Future demand

The future energy demand is derived from the recent energy demand. In addition, the following effects can be considered:
- Efficiency changes when switching from fuel to electric drive
- Elimination of heat loss by replacing technically outdated heating systems
- Reduction of demand by means of direct use of wind or solar energy (like Skysails vessel, airships with solar cells, solar architecture in house construction)
- Reduce the need for low-temperature heat through thermal insulation
- Sufficiency or increased demands
