Not always.

In cases you donate (or otherwise giving away without getting any reward back) your CPU resources you may choose to preserve them.

Modern CPUs have very broad range of wattage, so at in idle they consume around 3 Watts while at full load it may be 60 Watts, and then you see your donation directly hits your wallet with the electricity bill.

Note that "donation" may be non-consented, like e.g. with Skype messenger: it is a black box and it constantly consumes significant amounts of CPU cycles for some unknown background activities.
