Iceland is a geologic freak which allows for geothermal energy generation. Even though it has this, the energy production isn't that great.

AFAIK, Iceland generates about 1336MW total capacity (calculated from CIA world factbook calculations). A modern nuclear power plant generates 1600MW.

A large aluminum smelter uses 1GW of power or even more (that is why they are often next to hydroelectric dams).

Also note that the EU emits about 70% of the Carbon dioxide that the US does.

Calculation:

Production per year kW hours 11710000000

Production per day (kWh) 32082191.78 Production per hour (kW) 1336757.991
