• MPs cast doubt on whether energy efficiency gains can keep offsetting rising power demandA cross-party group of MPs has raised doubts over whether the growing energy demand from digital technology and the proliferation of internet-connected gadgets can continue to be offset by energy efficiency improvements.More efficient smartphones, networking gear and data centres have so far largely staved off increased power demand from the internet and computing – which now accounts for about 6% of global electricity use.

  • Billions of internet-connected devices could produce 3.5% of global emissions within 10 years and 14% by 2040, according to new research, reports Climate Home NewsThe communications industry could use 20% of all the world’s electricity by 2025, hampering attempts to meet climate change targets and straining grids as demand by power-hungry server farms storing digital data from billions of smartphones, tablets and internet-connected devices grows exponentially.The industry has long argued that it can considerably reduce carbon emissions by increasing efficiency and reducing waste, but academics are challenging industry assumptions. A new paper, due to be published by US researchers later this month, will forecast that information and communications technology could create up to 3
