Virtually all the energy used by a PC ends up as heat.
In NS, for >6 months of the year, the heat is not "waste".
It contributes to the overall heating for your home/office, and
should be subtracted from the cost of other heat sources.
In other words, compared to Silicon Valley, where for 6
months of the year you pay to remove the heat, the economics
of running a PC are much different.
There are other costs/benefits of heat -- most components age more rapidly,
so if the lower energy consumption allows you to keep the components
cooler, you benefit (at least statistically) from improved reliability.
Depending on the surroundings, noise from cooling fans can be a
plus or a minus.
