Berlin, Aug 3 (TIWN) German rail operator Deutsche Bahn wants to motivate its employees to save energy at the workplace with a one-off bonus of at least 100 euros ($102).

"We want all 200,000 employees in Germany to become active, to pull all the smaller and larger levers in order to end up with a significant amount of savings," dpa news agency quoted Chief Human Resources Officer Martin Seiler as saying here on Tuesday.

It is about issues such as lighting, heating, the use of air-conditioning, refuelling, "or maybe using the stairs instead of the lift," Seiler said.

If the company reaches an unspecified energy-saving target, the bonus could be increased to 150 euros for all employees.

Seiler did not say how big the savings had to be or how they would be measured.

In view of the impending supply bottlenecks for gas, Seiler referred to other measures with which the company wants to save energy.

These include the replacement of fossil heating systems with alternative heating systems and the removal of the exterior lighting of its headquarters.

With an annual consumption of around 10 terawatt hours, the railway is the largest electricity consumer in Germany.

According to its latest annual report, natural gas accounted for more than 6 per cent of the electricity mix last year. More than 20% was generated from lignite and hard coal.

The share of renewable energies was around 62 per cent.
