RELATED ARTICLES Lighting and Phantom LoadsGarage Door Openers Are Always On What to do about itWaste can be sharply reduced at little or no cost, according to a companion “self-diagnosis and action guide.”The guide suggests how to find the devices that are wasting electricity, and several ways of calculating how much power is involved, either by measuring the household’s total idle load or measuring power consumption device by device with a Kill-A-Watt meter.To reduce idle loads, the report offers these ideas:Unplug devices that aren’t being used or are rarely used, such as a TV in a guest room or a spare refrigerator that’s currently empty.Plug devices into a power strip that can be switched off manually, or use an advanced power strip that automatically turns devices off when they’re not being used.Plug some devices into a timer.Adjust power settings. Set a computer, for example, so it goes to sleep after 30 minutes or less of inactivity. Or, disable the “instant on” feature on a game console if you don’t need it. The NRDC worked with Home Energy Analytics and the Stanford Sustainable Systems Lab to study three separate data sets: smart meter readouts from 70,000 homes in northern California, smart meter and other data from 2,750 San Francisco Bay area homes, and “a detailed in-home audit” of 10 Bay Area homes.The wasted energy collectively is roughly the output of 50 large (500 megawatt) power plants. On average, the “always on” electricity used by inactive devices represents nearly 23 percent of household electrical consumption in northern California homes, the report said. Electronic devices that use electricity even when they appear to be turned off, and a new generation of appliances with digital components and internet connectivity, together waste a total of $19 billion a year in electricity, according to a new report.“One reason for such high idle energy levels is that many previously purely mechanical devices have gone digital,” Pierre Delforge, author of the report and director of NRDC’s high-tech sector energy efficiency, said in a statement. “Appliances like washers, dryers, and fridges now have displays, electronic controls, and increasingly, even internet connectivity, for example. In many cases, they are using far more electricity than necessary.”The report, “Home Idle Load,” said that idle loads or “baseload” consumption includes appliances and equipment in “off” or “standby” mode that are still drawing some electricity; devices in “sleep mode” that are capable of powering up quickly; and equipment that’s left fully on even when no one is around to use it. UtilityDive said that the Natural Resources Defense Council study set the loss at $165 for an average household in the U.S., but said so-called “vampire energy drain” can cost a consumer as much as $440 a year.
Connectiv’s Business Information Network report is based on calculations of the size of the industry and aggregated data from several sources that report on revenues. Event revenue is supplied by CEI, print advertising data is supplied by IMS. B2B digital advertising revenues are estimated by Connectiv and based on information by IAB. Information on data is supplied by Outsell and supplemented by public information and Connectiv estimates. Revenues went up in the B2B media and information industry by 2.7 percent in 2015, according to the Connectiv Business Information Network report. Events account for the majority of revenue across the B2B media industry, with $12.65 billion dollars in revenue, up 3.7 percent. Overall, trends point to a new mix in revenue streams. Today, print accounts for 23 percent of all revenues, down from 33 percent in 2009. Source: Connectiv’s BIN Report Source: Connectiv’s BIN Report Matt Kinsman, VP of content and programming at Connectiv, wrote that he expects that most Connectiv members will self-classify as “business information services” rather than “business media” by 2020. Kinsman also expects paid content and data/information services to pick up speed moving forward. Meanwhile, digital advertising and data/business info have both steadily risen since 2009. Digital ads went from 10 percent of revenues in 2009 to 22 percent of revenues in 2015. Data went from 8 percent of revenues in 2009 to 11 percent of revenues in 2015. Year-over-year, digital advertising grew 17.4 percent, while data grew by 2.7 percent. The report credits growth in digital advertising/marketing, a steadily growing events industry and a rise in data and information services, for increased revenues to $28.35 billion in 2015, from $27.6 billion in 2014. Print and digital advertising are nearly tied, bringing in $6.4 billion and $6.3 billion respectively. However, this marks a steep decline from print advertising, which dropped 4.1 percent year-over-year. Print ads were worth $6.7 billion in 2014, down from $7.6 billion in 2009.Source: Connectiv’s BIN Report Connectiv reports that exceptions to this is trend can be seen in three of the 22 vertical categories: Architecture, healthcare and automotive publications all saw an increase in print advertising revenue.
