concentrated Solar Power (CSP) contributes only 0.06 % of U.S. electricity, mainly in California (64 %) and Arizona (24 %) because extremely dry areas with no humidity, haze, or pollutants are required. Of the 1861 MW power they can … Continue reading

Oil consumption of containerships

Preface.  Since 90% of international goods move by ships, I was curious about how much fuel they burned.  It’s a lot: The very large container ship CMA CGM Benjamin Franklin above, which can carry 18,000 20-foot containers, carries approximately 4.5 … Continue reading

Building a national super grid in America

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
