Transportation

Planes, Trains, and Automobiles Have Become Top Carbon Polluters (technologyreview.com) 235

Transportation is likely to surpass the electricity sector in 2016 as the largest source of carbon dioxide emissions in the United States, according to a new analysis of government data, MIT Technology reports. From the article: In 2008, the global financial crisis caused widespread declines in energy use. In the U.S., that coincided with the early stages of a large-scale shift away from coal toward cleaner-burning natural gas as a way to generate electricity. As a result, carbon dioxide emissions from the electricity sector have continued to decline from their 2007 peak, even as the economy has resumed growing. The trend line for the transportation sector is less encouraging. Transportation emissions have begun rising as the economy rebounds. John DeCicco at the University of Michigan Energy Institute, who wrote the study, attributes the rebound we've seen during the past four years to straightforward causes: economic recovery and more affordable fuel prices. Vehicle sales numbers have been rising for several years, in particular for trucks and SUVs, and people are traveling more miles.

    As processes improve large scale projects such as factories and power generation tend to get more efficient as predicted but it's hard to get the same economies of scale on smaller systems like cars. It's death by millions and millions of cuts instead of by one massive blow. I'm sort of contributing by owning a Volt and have managed to go gas free for most of spring, all of summer and fall until winter when it switches over to inefficient gas engine because it needs the waste heat. To be honest thou, I never entirely went with the Volt to save gas even thou it does as a bonus. EV's are just incredibly smooth cars to drive and lack of engine noise is really nice. Hopefully more folks realize the Volt is a good option and EV's become more popular.

    • Wherefore dost thou use archaic forms?

      Oh you mean though.

    • No, what GM needs to do is license their technology from the Volt to other automakers. The biggest problem with the Volt is that it's made by GM, the same company that made defective ignition switches for years and intentionally hid this and murdered people so they wouldn't have to pay for a recall. They're also known for making cars that don't last long and have crappy interiors that fall apart in a few years, and very ugly exteriors too, not to mention very poor driving dynamics.

  • Planes and rockets are the only tough bits. We can electrify cars and trains with no problem. Iron refining and cement are only a little more difficult. At least that will give us more time to work on the planes.

    • Actually, while there is a case for not using coal just to produce energy, producing metals out of their ores is a very valid use of coal. As it is, that carbon dioxide is trapped in the mines - never gets out in the quantities that, say, factories produce when burning coal for electricity. As long as we keep digging up iron ore, bauxite, copper ore and other metal ores, we'll need comparable amounts of coal to extract those metals. And that is the only thing that coal should be needed for.

      You have to "decarbonize" limestone (CaCO3) to Calcium Oxide (CaO) to make cement. You _cannot_ make cement without producing a lot of carbon dioxide, even if your energy source is carbon-free.

    I live not too far from major highway. Noise and pollution from automobiles worry me. The electric revolution cannot come soon enough. Also, I don't know if it is old age or something else, but those extremely loud motorcycles annoy me to no end. I wish I could stop them and beat the shit out of them. Anybody else feel that way? And why the hell do these riders intentionally make their bikes so loud?

      Electric cars aren't going to help your noise problems. With modern cars, most of the noise comes from the tires at high speeds. Electric cars use the same tires as gas cars.

    • And why the hell do these riders intentionally make their bikes so loud?

      Because a loud bike is a known bike. If you choose to ride a motorcycle then your greatest risk is other drivers. By having a loud bike it's harder for them to not know you are there.

    I take this article to be good news. Renewable energy is finally contributing to the grid well enough to where emissions will drop below the carbon emitted from transportation. This is excellent progress and excellent news.

    Now, here's how you fix the transportation part. A wonderful article you can only find on the Wayback Machine, from 2004. UNH Biodiesel Group, Widescale Biodiesel Production from Algae, Michael Briggs, University of New Hampshire, Physics Department. [archive.org]

    It's my favorite paper on the topic and I'll take any opportunity to post it.

    TL;DR - if we really wanted to, we (meaning the USA) could utilize biodiesel entirely for our current transportation needs. It would be 100% renewable, carbon neutral, and all the money spent would stay inside our own borders. And any other country could easily do the same. There is absolutely NO need to haul oil out of the ground anymore.

    Check the math in the paper. We really could do this.

    • I'm rather skeptical that the biological approach beats the industrial one. Especially with future availability of intermittent cheap electricity surplus and improved water splitting, more options could be available such as Sabatier or Haber.
      • Oh sure, it's not a sexy solution at all. I'd like to see a future with a Tesla in every garage and fusion plants dotting the landscape. And I do think we'll get there someday. But this approach does have the merit of being available today. It uses the petroleum infrastructure we already have in place, so no spin-up costs there. And it's 100% carbon neutral, which will become increasingly important in the next few decades.

        • But this approach does have the merit of being available today.

          No, it is not available today. What we have now are a handful of small experimental producers that make biodiesel at considerable cost for vanity consumers. The US military is buying a lot of this biodiesel and they are paying something like 4X the price they would for petro-diesel. I don't have a real problem with that since they are funding research that might prove useful in the future. I also don't have a problem with biodiesel research because the US military is also working on synthetic hydrocarbo

      Problem is the emissions. While it may be carbon neutral, other nasty stuff comes out if the exhaust, and people have to breathe it in.

      Electric vehicles are the best solution. Batteries are getting really cheap and are highly reusable and recyclable.

