5 ways to reduce light pollution in cities

If you live in a city like most people, you probably can’t see the Milky Way at night. Maybe you’ve never even spotted it at all. The night sky in most cities is a pink glow with only the moon, bright stars, and passing airplanes visible.

Light pollution is the form of pollution that most people have forgotten. Light pollution occurs when extra light from large cities filters into the night sky. It causes problems such as adding to carbon emissions, interfering with animal migration, and blocking nighttime views. While brightened skies may not be as important as environmental pollution, light pollution still hurts wildlife, energy resources, and human health. Here are 5 ways light pollution can be reduced.

Light Pollution Solutions #1: Smart Energy Management System

You’re in bed but you can’t sleep, because the street lights outside is too bright. Imagine if you could send a text and have the light turned off a few moments later.

This technology may soon be possible, thanks to smart energy management systems. This lighting solution would allow you to control one or many streetlights remotely. It works for many types of LED street lights, solar street lights and even the all in one solar street lights.

The system gives you access to live, current information, so the right amount of light is given where and when needed. If it is not needed, the light can be turned off, dimmed, or placed on a schedule. This solution uses the lighting system already in place, turning it into the system of the future.

The detailed system reduces energy loss and allows the lighting network to run as smoothly as possible. Since lights are controlled wirelessly from a central system, they can be adjusted for any reason. Some examples are changes in weather, circumstances, or a person’s need.

“If there is a football match, the lights in the area can be told to come on when everyone is leaving and dimmed after they have gone. The technology allows you to adapt to circumstance.”

In the past, such systems were only made for individual houses and businesses and were expensive. They could not be used for street lamps until now, since costs have been lowered. The systems can be used with existing lamps, so they only need to be updated and not replaced.

Light Pollution Solutions #2: Start with ‘A Big Switch-Off’

Light Pollution Solutions #2: Start with ‘A Big Switch-Off’

The cheapest, most obvious, and most effective light pollution solution is to start turning things off.

There is a time and place for outdoor lighting—during after-dark activities, for instance. But many of us burn porch and spot lighting because it gives us a sense of security.

There’s little data to support the idea that outdoor lighting reduces crime. Turn on the LED or solar streetlights only when you need them, or use portable lighting. Turn them off when you don’t need them.
