Do social networkers use up resources?

Dear EarthTalk: What is the environmental impact of so many people now using sites like Facebook and spending so much time online?

The environmental impact of so much online time really boils down to energy usage, which in turn affects the amount of greenhouse gases we pump into our atmosphere. For one, each of us can help by limiting computer time (whether surfing the Web or not) and shutting them down or putting them into sleep mode when we aren’t using them (this can be automated via the computer’s power management control panel).

Also, when shopping for a new computer, consumers and businesses alike can opt for models certified by the federal government as energy efficient with the Energy Star label. If all computers sold in the United States met Energy Star requirements, Americans could pocket $1.8 billion annually in saved energy costs and reduce greenhouse gas emissions by an amount equivalent to taking some 2 million cars off the road.

Individual responsibility aside, the creation and management of more efficient data centers by the major online hubs — especially as we enter the age of “cloud” computing whereby most of the software, content and services we look to our computers for resides online and is served to us as-needed — is what can have the biggest impact. Google, Facebook and Amazon.com are already deeply committed to the cloud computing model, with Microsoft, Yahoo and others following suit accordingly.

For its part, Google has been a real leader in the building of green data centers, even powering them with renewable energy. The company recently released environmental footprint scores for several of its data centers.

While the energy usage required to run its cloud services (Google Search, Google+, Gmail and YouTube) seems huge in the aggregate — it used 260 megawatt hours to power its data centers in 2010 — it boils down to only 7.4 kilowatt hours worth of energy annually per user. Google reports that to provide an individual user with its services for a month uses less energy than leaving a light bulb on for three hours. And because the company has been carbon neutral since 2007, “even that small amount of energy is offset completely, so the carbon footprint of your life on Google is zero.”

In an April 2011 report entitled “How Dirty is your Data?” the nonprofit Greenpeace examined energy sources for the 10 largest IT companies involved in cloud computing, finding Apple, Facebook and IBM especially guilty of getting significant amounts of power from coal-fired power plants.

(Facebook had come under fire earlier this year when reporters uncovered that the company planned to buy electricity for its brand new eco-friendly data center in Prineville, Ore. — one of the greenest such facilities ever designed and constructed — from a utility that derives most of its power from coal.)

Yahoo, Amazon.com and Microsoft scored best in use of renewable alternative energy sources for cloud services.

In the long run, analysts think that the widespread shift to cloud computing will be a great boon to the environment. A report released in September 2011 by Pike Research, “Cloud Computing Energy Efficiency,” predicts that because of the shift to cloud computing and increasing efficiencies, data center power consumption will decrease by 31 percent between 2010 and 2020.

The artistic life of Joelle Sander

"Flowers" by the late artist and writer Joelle Sander.

Cornwall Library

The Cornwall Library unveiled its latest art exhibition, “Live It Up!,” showcasing the work of the late West Cornwall resident Joelle Sander on Saturday, April 13. The twenty works on canvas on display were curated in partnership with the library with the help of her son, Jason Sander, from the collection of paintings she left behind to him. Clearly enamored with nature in all its seasons, Sander, who split time between her home in New York City and her country house in Litchfield County, took inspiration from the distinctive white bark trunks of the area’s many birch trees, the swirling snow of Connecticut’s wintery woods, and even the scenic view of the Audubon in Sharon. The sole painting to depict fauna is a melancholy near-abstract outline of a cow, rootless in a miasma haze of plum and Persian blue paint. Her most prominently displayed painting, “Flowers,” effectively builds up layers of paint so that her flurry of petals takes on a three-dimensional texture in their rough application, reminiscent of another Cornwall artist, Don Bracken.

A Seder to savor in Sheffield

Rabbi Zach Fredman

On April 23, Race Brook Lodge in Sheffield will host “Feast of Mystics,” a Passover Seder that promises to provide ecstasy for the senses.

“’The Feast of Mystics’ was a title we used for events back when I was running The New Shul,” said Rabbi Zach Fredman of his time at the independent creative community in the West Village in New York City.