    The author concludes that our best hope to fix this trend is a return of high gasoline prices.

    IMO, that's ONE way it might change, but pretty much the WORST option.

    Personally, I'd rather see more people opt for electric cars or public transit because improvements were made in those areas, making them more desirable!

    High fuel prices punish the people who are already struggling, on tight budgets. If they need to drive a vehicle for any kind of delivery or taxi job (Uber, Lyft, etc.) - it means their costs go up, because they can't just "drive less". Often, it's the same story for someone who relies on a car to commute to/from work. All those people telling you to carpool to work or take a bus aren't being that realistic. In many cases, you need the ability to haul things around in a trunk or back seat of a car that you don't get when using a bus or other mass transit, and you can't always find a workable carpool. It makes everyone pay more for package delivery too, harming your ability to get your asking price when you sell used goods on the Internet via sites like eBay. (It actually hurts the whole economy since pretty much every business relies on shipping in some manner. But it hurts individuals the most, IMO. The big companies do enough volume so they can negotiate pretty nice discounts with shippers like UPS or FedEx. They may pay more than they used to to ship goods, but it'll still be far less than you or I pay.)

    I know personally, I live around 50 miles from my workplace. I used to take the commuter train, but the combination of increased prices for it and reliability issues forced me to go back to driving. There are just too many times the train is really late due to freight train traffic that gets priority on the rails they use, or mechanical breakdowns. When I was waiting on the last train of the evening and it was one hour, then 1 1/2 hours, then 2, 3 and finally 3 1/2 hours late -- I had enough. (To add insult to injury, it was cold and raining outside, and the station platform is outdoors with no good shielding from the wind or rain.)

    What I *have* done is to express my plight to my bosses at work, who finally agreed to let me start working from home more often. That winds up letting me claw back all of that commuting time I lost before - as well as saving on travel expenses. So it's a win all around. But yeah -- I really tried to stick with the public transit option. They just don't have their act together enough to make it attractive.

      But but, higher gas prices CAUSES your outcomes.

      If gas gets too expensive, people in your town will demand either telecommunting and better non-personal travel options. If the economics of personal car driving becomes untenable, then people should start car-pooling (why aren't you?). Further, expand car pools into even cheaper daily bus routes. Further, enough bus services and all of a sudden new rail lines become another viable option. And all that's strictly driven through commerce and economics.

      • by swb ( 14022 )

        Bullshit.

        In Minnesota user fees (of which gas taxes are just a subset) doesn't cover the maintenance cost of the roads and less than half the total cost of the roads. And the bitching about deferred maintenance and delayed capital spending for roads is endless.

        Politically you would never get away with the $2-3 in statewide tax increase directly funneled to mass transit. The people who don't or can't use mass transit (ie, they live hundreds of miles from it) would never agree to a huge gas tax and the $4-6

      If we committed to gradually raising taxes on fossil fuels in a predictable way, we would encourage the purchase of more energy efficient vehicles. Even prices half of what they have in Europe would go a long way towards this. If you knew that in 10 years the minimum price per gallon would be $4-5, and that taxes would be going up ~$.25 a year until then, your next car purchase might be a smaller one than otherwise.

      High fuel prices punish the people who are already struggling, on tight budgets.

      This is why it ought to be a revenue neutral carbon tax where the revenues are distributed to everyone equally. Maybe your wallet wouldn't notice that extra $500 check from the government, but it would be a windfall for someone on a fixed income.

      • but it would be a windfall for someone on a fixed income.

        It will be a windfall for two groups: the people who never pay for any gas and get free money from other people, and the government employees who are hired to manage the program. The latter, by the way, is why such a system will never be "neutral" and never pay out as much as it takes in in additional taxes.

          Yes, and correcting negative externalities makes the market more efficient [wikipedia.org].

          ...and the government employees who are hired to manage the program.

          That's another good point: it would create jobs.

          So what's the downside?

          • Government employees are inherently unproductive.They suck up the livelihood of honest folk and produce nothing but their own excretions.

            "Creating jobs" without a full analysis of all effects leads to such silliness as the Broken Window Fallacy.

          • So what's the downside?

            The downside is that the claim that all money that is taken from the economy as the carbon tax would be paid back to the people. A large amount has to be skimmed from the top to pay the management. This makes it inherently unfair, and in large part a hidden tax, as it will increase the prices of anything that is transported or manufactured using energy.

    • High fuel prices punish the people who are already struggling, on tight budgets. If they need to drive a vehicle for any kind of delivery or taxi job (Uber, Lyft, etc.) - it means their costs go up, because they can't just "drive less".

      That doesn't mean it shouldn't be done, it just means that it shouldn't be done too quickly or without warning. People can adapt, by moving where they live, by relocating businesses, by switching to telecommuting, by carpooling, using mass transit (which may require transit buildout) etc. (and taxis can simply raise their prices to account for the higher fuel costs -- or switch to electrics). The key is to give people time to adapt, and let them know that they need to.

      Oh, there are far far worse options. Increasing the cost of something will decrease usage, starting with the least necessary usage. Also, a lot of supposedly "necessary" usage will eventually be reduced or eliminated, possibly after a painful transition. The price could be increased by placing a tax on it, and returning the proceeds to the people in a way that would minimize the damage to the most affected people or industries.

      Alternatives such as laws requiring carpooling, laws forbidding gasoline engines,
