I don’t know how many times I see green=biodiesel. No it does not. Perfect combustion produces C02 and H2O. Bio diesel is very inefficient, but even at its most efficient, it would be adding more CO2.
CO2 is required by the photosynthesis process. Breathing and burning put more CO2 in the air, plants take the carbon out of the air, and return the Oxygen to the air. Burning is done to provide things to animals. Both processes that add CO2 (burning and breathing) are done by, and for, animals. The only natural process that removes carbon is done by plants (animals get the carbon by eating the plants). If you assume that global warming is real, then the only logical conclusion is too many animals, not enough plants.
The real cause of rising CO2 levels? Population growth. Not even Al Gore is willing to talk about that, but that’s what it is. Al Gore showed us those sharply-rising graphs in An Inconvenient Truth, he even showed the corresponding population growth graph, but he didn’t suggest that we lower the population.
We need less people:
- Let’s say you lower your CO2 production by 50%, but you also have children, (“All right: you lower your CO2 production by 50%, but you also have children.”) and your children have children, and so on. So, you divided your CO2 production in half but you potentially are responsible for creating 100 times (or… pick a number) that amount of CO2, because you created descendants, that created descendants, and so on, and they all use energy.
- Why aren’t folks talking about this? …because it means telling people not to have babies, and people will not stop having babies.
- Read Maybe One.
Plants breath CO2: yes, that “evil” carbon footprint is potentially good for plants. The natural carbon-sequestration solution isn’t all of this sci-fi, it is more plants, but more plants means less room for other things that people want. Raising livestock uses more energy than raising plant-produce. If we raise less livestock and more plant-produce, then the plants will be sequestering CO2, and less energy will be wasted creating food.
I love electric cars, and I would really like an electric motorcycle. I have been replacing our crazy Lutron switches (these things give new meaning to the words “poor user interface“) with ones that are compatible with CFLs, and using the CFLs. I would rather get electricity from wind, solar, and hydro.
Carbon dioxide is not toxic though. It’s a natural part of our world that is absolutely essential for life on earth. No CO2 means no plants. No plants means we all die. Admittedly too much of anything can be bad for you, but I don’t want to hear about my “carbon footprint” from people that aren’t willing to do what’s necessary to change their own.
Many people think that ethanol is OK, because the CO2 that gets put back into the atmosphere was removed from the atmosphere, so there is no net gain, but that is true for ALL fuels. ALL CO2 came from the atmosphere. Besides, it takes more than one gallon of oil to create the nitrogen based fertilizer needed to create less than one gallon of ethanol, let alone the energy used to transport it, process it, etc. …and ethanol has a lower energy content than gasoline.
I love properly designed electric vehicles. Powerful electric motors move diesel trains, so they can sure move an automobile, or a motorcycle, but electric vehicles are still much more expensive than gasoline-powered vehicles.
Who killed the electric car? You don’t need a movie to answer that question. The batteries would have cost more than a new car to replace, yet needed to be replaced too often. Did the movie mention that? No? (I actually got to see GM’s electric car, the EV1, before it was unveiled. I worked at the GM Powertrain Engineering Center in Warren MI.)
I like wind farms, and solar, and geothermal, but technology is not enough.
