Central/Western European Countries Heavily Reliant on Hydropower

The following Central/Western European nations generate a majority or large share of electricity from hydropower:

1. Switzerland

• ~55–60% of electricity from hydro
• Alpine topography + high precipitation = ideal conditions
• Long history: first large plants early 1900s; pumped storage expands flexibility

2. Austria

• ~55–65% from hydro (run-of-river + reservoir + pumped storage)
• Alpine geography; strong policy support for renewables
• Verbund, the main utility, is a hydro leader

3. Norway (Nordic, often grouped in "Western Europe" energy contexts)

• ~90–95% from hydro — world leader
• Massive reservoir capacity; exports power to EU via interconnectors
• Not EU, but integrated in European energy market

Honorable Mentions

• France: ~10–12% hydro (but ~70% nuclear)
• Italy: ~15–18% hydro (Alpine north)
• Spain: ~10–15% hydro (Pyrenees, Cantabrians)
• Germany: ~3–4% hydro (limited geography)

Switzerland and Austria are the core Central European hydro powers; Norway is the undisputed European leader overall.
