As a consequence, a disruptive transformation in the world energy system is expected, accelerating the decarbonisation of the world economy and the large-scale implementation of clean, eminently renewable technologies, whether existing or new. The search for a compromise solution between the several objectives of socioeconomic development and the climate, often conflicting with each other, becomes even more relevant in developing countries, where a very high growth in the consumption of electricity and increase of generation and transmission installed capacity is expected, which should be carried out as efficiently as possible.
Another aspect to emphasize concerns the interdependence nexus between energy and water.
The IEA also estimates that, in line with economic and population growth, global demand for energy and water will increase, doubling by In addition, climate change could exacerbate water stress in many regions of the world. The nexus water and energy then becomes a critical component of mitigation and adaptation strategies, especially in Brazil, due to the predominance of hydroelectric generation. In the case of Brazil, the electricity mix is marked by the majority contribution of renewable sources, in particular hydropower. Hydroelectricity promotes a number of benefits, including those related to the mitigation of climate change through low greenhouse gas emissions.

Also, when hydroelectric facilities incorporate regularization reservoirs, they may contribute to mitigating the vulnerability of the electrical systems in which they are inserted and to increase the resilience of surrounding ecosystems and communities, as well as their ability to adapt to the risks posed by possible changes in climate variables.
Nevertheless, its preponderant participation in the Brazilian electricity mix makes it more dependent on the climatic conditions and the hydrological regimes of the current and future Brazilian hydrographic basins. Since its foundation, CEPEL has developed and maintained in the state of the art an integrated chain of methodologies and computational models for the energy area, based on optimization and simulation techniques, also considering uncertainties. This chain of models has oriented the expansion and operation of the Brazilian electricity system on a sustainable basis, with a high share of renewable sources, such as hydroelectric and biomass, and more recently, wind and solar.
Due to its intrinsic nature, it has also contributed to the elaboration of mitigation actions, especially those related to strategies to implement low carbon technologies, with the consequent reduction of greenhouse gas emissions.
