Two Google Engineers Say Renewables Can't Cure Climate Change

_Sharp'r_ writes Two Stanford PhDs, Ross Koningstein and David Fork, worked for Google on the RE<C project to figure out how to make renewables cheaper than coal and solve climate change. After four years of study they gave up, determining "Renewable energy technologies simply won't work; we need a fundamentally different approach." As a result, is nuclear going to be acknowledged as the future of energy production?

The U.S. nuclear industry had 69,720 tons of uranium waste as of May 2013, with 49,620 tons in pools and 20,100 in dry storage, according to the Nuclear Energy Institute industry group.

      Spent nuclear fuel is about 95 percent uranium. About 1 percent is other heavy elements such as curium, americium and plutonium-239. Each has an extremely long half-life — some take hundreds of thousands of years to lose all of their radioactive potency.

      And all of those sites are close to 50 years old with no maintenance and with no fuel storage because of the veto of Yucca mountain, etc....

      Yes, there are some nasty by-products of nuclear power. But we have the technology to clean these sites up and store or re-process the waste.

      It's not the engineers' fault; It's rare that I've seen as big of a misrepresentation of an article outside of say Russian state propaganda that I've seen with this Register article. Starting with the title.

      The original article absolutely, positively does not say in any way, shape or form, "Renewable energy 'simply WON'T WORK'" or "Whatever the future holds, it is not a renewables-powered civilisation: such a thing is impossible."

      The actual article says something very, very different. The engineers went into the project hoping that if we make the incremental improvements to make renewables as cheap as coal, then there will be a mass-switchover to renewables and CO2 levels will be held down. Except that that doesn't work. Why? Because of lead times. People who have existing coal power plants for example aren't just going to take them down because new renewables projects are cheaper than new coal plants. You need to get the price down well below that of coal to where it justifies them throwing their already-invested capital costs out the window. Without doing that, your switchover rate is limited by how fast power plants go offline, which is a very long time. So in their "as cheap as coal" scenario, they only get to a 55% emissions cut by 2050. They were hoping that'd keep the world under 350 ppm. But not only does the world still hit 350 ppm in that scenario, but it continues to rise. Hence, the hypothesis that getting renewables as cheap as coal is sufficient to prevent major climate change is suggested to be wrong.

      What that DOESN'T say in any way, shape or form:

      1) Renewables "WON'T WORK"
      2) Renewables "don't help prevent climate change"
      3) There's no scenario in which renewables can prevent climate change

      What they call for are several changes.

      1) They feel that focusing on preventing emissions with renewables isn't enough, that you need active CO2 scrubbing as well.

      2) They call for renewables investment to adopt the "Google Model": 70% core business, 20% related new business, 10% risky disruptive new technology. This is versus conventional investment which is 90% core business (aka incremental improvements), 9,9% related, and 0,1% disruptive. They think this provides better odds for renewables or other technologies to stop climate change because incrementally improving down to the price of coal - while it'd have a big impact on CO2 emissions rates - still won't keep levels down below 350 ppm.

      Does this even resemble the Register article? Nope. Not even a little bit.

    In reality, nukes are terrible as backup power. Just assuming you have a plant that can ramp up and down quickly (most can't), nuclear plants are almost all capital cost. Hence they need to run at a high capacity factor to pay back the investment; it doesn't pay to idle them. But if you're wanting to use them as gap filling in low wind/solar times, then that's exactly what you're suggesting be done - sit idle until more power is needed. It's a terrible use of a nuclear plant.

    Pumped hydro isn't that expensive. It's currently the cheapest option out there by a good margin (except for uprating already-existing conventional hydro). But other techs are trying to beat it. Probably the best thing you can do is simply have a powerful HVDC grid so you can move power between different geographic regions and to use different types of renewables techs. The randomness goes way down when you do this. NG is commonly used as a peaking fuel, and I see no problem continuing to do this (instead of doing energy storage) if you can keep it down to an average of under 10% or so of the total generation mix. It's low carbon to begin with and modern NG peakers can hit upwards of 60% efficiency once warmed up. So 90% renewables, 10% efficiently-used NG, you're talking near total elimination of electricity-related CO2 emissions.

For you true believers, please cite the scientific paper that convinced you beyond doubt that CO2 is the dominant driver of climate warming. Note, it your paper uses computer models or least squares curve fitting, it is worthless for proving causality.

      Yeh, a bit of throwing the baby out with the bath water. They gave up because they couldn't make renewables cheaper than coal. However, if you really want to help mitigate(I emphasize mitigate based on the article's information, RTFA) CO2 output, you might be willing to pay more for renewable energy and not have to suffer the economic loss of climate change impact later(that of course being a whole different argument).

      It was a business venture, and they knew it wouldn't succeed based on morals alone. It'd have to be cheaper than coal to be viable, and coal is dirt cheap, cause there's a ton of the stuff. It's alot more available than oil is, it's just not the nicest stuff to burn on the same planet you happen to live.

      They did NOT say to abandon AE. They said that just as certain that global warming is occurring, that it is impossible to solve with only renewables. And considering that the human population increases, as does its demand for more energy, it is obviously impossible to grow AE fast or economical enough. Nukes really have to be added to the mix. Not large ones, but small ones similar to what Babcock has with mpower.

    Actually a lot of environmentalists are in favour of nuclear power. It's those investors and their "risk averse" nature that don't want to throw billions of dollars at something that might lose them money, especially when there are better opportunities.

    The UK has to pay power companies to build new nuclear plants, and still only one player is interested. They are that bad of an investment. Nuclear is unsuitable for commercial operation, and always requires government funding to get built.

  13. Nuclear won't be acknowledged as a solution. by radtea · · Score: 4, Interesting

    Nuclear won't be accepted as a solution until people who claim to believe that climate change has the potential to end civilization accept that the only proven technology capable of replacing base-load coal is nuclear, and that climate change is a technological problem, not a social problem.

    This will take a long time.

    The green activist movement is completely dominated by Naiomi Klein-style social engineers who don't care one whit about the environment, but who see it as a useful tool for defeating global capitalism. Thus their opposition to any technological solution to the problem of CO2 emissions whatsoever.

    Now that climate change is increasingly widely acknowledged as a real issue--the Pentagon takes it seriously, can you get realer than that?--the green activist community will increasingly be seen as the major impediment to solving the problem. The question is: will we push these utopian socialists aside quickly enough to save the planet?

    You're paper is based on the same data. The debunking clearly shows the why what you're saying isn't accurate.

    That CO2 and NO radiate heat doesn't make them 'cooling' agents in the way you're trying to imply. It means that they prevent the passage of heat energy, on the outside they radiate heat into space when they are hit by a solar flare. SOME energy does get through and the agents now keep that energy locked up longer because they restrict escaping heat.

    ANYTHING hit by a solar flare is going to heat up and then start radiating heat away from itself. CO2 and NO block much of the Suns energy, we'd fry if we had all the energy coming in. That again doesn't make them 'cooling' agents. They are insulators keeping heat on whatever side of the border it currently is. If you pile more blankets on your bed, you get warmer.

    That's what we're doing with CO2 in the atmosphere.
