US Carbon Emissions Hit 20-Year Low 245

Freddybear writes "A recent report from the U.S. Energy Information Agency says that U.S. carbon emissions are the lowest they have been in 20 years, and attributes the decline to the increasing use of cheap natural gas obtained from fracking wells. Michael Mann, director of the Earth System Science Center at Penn State University, said the shift away from coal is reason for 'cautious optimism' about potential ways to deal with climate change. He said it demonstrates that 'ultimately people follow their wallets' on global warming. 'There's a very clear lesson here. What it shows is that if you make a cleaner energy source cheaper, you will displace dirtier sources,' said Roger Pielke Jr., a climate expert at the University of Colorado."

      And you don't think the Asians will seize upon the opportunity save money by adopting fracking techniques themselves? The west may be ahead of the curve with regard to petrochemical energy production but I really don't see any nation leaving money on the table.

    Sure, that's what everyone's been saying. The disagreement is over how to get there. Should we offer insurance guarantees for nuclear power plants? Should we mandate feed-in tariffs for household solar? Should we loosen restrictions on fracking? Should we increase science funding for alternative energy R&D? Should we institute a carbon tax?

      So far, the strategy has been to cause all energy costs except those from "green" energy sources to, as Obama is famously quoted as saying; "necessarily skyrocket".

      That's where I have a problem. Making "green" energy cheaper and more practical is a win and something I'd applaud, trying to force it by instead making everything else too expensive is stupid and hurts people, especially the poor, and the economy in general.

      Yes to all! But for the fracking, heavy monitoring would be good, too. The point being that gas is bad, fracking dirty, but all in all a much better choice than coal.

      But nuclear plants? Yes: it is the only carbon-free large-scale dense energy producing plant you can deploy anywhere. Feed-in tariffs for solar? Yes, you want as much solar as you can, because that forces the upgrading of the grid, and improves resilience. It is clean, too. Science funding? How can there be a debate. Is there any case of science funding which is a bad idea?

      I don't understand how there is a disagreement: all of theses are possible, they don't contradict each other, and could be done simultaneously.

        The fact that you can't price perfectly (particularly since there is no market here) doesn't mean you can't price at all. Right now, we price CO2 emissions at 0. For those who agree on the basic premise that CO2 emissions are a problem, 0 is obviously too low a price.

    We are running on overbuilt capacity from the 1960s. After that it became very, very expensive to build a large power plant - with most of the new costs being public protests and public comment sessions that turned into more and more evironmental impact studies. Often the result was the project was abandoned.

    In Arizona and Illinois (both places I have lived) the solution was simple: build "peaker" plants that run on natural gas and build them up over time from 200MW to more like 1000MW over time. This still results in a lot of protest activity but governing bodies are far more likely to ignore protests when the plant has been safely and cleanly operating for five years or so when it comes time to expand.

    The problem is that this is just a delaying tactic that will not solve the problem in the long run. Most parts of the country could use another 2000MW of capacity right now. Certainly if the economy recovers there will be considerable need for more and more electric power which today simply isn't available.

    It is just barely possible today to build a data center that is independent of the grid but the costs for the battery storage are huge. Solar PV generation is constantly being touted as a solution, but the only way it is a real solution would be to have it on a lot of homes and other buildings - a lot meaning probably over 50% of them. Unfortunately, this doesn't address the grid problems at 5-9 PM when everyone gets home, turns down the air conditioner temperature and turns on the microwave and the washing machine. To fix that we are going to need capacity that doesn't depend on the sun and today's grid-tied PV systems do not address that at all.

    One way out of the coming capacity crisis would be to have a big switch at the power company office: Day (offices) and Night (homes). This is literally what we might be facing soon. The problem is that we could easily have this kind of capacity problem in five years. It takes five years to build a new coal plant without any public opposition - and there would be plenty no matter where it was going to be built. It takes more like ten years to build a nuclear plant and we almost certainly do not have ten years before really running into a big capacity problem. We also need maybe 20-30 new plants coming on line in five years and we haven't even started building them.

    The power companies really don't care. They will not be the enemy when you find your refrigerator doesn't run during the day and there is a new box that shuts off your house power whenever the capacity is needed. You can bet their PR departments and outside agencies will be working overtime to make sure someone else gets the blame.

