Tons of fiber-reinforced plastics ... lack of storage

"A largely ignored issue is how to deal responsibly with the environmental hazards presented by old rotor blades disposed of at the end of their operational lifecycle. ‘The 100,000 wind turbines operational at the end of 2007 contain about 660,000 tonnes of fibre-reinforced plastics, that at some time in the future will end up as a huge chemical waste pile. By 2017 the number of operational turbines worldwide will perhaps have grown to 400,000 units, which corresponds to about 6.6 million tonnes of fibre-reinforced plastics waste. The recycling of steel and non-ferrous metals is a relatively well-known straight-forward process, but this essential know-how is far more limited for fibre-reinforced future plastics waste’, Molly [DEWI (German wind energy institute) managing director Jens Peter Molly] concluded. ...

"Increasing renewable energy systems, while sharing an electric power generation and supply infrastructure, raises the need to develop sufficient energy storage capacity. This is essential to balance fluctuating power feed-in from these inherently variable power sources. Among several options being researched in Northern Germany is adiabatic (no heat exchange) compressed air energy storage in underground salt formations, and especially in naturally formed caverns. These structures, which have an average size of 500,000m3, offer a storage capacity between 2.02–2.73 kWh/m3. Total capacity for adiabatic energy storage in Northern Germany is estimated at 800–2500 GWh. The energy storage efficiency depends on the technology applied and is estimated in the range of 50%–70%. However, there are competing uses for these caverns – underground CO2 capture and the long-term storage of nuclear waste."

Abstract: Climate change mitigation policies tend to focus on the energy sector, while the livestock sector receives surprisingly little attention, despite the fact that it accounts for 18% of the greenhouse gas emissions and for 80% of total anthropogenic land use. From a dietary perspective, new insights in the adverse health effects of beef and pork have lead to a revision of meat consumption recommendations. Here, we explored the potential impact of dietary changes on achieving ambitious climate stabilization levels. By using an integrated assessment model, we found a global food transition to less meat, or even a complete switch to plant-based protein food to have a dramatic effect on land use. Up to 2,700 Mha of pasture and 100 Mha of cropland could be abandoned, resulting in a large carbon uptake from regrowing vegetation. Additionally, methane and nitrous oxide emission would be reduced substantially. A global transition to a low meat-diet as recommended for health reasons would reduce the mitigation costs to achieve a 450 ppm CO2-eq. stabilisation target by about 50% in 2050 compared to the reference case. Dietary changes could therefore not only create substantial benefits for human health and global land use, but can also play an important role in future climate change mitigation policies.

Richard Silverstein on the hounding out of Chas Freeman

"Seems to me we've just completed eight years of an administration that ran from the truth tellers as fast as their feet would carry them. Similarly, the lobby wants no truth tellers when it comes to devising US policy toward Israel. It wants sycophants, yes-men, pols who know how to line up in a straight line. We can see how well this policy worked for George Bush. And it won't work for an administration that wants to act as a more honest broker, rather than a cheerleader or enabler of one side's bad habits."

(Ironically, many Jews were automatically suspect during the blacklist days of the 1940s and '50s, and now they are the ones threatening careers to silence honest analysis and dissent. Similarly, it is disturbing indeed that Israel seems to have taken the lesson of the Warsaw Ghetto not as "never again" but as "Now it's our turn".)

Chas Freeman on his hounding out from the NIC

... The libels on me and their easily traceable email trails show conclusively that there is a powerful lobby determined to prevent any view other than its own from being aired, still less to factor in American understanding of trends and events in the Middle East. The tactics of the Israel Lobby plumb the depths of dishonor and indecency and include character assassination, selective misquotation, the willful distortion of the record, the fabrication of falsehoods, and an utter disregard for the truth. The aim of this Lobby is control of the policy process through the exercise of a veto over the appointment of people who dispute the wisdom of its views, the substitution of political correctness for analysis, and the exclusion of any and all options for decision by Americans and our government other than those that it favors.

There is a special irony in having been accused of improper regard for the opinions of foreign governments and societies by a group so clearly intent on enforcing adherence to the policies of a foreign government – in this case, the government of Israel. I believe that the inability of the American public to discuss, or the government to consider, any option for US policies in the Middle East opposed by the ruling faction in Israeli politics has allowed that faction to adopt and sustain policies that ultimately threaten the existence of the state of Israel. It is not permitted for anyone in the United States to say so. This is not just a tragedy for Israelis and their neighbors in the Middle East; it is doing widening damage to the national security of the United States.

The outrageous agitation that followed the leak of my pending appointment will be seen by many to raise serious questions about whether the Obama administration will be able to make its own decisions about the Middle East and related issues. I regret that my willingness to serve the new administration has ended by casting doubt on its ability to consider, let alone decide what policies might best serve the interests of the United States rather than those of a Lobby intent on enforcing the will and interests of a foreign government. ...

