Solar power lights for the high street
Redland Shire Council, Australia, is using Orion solar bollard as part of two schemes on the highway.
The bollards use solar energy to generate lighting for pedestrian walkways. Not only are they good for the environment, they are also quicker and cheaper to install, as they require no digging of ducting trenches into the ground.
While this solution might not be adequate in countries with low sunlight, more and more companies provide such devices.
Solion is one of them, and is based in the UK. Their website does not give details of who their clients are but there is a picture of a curved sollar cell for street furniture attached to the top of a London bus stop flag. As a londoner, i cannot say i have noticed them so far but i will keep my eyes open
