BBC World Service — How Green is AI?

Generated on request by Bing Image Creator.

I heard the first part of this at 2:30 am this morning on the BBC World Service, then fell asleep. Pioneering computer scientist Sasha Luccioni has just been announced as one of the people on the BBC 100 Women list. She was talking with presenter Zoe Kleinman about the increasing amounts of energy being used by AI. 

The BBC World Service originally broadcast on shortwave in Europe, but transmissions on the SW bands ceased in 2008. It also broadcast to Britain on MW. It still broadcasts on 198 kHz LW when BBC Radio 4 closes down at 1:00 am. This was useful for anyone with a bedside radio having an LW band. I've been listening to it and Radio 4 on and off since the 80s. However with the amount of electronic gadgets in a house nowadays generating EMI, including chargers, burglar alarms and broadband modems, that's increasingly difficult because of the interference. However next year it's planned that transmission will cease on LW, so we'll have to listen using an app or Internet enabled radio.
