    Default alternative fuels/australia talks back

    Hi, just listened to an hour on this subject. Might be of interest to people who have a podcast facility.
    Basically, what Andrew says is confirmed. but there seems to be some new technology of producing ethanol.
    California seems to be a very high user of ethanol but now they are thinking of putting a stop to it as it requires mor energy to produce than it is worth?
    Sounds like biodiesel or a combination of biodiesel and LPG is a good option but nobody is considering it.
    Natural gas seem a goer.
    The bottom line is that we have to find an alternative if we want to keep our mobility.

    Compared to oil, the EROEI (energy return on energy invested) numbers for alternative energy sources tend to be pretty shabby. Most aren't a net loss, but they just aren't as energy-packed as fossil fuels are. Take a look here and compare the non-renewable vs. renewable numbers.

    Mainly to do with the fact that oil is, indirectly, a stored form of several thousand years' worth of solar energy (it was needed to grow plants that fed growing dinosaurs -- or fed what the dinosaurs ate), and all that's needed to get that energy back is to punch a hole in the ground and perform a fairly simple refining process.
