1W of continuous power consumption is not great. To put it into perspective: that’s 1x24x365Wh, almost 9kWh per year. A kettle (1.8-2kW) can run for 4-5 hours for that amount of energy. If getting a kettle to boiling takes 5 minutes, that’s almost 50-60 kettles. That’s two month of boiling one kettle a day.

Or, at the rate of $0.30/kWh in California for residential use, $2.70/year. Lowering power usage on embedded devices is important when you're producing thousands, but for a hobbyist it doesn't really matter.
