Public Acceptance of Renewable Energy Across 21 Countries: Public Attitudes, Community Consent, and Policy Design

Decarbonisation targets are now widely adopted. However, the speed at which renewables are built depends on many factors, including technology, cost, regulation, and the decisions of investors, developers, and governments. Public acceptance is one of these factors, but it is not the decisive one. This article examines public acceptance specifically: the attitudes, perceptions, and preferences of citizens and consumers, which form only one part of the wider social acceptance of renewable energy that also involves policy-makers, intermediaries, and market actors. We ask how public acceptance of renewable energy varies across countries, what drives that variation, and which policy instruments most reliably turn public approval into built capacity. Using a structured narrative synthesis across 21 countries, we integrate major cross-national opinion surveys (Eurobarometer 555, the UNDP–Oxford Peoples’ Climate Vote 2024, Pew, DESNZ, CSIRO, KfW, Ipsos), peer-reviewed work on local community acceptance, and capacity data from IRENA and the IEA. Three findings stand out. Headline support is high almost everywhere—a median of 76% across 77 countries and 85% in the EU—but increasingly masks polarisation, most sharply in the United States, where the partisan gap on prioritising renewables widened from 26 to 49 points between 2020 and 2024. Technology-specific acceptance follows a broadly consistent order, from rooftop solar down through wind, geothermal, hydropower, and biomass to carbon capture and nuclear. And community acceptance turns less on physical proximity to infrastructure than on procedural fairness, place attachment, and meaningful financial participation. Our contribution is integrative: we propose operational indicators of public acceptance that travel across national contexts, a country typology linking acceptance institutions to renewable outcomes, and a five-element policy architecture—early participation, benefit sharing, procedural transparency, place-sensitive siting, and credible information—each mapped to the acceptance dimension it addresses.
