An argument for the Green power of..*gasp*..Capitalism?

Yes, you read that right.
Capitalism. It's often a dirty word in the green scene. I'll spare the editorial or spouting of my (still-evolving) beliefs. Instead I would just like to cite an article that confirms something I had been observing. As the price of gas soars, as yet unhindered by government action, it is actually making 'green' goods more affordable (our Toyota Prius is no longer just a cool ride - it's an economical choice!).

Here is a summary of a Wall Street Journal article I read on WSJ.com:

With soaring energy prices pushing up the price of mainstream goods, green products are becoming just as-or even more-affordable than ever. The reason is that green products, by their very nature, have less fossil-fuel content than competing non-green brands. Their manufacturer also tends to consumer less oil, since green entrepreneurs favor renewable-energy and energy-saving practices. For example, Eco-Products, a company that makes compostable dinnerware, expects sales to jump this year to an estimated $50 million from about $11 million last year. Its products are made from a corn derivative rather than petroleum, which is standard in the industry. As a result, Eco-Products has been able to hold its prices steady while its competitors prices are going up. Similarly, TerraCycle, a maker of fertilizer from worm castings, plans to market an article fire log this winter that has a soy wax as a key component. Its biggest competitor makes a petroleum-based version.
