This is very interesting – while we were out sailing around New Caledonia we missed Barry Brooks’ post A Necessary Interlude, where Barry explains a refocusing of Brave New Climate blog. Specifically, Barry wants the conversation focused on energy policy that will work in the real world.
Near the end of the post Barry succinctly summarizes his view of the energy options — this is so good I have reproduced that segment here. The emphasis below is mine, because my perception is Barry has worked his way through the same study that I have, with the same conclusions:
I am vitally interested in supporting real solutions that permit a rapid transition away from fossil fuels, especially coal (oil will, at least in part, take care of itself). If the conclusion is that wind/solar cannot meaningfully facilitate this transition, why bother to promote them? Now, I should make one thing quite clear. I am not AGAINST renewable energy. If folks want to build them, go for it! If they can find investors, great! Indeed, I’m no NIMBY, and would be happy to have a conga line of huge turbines gracing the hills behind my home, just as I’d be happy to have a brand spanking new nuclear power station in my suburb. But why should I promote something I have come to consider — on a scientific and economic basis — to be a non-solution to the energy and climate crisis? That doesn’t make sense to me.
To your questions:
1. Coal with CCS — doomed to failure. Why? Because the only thing that is going to be embraced with sufficient vigour, on a global scale, is an energy technology that has the favourable characteristics of coal, but is cheaper than coal. CCS, by virtue of the fact that it is coal + extra costs (capture, compressions, sequestration) axiomatically fails this litmus test. It is therefore of no interest and those who promote it can only do so on the basis of simultaneously promoting such a large carbon price that (a) the developing world is highly unlikely to ever impose it, and (b) if they do, CCS won’t be competitive with nuclear. CCS is a non-solution to the climate and energy crises.
2. Natural gas has no role in baseload generation. It is a high-carbon fossil fuel that releases 500 to 700 kg of CO2 per MWh. If it is used in peaking power only (say at 10% capacity factor), then it is only a tiny piece in the puzzle, because we must displace the coal. It it is used to displace the coal baseload, then it is a counterproductive ’solution’ because it is still high carbon (despite what the Romms of this world will have you believe) and is in shorter supply than coal anyway. Gas is a non-solution to the climate and energy crises.
3. The developing world lives in Trainer’s power-down society already, and they are going to do everything possible to get the hell out of it. The developed world will fight tooth an nail, and will burn the planet to a soot-laden crisp, rather than embrace Trainer’s simpler way. Power down is a non-solution to the climate and energy crises.
4. It is nice to imagine that renewables will have a niche role in the future. But actually, will they? They don’t have any meaningful role now, when pitted in competition with fossil fuels, so why will that be different when pitted fairly against a nuclear-powered world? I don’t know the answer, and I don’t frankly care, because even if renewable energy can manage to maintain various niche energy supply roles in the future, it won’t meet most of the current or future power demand. So niche applications or not, renewables are peripheral to the big picture because they are a non-solution to the climate and energy crises.
5. Smart grids will provide better energy supply and demand management. Fine, great, that will help irrespective of what source the energy comes from (nuclear, gas, coal, renewables, whatever). Smarter grids are inevitable and welcome. But they are not some white knight that will miraculously allow renewable energy to achieve any significant penetration into meeting world energy demand in the future. Smart grids are sensible, but they are not a solution to the climate and energy crises.
To some, the above may sound rather dogmatic. To me, it’s the emergent property of trying my damnedest to be ruthlessly pragmatic about the energy problem. I have no barrow to push, I don’t get anything out of it — other than I want this problem fixed. I don’t earn a red cent if nuclear turns out be the primary solution. I don’t win by renewables failing. The bottom line is this — if this website is looking more and more like a nuclear advocacy site, then you ought to consider why. It might just be because I’ve come to the conclusion that nuclear power is the only realistic solution to this problem, and that’s why I’m ever more stridently advocating it. This is a ‘game’ we cannot afford to lose, and the longer we dither about with ultimately worthless solutions, the closer we come to endgame, with no pawn left to move to the back row and Queen.
So what can you expect from BNC in the future? Much more on nuclear power (both Gen III and Gen IV), obviously, since I now consider this technology to be the core climate change solution — whilst openly acknowledging the yawning gulf between the scientific understanding of nuclear power and the public’s perception. This must change, and I hope, in my modest way, I can be an agent for that attitudinal shift. I also plan to launch an extended series on renewable energy, with an aim to break down the often complex and multifaceted critiques being made, into simpler, single-issue chunks, which can be more readily pinned down and understood. I will also profile some of the less well-developed low-carbon technologies, such as tidal, wave, microalgae, and geothermal, and speculate on their possible future roles. I hope in this way that I’ll be able to reinforce people’s understanding of why I no longer hold renewable energy to be a primary solution — and yet, by the same yardstick of maintaining intellectual honesty, I’ll also try my very best to keep an open mind to unconsidered possibilities and caveats that are raised by commenters (be these against nuclear energy, and/or for renewables). As I said, healthy thought should never cease to evolve.
Lastly, there is an interesting conversation about marketing strategies in the comments — i.e., how to best educate and persuade the voters to back nuclear power. Search for e.g., “Fran Barlow”, “Finrod”, “David Walters”.
