So the BBC recognise that listeners use a television, computers and other devices with screens to listen to radio programmes. Instead of being alarmed about how this will affect total UK carbon emissions which we must reduce by at least 80% by 2050, the BBC plans to use any available screen space to provide programme visualisations.
Wake up BBC, watch your own programmes on climate change. Instead of enhancing the listeners' experience, what about enhancing the experience of subsistent farmers in Africa and elsewhere who already suffering from the early stages of climate change.
If the BBC wants listeners to visualize something, imagine the 20 Million tonnes of CO2 emissions pumped out by Drax power station every year.
Computers use anything from 20 to 150 watts, flat screen televisions start at about 100 watts whereas many old analogue radios use less than 1 watt.
No doubt that the BBC will argue that they are only making use of a device that is already switched on. However at 8AM in the morning, most people hopefully don't have any computer switched on. Some people will now switch on their computers to follow Chris Moyles's programme and that's exactly the kind of habit that the BBC must not encourage.
I am running my own visualisation trial. Listening to TV programmes on my stereo via the freeview decoder, I have discovered that the visual part of many news programmes and documentaries does enhance the viewer's experience but far less than I had expected.
If the listener's device has a screen, BBC Radio needs only put up one message, 'Please use an analogue radio next time'.
