CO2-Reduction Potential Through Rational Energy Utilization and Use of Renewable Energy Sources in the Federal Republic of Germany.

摘要

The paper analyses the most important reduction potentials of the private passenger car transportation, of the space heat sectors, of the electricity production sector, of the various industrial sectors and of electricity applications in the industrial, commercial and residential sectors. Additionally the effect of an exploitation of the potential of the renewable energy sector is investigated. Reference is the emission of the energy sector in 1987 of about 770 mill. t CO/sub 2/. The identified technical reduction potential for private passenger car transportation is about 19 mill. t CO/sub 2//a at maximum, for the industry about 20 mill. t CO/sub 2//a, through improvement of the efficiency of electrical appliances in the residential and commercial sector about 34 mill. t CO/sub 2//a and for the space heat technically at least 120 mill. t CO/sub 2//a. The exploitation of the renewable energy sector could reduce the emissions by about 31 mill. t CO/sub 2//a and the maximum reduction through the improvement of efficiency of electricity production is about 20 mill. t CO/sub 2//a without substitution of energy carriers. The identified CO/sub 2/-reduction options in the space heat sector and the majority of the technologies for the utilization of renewable energy sources are not economically viable at present and in the medium term.
