This quote from our company founder Paul Schwenk has been with us for over 100 years. And the topic has lost none of its topicality. On the contrary. On this page you can find out how diverse the possibilities for saving energy can be and what we can do about it.
With our 24 kWp photovoltaic system on our administration building in Hohenbergstraße, we produce more than 27,000 kWh annually, and with our 115.65 kWp photovoltaic system on our production building in Madertal, we even produce more than 130,000 kWh of electricity. Together with this self-generated and our purchased green electricity, we - and our subsidiaries - are already CO2-neutral in terms of electricity.!
In the period from 01.01.2023 to 31.12.2023, we will purchase green electricity both at the Hohenbergstraße location and at the Madertal location in Haigerloch. These certificates attest to the origin of the electricity from renewable energies, which is produced by certified plant operators. This is checked and confirmed annually by TÜV Rheinland.
Heat pumps may not be the most environmentally friendly form of heating, but they are certainly one of the most environmentally friendly. We have been using them for our production since 2017. This saves us about 90,000 kw/h of gas per year. Depending on the weather and the heating season, this can be significantly more.
Since 2017, we have switched about 85% of the lighting in our administration building in Hohenbergstraße and in our operations building in Madertal to LED. This saves us up to 85% energy compared to conventional lighting. We consistently convert the remaining illuminants after failures or defects.
Admittedly, our fleet has not yet been completely converted to electric vehicles. But we already made a start in 2011. With our first Citroen C-zero. And there are more and more.
Our goal is to achieve complete fleet electrification by 2027.