    But hey, if we don't build any new plants you can bet everyone will be shouting about how our CO2 emissions are down.

      The solution is distributed solar. Solar pays back in under 5 years now with a lifetime of 20+. The only problem with solar is that the energy companies (almost all privatized now) see solar as a threat, so they continue to push the "it just doesn't work" press releases. Despite the fact they are all lies, people still believe, so long as it lines up with their personal philosophies.

      Grid tied solar on homes would solve the power issue. Buy the dumped panels from China for the initial installation, and ramp up domestic production for replacement parts (as 20+ year life is good, but still means you need to replace about 5% per year forever). Distributed solar will take care of almost all our problems. We may end up with the (good) problem of more peak generation than demand, in which case we'd need to invest in some sufficient storage (China uses hydro storage, and it's quite effective - yes, I've been to Tien Shi and seen the production facility). Enough of that stable enough, and we could decrease baseline production.
      • Parent is correct. Distributed power is a THREAT to centralized power and that is one reason there has been zero interest in technologies that are disruptive-- it is like expecting Microsoft to support Linux.

        If every house was partially covered in solar panels we would have a totally different situation that we do today. We wouldn't need wind or nuclear. There would be a demand for power STORAGE so instead of a nuclear plant you would have probably also centralized big corporations which sucked up your che

  • I keep hearing from conservatives that we can't do anything about climate change or reducing CO2. Natural gas has long been proposed as superior to oil because of releasing far less CO2. Fracking is dirty but we were producing plenty of natural gas before fracking. Fracking simply caused a glut and increased profits. Other factors like the reduction in driving mimics more efficient cars so we don't have to stop driving to make a difference. I just read we could offset all the cars just by grass feeding cows

      That is what you heard.

      That's not what they said.

      Conservatives have long claimed there is no need to spend extra money to reduce CO2. They said there would be no benefit in ham-stringing first world countries in many ways to reduce a gas that may not even be causing a problem.

      And as it turns out, they were correct. If we had adopted Kyoto the U.S. would have a far worse economy than we have today, with many additional regulations imposed on businesses - when it turns out those additional regulations were never even needed.

      Over time alternative energy WILL naturally overcome traditional sources just in cost benefit alone, there is no need to hurt the productivity of countries to make that happen.

      • Rhe countries that adopted Kyoto protocolls have far less economic problems than the USA. How do you explain that?
        Productivity has nothing to do with the way how energy is produced. It also has not very much to do with how much energy you use for producing something.
        The contrary is true. The more you produce for the same amount of energy *or* the less energy you use to produce the same, the more efficient/productive you are.

      • "Over time alternative energy WILL naturally overcome traditional sources just in cost benefit alone, there is no need to hurt the productivity of countries to make that happen."

The problem is, by that time we have burn so many of both that climate change might be irreversible and well going thru. The problem is that conservative lacks UTTERLY in insight, they see their ow

  • I work at a coal plant. This year alone the overall power requirement for our area had been lower than the historical average. Yes, we did hit a peak generation record this year as well, but it's been a much milder year than normal.

    We've also seen the cost of natural gas fall to the point where it was cheaper to leave the coal plants on standby and run the natural gas plants for the power demand.

    This year we've run about 50% less than last year.

    • 50%? Seriously? *boggle* That's a serious drop. That's a huge drop, considering the population is the highest it's ever been. Or does your plant serve one of the areas that has lost population? Ohio and Michigan both have lost so much population over the past decade that they lost Congressional seats.

    I remember reading an article many years ago - long before the global warming scare - that pointed out that moving to lower carbon fuels was a long-term trend. Industry started out with coal and charcoal, essentually pure carbon. Then it moved on to oil, which contains a mix of carbon and hydrogen. Natural gas was up-and-coming, with 1 carbon to 4 hydrogens. The article assumed that the future held nuclear and solar, both of which are essentially zero-carbon.

    Aside from the hiccups with nuclear (justified or not, depending on your point of view), the article seems to have been pretty prescient.

    Only if we close the plants down. If the economy comes back soon and these things are still operational, they'll turn them back on.

    We should strike while the iron is hot and get these things closed. It's very easy to make a gas plant, we can have ample capacity in time for a resurgence in industry.
