Here are a few tips to help reduce your carbon footprint:

  • If you are going to drink wine anyway, consider drinking one of Far Niente's varietals. They've installed a 400kW solar PV system (PDF of SF Chronicle article) that results in a net-zero energy bill and offsets a large percentage of their CO2 emissions
  • When flying, which we know is one of the worst activities from a carbon standpoint, you can at least connect through Denver International, which just dedicated a 2MW solar system (PDF of Sharp Energy press release).

In his call to action two weeks ago, Al Gore compared the future development of solar electricity sources to the development of the semiconductor industry. His implication was that Moore's Law, which reliably predicted that the price/performance of semiconductors doubled every 18 months, would also apply to photovoltaics.

ComputerWorld, in an article two weeks ago, assesses this comparison as flawed. (As did Harry Gray of Cal Tech, as I reported earlier today.)
