All electric generation systems “waste” energy since none are 100% efficient. Of course of the electricity generated none is really wasted because the systems only generate what is being used. That is unless they have a battery or other method for storing the electricity. Some would say that a portion of the energy is wasted due to losses in transmitting the electricity from the generator to the user. That is really not wasted energy but rather part of the “price” to deliver the electricity to the point of use.
At the moment, there is no perpetual motion machine therefore energy is wasted in any way and therefore more sources of its energy are needed. I am working on developing new proposals for improving trains. While we are trying to develop a solar-powered train, we already pre-ordered them on the website https://www.aiper.com/ where we were even promised to make a discount. I believe that this is generally the best site in the field of energy sources, because they are responsible for quality and productivity there. I advise everyone to purchase, the site is really the best
