Internet's Energy Needs Growing Faster Than Efficiency Gains

Electrons may not weigh anything, but it takes some heavy lifting, both literal and figurative, to point them in the right direction. Reader terrancem writes with this excerpt: "Energy efficiency gains are failing to keep pace with the Internet's rapid rate of expansion, says a new paper published in the journal Science. Noting that the world's data centers already consume 270 terawatt hours and Internet traffic volume is doubling every three years, Diego Reforgiato Recupero of the University of Catania argues for prioritizing energy efficiency in the design of devices, networks, data centers, and software development. Recupero highlights two approaches for improving efficiency: smart standby and dynamic frequency scaling or CPU throttling."

    If your software doesn't have to work or provide utility to human society then you can make it take zero resources and run in zero time. Now it turns out that Java is *very* fast. It turns out that Java's abstractions are up to the developer. N00bs, and those on the lecture circuit, add way to much abstractions. I add the right amount. *one layer of indirection for parts that may be extended*. That is all that is needed.

    Furthermore, through use of Java and XML you can rapidly built systems through massive re-use (and nifty stuff like JAXB which takes much of the pain of using XML away). This allows equally massive *savings* in energy through vastly reduced development time.

    it'll reduce CPU processing requirements by a relatively small amount. One place I worked, we had a XML protocol for storing our data, replacing it with a binary one increased performance by 20%. Now that's not to be sniffed at, but it isn't a panacea.

    What we can do however, is get rid of the script language based web sites. I know there's a low entry barrier when using them, but every site that needs performance ends up writing it in a compiled language, and then C/C++ if they've got sense (Java, and .NET are better, but still not good enough for this problem).

    Now if we had all server computing based on an efficient language, we'd see energy consumption reduced by quite a bit.The super computers we have nowadays could run a great many sites instead of just a handful.

There already has been several designs proposed to make this happen including using old analog types of computer designs instead of digital ones which are far more efficient for some things. Also designing chips to come up with correct answers using the chaos and noise rather than by overriding the noise by pushing high voltage differences between 1's and 0's.

      What happens when our brains don't meet the efficiency standard? What do you propose then?

      I might add that I find efficiency standards to be one of those dumb things that sounds smart at first. First, the obvious solution to efficiency is simply not to do it. Don't have a zillion people, don't have an internet, don't do anything that uses power, etc. Then you achieve perfect efficiency.

      But the moment you decide that there's some things that we really need to be doing (say because those seven billion people aren't going away any time soon), then you are implicitly recognizing that there are more important things out there than efficiency.

      Does the efficiency standard somehow take into account that some uses of energy are more important than conserving energy? Of course not. It's a standard applied blindly to everything. Hence, reason number one why it is a dumb idea.

      Reason number two is that there simply isn't much value in conserving energy. Energy is dirt cheap. That indicates it is plentiful enough that we shouldn't care so much about how efficiently we use it.

      Last, but not least, reason number three is closely related. As I noted, cheap energy means no real reason to conserve electricity. But in the case of expensive energy, everyone who pays for energy suddenly have huge incentives to conserve it. There still remains no reason to have a conservation standard, because everyone is working hard on conserving it.

As it turns out, energy is dirt cheap, while the value from the internet is considerable. So I think the right balance is struck here with little to no interest in energy efficiency because there's little to no value to doing so.

    If you allow someone to pollute without charging them for it and the EPA, health insurance etc picks up the cost that is a subsidy to that industry.

    No, it's an externality, a cost imposed on a third party. Which is why it's called that. A subsidy is a payment or transfer of something of value usually to assist in a given activity.

    If the EPA deliberately paid for the harm caused by a business's pollution so that the business wouldn't have to pay for the externality itself (something the EPA doesn't do, BTW), then that could be a subsidy which also happens to be an externality.

    I have read a fair number of reports on natural gas fracking sites

    There's a lot of environmentalism oriented propaganda out there. I'm sure there is some truth to the claims of pollution and regulatory misconduct in there somewhere, but we need to keep in mind that fracking as well as any other major fossil fuel-based innovation is a huge threat to those who wish to end the use of fossil fuels (or even industrial society itself). And a lot of those people are willing to lie outrageously to get what they want.

    My view is that oil drilling has gone on for a long time. Even fracking as a technique has been used for decades. If there was a serious pollution problem with this stuff we would have seen it long ago with major air and water quality problems nowhere near an oil well.
