Climate change impacts on renewable energy generation. A review of quantitative projections

Highlights: • The impacts of climate change on renewables make up a growing area of research. • Despite uncertainties, climate models are the most well-trusted method. • Comparing projections is complex due to scopes, methodologies and variables. • Hydro and solar are more frequently analysed than other technologies. • Main gaps are lack of economics assessments and projections in developing countries. -- Abstract: Research on climate change impacts on renewable energy is becoming increasingly relevant due to the vulnerability of the sector and to the continual development of methodologies and availability of data. Public and private decision-making needs specific research. However, many gaps still exist in certain geographical regions and technologies. Providing economic estimates with a value chain perspective are also missing from most papers. This paper addresses the most relevant studies that project quantitative estimates of climate change impacts on solar, wind, hydro and other renewable generation technologies. Summary tables of impacts and projections are provided so that researchers, governments and the private sector may have an accurate view of the state-of-the-art on this topic.
