The Energy Saved By Ditching DVDs Could Power 200,000 Homes

Daniel_Stuckey (2647775) writes "The environmental benefits of streaming a movie (or downloading it) rather than purchasing a DVD are staggering, according to a new U.S. government study by researchers at the Lawrence Berkeley National Laboratory. If all DVDs purchased in 2011 were streamed instead, the energy savings would have been enough to meet the electricity demands of roughly 200,000 households. It would have cut roughly 2 billion kilograms of carbon emissions. According to the study, published in Environmental Research Letters, even when you take into account cloud storage, data servers, the streaming device, streaming uses much less energy than purchasing a DVD. If, like me, you're thinking, 'who buys DVDs anymore, anyways?', the answer is 'a lot of people.'" The linked paper is all there, too — not just an abstract and a paywall.

      Not that many people mail-ordered houses in those days, and even when they did, the USPS did not deliver it. We're talking about the USPS's business here. Look, youngster, I remember the 80s quite well, and mail order was not very common then. People ordered stuff once in a while, but this was a time when not everyone had credit cards, bank-issued Visa/MC debit/ATM cards did not exist, so paying for things usually meant a money order and waiting around hoping it would be delivered within a month. Fedex and UPS were not that large then either, as Fedex (or "Federal Express" as they were called then before they changed their name) actually concentrated on overnight deliveries, hence the "express". Later, in the late 80s/early 90s, mail order became more and more common, especially with people buying computer parts (anyone remember "Computer Shopper"?), and credit cards becoming more common with regular working-class people, but that's more recent; the 70s and 80s weren't like that. But even then, deliveries just weren't that common. Nowadays, people buy all kinds of stuff from Amazon and Ebay and Newegg and zillions of other online vendors. The USPS does a lot of business with small parcels; this simply wasn't the case 30+ years ago, or even 20 years ago.

      Hmmmm...

      We got several packages a month mail-order. When I was a kid in the 60's we lived on a farm in central Illinois. My parents and grandparents did a lot of catalog shopping. USPS used to deliver packages frequently. Big mail-order businesses at the time included Sears, Fingerhut (first catalog in 1948), Hammacher Schlemmer (first catalog in the 1800s), JC Penney, Montgomery Ward, Spirgel, and more. Most of these places had accounts, but you had several payment options.

      Most common method of ordering was to pull the order form from the catalog, fill in the items you wanted, calculate the costs yourself, and send it with a check. In those cases, often orders shipped once your check cleared the banks. In other cases, you could order and be billed later. Sometimes things came COD. Sometimes they came with a bill inside the package. Or a bill would arrive separately from the package. We did the same for ordering parts for some of the equipment, which wasn't available locally.

      Most mail-order companies had customer credit accounts, and you would just list your account number on the order form, or it might be pre-printed because the catalog was shipped directly to you. Some, like Fingerhut, used to put a peel-off mailing label on your catalog. It had account information printed right on it. You just pull it off the waxed backing, and stuck it right on the order form, which was inside the catalog. They would ship the order to you immediately, and you'd get a monthly bill. Some, like Penneys and Sears, offered their own credit cards, and you would just use their cards to order. A lot accepted Bankamericard (which became Visa).

      Every adult I knew had at least one credit card in the 60s. I think the most common were probably the gas company cards. Shell, Fina, Gulf, and the like, although there were plenty of bank cards floating around.

      Our normal mail carrier was a nice lady, and she drove her own car. Most days she drove a station wagon because she had so many packages to deliver to homes and farms along her route, but some days she drove a little car if she didn't have much to carry. I remember in the '70s when she got a new Jeep Cherokee and was so proud of it. The first day she drove it, she stopped to talk to Dad, and the back end was almost full of boxes for delivery. Around the holidays she would sometimes have to split her route up into thirds because of all the pre-holiday catalog shopping, and she would sometimes drive a full sized van.

      UPS didn't deliver out where we were at the time, too far out in the country until the 70's. It was "too far off their regular route." We were 3 miles from a small town, and 10 miles outside the nearest city. Go figure. If something came by UPS, my parents would have to drive into town to pick it up. I remember those rides quite well. Dad commented once that they probably couldn't afford to deliver outside town because they charged less than USPS did for delivery, and yet the companies that shipped by them didn't know that and therefore used them a lot. Mom was always making notes on the order forms to please ship by USPS (if there were no listed options) because UPS didn't deliver to us. IIRC, USPS had a 20-lb limit on parcels at the time, so larger stuff would have to ship by UPS.

      Dad sometimes would hand me a tool or parts catalog with a couple of pages and items marked, and have me fill out the order form. I think that was a test more than anything else, but I smile when I remember it.

