How do you propose that we boycott the oil companies? Everything we use on a day-to-day basis is shipped using petroleum. You can buy/eat locally grown produce, but even then it's been transported with petroleum, although less of it.

There are two ways to reduce price. Lowering demand or increasing supply. Increasing supply by opening Anwar (sp?) and exploring other fields (maybe antarctica, etc.) can reduce costs. There's also developing alternative fuel sources which will also reduce the demand for petroleum. Probably the dirtiest, yet most abundant source of fuel we have is coal. We can turn it into petroleum, but dealing with coal (especially the high sulfur kind of my area) is dirty business for the environment. However, we may not have much choice.
