Saving electricity

Saving electricity

Energy flows and consumption are analyzed systematically at STIHL; savings potential is calculated and possibilities are examined for using energy more efficiently. In this way, we are acting in conformance with the ISO 50001 energy-management system.

In production, for example, the performance of each STIHL power tool is tested after assembly with the engine under full load, and its fuel consumption is measured. So that the energy applied in these tests is not wasted, the braking energy is converted into electricity and fed back into the network. For each machine, about 200 watt-hours are returned to the electricity network. This is the equivalent of five 40-watt light bulbs burning for one hour.

AT STHL Tirol a new photovoltaic system has allowed the company in Langkampfen to save 14 metric tons of CO2 a year. For this, Austria's Federal Ministry for Transport, Innovation and Technology (BMVIT) has named STIHL Tirol one of 25 companies in Austria to receive the distinction of being "klimaaktiv," or "climate active," for its commitment to energy efficiency.

The reduction of energy consumption is prioritized also at the STIHL plant in Wiechs am Randen. The factory hall's ventilation system has been fitted with a highly efficient heat-recovery system: 90 percent of the heat energy contained in the hall's waste air can be recovered, equivalent to 800,000 kilowatt-hours each year. This results in a substantial reduction in CO2 emissions of approximately 46 tons per annum.