If you let big wind through the door, you can't stop anything else

Obama overrides Bush rule on Endangered Species Act, by Jim Tankersley. Los Angeles Times, March 4, 2009:
President Obama on Tuesday overrode the Bush administration on a key step in applying the Endangered Species Act, restoring a requirement that federal agencies consult with experts before launching construction projects that could affect the well-being of threatened species.

Environmentalists said reinstating the requirement blocks the Army Corps of Engineers, the U.S. Forest Service and others from “nibbling away” at crucial wildlife habitat. Business and industry groups, on the other hand, warned that Obama’s action could hamper road-building and other projects that would help jump-start the economy.

Bush’s rule change, finalized in December, allowed federal agencies to determine on their own if projects would jeopardize endangered species, instead of consulting with expert biologists, as had been required for the last three decades. ... Obama made such consultation mandatory. ...

Industry lobbyists said Obama’s decision to mandate the consultations would add “red tape” to infrastructure projects funded by the economic stimulus bill. “This directive throws the brakes on projects,” said William L. Kovacs, the U.S. Chamber of Commerce’s vice president of environment, technology and regulatory affairs.

Even clean energy plans, such as wind farms, could be slowed down, said Michael D. Olsen, a former Bush Interior official who now lobbies for energy interests at Bracewell and Giuliani. “It’s not just projects that folks would term non-green,” he said. “It’s the green projects too.”
A few things should be noted. First, "red tape" in this case is what the civilized call "laws". Second, if a project threatens endangered species, it is not "green".

Third, it is not surprising that groups like the Sierra Club, Environmental Defense Fund (EDF), and Natural Resources Defense Council (NRDC) praise this return to the rule of law. At the same time, however, they join industry lobbyists such as Bracewell & Giuliani in promoting industrial wind energy development in rural and wild places. NRDC and EDF completely ignore adverse impacts in their praise for big wind. EDF even does PR work for individual companies. Only the Sierra Club recognizes that "wind projects tend to be large industrial developments with inevitable adverse impacts". Many of its local chapters actively oppose giant wind projects. Yet they also unquestionably accept the industry pitch that "Wind power is a reliable, clean, renewable resource that can help reduce our dependence on polluting fossil fuels (coal, oil, and natural gas) and nuclear power for electricity". The wind is anything but reliable (for providing real-time power in response to the needs of the electric grid), you can hardly call 400+-ft-high generators clean -- along with their associated clearing, foundations, roads, substations, and transmission lines -- and, due to wind's high variability, intermittency, and unpredictability, it has not been shown to reduce the use of other sources.

Regarding industrial wind energy, environmental groups need to reassess what side they're on. As they welcome Obama's restoration of protection for endangered species, they should restore their own perspective: They should stop acting as agents for an industry whose green credentials have turned out to be a sham and return to fighting to protect the natural world. Industry has its defenders. Nature needs its defenders to get back on track.

Wind energy executive gets elected to state legislature, pushes laws to benefit wind energy

The Feb. 26 St. Paul (Minn.) Legal Ledger included a profile of freshman state representative Andrew Falk:
In 2005 he started his own wind-power company, Knight Energy, and has been a frequent presence at the Capitol in recent years lobbying for legislation supporting eco-friendly power sources. In part because of Falk’s advocacy work, his rural district has become something of an epicenter for the development of renewable energy sources, with wind farms and turbines dotting the west-central Minnesota prairie landscape. ... The freshman legislator from Murdock now expects to expand this work through his post as vice chair of the Energy Finance and Policy Division.
There was no mention in the piece that Falk divested his stake in Knight Energy before becoming a lawmaker. As far as I could determine, Falk is still invested in Knight Energy.

The usual ethics problem for legislators is their becoming lobbyists for industries soon after steering laws to their benefit. Here we have a lobbyist becoming a legislator and promising to work for laws benefiting his company. Sheesh!

Denmark: more per-capita carbon emissions than U.S.

According to Ralph Sylvestersen, Special Adviser for maritime regulation and international affairs at the Danish Maritime Authority and committees at the U.N.'s International Labor Organization and International Maritime Organization, and principal ship surveyor, Greenland, Denmark easily surpasses the United States in per-capita carbon emissions. Click the title of this post for his original piece.

Denmark boasts a high level of growth but steady energy consumption. Sylvestersen notes that while shipping is included in the gross domestic product, its energy consumption isn't included in national figures. Denmark owns 10% of the world's shipping fleet, including the high-speed container ships of the Maersk Line and others. In 2006, the shipping industry used more than twice as much energy as the entire country's domestic consumption.

Recalculating with figures from the Danish International Shipping Industry, Danish per-capita carbon dioxide (CO2) emissions are 32.5 tons/year. That compares to 19.5 tons/year in the United States.
