There are 3 websites I recommend visiting: Rankabrand.org This site rankes brands of all kinds of products, including electronics. Rankings are based on all information that can be found on a company's website and in their annual reports. Rankabrand assesses brands on their environmental performances, climate change efforts and labour conditions. If ...

An interesting question you pose. I'm writing my answer via a computer that is 7 years old and has been using GNU/Linux for 3 or 4 years. The battery or battery charger no longer works, but everything else does, and everything else is original. When I got this computer, new, it run Windows NT. After about 3 years it was virtually unusable due to the ...

Professional The low-carbon sector employees a lot of software developers. For example, wind farm operators use SCADA systems to provide data on performance and to inform proactive maintenance regimes; and wind-farm developers use modelling software to design the optimum layout of the windfarms. If you want to dedicate your career to it, and you don't have ...

Make sure your laptop is failing physically before deciding to buy new. It might just be that it's too old and worn to run Windows, but installing Linux might work. The easiest version to use is Linux Mint. See here for a guide: http://moderngreenlife.com/save-an-old-pc-from-landfill-with-linux-mint-xfce/ If you really have to buy one new, then spend a bit ...

Usually its around .5-10 Watts depending on the make/model/size etc. I would recommend getting a kill-a-watt meter and checking a variety of monitors to get a rough idea of the average. Then you could bring that up with regard to yearly savings. A 3 Watts average across 20 monitors per year is not nothing.

Making a difference with your web searches I'm a software developer myself, and one thing I do very often is use search engines. One small thing we can do for the environment is do searches with Ecosia, an organisation that donates 80% of surplus income to tree planting projects. There are add-ons for Firefox and Chrome to make it the default search engine. ...

Definitely YES. As currently supported versions of MS Windows (7,8,10) now will have problem to run on older machines with RAM under 500MB and CPU under old Intel Core2/CoreM, you can find plenty Linux distributions with equivalent functionality, which are supported and will run on even lover configurations. Therefore some platforms as RapsberyPi was ...

There is quite a lot of software that is in one way or another helping the environment. To give you an idea here are some categories: Environmental management systems to keep track of and analyze the environmental performance of a company. Life-cycle assessment software to investigate how exactly a product impacts the environment and what more ...

Not a full answer to your question, I do not know the footprint of the servers running the StackExchange sites, but it could be estimated from the information here. Good performance automatically means it uses as little resources (energy included) as possible. You could measure your own carbon footprint while using StackOverflow if you are using an UPS that ...

Unless you're into printing color photos, the laser printer is the way to go. The retail prices of toner cartridges may seem a bit steep, but there are ways to refill them. The toner lasts a long long time (a few thousand printed pages if you know what you're doing) and does not dry up, ever. Laser printers are efficient, very fast, and hardly ever break ...

That may be as easy as turning off the humidifier or blocking it from the room that the servers are in. If you've got a central heating system just blocking the vent(s) and returns for that and slightly opening a window will give you a slow transition. How much outside air you need depends on how many servers you have. Note that your next problem may well ...

I feel like the term 'sustainable choice' is pretty open here - sustainability is mostly a case of what we as a civilization want to devote limited resources to. In general, server farms are going to be a more efficient use of electricity than everyone hosting a site locally (even if that were technically feasible). And, for context, while server farms ...

Nowadays, a black or white background of websites doesn't matter much as a lot of people trashed their CRT screens already. LCD displays don't vary that much in energy consumption of dark or light colours. Anyway, to answer your question: No, or at least: difficult. Why is that? Because today not the computer receiving the website is the huge power ...

While you may not be able to get them refilled yourself, HP does run a recycling program for them, free of charge: HP Product Return and Recycling. Didn't look in to whether they simply refill and resell them or if they actually melt the cartridges down and start from scratch... either way it's better than the landfill. Unfortunately, you're still stuck ...

In fact there is an actual increase in energy consumption, though not much. What is done at the end devices is one thing (the encoding-decoding part). This answer from stackoverflow provides a good example: When Google switched Gmail to use HTTPS, no additional resources were required; no network hardware, no new hosts. It only increased CPU load by ...

I will address just a tiny part of your (great) question. It seems to me that a key factor is the simple fact that Microsoft is a huge corporation, who delivers a software used by hundreds of millions of computers, tablets, smartphones. It's deeply entangled with a whole industry based on fashion, software/hardware obsolescence, status symbols. It's ...

Just buy a used USB cable. You can go to a computer recycler and they will have thousands.

Develop for old hardware You could develop for old hardware or in general develop software that enables durable hardware. For example some developers provide slick Linux distributions like WattOS, others develop specialized tools that free up space on your Android phone (eg Audio cleanup, Ccleaner, etc) such that older hardware may serve longer. I think ...

The question seems to be asking only about the environmental impact of the cartridges, so I probably shouldn't talk about how a laser printers use 100 times more power while they are printing, but allow me just to say that for the whole life cycle the most significant stage for both types is paper usage, followed by the manufacturing of the product and ...

I have been using a CISS (Continuous Ink Supply System) for some time on my Epson RX610. Purchased through eBay it is a cheap investment. Be aware of the following regarding inks: the most important part of the whole printing system is really the quality of the inks and not so much the hardware Occasionally the printer "Cannot recognise" the non-genuine ink ...

There are some printers which are compatible with a Continuous Ink System. Today I bought one of these for my printer, so I can't tell you right know if this system works or not. I don't want to make publicity for a particular product, but I think if you google a bit you will find some stores and see in which printers this can be used.

Monitors typically have 3 power levels: On -- you're looking at one. Standby -- screen is black, but the electronics are active. Sleep -- circuits are off except for a small one to monitor the line to the computer Off -- it turns into a fancy cookie tray. I'm using a Dell U2412 21" monitor. I went to their web site and looked up the specs. Max 72 watts, ...

Here's a back-of-the-envelope calculation: This page describes the architecture of the Stack Exchange network. It consists of: 9 web servers 4 sql servers 2 redis servers 3 tag servers 3 elasticsearch servers 2 haproxy servers So that's 23 servers in total. Not all servers are equal, but since we do not have exact energy consumption figures we will use an ...

AFAIK there hasn't been much research on this topic, at least not about energy consumption of encryption on a global scale. Most research I've seen is concerned with the impact of specific types of encryption on the battery life of wireless devices (e.g. this article or this article) Estimates are that the ICT sector is responsible for around 0.6% of the ...

Summary: storing music locally most likely uses a bit less energy than streaming music, but it depends on things like if you replay the same song multiple times and if the music streaming service caches data on your device for reuse. You also need to consider how much of the used energy is green and here there are big differences between music streaming ...

There are many different things you can do to get active for your environment. Imho developers are even more important, as they create software that will consume energy at the design, development and later a lot more if it is getting used from many others. But next to this you can also change something on your behavior when you work, while using other ...

Always try to buy hardware, that is easy to repair and upgrade. This will save you from throwing it away to buy another one, when it breaks, starts to overheat due to dust in the fan or needs more memory, new hard drive etc. IFixit has a ranking of "repairability", that is really useful.

There are plenty of sites selling reconditioned laptops or second hand laptops. Some companies upgrade regularly and this releases perfectly serviceable computers to the public. These surely have better credentials for sustainability than a new eco laptop. I won't link to sites to avoid providing advertising but I must have purchased three laptops in this ...
