In the case of items I have decided to own I work towards the least energy use I can, I use a pre-owned laptop instead of a desktop computer, when I've owned and operated an automobile I have only owned used models that achieve good levels of efficiency (though I strive to do without whenever possible), I address efficiency in the houses I live in. Energy efficiency is the lowest of low hanging fruit.
As Amory Lovins has said " We've found a Saudi Arabia under Detroit." By implementing lightweight materials in autos we can save "8.5 million barrels of oil a day...and it's a whole lot easier to find that oil than under 10,000 feet of water". Here Mr. Lovins is referring to the much touted "new" technology of drilling in deep water. The light materials he is referring to are available now.
As reported by Joe Romm over at Climate Progress "The energy efficiency provisions in the House energy and climate bill (H.R. 2454) could save $750 per household by 2020 and $3,900 per household by 2030, according to an analysis by the American Council for an Energy-Efficient Economy (ACEEE). "
Not only do these provisions pick the lowest hanging fruit in the battle against needless consumption which causes climate change but they also create jobs, "An ACEEE news release notes that not only will efficiency reduce the costs to consumers and businesses of cutting carbon pollution:
ACEEE estimates that approximately 250,000 jobs will be created by the energy efficiency provisions in H.R. 2454 by 2020, with a total of 650,000 jobs generated by 2030."
It is just common sense, why pay for something you are just wasting?
