ENERGY STORAGE AND ITS MANAGEMENT 2025
The energy used in transportation accounts for 40% of energy consumption in the domestic sector. For instance, rail transport is clearly underutilized in Spain, being an efficient and widely used energy option in the most advanced countries (Switzerland, Austria, Germany, France, USA, Canada...). The idea of this page is to present works that try to make this way of transportation even more efficient and, in particular, its use for transporting goods, increasing the electrification of this segment. You can find in this page technical data, studies, books, and information on many different levels on the subject, and diesel electric traction and power management in general. And their interaction with conventional Power Systems.
