Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Excellent summary Dodo and insightful comments by Jerome and Skenna Kowa.

I particularly appreciate your use of TWh of generation as the units most appropriate for describing the contribution of renewables.

I've found that for system-wide contributions, wind will deliver about 2,000 kWh/kW/yr of installed capacity. Thus, 10,000 MW will add 20 TWh/yr of generation.

Similarly, solar PV contributes about 1,000 kWh/kWDC/yr of installed DC capacity across Europe. Germany's total PV capacity of ~8,000 MW should deliver ~8 TWh/yr or ~1.5% of total supply.

Yep, but with significant geographical variation even at country level: Britain should be closer to 3000 kWh/yr/kW, New Zealand even around 4000 kWh/yr/kW.