Angela Lang/CNET In its fifth year, Amazon’s Prime Day kept up its record of breaking records. The 48-hour sale this week was the “largest shopping event in Amazon history” and “surpassed the previous Black Friday and Cyber Monday combined,” the company said Wednesday. Amazon didn’t disclose specific total sales figures. Additionally, Monday brought in more new Prime members than any previous day, and Tuesday brought in nearly as many, making them the two biggest days ever for member signups.Prime members bought more than 175 million items during the Prime Day stretch. Amazon also benefited from its regular promotion of its own devices, with “the biggest event ever” for these gadgets, when comparing two-day periods. Some of the biggest sellers worldwide were Amazon’s Echo Dot, Fire TV Stick with Alexa Voice Remote, and Fire TV Stick 4K with Alexa Voice Remote. Prime Day has attracted great attention worldwide, after starting as a much smaller sale in 2015. Now hundreds of other retailers join in the summer sale, and consumers tend to delay their purchasing in anticipation of Prime Day. Meanwhile, activists and unions this year used the occasion to stage protests and highlight their concerns about the world’s biggest online store, from working conditions in warehouses to climate issues to Amazon’s ties to the US Immigration and Customs Enforcement agency.

Amazon Fire TV Stick With Alexa Voice Remote See it 2 Comments The protests weren’t the only issues to mar Prime Day over the years. While this year’s event worked out smoothly, glitches to Amazon’s site and mobile app have previously hampered the sale. Last year’s event had a botched opening that served customers error pages instead of deals. Despite those problems, last year’s Prime Day also broke sales records.Because Amazon is still growing, this latest Prime Day sales record isn’t expected to hold for long, with Cyber Monday in November typically becoming Amazon’s biggest sales day each year. Unlike Prime Day, deals on that day are available to all shoppers, not just Prime members.As it usually does for big sales days, Amazon offered up a bunch of big statements about Prime Day — for instance, that a record number of Prime members shopped on Prime Day in the US this year. Some of the biggest sellers in the country were the LifeStraw Personal Water Filter, Instant Pot DUO60 and 23andMe Health + Ancestry kits.In the United Arab Emirates, a new addition to Prime Day, some best-sellers included Al Ain Bottled Water, Ariel Laundry Detergent and Fine Towel Tissue Roll.

Coffee prices are at a 13-month high in international markets, after rain hit world’s largest-producer Brazil, lifting share prices of Indian coffee companies on Wednesday. Tata Coffee was the biggest gainer at 6.21 percent on the BSE at around 2.30 p.m., followed by Tata Global Beverages and Bombay Burmah Trading Corporation. “In Brazil it is raining too much in the Arabica areas, and this is definitely causing quality concerns,” Reuters had quoted a European physical coffee trader as saying last Friday. An Indian coffee grower said heavy rainfall is bound to impact harvesting of coffee crop.”Rains at the time of harvest can damage the crop as the beans will fall off. As a result, Arabica prices have been looking up in the last few days. Also, one cannot wish away the effect of drought in Brazil earlier in the year. Hence, it may not turn out to be a bumper crop as projected but not a bad crop either,” the Economic Times quoted coffee grower Anil Bhandari as saying.On June 17, the US Department of Agriculture (USDA) had forecast world coffee production for 2016/17 to rise by 2.4 million bags from the previous year to 155.7 million bags (60 kg per bag). The estimate was based on Arabica output in Brazil increasing to about 60 percent of total production, neutralising lower Robusta production in the country, along with Vietnam, and Indonesia.Arabica and Robusta are two main categories of coffee worldwide. The Arabica crop determines global coffee prices.After factoring global consumption at 150.8 million bags, the USDA said exports from Indonesia, Vietnam, Brazil and India are likely to remain lower (than last year). India had exported 3.20 tonnes of coffee in 2015-16, up 13.39 percent from the previous fiscal.After from being the largest producer, Brazil is also the largest exporter of coffee.
