The use of thermoelectric materials in the automotive sector to recover and reuse waste heat to produce electricity may lead to improved fuel efficiency, thereby reducing the fuel consumption and greenhouse gas emissions. Various car manufacturers, for instance, Toyota, Honda, Nissan, BMW, Ford and GM, are now focusing on developing automotive TEGs with the target of improving XX% of consumption efficiency. Such factors are expected to increase the demand of thermoelectric materials in the automotive sector during the forecast period.
