France plans to invest €1.5 billion on infrastructure for the two million electric and hybrid cars it wants on its roads by 2020, according to the ecology minister .

A million battery-charging points will be built by 2015, 90 per cent of them in private homes but also in car parks and at roadside sites, according to a national plan presented by Jean-Louis Borloo.

"No player can take the risk alone, but if all the actors take it at the same time, that works," the minister told reporters as he outlined his government's strategy on helping reduce C02 emissions via cleaner cars. The state and major companies will order 100,000 electric vehicles by 2015.

Nine hundred million euros of the investment money - to be used mostly for infrastructure but also for buying cars and on subsidies to buyers and makers of vehicles - could come from a state loan due to be launched next year.

The state will also participate in the creation of a battery factory at a Renault plant at Flins, west of Paris, by contributing 125 million from its strategic investment fund to the overall cost of €625 million.

The state will give Renault a €150 million loan to build the factory.

French automakers PSA Peugeot Citroen and Renault presented their solutions for tomorrow's cars - electric or hybrid - at the Frankfurt Motor Show.

Renault introduced four electric prototypes in Frankfurt that cover the range from small urban to commercial vehicles.

The firm believes that by 2020 electric cars will make up more than 10 per cent of the market and hopes to present its electric cars by 2011 and have them ready for the market the following year.

Rival PSA Peugeot Citroen equally aims to impress the public with its environment-friendly cars after new company head Philippe Varin, who took over in June, made them one of his priorities.
