> In 15 years or so I imagine most countries with sane leadership will be mostly running on renewables & nuclear.
I think it's good to mention that in Europe, 40% of all the electrical energy usage was renewable in 2024 [1]. This number is higher than it was in 2023, and will increase again in 2025 due to many new solar, wind, and battery installations.
In the US, 19% of all the electrical energy was produced by renewables and 20% by nuclear [2].
