3.2 The Concept of Energy

The units kWh and MWh are used more often in the context of producing
companies as well as in workaday life [Mü+2009, p. 68]. The common calculation
of the unit conversions is:
1 kW h = 3600 J = 0,001 MW h
To understand the basic correlations between the different forms of energy and
the energy usage in manufacturing systems, the relevant principals of thermodynamics will be explained subsequently. Following the first law of thermodynamics
(law of conversation of energy) energy in a closed system can be transformed
from one to another, but it can neither be created nor get lost [He2012, p. 26].
