Is Obama’s New Energy Security Trust Trustworthy?

Ozzie Zehner Green Illusions White House Energy Security Trust

President Obama’s Energy Security Trust, announced this morning, expands offshore oil drilling operations in order to provide a tax base for alternative energy, which will in turn lead to economic growth.

The irony in the president’s proposal is that it exposes how alternative technologies rely on economic arrangements that are themselves reliant on fossil fuels. And, if they work as advertised, these energy technologies will spur the kind of growth that will increase pressure to extract and burn fossil fuels well into the future.

What You Don’t Know about Inequality

 

Inequality in American society is apparently not well understood by the general public. This motion infographic renders:

1) What people think a fair income distribution looks like

2) What people think income distribution really is

3) Actual income distribution in America

Wealth ultimately arises from natural resource extraction, primarily fossil fuels. So, this film offers a launching point to think about how the earth’s resources should be shared among its inhabitants. Also, how does income inequality affect rates and forms of consumption, investment, growth and other stresses on the non-human world?

Why Biochar Isn’t Green

Ozzie Zehner Green Illusions Biochar UTNE Reader

UTNE Reader | Ozzie Zehner

While burning biochar, a rebranded term for charcoal, is less harmful than burning firewood, the fuel source would have a negative impact if produced on a large scale. “Green Illusions,” by Ozzie Zehner, is a practical, environmentally informed and lucid book that persuasively argues for a change of perspective on dealing with climate change. When contemplating alternative energy sources, such as biochar, one must understand its advantages as well as its limitations. The following excerpt comes from chapter 3, “Biofuels and the Politics of Big Corn.”

Even as legislators flood cellulosic ethanol and other biofuel initiatives with funding, some biofuel opportunities go over­looked, mostly because they are boring in comparison. For in­stance, wastewater treatment facilities release methane, the main component of natural gas, but more than 90 percent of Amer­ica’s six thousand wastewater treatment plants don’t capture it. As mentioned earlier, methane is a major greenhouse gas liability since its venom is more potent than that of carbon diox­ide. The sludge output of the average American yields enough power to light a standard compact florescent light bulb without end. So skimming the methane from an entire city’s wastewa­ter would not only prevent harmful emissions but also would produce enough power to run the entire wastewater operation, perhaps with energy to spare. Although not a large-scale solu­tion, captured biogas is a reminder of the modest opportunities to draw upon biofuels without advanced technology.

Another biofuel product that is now starting to gain more at­tention is a convenient replacement for firewood. Burning fire­wood directly is a relatively dirty practice, emitting dangerous particulates, hydrocarbons, and dioxins. In poor countries, the soot from firewood, waste, and dung kills about 1.6 million peo­ple per year. It’s also a local climate changer; soot darkens air and darker air absorbs more solar radiation. But there’s another way to extract energy from wood besides burning it—one that was widely employed before the Industrial Revolution but has since fallen by the wayside—charcoal (recently rebranded as biochar). When processors heat wood above 300 [degrees celcius] with limited oxygen, in a process called pyrolysis, it spontaneously breaks into three useful fuels: biochar, heavy oil, and flammable gas. In addition to its use as a fuel, farmers can till their soil with bio­char in order to reduce methane and nitrous oxide greenhouse-gas emissions. Archaeologists uncovered ancient South Amer­ican settlements in which buried charcoal has been sequestered for thousands of years, lending interest to the concept of using biochar as long-term storage for excess carbon.

In all, there may be many benefits to implementing biochar tech­niques in place of burning wood and waste for fuel directly. But this doesn’t make biochar a global solution. Cornell researcher Kelli Roberts points out that large-scale biochar production, as envisioned by some eager biofuel productivists, could yield unintended consequences. As with other biofuel methods, if producers clear virgin land to grow biochar inputs such as trees and switch grass, the process could ultimately do more harm than good. Alternately, if producers grow biochar crops on ex­isting farmland, farmers may be forced onto new land, yield­ing the same negative effects on virgin land plus the added risk of local food price instability. And then there is the hitch with any method for increasing available energy supply—it inevi­tability leads to growth, expansion, and increasing energy con­sumption—a reminder that smart upgrades in energy practices for local communities may not have the same positive effects if implemented on a larger scale.

Windy Assumptions

Like the 28 governors and numerous environmental groups currently scrambling to extend wind power subsidies, I long assumed that wind turbines and solar cells offset fossil fuel use. They probably don’t.  >> read the article
