This chapter shows that renewable energy penetration is necessary toward a low-carbon society and explores the justice issues arising from the renewables penetration. It highlights the negative impacts on local environments, which often lead to Not-In-My-Backyard (NIMBY) movements, but also points out that renewable energy is an important local resource to be utilized by local people. Zoning renewables promotion zones would mitigate the conflicts between renewables facilities and residents. This chapter also addresses the challenges of expanding nuclear energy post-Fukushima. The policies and schemes that prompt renewables such as feed-in tariff are analyzed. They benefit rich households but leave poor households struggle in expensive electricity bills. This structure leads to the energy justice problem.
