Notes
  • In April of 2011, I was invited to a dinner party at a swank Pacific Heights home where California’s Lt. Governor, Gavin Newsom, was speaking.

    Newsom is a larger than life character. I had never met him before, but like Bill Clinton, he dominates a room when he enters it. Like Clinton, he demonstrates a tremendous grasp of the facts. And, like Clinton, his personal life has had very public problems. I should probably stop there.

    At dinner I was seated next to Peter Darbee, then CEO of PG&E. He seemed distracted. At one point in the conversation, as we discussed energy efficiency, he said to me, “How much have you reduced your PG&E bill?”

    Thereafter, our conversation floundered. Perhaps I should have said, “Peter, how much have you reduced your bill?” The following week he resigned–a casualty of PG&E’s San Bruno gas explosion.

    But his question stayed with me. Was I one of those advice-givers unable to succeed in the real world? So, when the cities of Atherton and Portola Valley asked me to come speak about energy efficiency in large homes, I decided it was time to audit my home again.

    Thanks to Peter Darbee’s unsettling question, here are the results of the latest audit of the Sherwin Household’s conservation measures:
