Your choices:
1 Electricity; 2 Comfortable indoor climate; 3 Solid biomass
| What is your resource? | What do you want to deliver? | What is the service the customer wants? |
| Biomass (digestible sludge) | District cooling | 2 Comfortable indoor climate |
| Biomass (fermentable sludge) | District heating | Electricity |
| 3 Biomass (solid) | 1 Electricity | Process cooling (< 0 °C) |
| Geothermal | Fuel: Gaseous | Process heat/steam (50 - 150 °C) |
| Sunshine | Fuel: Liquid | Process heat (150 - 1000 °C) |
| Water | Fuel: Solid | Process heat (> 1000 °C) |
| Wind | Local cooling (ind. house) | Transport |
| Residual oils/fats etc | Local heating (ind. house) |
Electricity is the king of energy carriers and should not be used for low-exergy purposes such as indoor climate control.
In case the electricity is produced from solid biomass, and this is the third best option for electricity production after hydroelectric production and wind, then it has most probably been co-produced with district heating and with district cooling. Provided the building to be heated/cooled is within reach of the district heating/cooling distribution systems, then these energy carriers should be used for climate control and not electricity.
