Saudi Researchers Create More Efficient Streetlights by Inverting Nanoplastic Technology

Scientists in Saudi Arabia have created an innovative nanomaterial coating for streetlights aimed at enhancing energy efficiency by reducing heat loss. Published in the journal Light: Science & Applications, the research highlights how traditional streetlights account for 1-3% of global electricity demand, contributing significantly to greenhouse gas emissions. The new coating, known as nanoPE (nanoporous polyethylene), enhances thermal management by allowing infrared light to escape while reflecting visible light, thereby improving cooling and luminous efficiency. Lab tests showed temperature reductions of up to 7.8°C in LED lights, yielding efficiency improvements of about 5%, which could lead to substantial annual energy savings and a reduction of approximately 1.3 million metric tons of CO2 emissions when applied widely in the U.S. This innovative approach presents a promising solution for sustainable street lighting, particularly benefiting city councils facing high operational costs.
