Al Gore and T. Boone Pickens are just two of the most prominent people calling for us to get off our oil addiction. But how will it hit our wallets to do that? These sites give some guidance.

Grid parity. The stock market watch site Seeking Alpha watches the energy sector, among many segments of the economy, and posts opinion and analysis from blogs and other sources around the Web. This entry from earlier in the year talks about "grid parity," a term now bandied as the point when alternative energy sources are as cheap - or expensive - as traditional sources. The article notes that such parity depends on many factors, but is inevitable.

Clean edge. A report from "clean-tech" research firm Clean Edge says solar power will reach cost parity with fossil-fuel sources by around 2015. The report offers a plan for the United States to get 10 percent of its power from solar by 2025.

Leonard's world. At, Andrew Leonard writes "How the World Works," a blog about globalization. This June installment says solar power is "just about ready for prime time," based in part on the soaring production of photovoltaic cells - the building blocks of solar panels.

Pickin' on Pickens. The libertarian Cato Institute posts a critical essay on oilman Pickens' call for big subsidies on wind energy. "If wind energy were a sensible economic investment, it would not need the lavish federal and state subsidies already in place or the additional largesse sought after by Mr. Pickens," it observes.

This is the site all about the "Pickens Plan." Pickens presented his plan to a U.S. Senate panel last week.

Al Gore. And we shouldn't leave out the all-things-Gore site, where you even can buy signed copies of photographs by his wife, Tipper.
