The sharp increase of the overall data amount makes their access and processing harder. Data replication is a well known technique that helps to decrease access time and improve reliability. In the context of Cloud Databases, most of data replication strategies do not answer simultaneously to performance and provider's profit with an awareness on energy consumption. In this paper, we compare different data replication strategies. Some of them intend to reduce the overall energy consumption when others intend to maximize the profit. We highlight that very few data replication strategies Figure out simultaneously solutions for those issues even if there is a high demand from industries to reduce energy consumption and carbon footprint. We finally analyse why and how the race for profit and energy savings should be researched together.
