    Energy consumption will be limited by conservation (higher prices, expensive and inefficient government regulations and policies, etc.) and efficiency (technology, smaller houses, smaller autos, etc.).

    Our standard of living is lower today than in 2007, and it’ll improve much more slowly at best for several decades (given the Baby-Boom retirement, along with regulations, taxes, and government spending).

    it’s going to be very, very easy to tell when an alternative technology has become competitive with hydrocarbons.

    it will spread like wildfire.

    it is also very easy to tell when a technology is not ready as it requires massive subsidies and still does not get adopted much.

    wind farms are really just subsidy farms. solar is mostly the same way.

    the one exception here might have been nuclear, which can produce electricity quite competitively with the rest of the baseline grid, but has been basically drummed out of contention in the US through impossible regulation and permitting requirements.

    1. I wonder, is it a case of current alternatives simply not being viable or is it a lack of foresight and patience for these new technologies to get off the ground or are they viable but mismanaged/funded?

      or a combo?

        Some of these “new technologies” are nothing more than recycled failures from Jurassic Park and earlier. Windmills and power from the sun are two good examples. Even with the application of modern 21st century technologies and billions of taxpayer subsidies, they remain uneconomic, unreliable and inefficient. They require massive and very expensive back-up power sources in order to be considered realistic power alternatives capable of reliably running a modern economy. You simply can’t send 5,000 factory, mill, plant, foundry, warehouse, food service and mine workers home because the lights went out, the air conditioning is down, the production lines won’t move or the toilets won’t flush.

        The future of alternatives, at least for the next 100 years, is that they will remain alternatives.

        moe-

        apart from nuclear, the current alternatives are simply not viable.

        many never will be.

        wind is a great example. it is NEVER going to be viable. not ever. the reality of the power over sweep equation means that wind will never produce more than about 15-20% of faceplate rating even in optimal locations. worse, it is intermittent and difficult to predict which means it can only even be surge power, not baseline.

        solar can likely be made to work at some point if cells can be made efficient enough and price drops.

        geothermal has potential.

        tidal/wave etc looks really tough. the realities of the ocean tend to really play hell with large pieces of electrical equipment.

        there is a ton of energy there, but all the projects i have seen have been pretty dramatic failures thus far.

        there has doubtless been some severe mismanagement as well, but that is the nearly inevitable result of big government subsidies, grants, and loans.

        when funding is not based on return, you get malinvestment, nepotism, and theft. think: solyndra.

        1. I suppose there is always the chance that human ingenuity (as Che has mentioned) may save some of these options from the rubbish pile.

          1. morganovich

            moe-

            i suspect it will. we live in an ecosystem that is quite rich in energy relative to what we use.

            it’s just a question of figuring out how to harness/produce it cost effectively.

            of course, there is always that wild dark horse cold fusion.

            if we figure that out, every other energy source will become irrelevant. power will become so cheap and abundant as to change everyhting.

            when and if that happens is anyone’s guess, but humans are pretty innovative.

      3. Jon Murphy

        I think, Moe, that it’s a combination of the techs not being viable, and some mismanagement.

        Wind power requires a back-up source of power for when there is no wind.

        Solar requires very large and expensive panels to produce a relatively small amount of energy.

        Hydro’s not bad, but it requires a powerful river.

        Additionally, for all three, the space they require to produce the same amount of energy as fossil fuel is rather large.

        There is also a matter of cost. Fossil fuels are amazingly cheap and effective. I read an article that said for every one unit of energy used in the production process for oil, the oil generates 6 units back (ratio 1:6). For renewables, that ratio is closer to 1:0.9 (for every unit of energy expended, 0.9 units are created).

        But, for the sake of argument, let’s give the government the benefit of the doubt here. Let’s assume that alternatives really are the energy of the future and the graph Dr. Perry posted is completely wrong. The government has been giving subsidies to companies and individuals so the cost can fall. Well, the tariff on Chinese solar panels isn’t doing renewables any favors. If the problem is that the costs are too high, and the Chinese are willing to sell us solar panels for pennies on the dollar, how will blocking these imports help renewables become cheaper? That’s just bad management right there.

        1. Hydro’s not bad, but it requires a powerful river.

          And if I’m not mistaken, I believe something like 75% of all potential hydro power in the US is already harnessed. Beyond that there are serious navigation and environmental issues, and the problem of flooding large areas to create reservoirs.

