I’m a renewable bro. I wanna see as much money pumped into as much infrastructure for renewables as possible. I wanna see solar on every building. I wanna see off-shore wind and tidal energy production. I’m keenly following development of clean, efficient, and cost-effective energy storage technologies, and much is being done in this space to support a future switch to full renewable reliance.
That won’t change the fact that we need on-demand energy now and we need to stop using coal and gas as soon as possible. We currently don’t have energy storage at scale. We will, but we don’t. So in the meantime, nuclear is probably the best option to pursue for use over the next couple of decades while we continue to invest in, and implement, renewables.
I will have to strongly disagree here. The timelines are actually the main reason why I would disqualify Nuclear power as a solution to energy, even as a temporary one.
The time from inception to going online for a new Nuclear reactor is in the range of 15-25 years. Of course we could attempt to shorten that, but that would probably mean compromising on safety. So indeed, if we want to stop using fossil fuels asap, building solar, wind, and hydro, which come online in a matter of months (maybe years for hydro), is much faster.
Aggravating this are two further issues: Current Nuclear energy production is non-renewable, and supply problems are already known to occur at current energy production levels. Second, the global construction capacity is limited, probably to around current levels. Even if we do not push for faster construction times, the number of companies and indeed people who have the necessary expertise are already at full capacity, and again, expanding that would probably imply safety problems.
That is to say, currently running Nuclear power plants are save and clean, so by all means keep doing it until renewables take over. But expanding Nuclear power to solve the energy problem is a non-starter for me, due to the timeline and it being non-renewable. And that is before we start talking about the very real dangers of Nuclear power, which are not operational of course, but due to proliferation, war, and governmental or general societal instability (due to say, climate change).
That is a very interesting report, thanks!
Reading through the summary and overview, they address exactly the problem that I've highlighted: how can we build more reactors faster and more economically, without compromising safety? Of course that means that this issue remains unresolved for now, underscoring my point.
They avoid discussing the other risks I've mentioned (stability, war, proliferation) and admit as much, which is fair enough, but I cannot find any comment regarding the availability of fissile material in the supply chain, which I would think is a rather crucial point.
What I take away from this report is that Nuclear power has a place in solving the climate crisis, if we:
All in all, they conclude that sweeping changes are needed (which is always a risk) and disregard crucial present and known risks. Both these points are simply non-issues with solar, wind, and hydro-power.
