This book presents smart energy management in the context of energy transition. It presents the motivation, impacts and challenges related to this hot topic. Then, it focuses on the use of techniques and tools based on artificial intelligence (AI) to solve the challenges related to this problem. A global diagram presenting the general principle of these techniques is presented. Then, these techniques are compared according to a set of criteria in order to show their advantages and disadvantages with respect to the conditions and constraints of intelligent energy management applications in the context of energy transition. Several examples are used throughout the white paper to illustrate the concepts and methods presented. An intelligent electrical network (smart grid¿SG) includes heterogeneous and distributed electricity production, transmission, distribution and consumption components. It is the next generation of electricity network able to manage electricity demand (consumption/production/distribution) in a sustainable, reliable and economical way taking into account the penetration of renewable energies (solar, wind, etc.). Therefore, a (SG) smart grid also includes an intelligent layer that analyzes the data provided by consumers as well as that collected from the production side in order to optimize consumption and production according to weather conditions, the profile and habits of the consumer. In addition, this system can improve the use of green energy through renewable energy penetration and demand response.

Presented with the Award of the Senate of the University of Bucharest for the most prestigious book in the field of Life and Earth Sciences, 2022-2023.This book aims to highlight the particular situation faced by certain hydropower companies by the fact that they cannot fulfil their contracts due to force majeure. The first part of this book will be an analysis of how water is used in electricity production. It is important to point out that all types of energy sources use water, to a different extent, of course, and that its spatial and temporal availability is very important. The focus will be on hydropower, presenting the current situation at the global level, and the effect of reducing the amounts of water in the river system.The second part is based on the presentation of the concept of force majeure and the ways of presenting and drafting it in a contract. Many disputes or the success of a contract depended heavily on the provisions of this article of the contract. Obviously, there are also situations in which the signatory parties abuse or are not protected by these provisions of force majeure. Starting from a few brief examples from the international level, we reach a wide discussion of the situation created in Romania, when the largest supplier of electricity produced on the basis of water terminates several contracts invoking force majeure. The manner in which the opinion of the parties involved is presented to the court is analyzed and presented in detail.
