Fastest Computer in the World Focused on Climate Change

jaguar-xt5
The Jaguar XT5 computer, housed at the Oak Ridge National Laboratory in Knoxville, Tenn. and owned by the Department of Energy was just named the fastest computer in the world by the TOP500 list.  It has a performance speed of 1.759 petaflops or quadrillions of calculations per second and that power is being focused on solving the issues of climate change.

The Jaguar is an open science machine for performing peer-reviewed research.  It is being used to create models and simulations for predicting regional climate change, studying enzymes for developing better ethanol and writing algorithms for fast nuclear reactors that would produce less waste.  A billion hours of processor time have been scheduled for 2010 by users like the National Oceanic and Atmospheric Administration, the Argonne National Laboratory and the National Science Foundation.

If you're thinking that the fastest computer in the world should be used for other problems too, don't worry, the Jaguar along with the other supercomputers on the list are also being used for things like nuclear security, developing better medicines and examining the origins of the universe, among other things.

Oak Ridge hosts four of the supercomputers on the list, including Kraken which was number three in the world with a speed of 831 teraflops.  Where the human brain's processing performance ends, these supercomputers pick up, allowing tons of information to be sorted, processed and analyzed.  With all of the challenges facing us in tackling climate change, it's nice to have them on our side.

Solar Powered E-Reader Makes E-Books Eco-Friendlier

solar-ebook
A recent study by the Cleantech Group revealed the much lower envrionmental impact of e-readers - specifically the Kindle - compared to traditional publishing, but the devices still require charging from the grid.  LG's new e-reader takes care of that:  it's outfitted with its own integrated solar panel, allowing it to run on clean, renewable, solar power.

The thin-film panel is 10 cm wide and just .7mm thick, adding only 20 grams to the product.  The panel is 9.6 percent efficient and needs 4.5 hours of sunlight to juice the device for an entire day. 

Last year, LG introduced a display that can be illuminated by sunlight instead of the backlight when used outdoors, increasing visibility and cutting energy use by 75 percent.  Press for the new e-reader doesn't indicate what kind of display it uses, but this product would be even more impressive if it included the sunlight-illuminated one.  That way you could read easily outdoors while charging the device at the same time.

Tech Companies Top Newsweek Green List

newsweek-green-rank
Tech companies dominated the top of Newsweek's "Green Rankings," with Hewlett Packard taking the number one spot.  The list ranked the 500 largest corporations in America based on their environmental impact, green policies and their social responisibility reputation.

Tech companies made up four out of the top five spots:  HP at No.1, Dell at No. 2, Intel at No. 4 and IBM at No. 5.  Google was farther down the list at No. 79 and Apple even lower at No. 133.  The criteria went beyond the environmental-friendliness of their products, factoring in things like the companies' greenhouse gas emissions, water use, waste disposal, environmental initiatives, pollution policies and even how they were viewed by consumers.  You can see specifics on the methodology here.

HP was named the greenest company mainly because of their commitment to reduce GHG emissions and to remove toxic materials from their products.  Greenpeace made a big splash a couple of months ago by calling the company out on their failure to keep their promise on eliminating hazardous materials, but I guess for this ranking, intentions counted as much as action.

HP has made some strong commitments to reducing GHG emissions though. They just announced that they would cut their emissions to 40 percent below 2005 levels by 2011.

 

California to Get Large Renewable Energy Standard, One Way or Another

cali-renewable
Last Friday, the California legislature approved a new renewable energy standard for the state requiring 33 percent of its electricity to come from renewable sources by 2020, but Governor Schwarzenegger has vowed to veto it.

The good news is that it's not the size of the clean energy standard that the governor has an issue with, it's the part of the bill that requires two-thirds of that energy to be generated in-state.  Schwarzenegger plans to issue an executive order that also calls for a portfolio of 33 percent renewble energy by 2020, but puts no limit on the amount of clean energy the state can import.  It's possible that he will also expand the definition of "clean energy" to include nuclear and hydroelectric power.

One downside of this portfolio standard coming as an executive order is that it may no longer be binding when Schwarzenegger leaves office in 2010.  He's supposed to issue the order by the end of the week.

Either way, California will end up with the largest renewable energy standard in the country.  The state is already requiring its largest utilities to get 20 percent of their electricity from renewable sources by 2010 - a goal none of them are likely to meet.  One of those utilities, San Diego Gas & Electric, only got 6.1 percent of it electricity from clean sources last year.

Colleges Look to Cut Down on Paper with Kindle

kindle-u
Six colleges and universities are participating in a pilot program using the Kindle for accessing textbooks.  Princeton University, the University of Virginia, Case Western Reserve University, Reed College, Pace University and Arizona State University are all testing the technology in select courses this fall.

In May, Amazon announced its launch of a new version of the Kindle (the Kindle DX) with a larger screen designed for textbook and periodical reading and a better web browser.  This pilot program is putting the new e-reader directly in the hands of its intended market.

The colleges are hoping the pilot program will lead to another way for them to increase their sustainability by reducing their use of printed paper.  Textbooks and other course materials will be made available online for the classes and students selected to use the Kindles.

This idea is great, but mainly because textbooks and course materials should be available electronically at all schools for all classes, whether they're accessed by a Kindle, a laptop or on a computer at the library.  It seems like that conversion is long overdue for textbook makers and universities.  The universities participating are ones that have a bit of influence, so let's hope that if they adopt electronic course materials, others will quickly join them.
