On behalf of the Baden-Württemberg Ministry of Environment, Ecologic Institute analyzes various fundamental questions regarding the marketing and promotion of renewable energies. In an interdisciplinary research team led by consentec, Ecologic Institute is responsible for energy law-related issues. Among the central topics are reform approaches for the Renewable Energy Sources Act, the regional steering of the development of renewable energy sources, the marketing of green electricity and the regulation on self-consumption of solar energy.
