In this paper, I discuss how electricity supply systems should function in the future. The inability to restart nuclear power plants after the Great East Japan Earthquake created worries about power shortages in Japan. Nowadays, discussions on electricity supply systems are mired in confusion due to conflicting interests in Japan. This paper deals with issues organized into short term and long term topics. Currently, society in general is looking for one answer that will fulfill three key conditions: breaking away from nuclear power generation, preventing a rise in electricity costs, and reducing greenhouse gases. But I conclude there is no single answer that fulfills all of these conditions. I suggest that if we want to reduce the number of nuclear power stations, then we should accept a rise in electricity costs. And if we cannot accept a rise in electricity costs, then we have to resort to the use of nuclear power or continue contributing to greenhouse gas emissions. As is often said, “There is no such thing as a free lunch.”
