The good news: A Dennerle Nano Cube or Nano Tank can be operated very energy-efficiently. If shrimp, snails or dwarf crayfish are kept, the filter and light included in the set are sufficient as technical equipment. An additional heater is not necessary, as these animals do very well with the usual room temperature of 20 – 22 °C.
For a Nano Cube Complete Soil 30 L, the cost of electricity is only 0.04 € per day. And even a large Nano Tank Plant Pro 70 L only requires electricity for 0.14 € per day.

Overview energy consumption of filter, light & heater
If you want to keep tropical fish, a water temperature of 24 – 25 °C is needed. The electricity costs for heating the water are then added. But these are also manageable for nano aquaria:
