THIN FILM SOLAR PANELS

In a sign of things to come for corporate activism, The Gap, Timberland, Levi Strauss and Walgreens have just joined Whole Foods and Bed, Bath and Beyond in a boycott of petroleum products sourced from the notorious Alberta Tar Sands. As reported by Bob Weber of The Canadian Press, Federal Express has also adopted a policy that appears to lead toward joining the boycott.

The move comes just as scientists from the University of Alberta released a report on the mercury, arsenic, lead, cadmium, and nine other toxins from tar sands operations found in the Athabasca River system. In the meantime, environmentalists in the U.S. are raising the alarm over tar sands-related damage in Montana, where new road construction is planned in order to accommodate trucks hauling massive pieces of equipment to the Alberta tar sands.

In a last-minute race to the finish-line, the CEC has approved a staggering 2,800 MW (or 3 GW) of solar projects this month in California.

Among them are Tessera Solar’s 709 MW Imperial Valley Solar project in Imperial County (scaled down from 750 MW, by BLM request) and NextEra Energy’s 250 MW Beacon Solar Energy Project, the first large-scale solar-thermal power projects permitted in California in two decades.

During the same time, only one 760 MW fossil plant was approved: Mirant Corp.’s 760-MW Marsh Landing Generating Station.

This ratio of clean energy approvals to dirty energy approvals reverses the pattern over the last ten years. (more…)

Solar industry powerhouse Sunpower Corp. is busy creating new green jobs in the renewable energy sector, the latest endeavor being a group of contracts for a minimum of 20 megawatts in new solar installations for the U.S. Navy, Air Force, General Services Administration and National Renewable Energy Laboratory.  All together, SunPower estimates that the construction work will create about 1,000 new green jobs in the local communities where the installations are located, in addition to saving taxpayers money by helping to shift the U.S. military into a more stable, low risk form of energy.

The new projects also illustrate how the Obama administration has stepped up the pace of solar installations at government facilities. SunPower has been installing solar arrays at U.S. government facilities since 1999, for a total of 20 megawatts to date. That’s equal to the minimum amount of solar capacity that will be installed under the new contracts.

Following close on the heels of the U.S. Army, which just activated its first wind power project at the Tooele Army Depot in Utah, the U.S. Coast Guard is diving into wind power, too. The new turbine has been installed at the Coast Guard’s Southwest Harbor Base in Maine.

The new turbine is only rated at 2.4 kilowatts, but in this case, size doesn’t matter. What really matters is that the U.S. military has historically been very cautious about adopting wind power partly due to concerns over radio interference, but now with two branches of the armed services getting their feet wet, perhaps a tipping point is near and more clean, renewable wind power is in store across the Department of Defense.

Scientists from Saint Louis University in Missouri are reporting the development of a new class of biobased fuel cells, which could replace disposable batteries and their toxic components. The new biofuel cells could be used to power small electronic devices such as laptops and cell phones, and could be charged by sugar from common sources such as soda pop and vegetable oil.

Conventional batteries, even when rechargeable, have become an enormous logistical issue, not only for consumers but also in terms of providing portable power for military purposes and dealing with supply and disposal issues, especially at remote bases. The U.S. military has already begun to develop biobased fuel cells, so chances are that the consumer market won’t be far behind.