Hulu wants to drive more customers to its ad-supported streaming package — lowering the official price from $7.99 to $5.99 per month — while it’s trying to turn a profit on the live-TV bundle with a price hike.Starting next month, Hulu With Live TV will increase by $5 per month, rising from $39.99 to $44.99 per month (a 12.5% increase). At the same time, the monthly price of Hulu’s ad-supported video-on-demand service is dropping by $2, as it seeks to grow advertising revenue. The ad-free VOD plan will remain unchanged, at $11.99 per month.Hulu’s new pricing will go into effect beginning Feb. 26 for new subscribers. For existing subscribers, the new prices will be reflected in their next billing cycle after Feb. 26.The changes come after Netflix last week raised U.S. streaming prices for all customers, including an 18% hike on its most popular plan, the Standard two-stream HD tier, from $10.99 to $12.99 per month. Hulu had been prepping the pricing adjustments for several months — but given the timing, the company is hoping its entry-level streaming plan looks like an even more attractive option against Netflix’s price increase. Popular on Variety Hulu claimed its subscriber base topped 25 million last year, with the service netting 8 million total new subs for 2018. It doesn’t spell out which plans those customers take, but a rep confirmed that the “majority” of Hulu customers are on the ad-supported VOD plan. In September 2018, Hulu touted hitting 1 million subscribers for the live-TV service.Why is Hulu dropping the price of its most popular plan — given that it’s continuing to lose money? The joint venture lost up to $440 million in the third quarter of 2018, more than double a loss of $207 million a year earlier, according to filings by its parent companies.At the cheaper price, Hulu has seen higher engagement and retention among subscribers. And by pricing the ad-supported tier lower than rivals like Netflix, Hulu hopes to amass an even bigger audience for its ad business: The company claimed ad revenue jumped more than 45% in 2018, to nearly $1.5 billion. In addition, Hulu has already run extensive promotions for the VOD plan with ads for $5.99 per month for the first 12 months (and even offered it for 99 cents per month over Black Friday), and is now setting that as standard price. Also note that Netflix raised the price of its entry-level Basic plan, which offers a single non-HD stream, from $7.99 to $8.99 per month.Meanwhile, the rationale is more straightforward for the price hike for Hulu With Live TV. After an initial land-grab to sign up cost-conscious TV subscribers at the $40 price point — amid aggressive competition from the likes of Dish’s Sling TV, YouTube TV, and AT&T’s DirecTV Now — Hulu needs to make the package profitable.Over the past year, Hulu has added nearly a dozen live TV channels to the bundle, including the CW, Discovery Channel, TLC, Animal Planet and ABC News. It now includes more than 60 channels, including local broadcast channels for ABC, CBS, NBC and Fox. CEO Randy Freer, speaking at a conference last month, claimed the company has been able to improve margins on the live TV product by 50% over the past year but he also acknowledged, “We all have to ultimately run a business that can be profitable.” Hulu’s rejiggered pricing strategy comes ahead of a change in ownership structure: Disney is set to take over 60% control of Hulu after absorbing 20th Century Fox’s stake, with Comcast retaining its 30% stake and AT&T’s WarnerMedia holding 10%. Disney CEO Bob Iger has said he wants to expand Hulu internationally and boost investments in original content.Hulu positioned the price changes as providing a greater range of choices to consumers. The service boasts an on-demand lineup of more than 85,000 TV episodes, more than any other U.S. streaming service, plus thousands of movies. In addition to current shows like “The Good Doctor,” “Killing Eve,” “This Is Us,” “Atlanta” and “Grown-ish,” all of Hulu’s packages include original series like “The Handmaid’s Tale,” “Marvel’s Runaways,” “Future Man” and “Castle Rock.” In addition, it has exclusive U.S. streaming rights to all seasons of TV series including “ER,” “Lost,” “King of the Hill,” “30 Rock,” “Family Guy,” “Seinfeld,” “South Park” and “Curious George.”“Hulu is giving TV fans what they want — choice, flexibility and control — in what they watch, how they watch and what they pay for the TV plan that best suits their needs,” the company said in a statement about the price changes. ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

