Linear regressions predicting how much participants favored investment in energy-efficient technology and how much they valued three features of energy efficiency (reduced carbon emissions, foreign oil dependence, and energy costs) from the political ideology composite (centered: M = 3.76, SD = 1.42) and demographic controls

  • Unstandardized regression coefficients (with SE in parentheses) are reported. Ideology composite: Higher numbers indicate greater conservatism. Note: 31 participants were excluded from these analyses because they did not provide their income level (remaining n = 626). The results do not differ if these participants are included in the analyses.
