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

Posted on June 30, 2020 by

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 →

Why studies come up with different Energy Returned on Invest (EROI) results: can it be fixed?

Posted on March 21, 2017 by

[ There are many issues with biofuels beyond their trivial to negative energy return on investment (EROI). In Peak Soil I point out that current industrial farming techniques are destroying topsoil about 15 times faster than pre-fossil fuel economies — … Continue reading →

Large agribusiness gets corporate welfare via illegal ethanol subsidies

Posted on October 22, 2014 by

What more proof is needed that the Energy Returned on Energy Invested of ethanol is negative?  They’re losing money and getting corporate welfare to keep the scam going, meanwhile destroying prime topsoil, poisoning the land with pesticides, and eutrophying the … Continue reading →
