About the Coaches

Chad Lipton is program manager for the Energy Initiative at National Geographic. He most recently worked for Elysian Energy as an energy auditor, carrying out site visits and analysis in the residential energy field. Prior to Elysian Energy, Chad worked in the field of carbon management, where he performed site verification for greenhouse gas emission reduction projects. From 2004-07, Chad worked as an environmental health specialist in Africa carrying out water and sanitation projects in Côte d’Ivoire and Mozambique, where he strengthened his ability to communicate in French, Italian and Portuguese. Chad has master’s degrees in Environmental Health Science and International Relations from The Johns Hopkins University.

Tom Sahagian is the director of the Energy Division at Power Concepts, a consulting engineering firm based in New York City. He is most comfortable when he is in the depths of a boiler room or at the front of a classroom, and has spent much of the last 30 years in one or the other. Mr. Sahagian has worked extensively with a broad range of residential, commercial and industrial energy-efficiency technologies. Most recently, he served on NYC Mayor Michael Bloomberg’s Green Codes Task Force. Mr. Sahagian teaches frequently and speaks widely on the topics of energy and water conservation.

Dave Chameides, aka “Sustainable Dave,” is a two-time Emmy Award-winning cameraman and TV director (ER, Third Watch, Studio 60) who decided to stop taking out the trash (and the recycling too!) for an entire year. Instead of throwing it away (wherever that was) he’d start keeping it all in his basement and see what happened. And as if that wasn’t enough, Chameides decided that he would list all the waste he created on his site 365 Days of Trash in order to share what he was learning. Chameides began talking to school groups, religious institutions, and businesses about what people could do in their own lives. He has created a seminar for schools, Chasing Sustainability, that has been heard by groups as small as 10 and as large as 2,000, and the feedback from students and teachers alike continues to be overwhelming. Today, Chameides continues to lecture to schools all over the country and speak about how everyday people can do a tremendous amount to lessen their footprint without living in a cave. He writes a weekly column for the site Care2, and is on the board of advisors for Carbon Salon, a site devoted to helping people track and decrease their fossil fuel use.

    Wow — the other coaches are all better-looking and more accomplished than I am — how did I end up in their company?

    It looks like we had pictures taken on good hair days. The others may have more recognized accomplishments, but your knowledge as a boiler room savant should not be understated.

    Good day coaches

    I must commend you guys for the work you are doing.
    It is the sort of thinking we need today in our society.

    I would like to see more people in my country become more aware of their output, but I suppose I have to be the change!

    Kind regards

    I´m 100 % with what you do and I´m considering joining the challenge.
    On the other hand after my yearly visits to the US i have a thougt. Why no run the challenge with corporations, hotels schools clubs.Just some examples.
    Coporations :Car rentals do they need to keep shuttle buses running the engine when empty?
    Hotels:Freezing airconditioning when the room is empty or in the lobby.
    Schools and clubs: Baseball pitches or courts floodlight all night when nobody is palying?
    Airports: Miami Airport is freezing cold at night a couple of degress warmer how much can you save.?
    How many houselds doing the challenge would one of these institutions equivalate to.
    With best regards and thanks
