Increasing electricity consumption has proved to be a problem as the use of electricity creates a need for fuel that affects the environment in devastating way. A company named Glowee in Paris, France is working to reduce the electricity consumption. The company is developing a way to brighten cities at night using glow-in-the-dark bacteria instead of electric light bulbs. Glowee developed lights made of small, see through cases that contain a type of non-harmful marine microbe known as Alivibrio fischeri. This microbe is normally found living inside light-emitting organs on the skin of an underwater species called the Hawaiian bobtail squid.
The light cases contain a nutrient-rich gel for the microbes to feed on, and they are now able to stay lit for three days at a time. Currently the company is working to keep the lights on for a month or longer. The company’s goal is to try to reduce the 19 percent of electricity consumption used to produce light as well as reduce the light pollution from the light of human-made sources that obscures objects in the night sky and which can affect animals’ natural cycles. Although the lights are not very bright yet and are not able to stay on for too long, the company is still working on the product, and hopes to illuminate sidewalks, storefronts, and signs all by 2017.
