It’s final — Corn ethanol is of no use

Forbes / James Conca / 20 April 2014

The summary in the new report also states, “Increasing bioenergy crop cultivation poses risks to ecosystems and biodiversity” (WGIII).

The report lists many potential negative risks of development, such as direct conflicts between land for fuels and land for food, other land-use changes, water scarcity, loss of biodiversity and nitrogen pollution through the excessive use of fertilizers (Scientific American).

The International Institute for Sustainable Development was not so diplomatic, and estimates that the CO2 and climate benefits from replacing petroleum fuels with biofuels like ethanol are basically zero (IISD). They claim that it would be almost 100 times more effective, and much less costly, to significantly reduce vehicle emissions through more stringent standards, and to increase CAFE standards on all cars and light trucks to over 40 miles per gallon as was done in Japan just a few years ago.

Biofuels not all they’re cracked up to be, study finds

Common Dreams / Deirdre Fulton / 29 January 2015

ethanol“The quest for bioenergy at a meaningful scale is both unrealistic and unsustainable,” says a new report from the World Resources Institute that calls into question Western governments’ support for energy policies that encourage large-scale conversion of plants into fuel.

The study, “Avoiding Bioenergy Competition for Food Crops and Land” (pdf), published Thursday, is a wide-ranging look at the costs and benefits associated with producing plant-based energy, or biofuels. It finds that dedicating crops, such as corn or sugarcane, or land to generating bioenergy—as the U.S. and some European countries are already doing and aiming to do even more—is an inefficient use of the world’s natural resources.

Further, the report states: “[B]ioenergy that entails the dedicated use of land to grow the energy feedstock will undercut efforts to combat climate change and to achieve a sustainable food future.”

The Transition Framework

The Transition Towns movement aims toward veering away from excessive consumption – to deal with the conjoined problems of peak oil and climate change – but also in the belief that we may create an essentially more contented society, through building strong and resilient local communities. We will get to know our neighbours better, because we shall all need one another in the time to come.
