Chances are that you’ve visited the
website google.com. Google is
not only a leader in online tech, but
it’s also investing in high-tech
alternative energy, especially different
kinds of solar power. Lester Graham
talked with Google’s Green Energy
Czar – yes, that’s his real title – Bill
Weihl. His job is not only
to make Google more energy efficient,
but to investigate and invest in new,
cleaner energy use and generation:

Lester Graham: Last year, a report indicated performing two Google searches from a desktop computer could generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea. How true is that?

Bill Weihl: We think, as, in fact, does the scientist who was behind most of the data there, that that report was actually off – that you, in fact, could do several hundred Google searches, if not more, for the emissions that are involved in boiling enough water to make a cup of tea.

Graham: What is Google doing to reduce energy consumption, or, at least, reduce greenhouse gas emissions?

Weihl: We have cut our energy consumption in our data centers – data centers are the, you know, big facilities that contain lots and lots of servers. We have cut the energy usage in those facilities by over 50%.

Graham: Is there anything we can do so that when we do use Google we’re being as energy efficient as possible?

Weihl: If you’re buying a new computer, look for one that’s energy efficient. And in the US that means look for one, at a minimum, that’s Energy Star compliant. Laptops also tend to be more energy efficient than desktops, in part because just to make the battery last long enough to be useful, they have to work really hard in designing them to make them energy efficient. The second thing you can do is when you’re not using your system, when it’s sitting there idle, you can set it so that it will go to sleep automatically, or manually, if for some reason it doesn’t go to sleep automatically, you can very easily tell it to go to sleep. That’s much more convenient, obviously, that shutting it down, having to reboot, and restart everything. And it uses about the same energy in stand-by mode as it does when it’s off – which is, in the order of 1 to 5 watts, far less than it uses when it’s just sitting there idle with the screen on and doing nothing.

Graham: Let’s look beyond the world of computers. Google has invested in research for energy efficiency in cars and electric generation. You have a program that’s called ‘R.E. is less than C’ or ‘renewable energy for less than the cost of coal.’ That’s ambitious. Is it realistic?

Weihl: First of all, it’s hugely ambitious. Secondly, I believe it is realistic. And third, I think it’s absolutely necessary. Today, coal is, by far, the cheapest form of energy, or electrical energy, that we consume, except perhaps for hydroelectric power, which is comparable in cost. But at least in this country, and most of the developed world, we’re not going to be building large amounts of new hydroelectric generating capacity. We’ve already dammed most of the rivers that are worth damming. We are, however, still building new coal plants. And coal is not only very cheap, but also it is, by far, the dirtiest, in terms of greenhouse gas emissions, of any of the sources of energy that we use. So I think it is necessary, in terms of dealing with the climate crisis that we are facing, to find a way to, over time, replace coal with cleaner sources of energy. And the only way, as a society, I think that we’re going to do that is if it makes economic sense. So that’s why we really started to focus on this initiative we call ‘R.E. less than C’ – to really try to drive innovation as rapidly as possible on the technology for generating renewable power to try to drive its cost down very quickly.

Graham: Bill Weihl is the Green Energy Czar for Google. Thanks very much for your time, I appreciate it.

Weihl: My pleasure. Thank you.

Getting involved in a social
or environmental cause these
days is as easy as clicking
your mouse. Some people think
grassroots activism is just
changing its face as technology
changes… but other people think
we’re becoming slackers. Rebecca
Williams explores whether we’re
a nation of slack-tivists:

The other day I met this guy, Patrick Diehl. And I was trying to get him to describe himself.

“Uh, I’m a Pisces and I enjoy long walks on the beach and horseback riding; good sense of humor; still gets pimples.”

Add to that: slack-tivist. That’s a slacker activist. But he was telling me he wasn’t always this way. For twenty years, he was one of those door knocking, envelope licking activists. He worked for a governor. He used to drag his little daughter to rallies. Now he’s just burned out.

“I could get on the phone and call someone about an issue but I choose to sit down on Facebook and hit three mouse clicks and a return and feel good about myself.”

