Some attributes\u2014such as support for higher RPS targets, reductions in water use, and preferences for online smart\u2011meter information\u2014remain relatively stable over time. In contrast, others shift considerably: WTP for increasing the \u003Cstrong\u003Erooftop solar share\u003C\/strong\u003E declines by more than 40%, while WTP to \u003Cstrong\u003Eprotect monthly credit banking\u003C\/strong\u003E rises more than 200%, reflecting heightened awareness of net\u2011metering debates and rapid growth in rooftop solar adoption.\u003C\/p\u003E\u003Cp\u003EImportantly, the study reveals that \u003Cstrong\u003Eenvironmental attitudes\u003C\/strong\u003E, measured through New Ecological Paradigm (NEP) scores, once strongly predicted preferences for rooftop solar and smart\u2011meter technologies in 2017, but these relationships fade or even reverse by 2023\u2014signaling a shift as these technologies transition from niche, identity\u2011driven goods to mainstream infrastructure. Meanwhile, environmental attitudes continue to robustly shape preferences for RPS increases and water\u2011use reductions in both survey waves.\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/epicenter.energy.gatech.edu\/2026\/03\/11\/temporal-stability-of-consumer-preferences-for-solar-energy\/\u0022\u003ERead Full Story on the EPIcenter Webpage\u003C\/a\u003E\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EA new study by EPIcenter affiliate \u003Cstrong\u003EJamal Mamkhezri\u003C\/strong\u003E examines how public preferences for solar\u2011energy policy have shifted over a six\u2011year period in New Mexico, offering one of the first long\u2011term repeated cross\u2011section analyses of willingness to pay (WTP) for renewable\u2011energy attributes.
