Snippets – Zero Net Energy

The International Living Future Institute (ILFI), owner of the Living Building Challenge, is going where no certification program has gone before with a new Net Zero Energy Building Certification program (BuildingGreen.com).  You can read the International Living Future Institute press release on the NZE Building Certification program here There is a zero net energy gas station in Beaverton, Oregon (OregonLive.com).  KB Home, one of the largest homebuilders in the U.S., has developed ZeroHouse 2.0, a house designed to achieve net-zero energy. The home is currently available in Tampa, Florida, and in San Antonio and Austin, Texas, but the company plans to expand the availability of net-zero options to other cities throughout 2012 (BuildingGreen.com).

24/7 Wall St. evaluated a couple recent studies (from Ceres and the NRDC) and also conducted some of its own analysis, focusing on the 30 largest American cities,  to  come up with the following list of 10 large American cities at the greatest risk of running out of water:

10. Orlando, FL

9. Atlanta, GA

8. Tucson, AZ

7. Las Vegas, NV

6. Fort Worth, TX

5. San Francisco Bay Area, CA

4. San Antonio, TX

3. Phoenix, AZ

2. Houston, TX

1. Los Angeles, CA

You can read more about their analysis and reasons for inclusion of each city here.

A note from Anna – I do not know much about 24/7 Wall St. or their track record on this sort of analysis. I think this sort of list is good for raising awareness that it is not just cities in the dry Southwest that are facing future water shortages. However, there are a few items in this article that gave me pause – first is the consistent misspelling of San Francisco as “San Fransisco”, second is the consistent listing of the NRDC (Natural Resources Defense Council) as the “National Resources Defense Council.”
