Saudi researchers develop innovative nanope technology to cut LED carbon emissions
The study highlights that nearly 75 per cent of input energy in LEDs is lost as heat
A groundbreaking study has unveiled a solution to reduce carbon emissions from LED streetlights. The research explores the use of nano polyethylene (nanoPE) to enhance thermal radiation emission, effectively lowering LED temperatures and improving energy efficiency. This is reported by Saudi Press Agency (SPA).
The study highlights that nearly 75 per cent of input energy in LEDs is lost as heat, which accelerates component degradation. By incorporating nanoPE, more than 80 per cent of infrared radiation escapes into the sky, while over 95 per cent of visible light is reflected downward, maximising illumination and efficiency.
The research team demonstrated that nanoPE, a modified polyethylene plastic, can be engineered with nanoscale pores – 30 nanometres in size, nearly 1,000 times thinner than a human hair – to selectively reflect visible light while allowing infrared radiation to dissipate.
With lighting accounting for around 20 per cent of global electricity consumption and 6 per cent of greenhouse gas emissions, this innovation presents a scalable and cost-effective approach to reducing energy waste and promoting sustainable urban development.

Vladimir PutinPresident of Russia"We are developing mutual trade, which is growing; it increased by over 12 per cent last year. We have a joint commission working in this sphere. Our focus is on agriculture, shipbuilding, information technology and energy, including nuclear power. We have signed a free trade agreement between the Eurasian Economic Union and Indonesia. Jakarta is our reliable and old friend within ASEAN. We are working together at all international platforms, including the UN" -

Joao Paulo CapobiancoBrazilian Minister of the Environment and Climate Change"The BRICS countries have a very high level of responsibility because they share an important part of the world's biodiversity, landscapes, populations, food production and water resources. So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification"
