I do say my car "travels speed". I say it "travels 60mph". Perhaps "travels
at 60mph" would be more correct, but I expect the units to disambiguate the sentence. Just like if I say a cable transmits 100watts, I expect the listener to understand that it is transmitting energy at the rate of 100J/s.
You can not transmit a rate you can not measure the quantity of anything in units of rate.
I don't know what you're saying here, as rates are measured
all the time. Do you measure constant current power supplies in amps? That seems like the only way to measure one. But an amp is a rate. Consider the term
transmission line. Whether you're talking about transmitting frequency, current, or power over one, they're all rates.
It is good to know the distinction between energy and power. But thinking in terms of, and measuring in rates is often useful and natural.
And I don't object to the term "consume", either. To consume is to "eat, ingest, buy, spend". Not "destroy". And the verb has context. Just like when I talk about consuming water, I don't mean that my body is
destroying water. I mean I'm taking it from the clean water reservoir and it's not available for someone else to use directly. In the case of consuming electrical energy, it's being used by a device to do some work, and now nobody else can use that energy for their own devices.
