These are our new solar wind turbine powered street lighting

Haven't seen one of those, but I vividly remember these:

When did trolley buses stop? Environmentally friendly and cheap, they finally succumbed to car ownership and fossil fuel on 11 January 1970. Yet half a century later, local councils now see electric public transport as an answer to congestion and air pollution.

In my area trolley buses completely stopped in 1960 ...nothing whatsoever to do with wind powered street lamps tho'
 

Here they opted for LED smart street lights.

When the entire system is converted to LED, it will save over 10.8 million kWh hours per year and over $3 million in annual operating costs.

The smart lights can also notify the city of snow and ice, problems with traffic flow, control the intensity of the light as conditions change, and report equipment malfunctions.

IMO they are a solution in search of a problem, but the investment and changeover have created a few jobs.

We've had those for some years now...LED has had some bad press in recent years... so I dunno if that's the reason they're moving towards these new wind turbine..street lights

Recent reports that grabbed the headlines include one published by Public Health England into the photobiological impact of LED lighting. This concluded that there was a possibility that blue light emitted from LED light sources had the potential to cause disruption to melatonin production affecting our circadian rhythm, sleep patterns and therefore health. What some articles based on the report failed to mention was that as LED street lighting had a thin film applied directly to the LED chip, using these light sources, the report states, there was no evidence to support any human photobiological disbenefits.


A more recent report evaluating the association between artificial light-at-night exposure and breast and prostate cancer risk in Spain has caused much consternation and associated an increase in these cancers with artificial light at night. For outdoor lighting, the report used digital photographs from the European Space Agency NightPod system, using a spatial resolution of about 30m. Using photograph pixel data, calculations were made to ascertain the amount of light within a specific range known to cause melatonin suppression. It is melatonin that affects our circadian rhythm and can affect hormone production. The report suggests these hormone changes are responsible for an increase in the hormone based prostate and breast cancers. However, this study only measured upward light. LED street lighting emits little upward light, the majority is directed to the area it is needed. The study also fails to identify the sources of light; domestic, recreational, security or commercial. The inference seems to have been that it is all street lighting.


Another area of bad press for LED street lighting has been glare and possible eye damage. The requirements and limits associated with the photobiological safety of lamps and lamp systems is contained in BS EN 62471. The Standard is concerned with the short wavelength elements (blue and UV light content) of light sources. Most street light sources are safe when people are at a ‘normal’ distance from it.
