Dear Stan,
I'm sorry if I upset you – I didn't mean to do that. I was just trying
to clarify the idea that it is common – by people other than yourself
– to completely confuse the two different concepts of energy and
power. That's why I referred to the ABC talk by someone who also
should clearly know the difference between the two concepts but in his
talk he chooses to bemuddle and befuddle them possibly in the mistaken
belief that this communicates with an average public audience.
Cheers,
Pat Naughtin

I believe I should be the last person accused of not distinguishing
between energy and power. There should be dozens of notes on this
subject on the USMA forum from me over the decades. Let me quote
myself from the recently published book "POWER HUNGRY" by Robert
Bryce. On page 38 he quotes me as follows:
..... defining energy and power. One of the best explanations I've
heard comes from Stan Jakuba....."Energy has many forms, such as
electricity, heat, work, kinetic energy, .... Energy can be
visualized as an amount of something. Power is the energy flow. ....
Energy is a sum. Power is a (time) rate. And rates are often more
telling than sums."
So, in the article in question, when I used the term energy combined
with another word, such as the e. rate, e. usage, e. consumption
(but NOT consumED), etc. it is, of course, power and I could use any
number of "joules per .... day, hour, fortnight,... second" to
express that. Being a rational person, I obviously select the
simplest and SI way - using the W.
The moral is - let's pay attention to the modifiers accompanying the
term energy. They determine whether those two words in combination
mean power or not. Example: Energy usage is power. Energy used is
energy.

Dear Stan,
Here is an example of a talk from the Australian Broadcasting
Commission (ABC) where the words 'energy' and 'power' are used more
or less interchangeably, the unit, watt, is used to imply an energy
unit, and the unit, joule, is not used at all even though this talk
is about the energy future of the Earth.