Explore further Journal information: Chemistry of Materials Red, green, and blue QLEDs, with the applied voltages in the upper left corner. The green QLED has a luminance of 168,000 candelas per square meter, which is more than three times higher than the previous best QLED brightness. Image credit: Jeonghun Kwak, et al. ©2012 American Chemical Society In areas besides brightness, the QLEDs have also improved but still lag behind OLEDs. The new QLEDs’ efficiencies (7.3%, 5.8%, and 1.7% for red, green, and blue devices, respectively) improve over previous QLEDs, although OLEDs can have efficiencies of up to 20%. Another challenge for both QLEDs (and OLEDs to a lesser extent) is lifetime. Since the early research of the ’90s, QLED lifetimes have not improved past a few tens of hours, and they experience rapid deterioration within a few hours of operation. QLEDs with inverted structures, like those used here, can have half-lifetimes of up to 600 hours, compared with tens of thousands for OLEDs.Although QLEDs don’t match the performance of OLEDs, the engineers explain that QLEDs have a few potential advantages that make them worth investigating further.“The luminous efficiency of the best OLEDs (phosphorescent OLEDs) and inorganic LEDs are comparable, up to ~100 lm/W for white emission,” Changhee Lee said. “However, the efficiency of QLEDs is still way behind, about 10 times lower. The efficiency of red and green QLEDs reported in our paper is comparable to the efficiency of the best ‘fluorescent’ OLEDs, which use fluorescent organic dyes as emitters. Of course, the lifetime of QLEDs is much lower than OLEDs and inorganic LEDs at this time. The potential advantages of QLEDs are: (1) much narrower emission bandwidth (full width at half maximum ~30 nm compared with 60-80 nm of OLEDs), which means that QLEDs have more saturated and purer color than OLEDs; (2) easier tunability of emission colors in the entire visible range by simply controlling the particle size and shape with the same chemical composition for the QD; (3) and therefore the cost of emitters are much lower for QLEDs while organic phosphorescent emitters used for best OLEDs are very expensive.”Overall, the brightness, efficiency, lifetime, and low turn-on voltage of the new QLEDs suggest that the quantum dot devices could have promising applications as TV, computer, and phone displays as well as lighting devices. Since quantum dots can be printed as ink, these displays and devices could also benefit from low-cost production methods.“Our future plan is to further improve the efficiency and reliability of QLEDs, in particular, blue QLEDs,” Changhee Lee said. “In parallel, we will make a full-color active matrix QLED display using our improved RGB QLED technology. We will also work on developing Cd-free QLEDs because of environmental and safety concerns related with Cd. We recently reported InP QLEDs in Chemistry of Materials, but their efficiency is very low. Therefore, we will work on developing new precursors for InP QDs and improving the performance of Cd-free OLEDs.” (Phys.org) — While quantum dot-based light-emitting diodes (QLEDs) are not made of organic materials, they share many of the same advantages as organic LEDs (OLEDs). For instance, both QLEDs and OLEDs outshine semiconductor-based LEDs in terms of their greater flexibility, better color quality, and potential for lower cost since they can be fabricated using a simple process on a large-area substrate. But ever since the first QLEDs were demonstrated in the mid-’90s, about a decade after OLEDs, their performance has lagged behind OLEDs despite ongoing improvements. Now in a new study, a team of researchers from South Korea has designed and demonstrated QLEDs with an improved efficiency and unprecedented brightness that matches the brightness of today’s best fluorescent OLEDs.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. The research teams at Seoul National University, South Korea, led by Changhee Lee, Kookheon Char, and Seonghoon Lee, have published their study in a recent issue of Nano Letters.As the researchers explain in their study, the key to improving the brightness and efficiency of the QLEDs is improving the injection of current-carrying electrons and holes into the quantum dots. The more efficiently the electrodes can inject electrons and holes into the quantum dots, the more efficiently the device can emit light. Usually, the anode is made of indium tin oxide, whose transparency allows light to escape. But here, the researchers inverted the device by making the indium tin oxide the cathode with the help of zinc oxide nanoparticles as an electron transport layer, which performed charge carrier injection much more efficiently than before.“The most important cause of the low performance of QLEDs is the poor injection of holes into the quantum dots (QDs) from the anode and neighboring hole transport layer due to a huge potential energy barrier,” Changhee Lee told Phys.org. “Because of that, the electron-hole balance is not achieved, resulting in low quantum efficiency and low maximum brightness. Furthermore, the excess electrons or holes, which do not recombine in the QD layer and enter the neighboring organic hole-transport or electron-transport layers (HTL or ETL), can cause leakage current and device degradation, resulting in poor efficiency and stability. Therefore, good carrier injection is a key factor for realizing high-performance QLEDs.”By patterning different sized quantum dots on the layer of zinc oxide nanoparticles, the engineers could fabricate QLEDs of three different colors: red, green, and blue. Whereas previous QLED brightness levels were in the range of 10,000 candelas (cd) per m2, the new red QLED displayed a brightness of 23,000 cd/m2 and the green achieved a remarkable 218,000 cd/m2 – the highest ever for a QLED and comparable to the best OLEDs. The previous highest QLED brightness is 68,000 cd/m2, which was for a green QLED reported last year by Lei Qian, et al. The new blue QLED displayed a lower brightness of 2,000 cd/m2, but low blue performance has been one of the biggest disadvantages of both QLEDs and OLEDs.
