The only one I'm aware of is Ecosia, which uses a substantial amount of the money generated through its search engine to fund tree planting (80% of surplus income according to Wikipedia). More information here: https://info.ecosia.org/what

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 ...

The Natural Resources Defense Council commissioned a study in late 2015 to understand the energy consumption from 4K TVs, titled The Big Picture: Ultra High-Definition Televisions Could Add $1 Billion to Viewers' Annual Electric Bills. While this doesn't exactly answer your question as regards the resolution of You-Tube videos, it gives some solid clues. ...

If you are asking about sustainability in general, I assume social aspects should be factored in. DuckDuckGo follows a number of principles linked to privacy and openness. They tend to use and promote free software (also via donating to them every year), and they do not "bubble" you (i.e. restrict your search results) or track your activity. Lilo is a ...

As LShaver and Gerrit also mentioned in their comments, an exact answer would depend on the scope and method of calculation. You've already mentioned you are only interested in the search itself so I guess this means you don't want to include (part of) the footprint of Google's servers, the web-indexing process, or information storage about your query. But ...

As far as I know there isn't a "really famous green social media network / plug-in" where lots of green-minded people hang out and where you can just select the ones that live close to you. It's probably easier (and perhaps also more efficient) to reach out to real-life groups and communities in your area. Nevertheless you can try the following: Nearby ...

According to a 2016 blog post by Backblaze, a (particular) 1.5TB HDD uses 3.4W when idle and 5.9W when operating. This gives a lower bound of 20 kWh / TB / year and an upper bound of 35 kWh / TB / year. These numbers are much closer to the low figure than the high one given in the question. We can also see that larger drives use proportionally less power ...

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 ...

Meetup.com has all sorts of groups with different interests, and I am sure you will find a nearby group that aligns with yours. It is designed to show you what is happening close to you. In a different manner, what I would call a "green" social network also relates to how it functions and the principles on which it was designed. I know you are asking ...

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 ...

Science Daily is a good one. It discusses new scientific articles in a way that is understandable for non-scientists and it provides a link to the original article so you can read it yourself. The site has quite a bit of interesting subtopics. Just to name a few: sustainability recycling and waste pollution global warming alternative fuels solar energy ...

Not much at all. Since we waste more electricity waiting for a page to load with your monitor on. You would probably reduce your environmental cost by reading faster and not staring at the screen to think - leaving your monitor off as much as possible. This may help regarding the over all cost Using a tablet to read and recharge the batteries with a ...
