I just checked my plan yesterday, I pay 0.13 Eur, summer and winter. I can commit to my provider for a year and lower it to 0.11, but with slightly higher fixed monthly cost (which is about 50 eur, regardless of consumption). With this prices you less likely to think about the efficiency of fans - it will probably will years to return the cost of fan replacement.
I pay 0.45 Euro for public car charging, returning the cost of installing a charger at my (rented) house will probably take 2 years.
