Republicans and Democrats differ in why they support renewable energy

Americans strongly support policies aimed at increasing the use of renewable energy. Prior research has found that, overall, support for renewable energy tends to be motivated primarily by people's perceptions that it creates economic benefits and reduces environmental harms. However, the extant research has not established how these motivations vary across political segments. Here we investigate (a) if and how Republicans and Democrats differ in their stated motivations for supporting a transition to renewable energy, and (b) what demographic and attitudinal variables best predict Republicans' and Democrats' support for renewable energy policies. Using a nationally representative sample of American registered voters, we found a consistent pattern across multiple methods of analysis: Republicans' (compared to Democrats') support for renewable energy is driven more by considerations of economic costs/benefits, whereas Democrats' (compared to Republicans') support is driven more by concern about global warming. These partisan differences hold significant implications for those who seek to effectively tailor policy and strategic communication to these political segments.
