  • when a lighting technology (e.g. LED) uses less energy than existing bulbs (e.g. incandescent or CFL) to produce the same amount of light.
  • when installing an exhaust gas boiler can save many m3 of gas which can be used for expanding production.
  • when optimizing energy use to produce more with the same or less energy.
