There are 3 websites I recommend visiting: Ethical Consumer This article scores 15 laptops brands on use of conflict minerals and toxic chemicals, worker rights, carbon reporting and tax avoidance. The manufacturer of Iameco is listed as a bad choice when it comes to use of conflict minerals and worker rights, but they do score well on use of toxic ...

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.

"To compare purely the electricity usage ... Desktops are clearly worse for the environment in this respect." — That certainly used to be the case, and still often is, but only because people buy/build systems that are overpowered. In 2019 it is possible to build a 'serious' desktop system that consumes very little power — provided you don't play the sort ...

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. ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

There are some differences began the situation for laptops and desktops, as well as some common solutions. Desktop machines obviously use more resources in manufacturing, and may use more electricity, but are more repairable and upgradable. My case and power supply are 17 years old, though most other components are newer. Upgrades to keep a machine working ...

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 ...

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.

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.

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 ...

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 ...

I thought a new development would be worth mentioning: CrowdSupply hosts a successful crowd-funding campaign for the EOMA68 line of computing devices. EOMA68 is a standard, and the computing devices have the benefit of using easily-replaceable parts to fix or upgrade them, 3D-printable casings, and components that can move from one casing to another (for ...

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, ...

The most sustainable hosting choice would use: 100% renewable energy energy-efficient servers properly recycle all hardware at the end of their lifespan Hosting at home You could consider hosting yourself at home and use electricity generated by your own solar panels. The solar.lowtechmagazine.com website does that for example. The advantage is that you ...

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-...

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.

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 ...

Inkjets are the Hummer of printers If you care about the environment, give that inkjet printer to the next person you can find for whom your gift/sale will prevent them from buying a new inkjet. Inkjet printers are planet-hateful products. They are built to be cheap, frequently replaced, throwaway items. Further, a huge amount of engineering goes into ...

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 ...
