New Studies Support Cellulosic Ethanol

A team of researchers led by Jason Hill and David Tilman at the University of Minnesota have published an interesting assessment of the health costs of both greenhouse gas and fine particulate matter from corn ethanol, gasoline and cellulosic ethanol. The study is available in the Proceedings of the National Academy of Sciences early release for Feb. 10. The conclusion is favorable to cellulosic ethanol: The benefits of shifting from gasoline and the current generation Read More >

Comparing Energy Sources

Stanford University Professor Mark Z. Jacobson recently published a new paper in the journal Energy & Environmental Science, “Review of solutions to global warming, air pollution, and energy security.” According to Stanford News Writer Louis Bergeron, Jacobson has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water Read More >

Yes, Virginia

One of the most strikingly circular arguments put forward to support inclusion of current estimates of indirect land use change emissions in both California’s Low Carbon Fuel Standard and the EPA’s Renewable Fuel Standard Life Cycle Assessment is that these estimates are so large. The University of California Berkeley Letter to EPA from Michael O’Hare et al. and the previous letter to California’s Air Resources Board by the same group (Mark Delucchi et al.) are Read More >

Midnight Rule

The EPA apparently missed the statutory deadline (Dec. 19) to publish the Notice of Proposed Rulemaking for the Renewable Fuel Standard. The Bush administration last summer announced that it would not promulgate new rules during its final 30 days, in order to stay away from “midnight rulemaking.” That self-imposed deadline (Dec. 20) also passed. The rule is said to be a victim of lobbying on the part of the biofuel industry and environmental groups. Marianne Read More >

Discounting the Future of Biofuels

It appears that global leaders’ faith in energy technologies that can reduce greenhouse gas emissions compared to oil is waning, particularly for biofuels, as reported in GreenInc. Respondents to the survey, which included 1,000 environmental experts, ranked energy conservation and efficiency technologies as having the greatest potential impact, both short- and long-term. Some 44 percent of respondents also said they expect that the current economic crisis will hinder progress toward an effective international climate agreement. Read More >