And lately, his slacktivism has hit a brand new low.

(sound of mouse clicks)

“My little green patch is dry. That means I’ve been neglecting it.”

If you’re a Facebook virgin, the Lil’ Green Patch is this application that lets you send plants to your friends’ online gardens. The idea is, the more you play, the more money advertisers will give to save the rainforest.

“Rebecca: “So wait did you actually do this for a while?”

Patrick: “Yeah!”

Rebecca: “And you felt good about it.”

Patrick: “Yes! I thought my spending time on here is leading to something bigger than myself.” (laughs)

But then, Patrick got in trouble. His wife – Anita – said he was just spending way too much time online. Lil’ Green Patch died. He’d rather play another online game, like Mafia Wars.

But you know, at least at one time Patrick was very active. Some people think clicking on a little green patch is their contribution to a better world.

“That’s a trending topic, that’s a trending term, slacktivist.”

Apollo Gonzales works for one of those big environmental groups, the Natural Resources Defense Council. He’s what’s called a netroots manager. You might say it’s his job to get slacktivists off their butts.

“If you measure the one click activism, or slacktivism, against someone who’s visiting their representative on the Hill once a year, then yeah I think it’s on the low end of what can be done. But you’ve got to start somewhere with a lot of these people.”

So, Apollo blogs and tweets and uses online social media to get people talking. Because talking sometimes actually leads to doing something.

“We have a world where we are more connected than we ever have been, and a world where we can share our stories faster and more richly than we ever have been able to. And that’s great for people who are fighting for a cause.”

And there’s actually some research to back this up.

Scott Campbell studies new media at the University of Michigan.

“There have been some studies recently that show when people use text messaging as reminders to go out and vote, we do see significant increases in voter turnout.”

He says cell phones and the Internet are basically giving us more ways to communicate – and that’s good for us as a society. But he says we do have to be a little careful – because if all our online friends think like we do, we can become little isolated e-communities.

Basically, the more Facebook friends you have, and the more new ideas you can share, the better.

So if you want to be a better slacktivist, you might have to make some choices. You could sign a million online petitions. I mean there are 15,000 environment causes on Facebook. And then there’re all those other things, like Mafia Wars, and other distractions that people like Patrick have to deal with.

Patrick: “I’ve been kidnapped to Barcelona but I’m gonna ignore that.”

Anita: “See you just say ignore, ignore it!”

Patrick: “Someone just sent me a slap on the rear end. I’m gonna ignore that. I probably wouldn’t but my wife is right here so I’m going to ignore that.” (both laugh)

With distractions like these… even slacktivism’s getting to be hard work.

Saving Energy in Online Activities

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:

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.

Google’s Power Meter

  • Google's new smart meter technology will eventually let consumers see how much energy each appliance (like a fridge) in their home uses, in order to help them find ways to reduce their monthly bill. (Photo by M. Minderhoud, Courtesy of Wikimedia Commons)

There’s 11-billion dollars in the new economic stimulus plan for upgrades to the electric grid and so-called smart meters. These smart meters hook up to your home and give the utility company real-time feedback on how much energy you’re using. Rebecca Williams reports Google is working on a way to let you see that information:

There’s 11-billion dollars in the new economic stimulus plan for upgrades to the electric grid and so-called smart meters. These smart meters hook up to your home and give the utility company real-time feedback on how much energy you’re using. Rebecca Williams reports Google is working on a way to let you see that information:

Google’s system is called PowerMeter. It’s in beta testing right now but the idea is: if you get a smart meter, you’ll be able to see exactly how much energy your TV, fridge and computer use.

The system will hook into the info utility companies draw from your home. Then, you can log into your secure i-Google website, for free. And get real-time feedback so you can figure out how to spend less on your power bill.

Kirsten Cahill is a program manager at Google. She says they’ve been testing the PowerMeter around the office:

“I think people are surprised about things like their oven; how much the oven uses or the microwave. Things that you using every day that are actually, you know, pretty huge energy users.”

It’ll probably be a year or more before the Google system is open to everybody.
