    You got me to thinking about why I have had these experiences. In the oil
    business, drilling rigs drill 24 hours per day, 7 days per week. If one has
    trouble, or if a decision needs to be made, we are required to work until we
    solve the problem or make up our minds (empty as they are sometimes). I have
    had occasions where I went into work at 6 in the morning only to get home the
    next day. It is rare, but it has happened. More likely is the case where I go
    in at 6 and leave at midnight. That happened this year a coupole of times. Now,
    a drill rig in the deep water costs up to $300,000 per day. Why does it cost
    that much? Part of it is due to the energy required to 1) make the steel, 2)
    weld it together, 3) run supplies to it 150-200 miles from shore etc. The
    portion of the day rate that we pay for the rig alone (approx $200,000 a day)
    is repayment for the energy already used in its manufacture. The rest is
    supplies, food etc. (for details see )

    I tell you this to pose the question, is it more energy efficient for me to go
    home at quitting time letting at least 16 hours go by while the rig bobs around
    in the water, using fuel to remain on station but idle, or is it more energy
    efficient for me to take my car to work alone. Here is the math. The drill ship
    uses 12 tons of fuel a day to stand still. If I make the ship wait 16 hours,
    then I have spent about 8 tons of fuel so I can drive in a carpool and save a
    gallon. I don't know how much a gallon of gas weighs but figure it like this. A
    gallon of water weighs 8 pounds so say that gas weighs 6. If I make the rig
    wait only once a year for 16 hours, I have spent 12,000 pounds of fuel. At 25
    mpg, I could go 50000 miles in my personal car before I make up for that
    deficit. Since I only drive around 12,000 miles per year, it is more efficient
    for me to drive than to make a rig wait, ever. This calculation doesn't count
    the energy payback for building the rig in the first place. Car pools are not
    always the most energy efficient situations for some professions.
