The TÜV SÜD – EE01 ecolabel encourages suppliers to diversify their technological mix. To this end, they must respect a minimum distribution of different energy sources from the first year of accounting. This includes:
Hydroelectric (less than 2 MW): 10%
Wind: 7.5%
Solar, geothermal, biomass: 5%
Biogas/biomethane: 3%
All installations commissioned after January 1, 2000, are eligible, making it easier to achieve a balanced technological mix.
