The article commences by describing the fact that average US household uses 150 pounds of CO2 every day. Europe uses about half (I think it is useless comparing to other countries since developing countries have much different standards of living and climates). The objective of this couple is to bring down its consumption to 30 pounds a day in just one month.
Needless to say it was not possible (I said needless because I did not expect them to be able to do it. People can't just cut down commutes one day to another, or magically install efective and cheap solar panels in their roofs). After installing new lightbulbs, hiring an "environmental consultant" to help them learn about things like isolating the house so it is less afected by weather, they cut their emissions to about 70 pounds of CO2 a day. That is a lot.
It seems the approach is not about saving energy. We have grown used to a way of life that depends on energy. Polluting is not a choice, is a byproduct of current standards of living. Wasting, or not, is a choice. I can decide to leave n products in standby or not. To walk two blocks of to drive. To use energy saving lightbulbs or the ones that came with the apartment. To.. ok, I think I made my point.
pd. The couple in the article sent its average back to 15o pounds a day because they needed to fly to Oregon (from Virginia). I did not see that coming.
