Here is an interesting factoid that I picked up visiting Craig Vogel?? LiveWell Collaborative design and innovation program at the University of Cincinnati a few weeks back.
According to Procter and Gamble, if every household in the US switched to Tide Cold Water, and didn?? use hot water to wash clothes, the results would be:
1) a 3% decline in total US energy consumption;
2) a $67 annual saving for each US household in energy costs;
3) 8% of the total US pledge to reduce CO2 in the Kyoto Protocol (which it didn?? sign) would be met.
This is from one product doing one thing. Maybe it wouldn?? be so hard to reduce CO2 emissions, if we really tried.
