What powers Smart Meter transmitters ?

So if you follow the money who does pay?

You don't pay any extra because you have a smart meter.  There are a thousand and one overheads: the losses in the transformer at the substation, the leakage across the insulators on the pylons when it rains, the resistance losses in the underground cables in the street etc.

It's always been like this, note that both the old rotary meter and the non-smart LCD meter each consume 2W, so your smart meter is no different.

If only it all actually worked. My Avro installed smart meters came with an IHD that cannot connect to the garage wall located meters from any point in the house the range is so poor.
So I put the IHD in the garage near the meters, fine. I can then connect the (Geo) IHD to my wifi and the cloud, fine.
The manufacturer has a decent phone app I can connect to the IHD via the cloud and it works, take readings, see energy, fine.
Then it falls apart. For some reason every night the IHD is sent a remote reset command that wipes out the settings put in so I have to go reconfigure it onto the wifi. Obviously I have given up.
Avro and Geo are 'aware' of the problem but seem inept to resolve it and can offer no timescale (or enthusiasm!). Hence the only advantage of smart meters on Avro (who can't even remote read them yet!), not having to go out to the spider farm meter cupboard in the cold to take readings, is defunct.
your move Avro!

Are you sure the "1PH 2W" isn't one phase, two wire?

The Landis+Gyr datasaheet says "<5W":

You're probably correct.  Bit daft of L+ G to use such an ambiguous abbreviation right next to 230V !

However, the main point remains valid, meters only consume a watt or two and they don't meter it, unlike the IHD, that will slightly increase youe bills if let plugged in.
