BMW AG’s plan to switch exclusively to green electricity finds it tapping some unusual power sources -- including a South African biomass plant that runs on cow dung and chicken droppings.
BMW’s effort to switch to renewable energy comes as the carmaker is spending billions on a suite of electric vehicles.
Claims of manufacturers making cleaner vehicles are under scrutiny as the amount of power and raw materials involved in production of batteries and electricity sources offsets advantages of emissions-free cars.
In practice, BMW will need to find enough extra power from renewables to supply the equivalent of about 222,000 average homes, based on its annual electricity use of about 1 terrawatt.
To get there, BMW will seek more supply deals with solar energy providers, Jury Witschnig, head of sustainability strategy, said in a separate phone interview Tuesday.
