In 2020, industry within the area of the old Länder will only need 55% of the fuel demand of 1990 (based on net production). This leads to an almost constant absolute fuel demand (96% based on 1990) due to the expected economic growth. In combination with the probable substitution of energy sources, the CO2 emissions will fall by 15% compared to 1990. In contrast, the absolute electricity demand will increase by 35%, whereas specific energy consumption will fall by over 20%. Additional fuel conservation potentials of up to almost 25% seem possible with strongly increasing marginal costs of up to 50 DM/GJ. As well as electricity conservation potentials of almost 15% with marginal costs of up to 100 DM/GJ. In the new Länder, in 2020, industry will only require about 70% of present fuel consumption and will emit only 45% of 1990 CO2 emissions. In contrast, electricity demand will increase to above 80%. Additional fuel conservation potentials of 15% and electricity savings of about 10% sho uld allow similar marginal costs as in the old Länder. The final energy demand of the small consumers sector in the old Länder in 2020 will be almost as high as in 1990, while CO2 emissions should have fallen by 15%. Additional potentials for energy conservation of about 20% and substitution of energy sources could halve the CO2 emissions of this sector.
