The Information and Communications Technology sector was estimated to be responsible for over 7% of the energy consumed in 2020, and this is only expected to increase in the coming years. Power consumption is currently the largest contributor to CO2 emissions in running software.
In this talk, we will explain how we, as computer scientists, can mitigate this problem. We will describe how we can measure and compare the power consumption of both web-based IT systems and individual programs, and provide examples of initial results. This will contribute to the development of more energy-efficient software by supporting future programmers with energy-aware programming languages, tools, and wider system models.
