Solar Cell Makers, Consider Another (Potentially) Renewable Resource: Water
PV manufacturing typically consumes large quantities of water. With solar cell manufacturing facilities moving into water-scarce regions, like the Middle East, PV fab processes must be retooled to conserve and recycle water. Here’s how.

Green Jobs Are Real: German and American Solar Industry Both Employ More People Than U.S. Steel Production
With roughly 93,500 direct and indirect jobs, the American solar industry now employs about 9,200 more workers than the U.S. steel production sector, according to 2010 Bureau of Labor Statistics. The American steel industry has historically been a symbol of the country’s industrial might and economic prosperity. But today, the solar industry has the potential to overtake that image as we build a new, clean-energy economy.

Images of Desertification in Inner Mongolia, China (Pics)
via internet science tech

The Guardian has a great slideshow illustrating the desertification of Mongolia.

“Inner Mongolia, China’s third largest province, is battling severe desertification. Over-grazing, logging, expanding farms and population pressure, as well as droughts, have turned once fertile grasslands into sandy plains. As part of China’s efforts to stop the land degradation, NGOs have been helping with reforestation”

Desertification is a major issue in China, where usable land is lost on an annual basis. If you’re feeling un… Read the full story on TreeHugger

Why Geoengineering Should Not Be Dismissed Entirely
via internet science tech

Geoengineering—or the concept of trying to artificially alter the Earth’s climate to combat climate change—has always been a contentious topic. Matthew has already made the case for why not all forms of geoengineering are created equal, and gave a cautious welcome to a UN moratorium on geoengineering. Now James Murray over at Business Green has a witty piece on the inevitable in-fighting an… Read the full story on TreeHugger

A Medium Solar Flare

A Medium Solar Flare
The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class (minor) radiation storm and a spectacular coronal mass ejection on June 7, 2011. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface. A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up a sixth of the total energy output of the Sun each second. Solar flares strongly influence the local space weather in the vicinity of the Earth. They can produce streams of highly energetic particles in the solar wind, known as a solar proton event, or coronal mass ejection. These particles can impact the Earth’s magnetosphere and cause a geomagnetic storm. A geomagnetic storm is a temporary disturbance of the Earth’s magnetosphere caused by a disturbance in the interplanetary medium. A geomagnetic storm is a major component of space weather and provides the input for many other components of space weather, and present radiation hazards to spacecraft, astronauts and cosmonauts. The current flare event is moving at 1400 km/s according to NASA models. The flare event should deliver a glancing blow to Earth’s magnetic field during the late hours of June 8th or June 9th. High-latitude sky watchers should be alert for auroras when the it arrives.

This guest post was written by Andrea Thomas, Walmart senior vice president of sustainability.

Eating healthier is something everyone wants to do, but few of us have figured out how to do it. At Walmart, our customers have told us they are overwhelmed with choices in the grocery store and don’t have time to research product marketing claims. Likew… Read the full story on TreeHugger

Farmers’ Protection of Nature Worth Billions a Year

I wrote yesterday that focusing on food miles risks oversimplifying the idea of local food. The fact is that how are farms are run, and by whom, is at least as important as where they are located. David Suzuki has already made the case that <a href="… Read the full story on TreeHugger

Kaid Benfield on The Greenest Building Is The One In The Right Context

Kaid Benfield of the NRDC was in Wilmington for the Greening Historic Communities Symposium to speak about how The greenest (historic) building is the one that’s in the right context. He writes:

If you care about green preservation, you also have to take into account that households in centrally located properties and neighborhoods use far less energy and emit far… Read the full story on TreeHugger

Is the London Olympic Basketball Venue The Ugliest Building Ever?

I was shocked and appalled at Bonnie’s post on the London Olympic basketball stadium; it gives flatpack a bad name. It looks the the shrink-wrapped boats you see at marinas in winter. It looks like a giant bunion pad. Now I know this is not a money-no-object extravaganza like Beijing was, but British architects have done great temporary designs, from Archigram in the sixties to Mark Fisher and Jonathan Park with their rock sets for… Read the full story on TreeHugger
