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

University Art Removed after Irking Energy Executives

The University of Wyoming removed a sculpture that links coal use to climate change and beetle infestations after it upset University donors, according to a New York Times article and Green Blog post.

The idea behind the sculpture that appeared on the University of Wyoming campus about 16 months ago was simple but provocative: a swirl of dead wood and lumps of coal, intended to show the link between global warming and the pine beetle infestation that has ravaged forests across the Rockies.

But in a place like Wyoming, where the oil, gas and mining industries are the soul of the economy, some view such symbolism as a declaration of war.

Challenges Envisioning a Nuclear-Free Germany

Challenges Envisioning a Nuclear-Free Germany
Ozzie Zehner

Can Germany go Nuc Free? That’s the plan for 2022. But due to a phenomenon economists call “leakage,” a nuclear-free Germany may remain an illusion.

Bloomberg Businessweek reports that even though Germany plans to shut down its reactors, the country now pays $139 million monthly to import electricity, some of it from Czech nuclear plants:

With the remaining nine German reactors scheduled to go offline by 2022, no one seems more eager to step into the breach than the Czechs. They’re in talks with vendors to build two more reactors at Temelín, while planning new reactors at the aging Dukovany nuclear station and at least two other sites… “Nuclear is the answer,” says Roman Portužák, who is involved in drawing up the country’s energy strategy at the Czech Industry and Trade Ministry. “How fast, how many reactors we’ll build—that’s still under discussion, but we’re definitely moving in this direction.”

Germany also imports stored nuclear power via Austria. Indeed, building luxury cars is energy intensive.

Many Germans expect renewables such as solar and wind energy to take up the slack, but taxpayers are less keen about paying for them. Germany is in the process of slashing subsidies that have spurred renewable energy growth throughout the country.

Germany has also exported energy-intensive smelting and heavy industrial operations to China and other countries, which has gotten those energy inputs off Germany’s tally. But the resulting raw materials and components are then shipped back to Germany.

Germany’s awkward energy contortions point to the complex global challenges and fuzzy accounting that we face when developing energy policy in an interconnected world. Perhaps Germany can go low-energy only if others do not.

Are Electric Cars Carbon Free? Some Perspective on Plugging In

Chevy Volt, Ozzie Zehner

According to a report released today by the Union of Concerned Scientists, the carbon impacts of fueling your electric car depend on where you plug it in. The study, entitled “State of Charge: Electric Vehicles’ Global Warming Emissions and Fuel Cost Savings Across the United States,” points out that charging an electric vehicle with coal-based electricity yields the same carbon impact as at conventional car that gets 30 miles per gallon (mpg). If the charging power comes from hydroelectric and natural gas, prevalent in the pacific northwest, the carbon impacts of fueling an electric car equate to over 50mpg, according to the study.

These figures do not account for electric car fabrication footprints, which can have a much larger impact than the fueling cycle according to research from the National Academies of Science. In my recent piece in Christian Science Monitor, I argue:

Electric vehicles don’t eliminate the negative side effects of vehicular travel. They simply move the problems elsewhere – often to contexts where they become more opaque and difficult to address. When we start to exchange one set of side effects for another, the exchange rates become confusing. This opens a space for public relations firms, news pundits, environmentalists, and others to step in and define the terms of exchange to their liking.. The Union of Concerned Scientists report also doesn’t account for the methane released during natural gas fracking, the side effects of hydroelectric dams, and other externalities from energy production.

When the full environmental costs of electric car batteries and hardware are figured in, their green charm begins to appear suspect. Perhaps environmentalists should take a step back and reconsider whether they’d like to become spokespeople for the next round of ecological disaster machines.
