One year after BP's Deepwater Horizon disaster in the Gulf of Mexico, a hydraulic fracturing operation in northern Pennsylvania experiences a blowout resulting in the release of fracking liquids. The use and chemical content of fracking liquids is a point of contention when debating what role natural gas will play in the future of energy.

Now read carefully: Almost all the clean up workers who worked on the Exxon Valdez spill are dead. (previously)

Dirty Coal, Clean Future
To environmentalists, "clean coal" is an insulting oxymoron. But for now, the only way to meet the world's energy needs, and to arrest climate change before it produces irreversible cataclysm, is to use coal—dirty, sooty, toxic coal—in more-sustainable ways. The good news is that new technologies are making this possible. China is now the leader in this area, the Google and Intel of the energy world. If we are serious about global warming, America needs to work with China to build a greener future on a foundation of coal. Otherwise, the clean-energy revolution will leave us behind, with grave costs for the world's climate and our economy. (more here and responses here, here and here)

The world's largest solar power plant will probably be cleared for construction in California. At 1GW it is the size of a nuclear power plant and nearly doubles the US installed base of commercial-scale solar power. It will take 6-years, $6-billion and 7,000-acres. Proposed site (on Google maps). It will use parabolic trough's (video). It is being built by a German company (construction video / operation animation). There are many other CSP (Concentrated Solar Power) projects.

The fire is out on the offshore oil rig Deepwater Horizon.

"An early suggestion that damage would be minimal because the fire was consuming most of the fuel 'does have the potential to change,' BP official David Rainey told the New York Times." [more inside]

Recently, John Michael Greer has been exploring a little known idea of the deceased economist E.F. Schumacher (a student of the oft-discussed Keynes). "Schumacher drew a hard distinction between primary goods and secondary goods. The latter of these includes everything dealt with by conventional economics: the goods and services produced by human labor and exchanged among human beings. The former includes all those things necessary for human life and economic activity that are produced not by human beings, but by nature. Schumacher pointed out that primary goods, as the phrase implies, need to come first in any economic analysis because they supply the preconditions for the production of secondary goods. Renewable resources, he proposed, form the equivalent of income in the primary economy, while nonrenewable resources are the equivalent of capital; to insist that an economic system is sound when it is burning through nonrenewable resources at a rate that will lead to rapid depletion is thus as silly as claiming that a business is breaking even if it’s covering up huge losses by drawing down its bank accounts."

Rethinking Earthrise. On the 40th anniversary of the NASA's Apollo 8 mission [caution: weird JFK animation], which answered Stewart Brand's epochal, LSD-inspired question "Why haven't we seen a photograph of the whole Earth yet?" with an unforgettable image of a seemingly fragile and isolated blue planet, Nature editor Oliver Morton -- author of a new book on photosynthesis called Eating the Sun -- disputes the notion that the Earth is fragile and isolated. "The fragility is an illusion," he writes. "The planet Earth is a remarkably robust thing, and this strength flows from its ancient and intimate connection to the cosmos beyond. To see the photo this way does not undermine its environmental relevance -- but it does recast it."

Wal-Mart's environmental record is less than perfect, of course, but if they managed to pull this off it would be hard to see it as a bad thing.

Global warming underestimated by up to 78%. Scientists analyzing historical climate data for Europe have established the existence of a greater-than-anticipated positive feedback mechanism between high temperatures and global carbon dioxide levels. This provides more scientific evidence to support previously-expressed concerns that as global warming intensifies, a chain-reaction of considerably higher temperatures may occur. This corresponds with a new report released by the Australian government, claiming that "there is now perceived to be a greater risk that the upper end of the well known IPCC TAR estimate of a 1.4 to 5.8°C temperature rise will be reached or exceeded by 2100." "Estimates of future warming . . . may have to be raised by about 50 percent."

Unexpected Downside of Wind Power - Wired reports on the shutdown of wind power turbines along Altamont Pass in California. Wind power is seen by some as an alternative to burning fossil fuels; yet these turbines are being shut down over environmental and ecological concerns. Some of the concerns about turbines are that they endanger bird migrations, yet others say that they are not a problem for bird migrations. It's not just a question of the ecological footprint, though. The entire environmental impact has to be assessed for any project. Hydroelectricity is not without its effect on ecosystems, either (Scroll down to "Ecosystems and Large Dams", about 40% of the way down).

If even green or renewable energy sources cannot be accessed without a significant adverse environmental impact, how can we meet our energy needs? Reducing consumption is only approaching the problem from one side. How do you properly gauge the environmental impact of a project and when is it okay to give it the green light? Or are we being oversensitive and should we let natural selection handle the birds that can't adapt?

A kilometre-high solar tower, to be built in the Australian outback by EnviroMission Ltd, will become the world's tallest structure when completed in 2006. Designed by Jorg Schlaich of Schlaich Bergermann und Partner, the solar tower (or solar chimney) operates like a hydroelectric power plant, but uses hot air instead of water, and it could provide enough electricity for 200,000 homes. Time calls it one of the best inventions of 2002, and I think it's one of the most ingenious ideas I've ever heard. Another solar chimney project was planned in Rajasthan, India, but I haven't found any information on its current status.

As the Alberta government ratchets up its campaign against the Kyoto Protocol (and the Canadian government's support thereof), two environmental groups release a report that argues that Canadians could cut greenhouse gas emissions by 50 per cent and save $30 billion a year in the process by 2030 (PDFs of the report summary and full report). And, if reducing emissions starts at home, you can apparently cut your own energy bills and emissions in half simply by stopping leaks and drafts in your house.
