Energy-aware rewinding strategies

- Einsparpotential :
Failures in the electrical windings of a motor are common for motor failures. Especially for larger machines, rewinding is a strategy to restore the motor in a relatively cheap and quick manner. Yet, rewinding may permanently affect the losses in a motor. If rewinding is necessary, it should be verified whether acquiring a new motor might be a more energy-efficient and cost-effective alternative in the long run.
Use of highly-efficient uninterruptible power supplies
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: ICT
- Implementierungsaufwand :
- Einsparpotential :
An uninterruptible power supply (UPS) ensures that IT-equipment is powered by a battery even in case of an abrupt failure of power. Due to the double conversion from AC power from the grid to the DC power in the battery and back to AC power for devices, an UPS often has losses of up to ten percent. Highly efficient UPSs can cut these losses by about half or more.
Switching off IT equipment
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: ICT
- Implementierungsaufwand :
- Einsparpotential :
During longer breaks or meetings it is reasonable to switch off monitors since they are not needed when they are not used. Manually operated switchable sockets can also help to completely shut off local IT equipment after office hours, thereby reducing energy demand.
Optimization of logistics
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: Logistics
- Implementierungsaufwand :
- Einsparpotential :
Fuel consumption depends among others on the travel distance and on the amount of transported goods. Optimizing routes and using tour planning software can help to reduce travelling times and to make best use of available transportation capacities.
Vehicle optimization
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: Logistics
- Implementierungsaufwand :
- Einsparpotential :
Making on-board support systems such as cruise control or consumption monitoring systems available can support drivers in driving more economically and energy-efficient. Adding spoiler can also decrease the wind resistance and thus consumption of vehicles.
Driver training
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: Logistics
- Implementierungsaufwand :
- Einsparpotential :
Individual driving styles and the use of heating or air conditioning can substantially affect the fuel demand of vehicles. Specific training courses can help drivers to recognize inefficient driving styles, to better adapt the use of heating and cooling and to thus learn how to reduce fuel consumption on their job.
Tyre optimization
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: Logistics
- Implementierungsaufwand :
- Einsparpotential :
Well-inflated tyres and the use of low consumption tyres can help to reduce friction and thus allows to save energy.
Consideration of alternate means of transport
- Kategorie: Cross-Cutting
- Bereich: Processes
- Unterbereich: Logistics
- Implementierungsaufwand :
- Einsparpotential :
Trucks have a higher specific energy consumption than trains or ships. Therefore, it is advisable to check for economically viable alternative means of transportation to reduce energy consumption.
