Conclusions

Writing this blog has changed my preset assumptions and ideas about renewable energies many different times. It is strange how educating oneself about a subject can sometimes give an even less clear vision.
Renewable energies are often hailed as the champions of our future systems. I believe that this statement is true but that the term "renewable energy" does not correspond to anything we have today. A renewable energy needs to be renewable in all senses, political, socially and financially as well. This challenge is what we, as a civilization, face today. An abrupt change needs to occur, a rupture in our way of thinking about energy. In the past there was Tesla and his self-acting engine, perhaps we need another one.
