Google Partners With Energy Companies to Let You Monitor Your Usage

Andy Salisbury — Fri, 22 May 2009 17:30:22 -0500

Google has long been an advocate of saving energy where possible, and now they’re bringing that same policy to their users with the recent introduction of the Google PowerMeter, a gadget that allows you to track your home’s power consumption.

The gadget will track your juice use by pulling information from your power company, just so long as it’s one of their partners. Their partners include: San Diego Gas & Electric (California), TXU Energy (Texas), JEA (Florida), Reliance Energy (India), Wisconsin Public Service Corporation (Wisconsin), White River Valley Electric Cooperative (Missouri), Toronto Hydro–Electric System Limited (Canada), and Glasgow EPB (Kentucky).

Currently the feature will only be handed out a small group of customers with each utility company, but this is purely for testing. They plan on making it more available once this process is taken care of.

If you’re interested in finding out more, be sure to check out the PowerMeter home page here.

Google: We're Friendlier For The Environment Than Cheeseburgers, Orange Juice

Andy Salisbury — Mon, 18 May 2009 16:36:08 -0500

Google recognizes that there’s been a lot of talk about the energy needed to power the Internet, and they’ve decided to publicly throw in their two cents by boldly stating that the carbon emissions required to get a glass of orange juice is equivalent to 1,050 Google searches.

“Our engineers crunched the numbers and found that an average query uses about 1 kJ of energy and emits about 0.2 grams of carbon dioxide,” wrote Urs Hölze, Google’s Senior Vice President of Operations. “We have a team of dedicated engineers focused on designing and building the most efficient data centers in the world. In fact, through efficiency innovations, we have managed to cut energy usage in our data centers by over 50 percent, so we're using less than half the energy to run our data centers as the industry average. This efficiency means that in the time it takes to do a Google search, your own personal computer will likely use more energy than we will use to answer your query.”

The blog post also noted that to do one load of dishes in an EnergyStar compliant dishwasher was equivalent to 5,100 searches, a give mile trip in the average U.S. automobile was 10,000 searches, a cheeseburger would run you 15,000 searches and just one month’s worth of electricity used by the average U.S. household clocks in with 3,100,000 searches. Sure makes you think, doesn’t it?

Maximum Green: 5 Freeware Apps That Save the Environment (And Your Cash!)

David Murphy — Mon, 27 Apr 2009 11:30:17 -0500

Green. It's all the rage in the technology world nowadays. You've got green hard drives. Green laptops. Green desktops. Green printers (with soy ink!). Green displays. Green power strips. Louis Armstrong saw skies of blue and clouds of white, but any geek worth his electric bill sees nothing but green. It's the color of the environment, and it's the color of all the cash you'll be saving by using green-themed applications to curtail your out-of-control PC habits. Or normal PC habits, because anyone can benefit from the open-source and freeware applications we're profiling in this week's software roundup. Best of all, most of these applications automatically take care of your green actions for you--set them up to run, and you won't have to lift a finger to tap into increased savings and Captain Planet-style goodwill.

Edison

What it does: This helpful little freeware application lets you establish schedules for "work time" and "non-work" time. From there, you tell the application what kind of energy-savings (and money savings) you want to achieve, and the application automatically calculates and sets the appropriate times for turning off your display, powering down your hard drive, and slapping your computer into standby mode after a certain span of inactivity. It's a basic, simple way to achieve energy-savings on your computer. Best of all, the application calculates out exactly how much money, energy, and carbon-dioxide you'll be saving. If that's not inspirational, we don't know what is.

LocalCooling

What it does: LocalCooling is the Maximum PC of energy-saving applications. Unlike Edison, LocalCooling performs a fairly thorough analysis of your PC's components to give you a rundown of how much power your supercharged rig is eating up. Once you've cried Mother Earth's tears, you can select one of three predefined power-saving options that, like Edison, set times for the automatic turn-off of your monitor, the spinning down of your hard drives, and the complete shutting down of your PC. You can also customize your own times if you want to take a more hands-on approach to reducing your energy footprint (and electric bill). Select your intervals and LocalCooling will estimate how much you could save!

NoSleepHD

What it does: Okay. We'll confess. This application is the complete antithesis of power-savings. But just in case you secretly harbor a deep dislike of your planet and/or have a wad of cash to blow for usability's sake, NoSleepHD is your ticket. This application runs in your system tray and keeps your hard drives--internal and external--from spinning down into sleep cycles. NoSleepHD presents a crude solution to the problem, as the program writes a super-tiny file to your drives at specific intervals to keep them spinning forever. But hey, it reduces those precious seconds of spin-up time to zero. Take that, Earth.

Magic Packet Sender

What it does: It's often tempting to leave the ol' computer on during the day so you can dial back into your home system from work to access your files, control your webcam, and download things that you shouldn't really be looking at during a typical 9-to-5 day. Yeah, that's right. But even if these scenarios don't fit your typical use, there's really no reason to leave your computer on during the day just because. If you use Wake-on-LAN functionality to turn your PC on remotely, then you'll want to use Magic Packet Sender to process the tiny commands you send home to turn the system on in the first place. And if you have no idea what Wake-on-LAN even is, well... download this application and take a read!

