Only Nuclear Energy Can Save the Planet (wsj.com)

Joshua S. Goldstein, a professor emeritus of international relations at American University, and Staffan A. Qvist, an energy engineer and consultant, writing for The Wall Street Journal: Climate scientists tell us that the world must drastically cut its fossil fuel use in the next 30 years to stave off a potentially catastrophic tipping point for the planet. Confronting this challenge is a moral issue, but it's also a math problem -- and a big part of the solution has to be nuclear power. Today, more than 80% of the world's energy comes from fossil fuels, which are used to generate electricity, to heat buildings and to power car and airplane engines. Worse for the planet, the consumption of fossil fuels is growing quickly as poorer countries climb out of poverty and increase their energy use. Improving energy efficiency can reduce some of the burden, but it's not nearly enough to offset growing demand.

Any serious effort to decarbonize the world economy will require, then, a great deal more clean energy, on the order of 100 trillion kilowatt-hours per year, by our calculations -- roughly equivalent to today's entire annual fossil-fuel usage. A key variable is speed. To reach the target within three decades, the world would have to add about 3.3 trillion more kilowatt-hours of clean energy every year. Solar and wind power alone can't scale up fast enough to generate the vast amounts of electricity that will be needed by midcentury, especially as we convert car engines and the like from fossil fuels to carbon-free energy sources. Even Germany's concerted recent effort to add renewables -- the most ambitious national effort so far -- was nowhere near fast enough. A global increase in renewables at a rate matching Germany's peak success would add about 0.7 trillion kilowatt-hours of clean electricity every year. That's just over a fifth of the necessary 3.3 trillion annual target.

    They have proven him right actually. Everything from increasing grid stability issues to decommissioning costs is becoming more and more of a question mark on both wind and solar as they become less of a boutique and more widespread adopted forms of power generations.

    And there are no solutions in sight to those problems as of yet.

      Agreed. When you're a hammer everything looks like a nail. I have trouble even imagining nuclear reactors safely run in "developing" countries like those in most of Africa. Just the thought of peppering Africa with such reactors is terrifying.

    And don't think for one second that wasn't the intention.

    Anti-Nuclear activist, including many in Congress, have done everything they can to gun up the nuclear power industry.

    As a technology, nuclear is only in it's very first stages.Promising technologies like breeder reactors that can burn nuclear wastes to almost inert piles or rock were arbitrarily outlawed. Promising avenues such as micro reactors are mired in red tape and make no mistake, lawsuits will follow them where ever they think of putting one.

    What is needed:

    1. Two to Three standard designs, vetted by some group of nuclear engineers as safe. Facilitates factory production of components
    2. Processes to fast track environmental reviews
    3. Limited indemnity for developers to prevent frivolous lawsuits.
    4. Some form of expedited processed in the courts to review lawsuits and settle them quickly.
    5. Reopen Yucca Mountain. Fuck Harry Reid. Hell, bury his soon to be dead ass in it.
    6. Ongoing research into new designs, module designs, etc.

    But let's keep investing into archaic unsafe technology and pollute the environment when they fail

    People like you spreading this complete strawman bullshit and generations of Greenpeace psychos before that are the reason that we have no modern, safe nuclear options. Updated designs using passive reactor safety, such as Generation IV, *can't* have an uncontrolled meltdown -- in the event of a problem, gravity automatically shuts down the reaction. Ask the French -- they generate 40% of their own power via nukes plus they generate electricity for a good chunk of the rest of Europe using nuclear. Please educate yourself instead of using 70 year old stereotypes about nuclear power -- because thanks to the misinformation you are spreading, we are stuck with ancient, unsafe reactor designs.

    Yeah, but when you need to plaster a third to half the country with wind and solar to even get close to providing enough energy, then even the most blind of idiots must realize that this is probably not going to be our salvation.

    Also: Do you believe the production of silicon for PV is not harmful to the environment? Especially in those amounts? Not to mention the question of whether we are even able to find enough raw materials for it.

    I agree that nuclear power has been done wrong in many ways. And we can now see that companies haven't properly prepared decommissioning of these things.

    However, those things CAN be solved.

    Sneaky bastard!

    Utilization factor = power generated / (power that could be generated when the resource is available).

    Capacity factor = power generated / (power that could be generated in all hours).

    Solar and wind are typically dispatched as 'must run' being 'use it or lose it', so their utilization factor is near 100%. But that just shows that 'utilization factor' is a statistical lie cooked up to obscure CRAP capacity factors.

  9. Germany by Anonymous Coward · · Score: 2, Insightful

    Germany's effort was intended to get technologies going, and it did just that. You can thank us later. We're still paying for it with every kWh we consume. The guaranteed kWh price paid to solar, biomass, wind and some other renewable electricity producers come out of a surcharge which is currently at ~0.064€ per kWh.

    It is quite unfair and misleading to compare that effort during an early phase of the technology to a future manufacturing ramp up. Nuclear was afforded many more decades to get the technology sorted, but it hasn't, despite massively higher subsidies. Instead nuclear power becomes more expensive all the time, and still defers the majority of the cost into the future, because of an unsolved waste problem. Nuclear fuel sourcing is an environmental and safety nightmare, which just like the waste problem would also need to be scaled up.

    You just need to look at this discussion here on Slashdot to find the never changing arguments: "New nuclear power plants will finally be safe and not produce waste. We'll use thorium and pebble bed reactors." Well, talking about Germany, there was the THT-300 in Hamm-Uentrop, Germany. Was, as the problems with the technology couldn't be solved and it has been dismantled. A research reactor of the same type in Juelich has radioactively contaminated the groundwater and can currently not be dismantled because of the unexpectedly high radioactive contamination. Yeah, let's scale that up to replace fossil fuels. "But AC, we'll use some other new reactor type." Listen to yourselves. After many decades of strong financial and political support for nuclear power, you're still peddling some future as yet undeveloped technology that will finally make nuclear deliver on its promises, promises that were made about every generation of reactors, and have been broken every time. Meanwhile the disasters keep on coming. At the current scale, there is roughly one uncontained meltdown every 30 years. Would you like to multiply that accident count by the scale factor that would be required if we were to replace fossil fuels with nuclear power. Will annual meltdowns be news or will we get bored of that?

    Besides, how do you think scaling up nuclear power will work technically? You do know that nuclear power plants need huge amounts of cooling water, don't you. That's why they're all built next to rivers or oceans. You can't build many more on rivers, because that kills the rivers. At the required scale, you would have to litter the coasts with them. There are no such problems with solar. You can put that stuff everywhere. It works in Germany, which is further north than Quebec.
