12 thoughts on “Magical Thinking”

  1. I had that discussion with a guy talking about his “zero emission” car. I pointed out that while the car may be zero-emission, the electricity comes from somewhere (mostly gas and some coal where I live). The thing I don’t know is, what is the difference in CO2, etc., emissions needed to charge an electric car compared to a gas powered car getting 30 mpg?

    Zero Emission is such a lie.  I wonder how they get away with it.

    Assuming the electricity is generated by burning a fuel, you can compare an electric vehicle with a gasoline-powered one by noting that the efficiency of an electric generating station, including transmission and conversion losses is about the same as a gasoline engine. Therefore, the same car will use about the same amount of fuel whether the fuel is burned at the power station or in a car’s engine.

    Be advised that this is just a rough calculation. If the concern is CO2 emissions, burning natural gas produces less CO2 per unit of energy released, so electric generation might be better than a gasoline engine. However, there are gas-powered vehicles too so an apples-to-apples comparison would use those.

    Another thing to consider is that producing the batteries for electric vehicles is quite energy intensive. The article that accompanied the cartoon made the point that this factor could tip the balance making electric vehicles less efficient when total life cycle costs are computed.

    The bottom line is that electric vehicles only make a big difference if the power is not derived from burning fuel, e.g., using nuclear power. Conventional power plants and cars both rely on heat engines. The laws of thermodynamics apply. TANSTAAFL.

    Two answers:

    1. Most people don’t understand science.
    2. They would defend the claim by saying it means zero emissions right here. What happens elsewhere is not my concern.

  5. It is sad how many people fall for “nice thoughts and sentiments” rather than facts. They don’t understand how things happen and way a magic wand. Take the health care debate. Giving health care to all doesn’t take into account the need for bigger facilities and more health care providers. It is “Let them eat cake.” for the 21st century.

  6. Unicorn tears? What happens when the unicorns are no more?

    Ya’ know that happened once and none were left until they crashed at Roswell.

  7. G.D.:

    The green economy comes to a screeching halt. Or maybe it gradually grinds to a stop: not with a bang, but a whimper. The greenies are the hollow men.

    Pretty lies are more pleasant than ugly reality.
