Food to Fuel… the Right Way [Infographic]

The phrase “food to fuel” often refers to production of corn-based ethanol or soy-based biodiesel… not exactly most efficient use of these commodities. But there are situations when food to fuel represents a smart use of resources: when that food will go to a landfill. While the capture of landfill gas has become more prevalent, why spend the money and other resources shipping it there? Why not just direct food waste to energy production?

Falling Gasoline Consumption Means US Can Just Say "No" to New Pipelines and Food-to-Fuel

Freeing America from its dependence on oil from unstable parts of the world is an admirable goal, but many of the proposed solutions—including the push for more home-grown biofuels and for the construction of the new Keystone XL pipeline to transport Canadian tar sands oil to refineries on the U.S. Gulf Coast—are harmful and simply unnecessary.

While the Gulf oil spill continues to dominate the headlines, and the green blog space (as it should… this is a calamitous, and potentially game-changing event), even a cursory scan of the green blogosphere shows that we’re not standing still in terms of keeping other stories out there. This is so important… it’s critical that […]

Driving Unsustainability: How GM planned for obsolescence

I’m coming to the conclusion that there’s very little that’s sustainable about the company known as GM. It’s frustrating and sad, because I was raised in the auto city and had family members who worked in the industry.  I even spent a summer at the GM Tech Center (working for then EDS as an intern […]
