S ustainable E nergy S cience and E ngineering C enter Energy and Power Energy (in joules) = Force (in newtons) x Distance (in meters) Power (in watt) = Rate at which energy is converted from one form to the other ( in joules per second) Example: 100 watt light bulb is converting 100 joules of energy into light each second Power used in a given period is generally used as a measure of energy - kWh 1 kWh = 1000 x 3600 = 3.6 x 10 6 Joules (i.e. 3.6 MJ) 1 Million tonnes of oil equivalent (Mtoe) = 41.9 x 10 15 Joules (i.e. 41.9 PJ) kWh= kW x capacity factor x 365 x 24 - Annual conversion Exa - 10 18 ; Peta - 10 15 ; Tera - 10 12 ; Giga - 10 9 ; Mega - 10 6 1 TW = 31.54 EJ/year Useful conversion tables at: http://cdiac.ornl.gov/pns/convert.html
