What are you saying? If one runs two computers, one is using less
electricity than two computers running on the same hardware.
VMs make use of existing components which are just powered because the
host has them connected.
If you look at your system stats you will see lots of idle time, why not
have a VM make use of that hard disk that's still spinning to do
something useful.
BTW, that air-con power bill is no joke. That's a serious overhead.
