The work subsidised by the OeNB Anniversary Fund provides an extensive overview of the current situation and likely developments in electrical and hybrid vehicles. The ecological effects of the various components – drive mechanism, battery, body – and their interactions were studied in the light of different energy supply scenarios.
The clear summary permits concrete models to be categorised and their ecological impact assessed. This will help funding agencies and policy-makers to reach decisions. The study is rounded off by a market survey of electrical vehicles currently available.
According to the study, the energy consumption of electrical vehicles should not be an issue: even with a 10% market share (substitution) the additional power consumption in Austria would only be 1.8%. However, the total energy consumption and emissions depend on the power generation scenarios on which the calculation is based. If the power is generated as in most European OECD countries, electrical vehicles would reduce carbon dioxide emissions by 40% compared with vehicles with internal combustion engines; hydrocarbon and carbon monoxide emissions would disappear almost completely. There would be a slight improvement in nitrogen oxide emissions but none with respect to sulphur dioxide and particles. In the case of hydroelectric power generation, as in Austria, the advantages would be practically twice as great.
