The traditional role of the lighthouse keeper has largely been replaced by sophisticated automation and remote monitoring systems. How does modern lighthouse design consider environmental impact? Modern lighthouse design takes into account the environment by using eco-friendly materials, minimizing light pollution, and reducing the carbon footprint with energy-efficient technologies and ...
