Energy transitions refer to the process of shifting from one primary energy source to another. This often involves moving from fossil fuels, like coal and oil, to renewable sources such as solar and wind energy. These transitions are driven by the need to reduce greenhouse gas emissions and combat climate change, as well as to enhance energy security and sustainability. During an energy transition, various technologies and policies are implemented to support the change. This can include investing in energy efficiency, developing smart grids, and promoting electric vehicles. The goal is to create a more sustainable energy system that meets the needs of current and future generations.
