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

Are biofuels a sustainable and viable energy strategy?

[In 2000, Melanie Kenderine at the U.S. Department of energy stated that: “This nation has abundant biomass resources (grasses, trees, agricultural wastes) that have the potential to provide power, fuels, chemicals and other bio-based products” (136). That’s a good point … Continue reading

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

[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 vehicles are made, and service stations don’t add the … Continue reading

Biofuel distribution wastes valuable diesel fuel

Biofuels can’t use the existing refined petroleum distribution pipeline system, by far the cheapest way to move fuel — 17.5 times cheaper than truck, 5 times less than rail, 2.25 times less than barge, on average (Curley), so delivery of … 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