      4. A very good book on the viability of various energy sources is Robert Laughlin’s Powering the Future

        http://large.stanford.edu/

        Some alternatives are simply not viable because they are not dense enough to matter. Others will come on line as we cross over economic thresholds. Overall, the book is very positive, since much of the technology we need is already here.

        1. Jon Murphy

          [S]ince much of the technology we need is already here.

          This is one thing I like, Rufus. Forgetting how one feels about alternatives, we do have the technology to tap into them. This isn’t theoretical stuff. Since the tech already exists, everything from here on out is, in theory, improvement!

    I wonder how much we could reduce consumption if we opened the urban transit market to competition?

    1. Jon Murphy

      I second that motion

      1. Let’s open *all* markets to competition, including those for services currently monopolized by government.

        Yay choice!

  4. While we were on the topic of energy:
    Quiz: What’s the worlds largest man-made floating object?

    Answer

    1. Oh. I guessed it was this thing.

    2. I’m going to guess the floating plastic garbage dump in the ocean.

    Another kind of ‘fracking’, this produces geothermal energy

    “One option for transitioning away from our current hydrocarbon-based energy system to non-carbon sources is geothermal energy – from both conventional hydrothermal resources and enhanced geothermal systems,” said Zoback, a senior fellow at the Precourt Institute for Energy at Stanford.

    Unlike conventional geothermal power, which typically depends on heat from geysers and hot springs near the surface, enhanced geothermal technology has been touted as a major source of clean energy for much of the planet.

    The idea is to pump water into a deep well at pressures strong enough to fracture hot granite and other high-temperature rock miles below the surface. These fractures enhance the permeability of the rock, allowing the water to circulate and become hot.

    A second well delivers steam back to the surface. The steam is used to drive a turbine that produces electricity with virtually no greenhouse gas emissions. The steam eventually cools and is re-injected underground and recycled to the surface. In 2006, Tester co-authored a major report on the subject, estimating that 2 percent of the enhanced geothermal resource available in the continental United States could deliver roughly 2,600 times more energy than the country consumes annually.”Watts Up With That

    1. morganovich

      a question:

      geothermal looks to have a great deal of promise. the basic physics of it are obvious and proven.

      so what is holding it up? why is it not in broader and rapidly expanding use?

      this is not an area in which i have done any real work, but my intuition is that there is a serious issue here somewhere otherwise we’d be seeing rapid adoption.

      is it cost? something technical in drilling so deeply? somehting regulatory about earth gasses?

      what’s causing the holdup?

        Has Al Gore established a position in a geothermal company yet?

        The man who was within sight of the presidency 12 years ago has transformed himself, becoming perhaps the world’s most renowned crusader on climate change and a highly successful green-tech investor.

        Just before leaving public office in 2001, Gore reported assets of less than $2 million; today, his wealth is estimated at $100 million.

        Gore charted this path by returning to his longtime passion — clean energy. He benefited from a powerful resume and a constellation of friends in the investment world and in Washington. And four years ago, his portfolio aligned smoothly with the agenda of an incoming administration and its plan to spend billions in stimulus funds on alternative energy.

        The recovering politician was pushing the right cause at the perfect time.

        Fourteen green-tech firms in which Gore invested received or directly benefited from more than $2.5 billion in loans, grants and tax breaks, part of President Obama’s historic push to seed a U.S. renewable-energy industry with public money. — Fox News

      2. Discover had a piece on Geothermal – hold-ups were due to finding “hot spots’ – or “hot enough spots”. Some wells had to go up to 7 miles down – costly.

        I’ll see I can find a link.

    Moe says: “I wonder, is it a case of current alternatives simply not being viable or is it a lack of foresight and patience for these new technologies to get off the ground or are they viable but mismanaged/funded? or a combo?”

    Why don’t you invest in an alternative energy firm and find out?

    1. I do have money in a firm called Solindra…or something…I should check on it.

      1. Don’t we all?

        1. I think we did.

          1. Jon Murphy

            Speak for yourselves. Up until this past year, I was one of those free-loading 47%-ers! :-P

          2. Your parents may have had some money “invested in our future” as they call the outright theft of peoples property

  7. Hell_is_Like_Newark

    Remove hydropower from the graph (which is the vast majority of ‘renewable’ power generated), the cost of green energy vs. its output will look even worse. Much worse.

    Without subsidies and government mandates (requiring purchasing of expensive green power) wind and solar would disappear overnight.

  8. lets just be glad we still have hydro power that and we aren’t left with only solar and wind eh
