Rounding Shlomi's figure of 4 yr^2 ~= 4*9.9225e14 s^2 to 4e15, and guessing
that the computer you'll be doing most of your pumpkinging on might weigh
perhaps 5 kg with a screen area of say 0.25 m^2 or so, your total energy
expenditure in Joules over those 4 yr^2 of pumpkinging should be only about

5 kg * 0.25 m^2 / 4e15 s^2  ~= 3.13e-16  J ,

which is nearly nine orders of magnitude less than the energy expended
during a typical flea jump [1].

So probably you shouldn't worry about the workload. :)

(Wait... what?)