GreenPrint World Edition

What it does: You know what's annoying? When you're printing a Web page or a document, and all of your pages come out correctly save for the last one, which is usually just a small paragraph of unnecessary text, or a URL, or some miscellaneous element that wastes an entire page of paper. GreenPrint World Edition eliminates this frustration by scanning the documents you're about to print, then automatically removing these unimportant pages from the mix. And if you think that this issue is so miniscule as to not warrant attention or save any energy whatsoever, that's why this helpful application keeps track of all the wasted pages you would have printed without its guidance. And that's why we love it--an energy-saving procedure that backs up its usefulness with raw facts.

What's the Energy Cost of 62 Trillion Spam Emails?

Paul Lilly — Fri, 17 Apr 2009 09:59:07 -0500

Most of us view spam as an annoyance with the greatest cost associated with junk email being our time. However an even bigger price is being paid by the environment, a problem underscored by the startling amount of junk email that now flutters across the web. We're talking about 62 trillion spam messages in 2008 alone, according to a report released by McAfee.

In terms of the environment, McAfee researchers say each piece of junk email emits 0.3 grams of carbon dioxide (CO2), or a combined 17 million metric tons of CO2 for all spam-related emissions in 2008.

"The amount released into the atmosphere is significant," said Dave Marcus, director of security research for McAfee. "Spam has a big carbon footprint. It's something people be aware of."

Most of the spam-related greenhouse gas emission -- 80 percent -- comes from the energy used by PC users to view, delete, and sort for legitimate messages, McAfee says. The silver lining here is that by taking steps to reduce spam, you not only reclaim your inbox, but also can have a noticeable impact on the environment.

Solaren to Quench PG&E's Energy Thirst with Space-based Solar Power

Pulkit Chandna — Fri, 17 Apr 2009 09:54:45 -0500

California utility Pacific Gas & Electric has announced it will present its proposed agreement with Solaren Corp. in front of state regulators for ratification. PG&E plans to purchase 200 megawatts of space-based solar power from Solaren over the course of 15 years.

Solaren’s ambitious plan is to produce power by saddling a satellite with solar panels, which will collect solar energy and relay it to earth in form of radio frequency energy. Though space-based solar power was the figment of science fiction writer Isaac Asimov’s prolific mind, it is ready to make the transition to the real world.

Solaren expects to begin producing space-based solar power by 2016. If Solaren’s ambitious plan refuses to take off, the utility won’t suffer financially as it will only be required to pay for the power it receives.

"While a system of this scale and exact configuration has not been built, the underlying technology is very mature and is based on communications satellite technology. For over 45 years, satellites have collected solar energy in earth orbit via solar cells, and converted it to radio frequency energy for transmissions to earth receive stations. This is the same energy conversion process Solaren uses for its (space solar power) plant,” Solaren CEO Gary Spirnak said in an interview published on PG&E’s official blog.

German Towns Allow You to Control Streetlights With Your Phone

Andy Salisbury — Mon, 23 Feb 2009 14:06:50 -0600

If you find yourself in Morgenröthe-Rautenkranz, Germany late at night be sure that you’ve got your cell phone with you. In an attempt to save energy, the citizens of the town have set up their streetlights to turn off unless you use your cell phone to turn them on!

The program has been a moderate success so far. So far the town of only 900 has managed to save $5,300. Not too shabby! Other towns, such as Döblitz, resident Heinrich Frühauf tripped and fell in the darkness, and not long after the town was turning on their lights with cell phones as well.

Though, main issues with the program still remain. Many worry that this is just a gateway for corner cutting. Perhaps it might cause people to not use as much light as safety would require, causing for manhole accidents or night crime.

Google's PowerMeter Will Help You Conserve Power

Pulkit Chandna — Tue, 10 Feb 2009 18:28:45 -0600

Google’s prolific online search business not only allows it to invade other business niches, but also gives it the freedom to take up numerous social causes. Now the online search juggernaut has launched an online platform that will help ordinary people conserve energy.

The free tool, called PowerMeter, will allow users to view and thoroughly analyze their household energy consumption data. The platform, currently in closed beta, requires that the user possess a smart meter. It will let users compare the energy-appetite of different devices within their house, besides making it possible for users to compare each other’s energy consumption trends.

Google hopes that access to household energy data will help users conserve energy – something many studies and Lord Kelvin have previously suggested.

Researchers Claim New Solar Panel Can Collect 90% of Sunlight From Any Angle

Andy Salisbury — Wed, 05 Nov 2008 16:20:08 -0600

With some news straight out of the “didn’t we just hear about something like this?” file (we did), some groundbreaking research has revealed that a near perfect solar panel has been created.

Scientists at the Rensselaer Polytechnic Institute have allegedly found a process that allows them to trap nine out of ten photons that hit a solar panel, providing a 90 percent collection rate. A new anti-reflective coating for the panels provides grounds for creating solar panels that don’t have to change their angle in order to collect energy.

With current technology, the photon absorption rate stands at an already impressive 67.4 percent, with the variable of whether or not the sun is actually hitting the cells. But the new cells which according to Shawn-Yu Lin, the man responsible for the project, function like a “dense forest where sunlight is ‘captured’ between the trees.” This happens through a process that not only involves the new anti-reflective coating, but also the bending of the path of the sunlight to an angle that allows maximum capture of sunlight.

With all possible variables at their best, Lin claims that the cells can capture 96.21 percent of the photons that hit their surface.
