The myth
Anti-nuclear organisations such as WISE Netherlands claim that wind and solar energy make nuclear power redundant. They enthusiastically publish about "record capacity" in wind farms and solar panels, but systematically conceal what that capacity means in practice: thousands of square kilometres of land and sea claimed, mountains of steel, concrete and rare earths, and an industrial landscape that fundamentally transforms the Netherlands.
The question WISE never asks: how much space and material does it actually cost to generate the same amount of electricity?
The answer is painful.
The facts
Borssele vs. wind turbines: the calculation
The Borssele nuclear power plant delivers 486 MW of capacity on a site of approximately 0.1 km². With a capacity factor of 90%, Borssele produces annually:
486 MW × 0.90 × 8,760 hours = 3,832 GWh per year
Take the largest commercially available wind turbine in the world: the GE Haliade-X, 13 MW per unit. At sea, such a turbine achieves a capacity factor of approximately 50%. Annual production per turbine:
13 MW × 0.50 × 8,760 hours = 56.9 GWh per year
To match Borssele, you therefore need:
3,832 / 56.9 = 67 wind turbines
With the required spacing between them (at least 1 km in each direction), those 67 turbines occupy approximately 81 km² of sea surface. That is over 800 times the ground area of the Borssele nuclear power plant.
| Material | Nuclear | Wind (offshore) | Solar (PV) |
|---|---|---|---|
| Steel (tonnes/TWh) | 300 | 1,800 | 1,600 |
| Concrete (tonnes/TWh) | 400 | 2,600 | 3,500 |
| Copper (tonnes/TWh) | 3 | 23 | 85 |
| Rare earths | Minimal | Significant (neodymium) | Significant (silver, indium) |
Nuclear energy uses 5 to 10 times less material per TWh produced than wind or solar. Per unit of usable energy, nuclear is by far the most resource-efficient option.
!Mining: the shadow behind "clean" energy
Ten times less material means ten times less mining. That is not an abstract advantage. The materials for wind and solar energy come from somewhere: The movement that rejects nuclear energy because of uranium mining embraces technologies that require many times more mining — mining that demonstrably causes more human suffering and environmental damage. Nuclear energy largely avoids this. The required amount of uranium is minimal compared with the tonnages of steel, concrete, copper and rare earth metals that wind and solar require. !Lifespan amplifies the difference
A nuclear power plant lasts 60 to 80 years. Borssele operated for 51 years and could technically have continued for decades more. Modern designs are licensed for 60 years with the possibility of extension to 80. By comparison: - A wind turbine lasts 20 to 25 years. - A solar panel lasts 25 to 30 years. Over a period of 80 years, you build 1 nuclear power plant — or 3 to 4 generations of wind turbines and solar panels, including demolition, waste processing and complete rebuilding. Each of those cycles requires thousands of tonnes of steel, concrete and rare materials all over again. Each of those cycles requires transport, installation and grid connection all over again. The cumulative material consumption over the lifespan increases the difference between nuclear and renewables from a factor of 5-10 to a factor of 15 to 40. !Landscape and nature: every square kilometre counts
The Netherlands is one of the most densely populated countries in the world, with 521 inhabitants per km². Available space is scarce and already claimed by housing, agriculture, nature and infrastructure. Onshore wind turbines bring concretely measurable nuisance: - Noise pollution: low-frequency sound audible up to kilometres away. - Shadow flicker: rhythmic light flickering that affects residents. - Bird mortality: tens of thousands of birds and bats per year in the Netherlands, including endangered raptors and seabirds for which — unlike with domestic cats — no natural recovery is possible. - Horizon pollution: turbines of 250+ metres in height dominate every landscape. The Borssele nuclear power plant, by contrast, was remarkably unobtrusive: no cooling tower, no audible noise, no moving parts visible from the public road. A compact industrial building on the Western Scheldt, surrounded by nature. Finland's Olkiluoto 3 illustrates the differences in scale even more sharply. With 1,600 MW of capacity and a capacity factor of over 90%, this single reactor produces more electricity than hundreds of offshore wind turbines. The reactor building — comparable in size to the Oslo Opera House — sits on a fraction of the area that would be needed for an equivalent wind farm. The comparison speaks for itself. !Conclusion
The numbers do not lie. To replace the annual production of one compact nuclear power plant like Borssele, you need 67 of the world's largest wind turbines, spread across 81 km² of sea. You consume 5 to 10 times more steel, concrete and copper. You depend on cobalt from Congo, lithium from Chile and rare earths from the toxic lake plains of Baotou. And every 20 to 25 years, you start all over again. Nuclear energy is not "a" space-saving option. It is 100 to 1,000 times more space-efficient than the alternative, depending on the comparison chosen. It is more material-efficient, more durable in lifespan and kinder to landscape and nature. Anyone who cares about the environment, about scarce resources, about the limited space in the Netherlands, about children in Congolese mines — cannot exclude nuclear energy. WISE Netherlands does the opposite. That is not an environmental movement. That is a belief system with a marketing budget.
