5W * 24h/D * 30 D/M * 12M/Y = 43200 Wh, or 43.2KWh per year

If a KWh costs you:                     then 43.2KWh is:
        Massachusetts:  32c             $13.82
        California:             30c             $12.96
        Florida:                15c             $ 6.48
        Germany:                42c             $18.14
        Denmark:                37c             $15.98
        United Kingdom: 33c             $14.26

So you need between 25 and 75W of 24/7 power usage to get to
$100 US of savings in a year.

A spinning disk draws about 7W. An SSD draws about 0.05W when
asleep, 1.5W in "active idle", and up to 8W during writes.