      I can see where if you lived in town, and tended to only need stuff that was available at local stores and businesses, you wouldn't have needed to mail order stuff much, and you may not have needed or wanted a credit card. Also, it's pretty obvious that the traditional walking mailman wouldn't have capacity to carry parcels in his shoulder pack or on his tiny cart. I know my grandparents, who lived in the city, occasionally got parcels, and they were delivered by a driver, not by their regular mailman.

I was surprised to discover how many of the accoutrements of wealth were actually rented by the British nobility. They would borrow hunting horses from a livery stable, rent a (furnished) townhouse from a middle class landlord, rent books from paid lending libraries, and even rent their clothes. As I understand, this occurred because most of the wealth either came from quarterly rent checks out of the family estate (their tenant farmers were renters too) or from interest on perpetual bonds bought from the Royal Exchequer; so regular rental payments were much easier to budget for than large capital outlays. Renting many of their possessions was necessary for all but the ultra mega wealthy in Britain before the 20th century.

The reason why we bother is probably because nearly 8 years later it's still the highest quality you can buy, and it was miles better than any streaming format when blu-ray just came out. Even if in 6 years streaming will be in 50Mbit/s with better or comparable quality, then it still means we have had some 14 years where blu-ray was the best thing out there.

    I also found blu-rays to be often cheaper than digital offerings (e.g. many TV shows are cheaper on blu-ray than they are on iTunes).

    Further more, for a lot of countries (e.g. The Netherlands) download options for TV shows are incredibly limited. It's often impossible for those countries to stream from places like iTunes, Amazon or the Sony store. The number of shows offered on blu-ray is much larger and while blu-rays unfortunately can be region protected there are still more options to import.

  19. Technical expl. of harmonics, with car analogy by Overzeetop · · Score: 3, Funny

    It means, as the poster alluded to FREE ENERGY. Though, as he says - it's not - because then we would call him a quack. He's just implying that 100-102% efficiency is possible when you synchronize the frequency of your input power source to the harmonic frequency of your target power consumption or device.

    If you need a car analogy, it's like filling your gasoline tank in your car and marking down the mileage, and then checking to see how many miles you have gone when you fill up the next time. This is where the quantum effect also plays a role, because by simply never filling the tank all the way up, you'll get an infinite number of miles per gallon. Example: Fill tank at 12,400miles, partial fill 4 times, then complete fill of 8.26 gallons at 13,175 miles = (13,175-12,400)/8.26 = 93.8 miles per gallon. Once you fill up the tank and mark the mileage down, though, you've cut off your "harmonics" and you'll get a finite value. That's why it's not really "free energy" because to get free energy or over unity you would never be able fill up the car all the way. The longer you can go without completely filling the tank and triggering the measurement, the closer you are to matching the engine/gasoline fill harmonics. I've achieved well over 300mpg in my truck this way, but I've also got special magnets on my fuel line and installed an "open flow" regulator on the air intake, so there are other advantages which helped me achieve this which are unrelated to the harmonics.

    The same thing applies to power - whether it be lightbulbs or networking equipment or freely spinning bicycle wheels, though in an entirely different way.

One example is GMail and the assorted google services. So, while I understand your point about virtualization, cloud and virtualization are two very different and very distinct things.

    It means asset depreciation is much lower, so server churn is much lower (less carbon, less waste less garbage)

    It depends how you measure it. In a pure cpu-power-per-watt, 1U servers are way cheaper than an equivalent blade solution, easier to service, and will run cooler. They do take more space, but asset depreciation on a 50K blade cage vs 30K of 1U servers is bigger in the blades.

    every watt is consumed rather than dissipated as heat

    Well, its not, and this is one of the biggest fallacies of virtualization. It wildly varies according to the workload and your configuration. For small workloads, you may even spend more in hardware to provide proper virtualization than you had to pay for a metal solution. You do gain flexibility, and yes, when well done, you may take more advantage of your hardware, but this is not a novel concept. When possible, solutions like linux containers, solaris zones and freebsd jails allows at least some level of flexibility with a smaller execution footprint.
    And regarding usage... well, most cpu's even implement an instruction that internally halts the cpu if not in use. Cpu consumption varies according to the workload, and most of the specs mention max consumption, not average consumption. It may even happen that your beefier setup actually spends more power per vm than single dedicated servers.

    It means common parts for all servers which leads to less manufacturing waste.

    Yes, but is it cheaper? As an example, almost all industrial processes wastes copious amounts of water, when often more sofisticated and reusable replacements are available. But water is cheaper.
