The Guardian on the electric car in Britain. Plug in hybrids and fully electric cars would be a great answer for towns, but the lack of off road parking where they can be charged is holding them back.
I’ve seen illuminated road signs and various other roadside devices that are solar and/ or wind powered. How hard would it be to create parking meters which were actually charging points, with solar panels on the top, batteries stored in the ground under them and a trickle feed from the mains for winter and overcast days? Electric car owners could pay a minimal amount to charge or be given pass keys, non-electric drivers would pay normal rates or be barred from them altogether. Another possibility would be placing windmills atop multi storey car parks and reserving a few spaces on the top level for replenishing electric vehicles.
