Dirty data: Firms count environmental costs of digital planet

THE STAR ONLINE

Technology is often touted as a solution to the world’s environmental challenges, but it is also part of the problem: industry executives are facing rising pressure to clean up their energy and resource-intensive business.

How much energy, for example, does it take to send a one-megabyte email?

Around 25 watts per hour, representing 20g of carbon dioxide emissions, according to France’s CNRS research centre.

It might not seem like much, but the Radicati research group expects 293 billion emails will be sent every single day this year and the power needs to be generated – mostly from fossil fuels.

Apps can quickly drain and shorten the life of phone batteries, with Snapchat a particularly “heavy” messaging service because it automatically turns on the camera.

Then there are the server farms crunching mammoth amounts of data worldwide, which require huge amounts of electricity both to run and to power air conditioning which keeps the equipment from getting too hot.

“Under the current global energy mix, the share of greenhouse gas emissions from information and communication technologies will rise from 2.5% in 2013 to four percent in 2020,” the French think-tank Shift Project said in a recent report.

That makes the sector more carbon-intensive than civil aviation (a 2% share of emissions in 2018) and on track to reach automobiles (8%), it said.

Skyhawk air conditioners, new homes, overwhelm electrical grid

Kevin McCallum, THE PRESS DEMOCRAT
A normally quiet east Santa Rosa street has been turned into a noisy power station to meet the growing power demand by large, air-conditioned homes and new development that threatened to overwhelm the area’s power grid.
Pacific Gas and & Electric set up a series of mobile power generators on Great Heron Drive in the Skyhawk neighborhood last week after power went out to 109 customers in the area Aug. 31, PG&E spokeswoman Deanna Contreras said.
Worried by a forecast that called for triple-digit temperatures over the Labor Day weekend, the utility wanted to make sure it could keep the lights and air conditioners on in the area, she said. The mercury ended up hitting a new record of 110 degrees in Santa Rosa last Saturday.
The neighborhood of mostly larger single-family homes built in the 1980s and 1990s had an undersized electric infrastructure that was stressed when people turned on their central air conditioners.

California grid operator calls for voluntary conservation during heat wave

The operator of California’s power grid has issued a so-called Flex Alert calling for voluntary electricity conservation between 2 p.m. and 9 p.m. on Tuesday and Wednesday, the expected peak of the current heat wave.
The California Independent System Operator says consumers shouldn’t use major appliances during those hours and should set air conditioners to 78 degrees or higher and turn off unnecessary lights to ease strain on the grid.
The forecast peak electricity usage is expected to exceed 47,000 megawatts each day.
