Every click has a cost: Singapore’s push to make digital use more sustainable
As AI and cloud use surge, the city-state explores new ways to cut the rising energy footprint of digital services. By Taejun Kang Your smartphone feels clean – no exhaust pipe, no smokestack. Yet streaming an hour of video uses about 0.037 kWh of electricity, equivalent to running a ceiling fan for about three to four hours. When scaled across billions of global searches, streams and artificial intelligence (AI) interactions each day, the energy demand behind routine digital activity is substantial. “The environmental impact of our digital consumption is far more significant than most people realise,” said Dr Lawrence Wee, director of business and ecosystems at Singapore’s Infocomm Media Development Authority (IMDA). As part of IMDA’s BizTech Group, his team focuses on advancing the country’s digital innovation and sustainability across the tech ecosystem. “We are seeing a digital paradox: the very technologies that offer solutions for climate change are simultaneously driving up energy consumption.” Studies over the past several years have placed the Information and Communications Technology (ICT)’s share of global greenhouse gas emissions between 1.8 and 2.8 per cent, with a more recent analysis estimating it at around 3.4 per cent. Data centres – facilities that house servers and keep the internet, cloud services and digital applications running – are among the most energy-intensive components of this ecosystem because they require continuous power and cooling. Singapore is no exception to this trend. The city-state hosts one of the region’s densest clusters of data centres, with about 1.4 gigawatts (GW) of computing capacity from 70 data centres, which power everything from e-payments to food-delivery apps. By regional standards, this capacity is unusually concentrated. Unlike neighbouring countries such as Indonesia, Malaysia or Thailand, where data centres are spread across vast land areas and multiple power grids, Singapore compresses a similar scale of digital infrastructure into just 734 square kilometres, intensifying pressure on electricity supply, land use and […]
