25 Economical Background in Germany - Income until 2000: about 50% by tipping fee for waste, about 50% by selling electricity to public grid - Income until 2004: about 25% by tipping fee for waste, about 75% by selling electricity to public grid - Income now: 100% by selling electricity to public grid (energy crops and manure); about 25% by tipping fee for waste, about 75% by selling electricity to public grid (waste digestion) all the time: low interest rates for investment in renewable energies
