5/17    Which  one is more energy efficient?
        1. Hybrid vehicle
        2. Burn the same amount of oil at a power plant and use the electricity
           to power an electric-only vehicle.
        Thanks.
        \_ hybrid.  electrical generator are not very efficient unless you
           do it on a massive scale.  then, electricity can't be stored.
           you would be better off with some sort of hybrid.
        \_ I don't know, but I'll guess the Hybrid.  The power plant would
           probably have the edge in just plain kilowats/gallon, but car
           batteries have a pretty big creation cost.  The energy of
           making the batteries is pretty large.  Again, I don't really
           know though.
           \_ not to mention how much power is lost in the battery
              charge/discharge cycle.
        \_ We don't usually burn oil at power plants.  We use coal.
           \_ Yeah, but there are power plants that run on oil.
                \_ Like Hawaii
                   \_ Is it coconut oil, or tanning oil?
                      \_ Oriental massage oil.
                   \_ But here in CA we only burn natural gas.
           \_ coal, gas, hydro, nukular, etc.. --  the beauty of the electrical
              distribution system is the generation sources are diverse as well.
              No reliance on one increasingly rare resource.
              \_ Yes, we should be using nuclear.
                 \_ And the newest round echo-chambering begins...
