I stumbled on a great site 'The Green Guide' owned and run by 'The National Geographic Society'
It covers many Green Topics including, Carbon Neutral Products, Green Issues (Of Course) Green Travel, Green Living and much more.
Their website is http://www.thegreenguide.com/
Don't forget to visit the homebrewpower Forum, it's free, it covers tons of subjects about Carbon Neutral Power Generation (Wind Turbines, Solar, CHP, MCHP, WVO & WMO Burners & many other interesting topic's)
It is brand new, free to join and specifically for like minded people.
