The topic of renewables and their effect on economies is widely discussed in the world. Are the methods which are used towards the transition adequate and how will these attempts affect the economies of countries which are undertaking a leading role in changing to renewables? Is it true that using renewables makes economies more competitive? Or is it just coincidence that most of the competitive countries are using more of them? These are the main questions that I want to answer, or give a clearer picture of, during the pages of my thesis, with an emphasis on Germany and its special law and policy concerning renewables.
