Introduction

This chapter introduces the theme set by the question How can society convert to 100 percent renewable energy? Two important aspects must be considered. First, from a technical point of view, which technologies can we use and how can we design coherent and smart renewable energy solutions? Second, in terms of politics and social science, how can society implement such a technological change? The answer involves the formulation of the Choice Awareness theory, and this chapter formally defines the following concepts: choice awareness, radical technological change, applied and concrete economics, renewable energy, and smart energy systems. Finally, it discusses the term of sustainable energy versus renewable energy.
