The Future of Street Lighting and Trees

Trees and light poles/fixtures are commonplace along most streets in urban environments. While they both provide ample benefits related to quality of life and security, trees are highly regarded for their environmental attributes. However, it is not unusual for the positioning of tree canopies to conflict with safety and required on-street/pedestrian level lighting.
Older style light poles require significant maintenance to replace bulbs, which are often energy inefficient, and keep them clear from existing tree canopy. Efforts are currently underway to retrofit existing light poles with LED’s, incorporating smaller acorn light fixtures and pedestrian up-lighting into tree pits to avoid canopy conflicts. With technological advancement, research is also ongoing to potentially turn trees into light sources using bioluminescent (production of light by a living organism) genes.
How amazing would it be to have a tree lined street lit up at night using only the trees themselves! Bioluminescent animals, ferns and insects already exist in nature. According to a Fast Company Article, researchers are trying to isolate the gene that makes microalgae glow for the purpose of genetically engineering trees into natural streetlights. If successful, this could have a significant impact on future energy savings as their will be less reliance on electricity, use of traditional up-lights, and light poles along streets.

The Many Benefits of Trees


The above diagram shows some fantastic numbers concerning tree benefits in one particular environment. Trees have more value than just the aesthetic and quantifying the value typically results in some fantastic discussion points and often can lead to a renewed interest in tree plantings and proper maintenance. Check out the following article excerpt from the Wildlife Habitat Council to learn more...


Last week I read a fascinating article about urban forestry, which argued that strategically reforesting a 1.5-square-mile area in Houston could help reduce ozone pollution in the city. Using weather data and computer models, researchers estimated that a freshly-grown forest could remove as much as 310 tons of ozone from the atmosphere over the course of 30 years.

This got me thinking about the various merits of urban forests. Did you know that even individual trees provide a multitude of benefits to urban areas? Continue to Full Article
