    I don't know who you've been listening to, but I would strongly suggest that you stop

    Regardless of the hyped oil reserves numbers, the U.S. cannot produce enough domestic crude to supply itself independent of imports. This is common knowledge to anyone who has done a modicum of research into the issue (Hannity, Beck, and Limbaugh do not count as research -- to the contrary, in fact).

    As to diesel, it burns dirtier than gasoline (particularly with particulate emissions), and biodiesel has less energy content than regular diesel, although thermodynamically diesel is a more efficient internal combustion fuel than gasoline. Again, common knowledge . . . . .

    FAME [Fatty-Acid Methyl Ester, perhaps more widely known as biodiesel] has a lower energy content than diesel due to its oxygen content, and as a result, performance and fuel consumption can be affected. It also can have higher levels of NOx emissions, possibly even exceeding the legal limit. [...] The loss in power when using pure biodiesel is 5 to 7%.[29]

    I kinda like the concept of NG/CNG cars, but -- it will only take a few news videos of them blowing up during crashes to make the public run far, far away from them.

    Propane tanks -- unsafe at any speed (apologies to Ralph Nader )

    I'm not sure it's an efficient way to go, it's fine in cities to lower pollution. But otherwise, not sure it the best approach.

    The morality of abortion is not a religious belief, any more than the morality of slavery, apartheid, rape, larceny, murder or arson is a religious belief. These are norms of the natural law of mankind and can be legislated even in a completely religionless society.

    Batteries in cars catch on fire and present electrocution risk to people in crashes and first responders. Every technology has it's inherent risk.

    Except in the most odd and extreme of situations, no they don't. Try sourcing your claims instead of making them up.

    Will this do?

    The large, high-voltage batteries used in plug-in vehicles can be more easily damaged in a crash than traditional car batteries and create more potential to electrically shock occupants and rescuers. The Volt’s 400-pound, T-shaped battery extends under the middle of the car and between the back seats rather than fitting under the hood with the engine of a gas-powered vehicle.


    “Based on the available data, N.H.T.S.A. does not believe the Volt or other electric vehicles are at a greater risk of fire than gasoline-powered vehicles,” the agency said in a statement. “In fact, all vehicles — both electric and gasoline-powered — have some risk of fire in the event of a serious crash.”

    About what? That CNG and propane are two different things?

    Mostly, I like the idea because natural gas is plentiful in the US, and doesn't put us at the mercy of the Iranians in the Strait of Hormuz.

    To be honest, I don't think it's a good idea to have most of our transportation energy coming from one particular commodity. Diversifying the fuel sources we use means that oil prices don't have as much potential to be a drag on the economy. I don't think we want to move our whole transportation system over to CNG, but it's certainly good to have options.
