Which power markets are most attractive for renewable investment?

The global renewable market attractiveness cards are being reshuffled amid significant trade, regulation and energy policy shifts.

Our 2025 renewable attractiveness rankings show the Asia-Pacific region tightening its grip on the top 10 leaderboard, with five of the top 10 markets by attractiveness from the region. This compares to four markets last year, with Taiwan capitalizing on an above-average ease-of-business environment, jumping from #12 to #9.

Asia-Pacific’s overall gain as a region year-over-year came at the expense of Europe, which fell from three to two markets annually. The United Kingdom, hampered by significant internal grid constraints, which impact the deployment of renewables, notably north-south transmission bottlenecks, dropped out of the top 10.

The US, meanwhile, lost its attractiveness crown, primarily due to shifting energy priorities during the first few months of the second Trump administration — including the accelerated phaseout of key renewable development incentives from the Inflation Reduction Act of 2022, following the signing into law of the budget bill known as the One Big Beautiful Bill Act on July 4, 2025.

Australia claimed the top spot this year, rising from #3 in 2024, driven by robust solar photovoltaic adoption momentum — Australia is endowed with particularly high-quality solar resources — and continued support from federal and state authorities.

About the report and methodology:
The 2025 update to the annual Global Renewable Market Attractiveness Rankings provides an in-depth analysis of 37 power markets worldwide, comparing them using an integrated methodology comprising 18 scoring parameters, including Accommodation, Regulation, Profitability, Market Size, Fundamentals, Ease of Business, and Competition. The scores and associated commentaries were developed by over 20 regional power analysts based in 15 countries, in collaboration with a coordinating global team. In addition to measures of attractiveness across renewable generation technologies, technology-specific scores are available for utility-scale solar PV, as well as onshore and offshore wind.
