Marine Cornelis is an energy policy advisor and the founder of Next Energy Consumer. She advises institutions, regulators, cities, and energy actors on the politics, risks, and public expectations that shape whether the energy transition actually holds.

For more than fifteen years, she has worked at the intersection of EU energy policy, consumer protection, and social justice, advising European institutions including the European Commission, executive agencies, and the Joint Research Centre, notably in the context of the New European Bauhaus.

She is the author of the first-ever European Commission report on summer energy poverty, which helped reframe EU debates by linking heat, housing, and vulnerability beyond winter heating. Her work consistently interrogates how market design, grid costs, pricing models, and digitalisation play out for households in practice.

Marine is known in EU policy circles for bringing a sharp, politically literate, and human lens to energy debates. Organisations turn to her to challenge comfortable assumptions, anticipate backlash risks, and design policies and market narratives that people can actually live with.
