One industry that’s not suffering in the economic downturn is information technology. The demand for IT keeps growing. But that worries some people. Our growing number of internet searches and data storage is using a lot of energy. Julie Grant reports on how some companies are making their IT more environmentally friendly – and saving money in the process:

(sound of an internet search with a tea kettle)

By some estimates, two Google searches create the same amount of carbon dioxide as boiling water for a cup of tea.

Most people don’t think about the greenhouse gas emissions caused by their internet use. But there are about 200-million
searches globally each day – and each search kicks a lot of servers into gear. It adds up.

Albert Esser is an IT expert with Dell Computers. He says
in just a few years internet use could use 3% of the nation’s energy supply. That’s a lot of carbon pollution.

“From a global greenhouse perspective, that’s about the same as the airline industry will cost.”

But Esser says computers don’t need to use that much energy. Most computer systems are so
in-efficient today – that they’re wasting more than 90% of the energy they use.

(sound of a data center)

This is a data center. It’s filled with racks and racks of servers.

A hundred different companies rent space here. Each company has its own set of servers – to coordinate its email systems, word processing, online credit card transactions – all kinds of programs its employees and customers use.

But data centers can be real energy hogs. They need electricity to run all those servers. That creates a lot of heat, so they also need air conditioning. One data center can use as much electricity as a good-sized town.

(sound of electricity in the data center)

“You can hear the electricity, in here. The piles of batteries you see are attached to the uninterruptable power supply.”

Bryan Smith is marketing director for Expedient, which runs this and other data centers around the country. His customers want their computers to be fast, and that takes a lot of power.

But Smith says the data center does everything it can to cut down on energy usage.

“It’s obviously in our best interest to be energy efficient, because we’re the ones paying the power bill.”

So, they’ve set up the server racks to make them easier to cool. They’re also building a system to pull in cool air from the outside, instead of using so much air conditioning.

Some companies that use the data center are also starting to use software to create what are called virtual servers.

“This rack here is a virtualization rack, so you’ve for one rack here that has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 computers in it. Right? So each one of these servers is equal to 16 physical servers.”

And so for each of those ‘virtual servers’ they can turn off
15 actual servers.

But, even with all that saved space and energy, Expedient’s data centers are growing faster than they ever anticipated.

This one built in Cleveland only two years ago is just about sold out of space – so Expedient is building another data center next door.

Albert Esser at Dell says the most environmentally friendly way to build data center is not to build one at all.

He says making better use of old centers, with virtual computers and other energy efficiency measures, produces a lot less pollution. And it saves money.

“I think the economic downturn, as harsh as it sounds, is the best thing which could ever happen to green IT. Because the economic pressures will make people think much harder to just build a new data center without changing the way they operate it.”

So IT is learning what a lot of companies are learning – that going green can mean saving energy – and that’s better for the bottom line.

Wifi System to Help Save Money on Utility Bills?

  • If only your electricity meter could talk... (Photo by Kenn Kiser)

If the summer heat’s had you cranking up the a/c… you might be anxious about getting a big bill in the mail. Imagine if your house could send you an email to warn you that you’re spending a lot… before the bill arrives. The Great Lakes Radio Consortium’s Rebecca Williams explains:

If the summer heat’s had you cranking up the A/C, you might be anxious about
getting a big bill in the mail. Imagine if your house could send you an
email to warn you that you’re spending a lot before the bill arrives. The
Great Lakes Radio Consortium’s Rebecca Williams explains.


In the future, your electricity meter could talk to you.


You’d be able to type into your computer how much you want to spend on lighting and cooling
your house each month. Using wireless technology, your utility meter would
then send you an email when you’re going over those goals.


It’s a system created by mechanical engineering students at the University
of Michigan. Professor Steven Skerlos advises the team.


“As a recent homeowner, it was very obvious to me that even I had little
awareness of the impact that I was having and the consumption of course
until it was way too late. The bill comes a couple months later and you
can’t go back in time and turn down the thermostat or use less water.”


Skerlos says the system can also be used in water and gas meters.


But it might be several years before you can get the new system. Skerlos
says he’s had interest from the companies that make the meters, the next
step is getting utility companies to buy in.

