In the past few weeks, our work investigating Internet demand and streaming has had a lot of attention in the media. This comes after our paper ‘Streaming, Multi-Screens and YouTube: The New (Unsustainable) Ways of Watching in the Home’ (authored by Kelly Widdicks, Mike Hazas, Oliver Bates and Adrian Friday) was published and presented by Kelly at the CHI Conference on Human Factors in Computing Systems this May.
The prominence of streaming, and the push for Internet infrastructure expansion to cope with the growth in demand, is important to consider due to the underlying energy impacts from the Internet infrastructure. Streaming accounts for perhaps 3% of global electricity demand, and is expected to grow further year-on-year. This growth is expected on broadband and fixed access networks, as well as mobile cellular networks (4G) which are particularly energy-intensive.
We investigated the prominence of streaming in everyday life through qualitative interview data with participants, alongside quantitative logs from wifi routers deployed into participants’ homes for one month. We uncovered new ways in which watching is becoming increasingly unsustainable, including: streaming is becoming the default way to watch, with broadcast TV access and DVDs becoming obsolete; and the increase in ‘multi-watching’, whereby households are simultaneously streaming content.
These findings gained an interest from the Environment Editor at the Sunday Times, Jonathan Leake. Through correspondence with Mike and Kelly, Jonathan wrote an article on our work ‘Energy used in streaming one film on Netflix makes 60 cuppas’. It was also picked up by Channel News in Australia and The Sun, among others. Following this, Kelly and Mike were interviewed by The Naked Scientists (article: ‘Video streaming habits affect electricity use’); the podcast created from this interview was aired on national radio BBC Radio 5 Live (Sunday 19th May) and ABC Australia Radio (Friday 24th May). Kelly and Mike participated in a live radio interview for BBC Radio Nottingham (aired the morning of Monday 20th May). And finally, we answered a list of written questions for IBC365, an online publication for the media and entertainment industry (article: `The real green screen: Is OTT putting pressure on the planet?’). We really enjoyed talking about our work to these wider audiences, and hope that awareness of the issue surrounding Internet demand will start to increase.

On Sunday Oliver Bates and Kathy New will be heading to the annual CHI conference to host a workshop on Responsible Innovation in the context of HCI research, practice and education.
Coming from research background that cares deeply about ethics, sustainability and designing technology that reduces negative impacts on the environmental and society we are particularly interested in engraining responsibility in terms of social and environmental factors at the core of HCI.
Towards an agenda for Responsible Innovation in HCI
In the School of Computing and Communications at Lancaster University, we are conducting a study into everyday use of the Internet, and how this might be shaped for the future.
The workshop will involve:
– Reflecting on your use of the Internet, particularly for watching, listening and social networking activities
– Discussing and designing solutions with other participants for adapting our use of the Internet
Please join us on Lancaster University campus (Science and Technology building A076) at one of the following times:
Friday 1st March 2019 9am-12pm or Monday 4th March 2019 6pm-9pm.
As a thank you for your time, a £10 Amazon voucher will be given to you.
Coffee, tea and biscuits will also be provided.
If you are interested in attending one of the workshop sessions, please contact the workshop organiser:
So, should there be limits to internet growth to halt it’s ever growing energy & carbon footprint, especially as we head further into IoT? Nice to see our limits2016 paper opinion piece picked up by tech radar and the IET, too.
There has been much interest in the Sharing Economy in recent years, accompanied with the hope that it will change and specifically make better use of existing resources. From a sustainability point of view, sharing of resources is good, surely? It could even be said that the Sharing Economy ought to align well with Computing within Limits and its underlying premises. In this paper with Daniel Pargman and Elina Eriksson at KTH, however, we take a critical stance and will elaborate on the intersection between the Sharing Economy and Limits.

Just shy of 1/3rd of our global carbon footprint is food related. Up to 1/3 of the food purchased in the developed world is wasted by the consumer. Approximately 60% of the adult population in the USA, UK and Australia is overweight or obese – with no signs of this trend decreasing.
Selection of low impact foods, available to discuss and eat during the workshop!
Check out our Food Design for sustainability workshop at DRS this year. Also, you can find the engagement cards and food impact data sheets we used and built on during the workshop.
Hi there, and welcome to the SDS group website. Our group has been under development for the last two years, and we’ve finally put a name and a website together. So, please take a look around and find out who we are and what we do.
We’ll be updating this site regularly with blog posts and research output, so come back soon!
