> renewables have failed to produce a noticeable change in my part of europe
More electricity in Europe comes from renewables than from either nuclear or fossil, with renewables rapidly approaching 50% market share. Several countries (even the non-hydro-heavy ones) are already showing multi-day periods where renewable electricity exceeds 100% of demand.
If your part of Europe isn't showing a noticeable change, perhaps it might be because your part isn't trying?
Renewables are not suitable for replacing nuclear, coal and other traditional sources of energy due to the fact that you cannot control production.
Yes. On the other hand nuclear is still single biggest source of power in EU, despite german phaseout) There is still not a single country matching french emissions with ren alone if it doesnt have hydro/geothermal
