So unless you have a TV more than 9 yrs old then when "off" it consumes 0.5W or less, that means it takes 2000hrs to consume 1 unit of electric.  There are 8766 hrs in a yr of 365.25 days so that is 4.4 units per year or around £1.50 per year, ~0.5p/day, ~12.5p/mth.  In other words a couch potato probably spends more on the food needed for the effort of getting off the couch to walk to the TV wall switch than he/she saves in electric :-).

It's not "BS". Although manufacturers claim < 0.5W, I find when measuring devices in the real world, they can actually use more than this. Plus most people will have multiple devices. Plus they are not all TVs; some are microwaves or built in ovens fitted over 10 years ago. It all adds up.

Also, don't only think about yourself and how it can cut your costs. If all of the the UK's 28 million households could cut 20W background load on average, that would mean a 0.5 GW reduction, or 5-10% of typical CCGT power generation. That would in turn mean a reduction in CO2 emissions. It might also mean we stand a better chance of avoiding blackouts this winter. Please do your bit!

Also known as "approximately one generating unit at a CCGT station" - it's still useful, but don't get ahead of yourself on what impact it would actually have.

I thought they all had that sort of thing.  So some are basically just a hair-dryer in a box then?  Must be very profitable for those making them.

Yes, the 'ring' from an electric cooker mounted above the pull-out tray with a fan blowing air down over the ring and onto the food, so you have radiant and convection heating. 

I have one and it's good for food like Chinese Spring Rolls but I find it makes chicken pieces too dry.  

If they are too dry then you are leaving them in too long

I cooked a whole chicken in the air fryer yesterday, bottom up first, then turned it over after 30 minutes and give it a squirt of cooking spray, 30 minutes later came out perfect.

The only battle was trying to get the whole chicken into the air fryer
