> Nuclear power is a zero emissions source of power
Nuclear and offshore wind are equivalent (median: 12 gCO2eq/kWh)

> Alternative renewables (e.g. wind, solar) require fossil fuels to power the electrical grid when they are not able to generate
Overprovision is part of a solution. Storage may tackle part of the challenge ( https://www.nrel.gov/news/features/2020/declining-renewable-costs-drive-focus-on-energy-storage.html https://www.nrel.gov/news/features/2020/declining-renewable-... ).
On a large geographic scale renewables are able to continuously generate enough energy. We know how to transport energy (and nuke plants also need it), and interconnecting grid is considered a win whatever the type of source used (nuclear, wind...).
See https://www.cell.com/one-earth/fulltext/S2590-3322(19)30225-8 https://www.cell.com/one-earth/fulltext/S2590-3322(19)30225-... , which doesn't seem to me more ambitious than hoping to quickly multiply by 10+ the existing nuclear power generation capacity, and hoping that there will be enough practically available combustible for them.
> The amount of energy they output, relative to the energy input to construct
The net outcome is positive.
Moreover renewables don't need fuel, and therefore there is no need to worry about cost/reserves/geopolitical turmoil/terrorist actions/waste.
> amount of land they consume
For solar there are many adequate deserts and unused surfaces. For offshore wind there are huge pertinent areas.
> Nuclear energy is safe, causing fewer deaths and adverse health impacts
There are many ways to consider this. Here is one: https://en.wikipedia.org/wiki/Chernobyl:_Consequences_of_the_Catastrophe_for_People_and_the_Environment https://en.wikipedia.org/wiki/Chernobyl:_Consequences_of_the...
> If it is a dinosaur, then so are the transistors
Transistors sci/tech made and makes huge progress. The nuke promises/dreams (fusion, no-waste...), albeit massively subsidized for decades, are stuck.
- ethanwillis 6y agoSo many workarounds and engineering tasks just to be competitive with the simplicity of Nuclear.
- pfdietz 6y agoNuclear is simple in the same sense mainframe computers are simple. Solar and wind are like blades in a server farm; if one goes down it's no problem. In a nuclear power plant, all the parts (aside from some limited redundancy) damned well better work or the whole system is in jeopardy.
- ncmncm 6y ago> amount of land they consume Many crops benefit from partial shade. So, farms. Likewise cars, so parking lots. Likewise roofs, so warehouses and factories. Likewise irrigation (reduced evaporation), so reservoirs and canals.
- vntok 6y ago> The book was not peer reviewed by the New York Academy of Sciences.[2][9] Five reviews were published in the academic press, with four of them considering the book severely flawed and contradictory, and one praising it while noting some shortcomings.

That book was heavily criticized because it did, in the eyes of critics, not adhere to limiting described effects to such ones commonly and easily attributed to radiation. Fact is, we know surprisingly little about radiation effects. Especially, we clearly do not have a complete theory on the effects of ionizing radiation - especially on children.
