Table of Contents arrow down

We have come a long way in street lighting. Now, it’s time we consider the impact it has on nocturnal wildlife. We need to evaluate whether solar streetlights are a better option compared to traditional ones. As sustainability is a global focus, we must think about how our choices affect the environment and public safety. EnGoPlanet will explore the impact of solar lighting on wildlife and the importance of sustainable street lighting, as well as eco-friendly and energy-efficient lighting solutions.

Solar Lighting vs Traditional Lighting

Solar street lights work by using energy from the sun to produce electricity, which is then used to power the lights. This makes the solar power street light price lower. These lighting solutions do not rely on non-renewable resources or need a grid connection. In contrast, traditional street lights are powered by non-renewable energy sources like fossil fuels, using a grid-powered system. They have a bigger environmental impact. They emit a bright, often harsh light that spreads widely across the environment. Common types of traditional street lights include high-pressure sodium lamps and metal halide lamps.

Let’s explore the impact of solar lighting on wildlife by comparing it to traditional lighting regarding the following aspects:

  1. Carbon footprint
  2. Light intensity
  3. Light pollution

Carbon Footprint

A carbon footprint is a way of measuring how much greenhouse gas, like CO2, is put into the air because of human activities. Every single thing we do, from how we travel to what we eat, has an impact on our carbon footprint. Even streetlights can play a role in shaping the environment.

Traditional streetlights are often powered by nonrenewable sources, which contribute to carbon emissions. In 2021, U.S. electric power plants alone released about 1.65 billion metric tons of CO2. On the other hand, solar street lights have a much smaller carbon footprint because they use clean energy and are designed to be sustainable. This is significant because ecosystems need to withstand and adapt to changes in the environment caused by climate change. From the comparison between solar and traditional lighting carbon footprint, we can see that solar powered lighting is a better choice. It helps wildlife maintain their natural behaviors, such as migration and reproduction, without being affected by excessive carbon emissions.

Light Intensity

Municipal solar street lights are a good choice for urban areas and wildlife because they emit a gentle and controlled light, which is less intrusive and more focused. This type of lighting preserves darkness, which is important for nocturnal animals to navigate their surroundings without any disruption from overpowering lights.

In contrast, traditional street lights have a higher brightness intensity, contributing significantly to light pollution. They create an artificial glow, which can harm nocturnal wildlife by disrupting their natural behaviors, such as navigation, feeding, and mating. Bright street lights can also cause difficulties for birds, insects, and mammals, leading to widespread light dispersion that makes natural darkness scarce.

Light Pollution

Solar street lights are energy-efficient lighting solutions that reduce light pollution as they represent energy-efficient lighting. This is another example of the positive impact of solar lighting on wildlife. Solar lights use less intense illumination, which helps to protect the environment from excessive light.

By using residential solar street lights, sustainable communities can create urban environments that respect the need for darkness at night. Lowering the intensity of light benefits stargazers and urban dwellers and helps protect nocturnal animals. The focused beams of solar lights are a more considerate lighting solution that works with the natural rhythms of the nocturnal ecosystem.

On the other hand, traditional street lights increase light pollution. They emit too much brightness, which spreads all over the place. This kind of light transforms the natural environment at night and can harm wildlife. It also makes it hard to see the stars and other celestial bodies. Traditional street lights can disrupt the natural habitat of nocturnal animals by altering their navigation and mating habits. This may make it difficult for them to adapt to urban environments.

Examples of the Impact of Solar Lighting on Wildlife

Let’s take a look at specific examples that show us the impact of solar lighting on wildlife, such as:

  1. Birds
  2. Insects
  3. Amphibians and reptiles
  4. Bats
  5. Sea turtles
  6. Fish
  7. Wildlife in urban parks


Birds face a serious threat during their nightly migration due to bright, traditional lighting. This type of lighting increases the risk of disorientation, collisions, and navigational issues, which can negatively impact the migratory patterns of birds and their well-being.

To solve this, solar lighting offers a safer environment for birds during their journeys. Its low intensity provides a subdued glow that significantly reduces the risk of disorientation, helping with more effective navigation.


The bright lights attract insects, which disrupts their natural behavior and can upset the balance of nature. However, solar lighting has a different approach. By using lower intensity lights, they don’t attract insects as much and allow them to maintain their natural behavior. This helps preserve important ecological roles like pollination. By using solar lighting, we can help balance the ecosystem and reduce the harm caused to insects.

Amphibians and Reptiles

Traditional lighting disrupts the natural behaviors of amphibians and reptiles. This includes feeding habits and mating rituals. It affects their ecological roles. Transitioning to solar lighting is a better solution to minimize interference in their essential activities and promote ecological harmony. Solar lighting has a softer glow that creates an environment that is less disruptive for these creatures.


Traditional lighting can be a problem for bats and their nocturnal foraging. The high intensity of the light can interfere with bats’ echolocation and hunting abilities. This can impact their crucial role in controlling insect populations.

However, a shift to solar lighting, which has a lower intensity, can make a big difference. For instance, a highway solar street light emits less brightness. Therefore, bats face fewer challenges during foraging. This helps preserve their natural behaviors and supports their role in maintaining ecological balance by controlling insect populations.

Sea Turtles

Sea turtle hatchlings face significant challenges when exposed to traditional shore lighting. The artificial brightness confuses the hatchlings, leading them away from the ocean and increasing their risk of danger.

Fortunately, solar lighting offers a solution. The lower intensity of solar lighting mimics the natural light cues, helping hatchlings reach the ocean safely and increasing their chances of survival.


When using traditional lighting in aquatic environments, the high intensity of the light and its reflection in water can create problems for fish. This can disrupt their spawning activities and alter their behavior, which can negatively impact the overall health of aquatic ecosystems.

However, using solar lighting can make a big difference. By controlling and directing the light, solar lighting can reduce the reflection of light in water. This is another instance of the positive impact of solar lighting on wildlife. It helps to maintain natural conditions for fish. This shift to solar lighting is an important choice for promoting healthier aquatic ecosystems and ensuring the sustainability of fish populations.

Wildlife in Urban Parks

Urban park wildlife is affected by traditional high-intensity lighting in the same way as most other animals. It alters their natural activity patterns. Squirrels and birds are essential components of urban green spaces, but constant brightness disturbs their feeding and nesting behaviors.

Using park solar lighting with lower intensity provides a gentler illumination that allows wildlife to maintain their natural activity patterns. This shift promotes a more harmonious coexistence in urban green spaces that is beneficial to both humans and wildlife and helps support healthier and thriving wildlife populations.

Solar Powered Lighting Preserves Wildlife

In planning our cities, let’s keep in mind our nighttime neighbors – the wildlife that shares the urban areas with us. The kind of public lighting we choose matters. Bright, traditional ones can affect the lives of birds, bugs, and other creatures that come out after dark. Choosing solar lights, such as commercial solar pole lights, is a simple switch to green energy that makes a big difference. Urban planners, builders, and all of us in the community should be aware of the positive impact of solar lighting on wildlife and making our cities comfortable for us and for the animals that share our space. We should strive to use sustainable technology and light our cities responsibly.
