| What is your resource? | What do you want to deliver? | What is the service the customer wants? |
| Biomass (digestible sludge) | District cooling | Comfortable indoor climate |
| Biomass (fermentable sludge) | District heating | 2 Electricity |
| 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) |
| 3 Wind | Local cooling (ind. house) | Transport |
| Residual oils/fats etc | Local heating (ind. house) |
Wind power production is the second most efficient way to produce electricity – surpassed only by hydroelectricity.
Whether one likes it or not, it is a fact that wind farms do have a major visual impact and the planning of a large-scale wind mill or wind farm must take place in close connection with those living in the area so as to avoid social conflicts.
During the construction phase, the site must be accessible for heavy-duty transports, but this holds true also during the life-time of the farm. Maintenance and breakages may well require that the turbine itself or the turbine head (the nacelle) is dismounted from the tower top and brought down to ground level, though this is not the case for normal maintenance.
Since wind power is an intermittent source of energy, the grid operator may well raise arguments against a larger wind-farm installations because of technical reasons and the risk for flickering.
