3 3 Global Energy Management Program---- Business School. Definition Energy = capacity to do work

4 4 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Mechanical work –Thermal work –Electrical work

5 5 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Mechanical work = displacement of mass

6 6 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Mechanical work = displacement of mass displacement of mass = force x distance force x distance = (mass x acceleration) x distance e.g. (kg x m/s 2 ) x m = Newton x meter = joule

7 7 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Thermal work = displacement of atoms

8 8 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Thermal work = displacement of atoms atoms become agitated (i.e. move) when heat is applied e.g. 1 calorie = energy req’d to increase temp of 1 gram of water by 1ºC 1 calorie = 4.19 joules 1 joule = approx 0.25 calories

9 9 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Electrical work = displacement of electrons

10 10 Global Energy Management Program---- Business School. Definition Energy = capacity to do work Kinds of work: –Electrical work = displacement of electrons electrons may be induced by a magnetic field to travel through a circuit e.g. 1 joule can induce 1 amp through 1 ohm of resistance for 1 second

11 11 Global Energy Management Program---- Business School. Units of Energy joule (mechanical) –foot-pound –horsepower-hour (thermal) –British Thermal Unit (BTU) –therm –calorie (electrical) –kilowatt-hour
