Empowered states that 5G will increase energy demands and is not energy efficient.
Excerpts from Empowered
“The information and communications technology (ICT) sector is responsible for 2-3% of global emissions – a number that is expected to increase to 7% by 2030, driven in part by 5G adoption.”
“5G is projected to increase total network energy consumption by 150-170% by 2026, and a study by 451 Research found that 94% of polled telecom companies expected their energy costs to increase as a result of 5G rollouts.”
“We’re paying for the power, we’re paying for the higher power supply, and we’re paying to move the heat away into a giant block of aluminium serving as a heat sink,” says Earl McCune, a professor in the electronic circuits and architectures group at Delft Technological University (TU Delft) in the Netherlands.
So while it is true that the per bit energy use is lower in 5G, the higher number of bits moving through a 5G system still means 250% higher overall energy demand compared to 4G.
“The energy efficiency of 2G was 60%, meaning of every 10 watts consumed, six were used to transmit data. This efficiency rating dropped to 20% in 4G systems, and just 10% in 5G systems, meaning 9 watts are wasted for every one used to transmit data.”
“This gets even worse for 5G networks running on 4G hardware and using millimeter-waves: these setups have just 1% energy efficiency, which is worse than old-fashioned incandescent light bulbs.”
The energy consumption issues of 5G are also detailed in the following reports:
