The building developers and Adrian Smith + Gordon Gill Architecture deserve to be applauded for this.
Via FastCompany:
The tallest building in the U.S. is about to get a $350 million green makeover as part of a plan to cut electricity use by 80% and save 24 million gallons of water each year. The goal of the project, according to developers, is to turn the Sears Tower into a living laboratory for green retrofits.

Governor Palin | Doesn’t Finish the Job
Palin resigns her post. One can speculate that the state of Alaska will be in better hands when Lt. Gov. Sean Parnell takes over the responsibilities that Palin is abandoning.
Yet, if Palin truly is leaving in order to prepare herself for a 2012 Presidential run, what does it say about her character as a leader? We can surmise that she places her ambitions ahead of following through on a job she was elected to do.
Unless there are family matters she is attending to, which is not something she has stated, or she's too strained from her endeavours, leaving an elected office 17 months early of her term's expiration in December of 2010, while saying she's "doing what’s best for Alaska," means Palin is effectively giving herself a vote of no confidence.
