The use of led technology and biomass to power public lighting in a local context: The case of baeza (Spain)
MetadataShow full item record
The impact of public lighting on consumed energy, financial cost, use of raw materials, and the environment is a major concern nowadays. The high amounts of energy needed to satisfy the increasing demands of cities around the world has led researchers to look for alternatives to classical fossil sources, with low implementation in public lighting up to date. In this context, circular economy (CE) proposes a new perspective of engineering based on smart design for the future life of products where even wastes have an added value as technological nutrients for other applications. A convergent consideration of CE and the urgent necessity of more sustainable public lighting leads to this proposal. The ad hoc use of a local biomass plant for powering the public lighting of one small city is considered, and important conclusions reinforcing the link between lighting and CE are presented. © 2018 by the authors.
