Energy

The majority of energy in Iceland is generated by hydro-electric power - around 75%

This is less easy to see than the geothermal energy, as much of it is generated in areas of the country that are not much visited by tourists and school groups, far up in the Highlands.

I have actually visited an HEP plant, at Burfell. This harnesses the power of the river Þjórsá

Just under twenty five percent of Iceland's energy comes from geothermal energy.

All energy to stationary locations i.e. buildings is provided from these two sources.

The only fossil fuel usage is in vehicles, and even here electric vehicles are on the rise in ownership.
