One year on from their introduction, a fleet of 18 electric Renaults has made big inroads into the Eden Project’s running costs.

Eden took delivery of the fleet a year ago and is seeing many advantages, including financial savings. The vehicles are not subject to road tax and have cost Eden only 4.4p per mile to run (equivalent diesel vehicles would cost more than 11p per mile).

Electric vehicles also have the advantage of not having any tailpipe emissions so are able to work inside Eden’s Biomes where diesel or petrol vehicles can’t because of pollution concerns.

Eden’s vehicles include the compact hatchback ZOE, Kangoo Van Z.E. and a brightly-coloured fleet of Twizy quadricycles.
