Learn a little bit about energy consumption, and take a pledge to do your part and reduce your energy consumption at the Six Degrees of Energy Efficiency web site.

It's interesting though, that this organization - which is largely funded by the many companies that are its "partners" - promote saving energy through products substitution. You can reduce your energy use, if you buy a new product that uses less energy - preferably one of the products made by one of the partner companies. This web site deals with home/residential energy consumption so the fact that increased industrial energy used to create these new products that use less energy is not part of the equation. But then, Americans are inveterate consumers, so I suppose promoting the consumption of energy saving products is better than nothing.
