For Every Watt We Use On the Internet, We Save 10 Watts!

The American Council for an Energy Efficient Economy rocks. They have put numbers to what I have long expected to be true. Folks who complain about how much energy computers waste are crazy. Computers save tons of purchase levitra online energy, while, themselves, using less energy than the lightbulb used to light the workstation. And now we know how much.

The study focused on a metric called "energy intensity." Basically, that's the amount of energy necessary to produce a dollar of economic output. The first major drop in energy intensity occured after the oil crisis in the we recommend cheapest viagra in uk 1970s. That was a cost-based drop, not generally the ideal.

Then, after OPEC lost its stranglehold, energy intensity stopped dropping because energy was once again cheap. But then, starting in the late 1990s, energy intensity began to drop significantly again. This drop was unrelated to levitra profesional energy costs and was, in fact, a technologically spurred change.

Computers were helping us become more efficient. First, by using their power to design more efficient practices. And second, and much more significantly, by allowing people and things to travel digitally, instead of physically.

Telecommuting a couple days per week, reading news online, emails, document downloads, and instant messages all allow people and things to travel while consuming much smaller amounts of energy. What's more, online shopping has reduced trips to retail stores, resulting in significant energy savings.

Energy intensity has continued to drop more than 2% every year since the Internet first appeared. Without the Internet, the paper's authors suggest that we would need one billion more barrels per oil per year! Indeed, ever kilowatt/hour we spend on the Internet looks to have saved about 10 kilowatt/hours of energy.

Not that I need another reason to spend time online...

Are Newspapers Greener than Websites?

An interesting little controversy has popped up in the last few weeks. It all started with Chris Anderson, editor-in-chief of WIRED and inventor of The Long Tail, telling the world that the hard copy of his magazine is greener than the online version.

Now, not to cialis shop be too much of a skeptic, but the super active cialis 20mg australia hard copy of WIRED obviously makes more money than the online version, so it's not surprising that Anderson would promote it. But leaving that aside, his logic goes like this: Magazines and Newspapers Sequester Carbon!

Which, in a manner of speaking, they do. Trees take carbon dioxide out of the air, then the paper industry processes it into paper, and then we lock that carbon away in landfills. So it makes perfect sense until you add in the clear-cutting of Canadian forests, toxic chemicals used to process and bleach the paper, and all of the fossil fuels necessary to power the processing and distribute the paper where it needs to go.

Now a study (PDF) has been released that actually gives numbers to Anderson's argument. And, at first glance, it looks a bit damning. Even taking into account all of the energy used to process and distribute paper, the numbers seem to show that newspapers produce less carbon than websites by simple virtue of buy online pill cialis not needing power during viewing.

Unfortunately the Sweedish study still does not take into account the viagra cialis levitra environmental effects of clear-cutting forests or releasing toxins in bleaching and recycling paper, only the carbon effects. And, what's worse, they seem to have some ridiculous numbers on the energy use of home computers. How about 160 watts for your computer and 120 for your screen? I don't know about you, but I have a pretty high-end system that pulls about 100 watts total, including peripherals and only here viagra online order the screen. Of course, those numbers plummet further if you're reading on a laptop or PDA, as many now are. Maybe the study was done back when people will still using CRT monitors.

In any case, I think this points to a troubling trend in environmental accounting. The focus on carbon and global warming has made everything oh-so-simple to calculate. And as long as we don't worry about any of those old, passe elements of environmentalism (toxic pollution, habitat loss, etc) then we can see the answers clear as day.

Unfortunately, that's now how the Earth works. Global warming isn't the only environmental problem we face, and I'm tired of people who pretend like it is. But one thing remains clear, using electrons only gets cleaner as our world adopts renewables and computers and servers become more efficient. The logging industry, it seems, isn't planning on stopping the clear-cutting any time soon.

Robots Could Replace Adorable Animals in Toxicity Tests

Well, sometimes we talk about the buy online order viagra environmental benefits of digitizing physical media...but today we're going to talk about the environmental benefits of digitizing physical bunnies.

According to the BBC, scientists are working on ways to buy viagra uk replace live animal testing of tramadol overnight cash on delivery everything from cosmetics to pesticides with "high speed, automated robots" and "live cells grown in a laboratory."

Samples of chemicals will be dropped onto dishes containing human or animal cells grown in the laboratory.

These will then be studied for signs of toxicity using a variety of biochemical and genetic tests.

The ultimate goal is to develop non-animal based testing methods that are rigorous enough to be submitted for regulatory approval.

Sounds preferable to the traditional systems. Of course, it wouldn't be a full approximation of the marvelous beauty and intricate systems of a real-live cute little bunny rabbit. So for pharmaceutical and broader carcinogen and system-wide effects, I'm afraid they'd still go under the knife.

Nevertheless, this would certainly be a step in the right direction.

The Only Reason the 2009 Budget is Green

Bush's $3 trillion budget might not have very many provisions for green technology in it, but, thanks to some clever administration officials, we can gloss over that by saying that the budget itself is a lot greener this year.

In fact, the budget does not physically exist. This makes a tremendous amount of sense, especially considering that the Democratic Congress is diuretics and viagra about to tear through it, delete, and add like crazy. Previously, this deliberation process created constant need for reprinting after reprinting.

And then there's the 3,000 copies of the 2,200-page tome that are given away to buy cheap generic viagra the press and the public every year. Yes, it's a great big waste. But now we can thank the Bush administration for eliminating the paper budget once and for all.

The administration says the move (despite including a Dell Latitude XT Tablet PC so the 40mg cialis president can show it off to Congress) actually saves money. And, of course, they let us know exactly how many trees it saves: 480.

Of course, using the market's most expensive Tablet PC as a glorified PDF reader is pretty foolish. But if you want your own copy of the budget, it's never been easier. Just head to and check the bottom of canadain cialis the page. It's even broken into categories so you don't have to download stuff you don't care about!


The Readius Is Real!

About a year ago we brought you a prototype device that used a low-energy, high-resolution, rollable e-ink display.

The idea was to have a phone that could have a large display roll into a small package. So, basically, the display would be bigger than the phone, allowing for a variety of uses, including book reading.

Well, that device is now officially on the slab to be created and sold.

It's currently called the Readius and is being created by a spin-off of Philip's electronics called Polymer Vision. The device will be slated to compete directly with high-end phones, including the iPhone...but also with Amazon's Kindle e-Reader.

The good news is that because e-ink is such a low-power display, the phone will be light and won't need to cialis professional no prescription charge as frequently as the iPhone. However, that high-res, low-power display has its limitations too, like only being possible and grayscale, and with a long refresh rate that makes it unusable for video.

That won't stop me from sinking a few hundred dollars into it, but as we all know, I'm an e-reader fanboy.
