Swedish energy company Vattenfall and the Volvo Car Corporation are launching an industrial joint venture partnership to introduce Plug-in hybrids on the market in 2012. The ground-breaking technology will considerably lower the environmental impact from traffic. In addition, owning a Plug-in hybrid vehicle will be convenient since the car can be charged from a regular household wall socket at home (costing only 3 Euro per 100km) and fuel costs are significantly lower, using only 2 litres per 100 km. The battery takes about five hours to charge from a standard wall socket, and the battery is also charged every time the car’s brakes are applied. Volvo Cars will manufacture the cars and Vattenfall will develop charging systems and supply the cars with electricity.
