IMPACT OF LIGHT POLLUTION ON ENERGY EFFICIENCY

This paper examines the impact of light pollution on energy efficiency with a focus on the European context. Light pollution, caused by excessive and mismanaged artificial lighting, contributes not only to ecological degradation but also to unnecessary energy waste and increased greenhouse gas emissions. The analysis draws on existing literature, case studies, and European policy frameworks to identify effective strategies for addressing this issue. Results highlight three main areas: the potential of reducing electricity demand through efficient lighting design and smart management systems, the integration of renewable energy sources such as solar power into urban lighting infrastructures, and the role of technological advancements in LEDs and adaptive control systems. Case studies from European cities, along with projects in environmentally sensitive regions, demonstrate measurable energy savings and ecological benefits. Policy directives provide the regulatory basis, though challenges in implementation and public awareness remain. Overall, the findings suggest that mitigating light pollution represents both an environmental necessity and an economic opportunity, supporting sustainable urban development and improved quality of life.
