...Since you can't buy most consumer electronics from a US source anymore, one option is to limit purchases. Buy a good VCR/DVD from an electronics store and keep it for a few years. Get a DVR or a DVD burner and stop buying those huge plastic VHS tapes. Repair your TV instead of replacing it.
With the holidays season coming up, the strong urge is to shop. The trend is even stronger when you have kids to shop for. Think about rental services like Netflix instead of buying game packages that will have a useful life of about a month. Then there's the more creative option.
If you have the money or interest, you could buy your child a solar or wind power system. You can call it a "freedom tree" if you have to explain it to your Republican friends. Get a small system to power their room. As a techie, I would have loved such a toy.
If your kid is not so inclined, you can look into the financial benefits. Take your energy savings, take some for paying off the freedom tree and make the rest an allowance. If the savings are really high, make it a college fund too. It is a lot sounder investment than PetroChina.
