The CSM article mentioned here shows that on a global scale, food is not supply limited, but that doesn't mean reductions in supply due to today's biofuels don't cause price increase and land-use change. They do until we fix the system.
The economics of supply and demand are impossible to deny. As a result we need to regulate biofuels so that their feedstocks don't drive these impacts.
This issue of Science is full of articles on forestry. Critical reading for anyone wondering about using woody biomass for energy
This looks interesting. While I like the requirement to provide improvements across the board, there should also be incentives for improvement above the standards.
Couldn't agree more with the headline and the study apparently points out that renewable fuel policies need to look at the lifecycle GHG emissions.
Having personally spent time ripping kudzu out of trees and bushes, I like the idea doing anything that would beat this plant back, but this treads close to the line of promoting invasive species to make biofuel, which we simply shouldn't do.
Patrick Mazza continues with useful and insightful coverage of biofuels issues.
This is a great resource with links to much of the current back and forth on GHG emissions from indirect land use change from biofuels.
This is a very thoughtful op-ed by one of the preminent thinkers about low carbon fuels and policies to advance them.
This post covers LS9 and Amyris, two of companies that developing new biofuel molecules, different from ethanol and biodiesel. As I mentioned in my New Year's post expect to see a lot of action on this front in the year a head.
As usual, Cai Steger stiches things together in a helpful way. This time talking about the importance of CHP to reducing the cost and GHG emissions from ethanol production.
Gulf Ethanol claims to have developed something called a "vortex implosion disintegrator," that turns biomass into cellulose powder. What happens to the other parts of the biomass? Not clear. However, pre-processing is one of the important challenges to c
Don't know how I missed this when it first aired on Oct 17, but this is well worth a watch.
Entertaining and a little educational. Worth a watch.
