Yeah... 2W is just not that much energy.

Enough energy to run that thing for an entire year in under 1/2 a gallon of gasoline.

When you can pretty easily offset the entire yearly energy use by skipping a mow of your yard once, or even just driving slightly more conservatively for a few days... I'm not so worried about the power use.

In my region - it's about $3.50 in yearly power costs.
