Generating Energy-Efficient Source Code by Refactoring

The increasing number of mobile devices, like smartphones and tablets, in households and industry is partly responsible for the increasing energy consumption. Meanwhile, the energy consumption for ICT exceeds 10 % of the total energy consumption in Germany. This 10 % can be categorized as households, industry, server and data centers, and mobile devices. The category mobile devices represent 11,6 % of the 10 %, so that it is the fourth biggest energy consumer of ICT. Thereby, the energy consumption of mobile devices accounts approximately 1 % of the German energy consumption. Furthermore, the prognosis for sale of mobile devices is positive and increases every year. On account of high energy consumption and demand of mobile devices, it is important to improve the energy-efficiency in this area to reduce energy costs for users and to save the environment.
