*Time Rate* of energy consumption is power (J/s or W). *Time Rate* of energy production is power (J/s or W).
*Time Rate* is an essential part of these statements! ---- Original message ---- >Date: Wed, 27 May 2009 19:36:16 -0400 >From: "Stan Jakuba" <[email protected]> >Subject: [USMA:45113] Power or Energy? >To: "U.S. Metric Association" <[email protected]> >... > Energy consumption is power. > Energy production is power. >... *Time Rate* is missing from these two statements! *Time Rate* is *not* implied! Example: (symbols in italic) The energy E (or work) required to lift a book of mass m from the floor to the top of a table at height h is E = mgh, independent of the time taken for the lift. The time could be an interval of e.g. 5 seconds, 10 seconds, or more.
