Entropy-TOPSIS Method to Study the Factors Affecting Light Pollution

Abstract

The problem of light pollution, which arises from the excessive or poor use of artificial light sources, has become a global issue. Identifying and solving the light pollution problem will have a positive impact on human and ecological environment. In this paper, the entropy-TOPSIS method addresses the degree of influence of each factor on light pollution and finds appropriate improvement measures based on the characteristics of data that may affect light pollution factors. The entropy-weighting method is used to score different areas with different degrees of light pollution, and then the weights of each factor are obtained, and the TOPSIS method is used to score the degree of light pollution in each area based on the superiority and inferiority distances. Finally, the light pollution evaluation model is obtained.

Converting Human Power into Electricity: Current Status and Future Directions

“…The energy released per gram of glucose is equal to the energy released per mole divided by the molar mass, and this value can be converted to kilocalories (kcal) as shown in equation (4).…”

“…The manageable current environmental impacts should not lead to complacency, as crossing a critical threshold could unleash profoundly detrimental consequences for humanity. Hence, it is imperative for humans to adopt relatively positive measures in the pursuit of sustainable development, safeguarding our planet and securing a brighter future for all [3,4].…”
