The main alternative to reduce the pollution derived from fossil fuels is to replace such fuels by means of renewable energy sources. The applied analysis through life cycle assess-ment showed that a vehicle powered by renewable energy sources, purely electric, battery driven, has considerable environmental and economic advantages over hybrid and/or conventional vehicles.In the present market conditions, the overall performance of an ICEV in economic terms is better than that of the RAMseS. Only when fuel prices reach 1.8 € L-1, RAMseS obtains paritywith the conventional system. The RAMSES investment can be recovered only if the net energy prices go up to above 0.35 € kWh-1 and 1.3 € kWh-1 respectively for RAMseS without EV and for RAMseS with the EV. Finally, the analysis shows that RAMseS payback period is maximum 9 years if net energy price does not get lower than 0.35 € kWh-1.
