The article discusses the emergence of electric vehicles (EVs) as the future generation of transport in South Africa. It announces the availability of the new EV incentives suggesting that both the manufacturers and the government witness an industry shift. It is expected that hybrid vehicles will strong growth in the industry backed by various governments' environmental legislation. It also reveals the issues of depreciation and resale encountered by the industry.
In view of the heavy investments by governments and the private sector in industrialised countries in electric vehicle development an attempt is made to assess the extent to which these efforts will pay off, particularly in the us market. The impacts of two types of vehicles are examined: electric vehicles entirely dependent on energy stored in batteries, and hybrid vehicles equipped with both an electric motor and a small auxiliary internal combustion engine. Electric vehicles will continue to be serially produced at costs higher than comparable internal combustion engined cars until mass production can be justified by high sales. The US Department of Energy electric and hybrid vehicle demonstration programme is intended to help the electric vehicle break out of this vicious circle. If the US Department of Energy's demonstration programme ends successfullythe sri scenario depicts a slow but steady growth of the electric vehicle market.
