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 make up for declining fossil fuels?

Preface. Geothermal power plants are cost justified only in places where volcanic or tectonic activity brings heat close to the surface, mainly in “ring of fire” nations and volcanic hot spots like Hawaii.   Even then drilling can only be done … Continue reading

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

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

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
