Thank you Peri, this clarifies things, at least for me.

I compared this before to regenerative braking.  On second thought, that 
wasn't so good. When you slow down your vehicle, you WANT to decrease its 
kinetic energy.  Regen turns (some of) the KE into electricity instead of 
heat.  That's a good thing.

But this is different.  You've explained why very well.
