Climate Integrate conducted an opinion survey on renewable energy* in Japan from September 4 to 7, 2025. The survey indicates that 70% of respondents see the need to expand the deployment of renewable energy. We hope that this survey will serve as a useful reference for policy discussions and local efforts to promote renewable energy.
* Renewable energy is energy produced by sources including solar, wind, or hydropower, and it can be used to generate electricity, heat, etc. The five types of renewable energy covered by our survey include solar, wind, hydro, geothermal, and biomass.
Survey Results – Highlights
- 84% of respondents view climate change as a serious issue, and this concern is widely shared.
- Over 90% are aware of renewable energy.
- 70% have a positive perception of renewable energy.
- 70% recognize the need to expand the deployment of renewable energy, while only 10% see no need for expansion.
- By power generation method, about 60% support renewable energy, while less than 40% support thermal (fossil fuel) and nuclear power generation.
Survey Results
1. Perceptions of climate change – severity
A full 84% of respondents view climate change as a critical issue, and this concern is widely shared.
2. Awareness of renewable energy
Public awareness of renewable energy exceeds 90%.
3. Public perceptions of renewable energy
A full 70% of respondents hold positive perceptions of renewable energy, while negative perceptions remain limited.
4. Need to expand renewables
Among those surveyed, 70% recognize the need to expand renewable energy, while only 10% feel there is no need to do so.
5. Support by power generation type
Renewable energy* enjoys about 60% support overall. In contrast, support is below 40% for both thermal (fossil fuel) and nuclear power, and nuclear has the highest level of opposition. (*Support for renewable energy is calculated from the combined support rates for the five types of renewable energy surveyed.)
