The Environmental Impact of Broadcasting and Connected Digital Media

The speaker for the January 2014 meeting at The Tea Bar will be Janet West who is an Environmental Strategist and Lead Consultant at 7gen.   The subject for this month is "The environmental impact of broadcasting and connected digital media".

We are living in a world that is increasingly becoming “connected” from watching TV live or catch-up to social networks to banking. The talk addresses the connected world from the point of view of energy, resources, e-waste, employment, the psychological and physiological impacts and asks whether current business models are sustainable.   

Janet West has over twenty five years in the technology side of broadcasting particular in the development of HDTV. In 2007 she updated her environmental credentials and has since been lecturing in France and in the UK and at the BBC in Research and Development. She is now co-director of the environmental consulting company 7gen (

The Tea Bar will be open from around 6:30pm before the talk which starts at 7:30pm, so you can get yourself a drink and have a chat with other participants. The discussions will aim to finish around 9:00pm, though everyone will be welcome to stay around and have a chat with the speaker afterwards ... and indulge in more of the Tea Bar's delicious cakes.

The format of the evening is usually a talk of 30 to 40 minutes, followed by a short break so the audience can refill their glasses, before questions and discussions about the talk. Entry is free and open to everyone, but we do encourage you to buy a tea, coffee or drink (and cakes) at the bar to show your support for The Tea Bar who sponsor the meeting by providing the venue.

Cafe Scientifique is a place where, for the price of a cup of coffee or a glass of wine, anyone can come to explore and debate the latest ideas in science and technology.

    While I agreed with most of what Janet West said (largely we should consume less) I want to pick up on what I think, in the words of Radio 4's More or Less is a Zombie Statistic.

    The figure of 2 Google queries per kettle of boiled water comes from a Sunday Times report in 2009 (now hidden behind a paywall). The best summary of that I've found so far is

    Google's own figures ( are[masked]kWh per search. Using a 3kW electric kettle taking a couple of minutes to boil that's 3/30=0.1 kWh so about 300 searches per kettle-full.

    Moreover, if it takes me 15 seconds to read the results and my laptop is consuming 60W that's approximately the same as Google's consumption for my query. I've just turned my computer off....

    (Apologies for lack of references but the 1k limit prevents more detail)

      'More Or Less' is an excellent programme, which I recommend to anyone with an enquiring and sceptical mind. If you can't listen live it's available as a podcast (at only 0.001kWh per download ;-) ).
