Having discovered that building demolition, construction and maintenance uses twice as much energy as transportation, I am promoting the use of super-insulation. Specifically the use of straw bales in building construction. At the 2007 Solar Decathlon in DC, U of Penn students said that straw bale insulation was 10 TIMES more cost effective than any other insulation analyzed. My dream is to see 100,000,000 SB buildings constructed worldwide in the next 10 years, especially China, India, Pakistan, etc. See my think piece at: http://www.ecobusinesslinks.com/straw_bale/straw_bale_solar_sustainable_development.htm Also my blog: gleeaikin.blogspot.com
