Renewable energy

Renewable energy carriers play a major role in climate change mitigation and the conservation of resources. We analyse their environmental impacts, identify realisable potentials and supervise pilot projects. We provide consulting services for ministries and public authorities, and optimise policy instruments for the promotion of sun, wind, water, and biomass.
