"With regard to food or fuel, most of the corn that's used in this is not for people anyway. It's for animal feed."

The grain is being diverted from the human food chain. People eat the animals fed by that grain. Amazing.

It is unbelieveable to me that conversion technologies (CTs) - like gasification, pyrolysis, and anaerobic digestion - were totally missing from your articles about biofuels. The feedstock - municipal solid waste that is not otherwise recycleable.

Using CTs we can cleanly produce significant quantities of biofuels and green chemicals, while cogenerating electricity. At the same time we will be reducing our need for landfills - which will reduce ghg and a major source of ground and air pollution.

This is happening. CTs already exist in Japan and Europe. Los Angeles has passed a comprehensive 20-year plan called "RENEW L.A." that will utilize CTs to cleanly convert 75-85% of its waste that is not currently being recycled into green electricity and biofuels. L.A.'s Public Works and Sanitation utilities are already developing outreach programs and RFPs for construction of facilities.

Forget all the drawbacks of cultivating feedstock - let's extend our recycling efforts by using CTs. Doing so will reduce urban blight significantly.

CTs can also be used to convert agricultural and forestry waste.

An overall very good summary. 2 quick points-

biodiverisity is right- essentially all grain is for human consumption- 90% is wasted going through the guts of chickens, cows, and pigs

you won't be surprised that I say we do away with all subsidies- if the fuels are efficient they should be able to compete on their own

Barclay's article on biofuels development in Central America and Brazil's role therein was quite informative and thorough, and I'll be referencing it my own blog.  The only thing she left out are the efforts of the UN Economic Commission for Latin America & the Caribbean (ECLAC/CEPAL) to help the Central American nations design their biofuels and related policies.

The above link is a company that sells algae that grows in smoke stacks. This is another carbon negative biomass source that although may not be able to scale super large, will still play a significant role.

Thanks Scott good post

and thanks to grist for working on the series

Hi,
I've been wondering about this since a friend pointed it out. Maybe it's just my ignorance of agriculture.
If bio fuels are made out of plants. Where will the water to water them will come? Won't that drain our drinking water reserves?
Thanks
Nacho
