> This is an important consideration when looking at the cost of scaling nuclear power as it gets far more expensive the lower the utilization. You can get to around 40% across an electric grid such as Europe or an island, but scaling past that needs truly massive subsidies.

This is why diversified solutions are best. You get ~40% from nuclear and the same from solar and you're 80% carbon-free. Even using natural gas for the last 20% would put you well ahead of most countries as it is, and as storage or other alternatives improve you can move even that to solar+storage or whatever alternatives.

The linked page tracks both - production and consumption.

For example, at the moment, Germany produces at 415g/kWh but consumes at 382g/kWh, mostly thanks to 3 GW import from France and 2.7 GW import from Switzerland.

The map shows both production and consumption, but it only tracks carbon by production nationwide.

PS: It’s not uncommon to see a country export and import electricity at the same time. In that context using nationwide numbers is clearly missing important details.
