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

GAO on why ethanol, and other non-drop in fuels, face pipeline & installation at service station challenges
[The challenges that ethanol faces in being put into new or modified pipelines and added to gas stations are issues faced by all alternative fuels (methanol, CNG, LNG, DME, diesohol, CTL, hydrogen, and so on) in a transition from gasoline … Continue reading
