I use an old laptop for my wallets and set the screen turn-off time when not being used to 5 minutes so it consumes hardly any power - maybe 20W-40W or so.
I like the idea of the PoS coins but this really gets ones goat up when people in the space bang on about energy waste and how PoW is demonised (not you MagicSmoker, but thanks for reminding me about this rant). This example is leaving a machine on round the clock to stake and consuming energy just for that purpose...
Really strange as its around half of what a 1060 can draw that full tilt mining (well on a light algo like phi etc you can go conservatively get under 80w) so in a nutshell not really saving the planet is it?
No, that's a really good point about running a computer just to keep wallets open for staking. My electricity costs $0.12/kw-hr so running that laptop costs me around $0.10 per day and I can guarantee you it isn't earning anywhere close to that from staking two different POS coins. Fortunately, I use the laptop to monitor my mining rigs as well so it would be running 24/7, anyway.
