Volkswagen trusted non-renewable power sources for round 80 p.c of its wants, whereas for BMW the determine was over 60 p.c, based on 2021 Carbon Disclosure Undertaking (CDP) knowledge, primarily based on 2020 figures supplied by the businesses.
Reliance on fossil fuels
Over half of the automakers’ power consumption was from fossil fuels, with the most important chunk from pure fuel, based on the CDP knowledge, the world’s largest repository of environmental knowledge.
Whereas automobile corporations more and more have their very own renewable energy mills on-site, these lined a miniscule quantity of their international power urge for food – round 1 p.c for Volkswagen and even much less for Mercedes-Benz and BMW, based on the information.
Mercedes’ most energy-efficient manufacturing facility in Sindelfingen, close to Stuttgart, sources 30 p.c of its power by way of photo voltaic panels on the roof, the corporate has stated.
The automaker stated in early April that renewables lined 45 p.c to 50 p.c of its power wants at current, and that it goals for 15 p.c to be met by way of on-site renewable energy mills by 2030.
BMW’s plant in Leipzig, Germany, generates 20 p.c of the power it wants for manufacturing from 4 on-site wind mills. The manufacturing facility builds full-electric and combustion engine vehicles together with the i3 full-electric hatchback and the two Sequence Gran Coupe.
BMW declined to say what quantity of its whole power consumption throughout Germany is generated from renewable sources on- or off-site, however a spokesperson stated it was not sufficient to cowl the automaker’s wants if the fuel is switched off.
Tesla photo voltaic panels
Tesla’s new plant in Gruenheide close to Berlin has photo voltaic panels on the roof, however a spokesperson didn’t reply to a request for touch upon the panels’ capability or whether or not the plant has another renewable power sources.
“It is essential corporations are open in regards to the electrical energy they eat,” stated Silke Mooldijk, an power researcher at environmental think-tank New Local weather Institute, which displays the power combine and carbon footprint of main corporations.
“They’ve an essential position in reminding individuals that there is nonetheless lots of work to do,” Mooldijk added.
Information from Germany’s atmosphere company confirmed half the nation’s industrial power consumption in 2020 got here from fuel or coal, a lot of it equipped by Russia.
Bosch, the world’s largest auto provider, informed Reuters it meets solely round 1 p.c of its power wants worldwide by way of on-site manufacturing of renewable power, with the most important chunk sourced from photo voltaic panels in India. It goals to boost this to five p.c by 2030, a spokesperson stated.
New funding lags
BMW stated in its responses to the CDP questionnaire that 39.5 p.c of its international power consumption was from renewable sources, primarily based totally on electrical energy it bought on the open market.
However greater than half of the renewable power bought by BMW is purchased within the type of so-called “unbundled power certificates” offered by renewable suppliers. This permits BMW to sign demand for renewable power to the market which ought to immediate funding in additional capability — however it doesn’t imply renewable power is definitely flowing into the carmaker’s vegetation.
Moreover, an oversupply of certificates from decades-old European hydropower vegetation means their sale doesn’t essentially spur new funding, power researcher Christoph Riechmann of consultancy Frontier Economics stated.
“The entire thing can be much less problematic if buying and selling in inexperienced power certificates wasn’t like a revolving change… this drawback cannot be averted except there may be transparency for all clients on the origin of the electrical energy they purchase, for them to make a aware alternative,” Riechmann stated.
World’s first CO2-free car plant
BMW stated it was working to incentivize the development of latest vegetation through direct contracts with suppliers, and looking out into the way it may improve the proportion of power sourced on-site.
The automaker stated its new manufacturing facility in Debrecen, Hungary, the place manufacturing of the New Class all-electric automobile will launch in 2025, would be the world’s first automotive plant to dispense fully with fossil power sources in its manufacturing processes.
A big share of the plant’s electrical energy might be generated straight on website. The rest might be lined by 100% renewables, the overwhelming majority of which is able to come from regional sources, BMW stated in an announcement.
