Industrial employees with specialised knowledge and well-rounded fundamental skills are indispensable for realising the full potential of overall sustainable production. Energy management competencies are interdisciplinary, meaning that various training profiles, such as that of the classic electronics or electrical engineer, are being enhanced to include sustainability-related skills. In addition to these broad training requirements for green issues, there is also an increasingly diverse range of specific job profiles related to energy efficiency on the labour market. These include energy engineers and energy auditors, sustainability managers, greenhouse gas report auditors and carbon capture installers, to name just a few. Well-trained energy efficiency and environmental experts have excellent career opportunities, and this trend is rising.
