A new plant in Tulare County, California, is in the poop power business: it turns ample dairy cow manure from the area into ethanol (and water for crops).
The massive diversion of grain to fuel cars has helped drive up food prices, leaving low-income consumers everywhere to suffer some of the most severe food price inflation in history. As of mid-2012, world wheat, corn, and soybean prices were roughly double their historical levels.
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?
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. Gasoline use in the United States is falling, and the trends already driving it down are likely to continue into the future, making both the mirage of beneficial biofuels and the construction of a new pipeline to import incredibly dirty oil seem ever more out of touch with reality.
2012 continued a disturbing trend in global agriculture: grain consumption outweighed production, forcing a drawdown in reserves.
Cooking’s a killer activity in the developing world: millions die from smoke inhalation, and forests are stripped bare as billions gather wood for their stoves (or for making charcoal for cooking). Take a look at five organizations working to address these multiple challenges.
There is a great deal of controversy about the wisdom of diverting a significant percentage of the US corn crop into the production of ethanol to fuel cars. Something like 25-30% of the crop will probably be used this way in 2011 which sounds alarming in the face of global food supply issues that have […]
By Lester R. Brown As oil and natural gas reserves are being depleted, the world’s attention is increasingly turning to plant-based energy sources. These include food crops, forest industry byproducts, sugar industry byproducts, plantations of fast-growing trees, crop residues, and urban tree and yard wastes—all of which can be used for electrical generation, heating, or […]
By Lester R. Brown At a time when excessive pressures on the earth’s land and water resources are of growing concern, there is a massive new demand emerging for cropland to produce fuel for cars—one that threatens world food security. Although this situation had been developing for a few decades, it was not until Hurricane […]
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 […]
The 107 million tons of grain that went to U.S. ethanol distilleries in 2009 was enough to feed 330 million people for one year at average world consumption levels. More than a quarter of the total U.S. grain crop was turned into ethanol to fuel cars last year. With 200 ethanol distilleries in the country […]
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 […]
