  • You're very deceptive in talking in terms of dollars the whole way until page 62 before I even knew what you're paying per kWh, then realize that you're paying $0.32/kWh when the national average is around $0.10/kWh, then I find that your utility, PG&E employs tiered rate system and you're reporting reporting the unit cost at highest tier rate.

  • This is perhaps the most widely viewed presentation I have ever done. It is posted multiple times on SlideShare and has been widely distributed.

    I was visiting a company recently and in the middle of the meeting the CEO stopped and said, 'Oh my, I didn't realize who you were. You did that presentation on light bulbs.'

    Four yeas to write a book, and I became famous for a PowerPoint on light bulbs...

    My wife thought I was a bit crazy photographing all our light fixtures and then testing 11 brands of CFLs. But she has come around and posted links to the most useful products we have used at www.EltonSherwin.com
