The unbridled energy consumption of our wireless revolution, 4G, 5G and the Internet of things is contributing to climate change. 5G requires millions of new cellular antennas called “small cells” -basically shorter cell towers- to be built in neighborhoods directly in front of our homes. These 5G antennas are to connect with billions of new wirelessly connected “smart” devices referred to as the Internet of Things (IOT). Massive Increases in 5G Equipment = Massive Increases in Energy Use

Researchers are warning us that the energy consumption of 5G and the IOT is growing and projected to skyrocket. 5G is NOT Sustainable The demand for technology is outstripping the increase in efficiency. Energy consumption will rise sharply due to the ever-increasing IOT energy demands at every stage of the lifecycle of 5G equipment, from device manufacture to data centers to data transmissions, and networks.
- 70.2 million “small cell” tower bases to be installed by 2025.
- 500 billion devices are expected to be connected to the Internet by 2030.
- 8.9 billion mobile phone subscriptions worldwide by 2024.
- 60% growth a year in the production of wireless peripherals (Wi-Fi/ Bluetooth speakers, appliances, wearables).
- 7-fold increase in mobile data traffic globally is projected between 2017 and 2022.
In economics, the Jevons Paradox is when technological progress increases the efficiency with which a resource is used, however demand and consumption increase as well. Thus- the end result is the overall increased use of the resource, despite efficiency gains.
5G is an Energy Hog “A lurking threat behind the promise of 5G delivering up to 1,000 times as much data as today’s networks is that 5G could also consume up to 1,000 times as much energy.” -IEEE Spectrum, 5G’s Waveform Is a Battery Vampire
We Must Consider the Environmental Footprint of the Digital Ecosystem. “Behind each byte we have mining and metal processing, oil extraction and petrochemicals, manufacturing and intermediate transports, public works (to bury the cables) and power generation with coal and gas. As a result, the carbon footprint of the global digital system is already 4% of the global greenhouse gas emissions, and it’s energy consumption rises by 9% per year.” – Jean-Marc Jancovici, President of The Shift Project, member of the French High Climate Council
5G Harms Bees, Trees and Birds “The electromagnetic radiation standards used by the Federal Communications Commission (FCC) continue to be based on thermal heating, a criterion now nearly 30 years out of date and inapplicable today.” -The Department of Interior in a 2014 letter on the impact of cell towers on migratory birds.
- Research finds bees and pollinators absorb the higher frequencies of 5G between 3% to 370% higher leading the scientists to warn, “This could lead to changes in insect behaviour, physiology, and morphology over time….”
- Research finds wireless frequencies interfere with birds’ navigation systems, and their circadian rhythms, and can harm their development and reproduction.
- Research finds trees can be harmed by the radiation from cellular antennas. Effects include altered growth, thinner cell walls and adverse biochemical changes.
EHT has a compendium of research on impacts to trees, bees and birds here.
Damage to the Tree Canopy Trees play a vital role in mitigating climate change, sequestering millions of tons of carbon that would otherwise pollute our climate. The installation of 5G equipment often requires heavy pruning and digging. This will clearly impact the canopy and root system of our trees. Read the Sierra Clubs testimony to Washington DC about the impact to trees from the 5G small cell deployment.
All things wireless is NOT the answer. “Wireless devices, antenna networks, and data centers are consuming an ever-increasing portion of the global energy supply, based largely on coal…” -“Re-Inventing Wires: The Future of Landlines and Networks” According to the Centre for Energy Efficient Telecommunications;
- “Our energy calculations show that by 2015, wireless cloud will consume up to 43 TWh, compared to only 9.2 TWh in 2012, an increase of 460%. This is an increase in carbon footprint from 6 megatonnes of CO2 in 2012 to up to 30 megatonnes of CO2 in 2015, the equivalent of adding 4.9 million cars to the roads. Up to 90% of this consumption is attributable to wireless access network technologies, data centres account for only 9%…”
- “…wireless access networks are clearly the biggest and most inefficient consumer of energy in the cloud environment.” Solutions for Fast, Safe and Secure Internet Connections Do Exist.
A national wireline system can guarantee for everyone a superior foundation of Internet access, unequaled connectivity speed, safety, privacy, security, energy efficiency, and long-term sustainability.
Wireless devices use energy even when you are not using them- in standby mode.
The most significant factor driving the increase in network standby-related energy use of connected devices is the increasing number of connected devices. Some of the key products that appear to be increasing global network standby energy use are:
- Voice assistant speakers
- Wi-Fi-connected IoT devices and other Wi-Fi-connected appliances
- Media devices, such as STBs and OTT media players
