Computers, electronic devices and digital infrastructures are consuming ever-increasing amounts of electricity. This is confirmed by Milena Gabanelli who, during her DataRoom on Corriere della Sera, reports interesting data on the harmful emissions produced by the technology and their use. In 2008, for example, digital technologies used in the transmission, reception and processing of data and information (ICT) contributed 2% to global CO2e emissions; in 2020 they reached 3.7% and will reach 8.5% in 2025, the equivalent of the emissions of all light vehicles in circulation.
The electricity that powers appliances and lights homes also generates small magnetic fields that exist everywhere. A research team, headed by Penn State scientists, built a device that delivers as high as 400% higher power output when compared to other advanced technology when working with low-level magnetic fields similar to those seen in buildings and homes. The technology holds major implications for designing smart buildings, which will need self-driven wireless sensor networks to perform things like remote control of systems and tracking energy and operational patterns, the researchers said.
A study published in the journal Science last week, notes that while global data-center energy consumption has risen over the past decade, a predicted explosion in power consumption by data centers has not manifested thanks to advances in power efficiency and, ironically enough, the move to the cloud. Data centers accounted for about 205 terawatt-hours of electricity usage in 2018, roughly 1% of all electricity consumption worldwide. This represents a 6% increase in total power consumption since 2010, while global data center compute instances rose by 550% over that same time period.
A new study from Greenpeace and North China Electric Power University reports that in five years, China’s data centers alone will consume as much power as the total amount used in Australia in 2018. The industry’s electricity consumption is set to increase by 66% over that time. Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, which is equivalent to 21 million cars.
Protecting network traffic from the noise and heat inherent with PoE is critically important. Download Berk-Tek’s white paper for an overview of the real-world challenges that are taxing copper-based cabling systems as IP convergence becomes more prevalent.
The IoT is a broad term that defines anything connected as part of a network, capable of both sending and receiving data. The majority of this network is based on sensors, and it’s these devices that will power Energy-as-a-Service. Current energy production focuses on a centralized grid and while it has served us well in the past, decentralized microgrids are emerging to prevent power disruptions, monitor energy usage and even transition into green energy.