Packrats Hooked on Freecycling

We all have things that we no longer use hidden in our closets, or stuffed away in the attic, or crammed into the garage. It’s not that we’ll ever use them, but we can’t bear to just throw them away. They’re still good. Now, a new service is matching up people who want to get rid of things with people who want those things. In part of an ongoing series called ‘Your Choice; Your Planet,’ the Great Lakes Radio Consortium’s Rebecca Williams explores freecycling:

We all have things that we no longer use hidden in our closets, or stuffed away
in the attic, or crammed into the garage. It’s not that we’ll ever use them, but we
can’t bear to just throw them away. They’re still good. Now, a new service is
matching up people who want to get rid of things with people who want those
things. In part of an ongoing series called ‘Your Choice; Your Planet,’ the Great
Lakes Radio Consortium’s Rebecca Williams explores freecycling:


I’m a packrat. I just wanted to make that clear right from the beginning. If you’re honest with yourself, you’ll probably confess you’re a packrat too.


But even I know when there’s something taking up space in my house that HAS to go. In the back of my closet, there’s a large, heavy, men’s wetsuit.


You know, a SCUBA diving suit. A relative gave it to me when he moved away. Now, I’m not a diver. I’m not even really a snorkeler. But I’ve kept it for two years. You know, just in case.


I need a little help getting rid of things. So, when I heard about freecycling… I thought, “This is it. This will help me face my inner packrat.”


Freecycling uses email groups to connect people in their hometowns. It brings together one person with their broken telescope… and that one person who needs – or just wants it.


The only rule – everything has to be free. No money, no trading. And also, you meet the giver or taker in person.


It’s Deron Beal’s idea. He manages recycling crews for businesses in Tuscon, Arizona. One day a year ago, he found himself with a warehouse full of stuff.


“We had a lot of the businesses we recycle with
downtown giving us old desks or computers, saying, can you do something with this. I’ll be darned if we got so much stuff in, I figured, let’s open this up to the public and set up the freecycle network.”


Beal emailed some friends and nonprofits. At first, he says it was just he and his friends giving each other stuff. But in just a few months, freecycle turned into a verb. Beal set up a website, freecycle-dot-org. And put instructions up so people could start freecycling in their own cities. Now, more than 90-thousand people all around the world are doing it.


So… I went to see the freecycling guy in my area, Aaron Liepman. He moderates two freecycle groups. He makes sure everything stays free, and steps in if people start arguing. He also helps packrats like me freecycle.


(sound in, typing)


Aaron sets me up on his computer.


“So, let me sign out and you sign in. (clicking) So now you type in your subject, just like an email message.


RW: “Offer: wetsuit. What else?”


“Wetsuit, SCUBA wetsuit. (crinkles, zipper noise) Looks like it’s a size large, that’ll be useful information. It has a little hat to keep you warm in the water (laughs).”


(typing out)


We look over my post, and I click Send.


So, I’ve started cleaning out my closet. But I’m not totally converted to this freecycling idea. I mean, really, aren’t we just moving our stuff from one house to the next? That doesn’t really cut down on consumption, does it?


I turned to University of Michigan professor Raymond DeYoung. He studies people’s buying and recycling habits. He thinks freecycling probably won’t change our buying habits all that much.


“Because we’re never going to be able with freecycling to get the new, get the novel, get the big, because by definition it’s already been bought, it’s already old, it’s the smaller. So it can’t impact our entire consumption behavior.”


DeYoung says, for freecycling to really succeed, we’d have to stop getting bigger houses. And stop filling them up with more and more things. But it’s hard, even for people who want to try to get by with less stuff.


I guess a wetsuit is a good first step.


It’s been a couple days, and I’ve gotten four messages. The first came five hours after my posting. From Shawn… he wrote: “I’ll take the wetsuit.” But he didn’t sound that excited.


In freecycling, you can use “first come, first serve” to decide who gets your item. But you don’t always have to. And I kind of wanted my wetsuit to be appreciated… you know, actually get to see the water. So I waited a couple days. Then, I got Kelly’s message. She wrote: “WOW!” in all capital letters and said her son would love the wetsuit… for snorkeling.


So I emailed Kelly. And we set up a place to meet in downtown Ann Arbor.


(street sound up)


“Wetsuit!” (Oh, are you Kelly?) “yeah, I’m Kelly.. (Hi, I’m Rebecca. This is the wetsuit.) Great!”


Kelly’s been freecycling for a month. And she says she’s hooked.


And judging from the postings, a lot of people are. They seem to like getting other people’s beer can collections and turtle sandboxes.


But some on the list worry it’s getting to be too much of a good thing. People have started to ask for laptops, and houses… and a time machine, any condition.


“I think because it’s so new, some people are asking for funny things, like don’t we all want cash, and a Lamborghini (laughs). I just laugh at those and go on.”


Kelly says she thinks the network will probably get past that after awhile, leaving behind just the really devoted freecyclers.
