This paper investigates the impact of k-anonymisation and dataset characteristics on energy consumption during machine learning (ML) training. Using three datasets from the UCI Machine Learning Repository, we analyze the energy ef􀀂ciency of ML algorithms—Random Forest (RF), k-Nearest neighbours (KNN), and Logistic Regression (LR)—trained on both kanonymised and original datasets. Our experiment reveals that kanonymisation signi􀀂cantly reduces energy consumption during Random Forest (RF) and Logistic Regression (LR) training. Additionally, we 􀀂nd that k-anonymisation leads to greater energy savings in Logistic Regression (LR) training if more features are present in the dataset. However, we also 􀀂nd that the energy savings do not hold in the KNN case, except for one feature case. These 􀀂ndings are backed by Aligned Ranked Transform Analysis of Variance on empirically measured energy consumption data. Our work strengthens the need for further empirical exploration into energy ","cbCaidoDNBGm3mRo","https://ap.wps.com/l/cbCaidoDNBGm3mRo","pdf",313961,1,11,"English","en",105,"# Abstract\n#
