Hypothesis

The effectiveness of domestic development of renewable energy technologies varies across different contexts.

Conclusion

Renewable energy imports significantly reduce CO2 emissions, especially in regions with low renewable energy R&D investments.

Supporting Evidence

  • CO2 emissions are negatively affected by renewable energy imports.
  • Only in High-RERD and High-Emission regions can renewable energy R&D decrease CO2 emissions.
  • Countries with low CO2 emissions benefit more from importing renewable energy technologies.

Takeaway

Investing in renewable energy can help reduce pollution, but how much it helps depends on the country and its situation.

Methodology

Analyzed a panel dataset of 28 OECD countries from 2011 to 2020 using OLS, fixed-effects, and two-step system GMM methods.

Limitations

The study is limited to 28 OECD countries and the period from 2011 to 2020, and does not account for private sector R&D investments.
