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.

I'm actually a fan of nuclear and think while it needs to be carefully regulated we could use more of it. But there's no clear reason other sources can't grow at a fast enough pace. We do need to commit to do required items. For example, we need to build a newer smarter grid than the US, which will require some work that's not just engineering. 10 years ago it would have been sensible to say we could not replace fossil fuels without nuclear.

Like wind, it's great in the few places that it's great. Wind and wave power are simply poor ways to harvest solar power. Sure, there are a few places where the energy available is far higher than average, and it makes sense there, but again it doesn't scale.

    Solar is really the only thing that will scale (to 10B people consuming power at current US rates). We might make fission work as a stopgap, but world uranium reserves are actually quite low compared to what would be needed, they'd be exhausted quickly, and there's no evidence we could mine uranium at a rate that would keep up with that scale

    The point of TFA is that we can't build modern solar fast enough. That's a fair point, as it has a long toolchain and is beyond what a third-world nation can manufacture for itself. But there's also solar thermal, which only takes 19th century technology to make work. Right now, solar thermal is just below where it makes sense financially. There are places where modern solar is cheaper per Watt than natural gas, but solar thermal just isn't. But it's not a huge difference, just enough to cross the line into not being worth it.

    tl;dr: We can build all the solar thermal we'd need, and build it fast, and build it locally in emerging nations, if it were really a priority. It's the only non-fossil fuel answer that's true of.

    It's worth pointing out, however, that if we're talking about replacing almost all power generation in just a few decades, orbital solar wins. At current launch costs and energy prices, it already works (it's just less profitable than other things). However, the more we did it, the cheaper it would get. Given we're talking trillions of dollars, just the minimal corporate R&D budget that would inevitably be spent to cut costs would be orders of magnitude higher than all worldwide space-related research funding ever.

    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.
