They've stated that they target 10W in the Air, the cooling system in the Pro is identical to the Intel so probably 28W ish, and the Mac Mini specs say maximum 150W continuous power, but that probably includes a few tens of watts of USB and peripherals.

2 port Pros usually have 15 watt parts and only a single fan. Of course, PL2 goes far above 15W.

M1 chip page shows that 10 watts is the thermal envelope for the Air

So I get the whole performance-per-watt spiel, but if they're targeting the same 10W as with Ice Lake Y-series[1], it's gonna be hot during continuous workloads like screen sharing, since they've seemingly decided to get rid of even the "chassis fan" they've had on 2019 Air.

Worth noting that Intel doesn't actually honor those 10W listings, and often boosts above it for significant portions of usage.
