South Korea is rapidly scaling up its renewable energy ambitions, using the ongoing geopolitical tensions in the Middle East as a catalyst to fast-track its transition away from fossil fuels. The country, which relies on imports for over 90% of its energy needs, has identified its dependence on foreign oil—particularly shipments passing through the Strait of Hormuz—as a major vulnerability in the wake of the Iran conflict.
At the centre of this shift is an expanding solar power programme that is transforming rural communities while contributing to national energy goals. A notable example is a small farming village where a one-megawatt solar installation generates steady monthly income, funding welfare initiatives such as free communal meals, transportation services for elderly residents, and recreational facilities. The initiative, often referred to as a “solar income village” model, has not only improved infrastructure but also strengthened community bonds.
Encouraged by such successes, the government plans to significantly expand the programme. From around 150 such villages in previous years, the target is to scale up to 700 villages in 2026 and eventually reach 2,500 by 2030. This expansion is part of a broader policy push led by President Lee Jae Myung, who has repeatedly highlighted energy security as a national priority.
To support the transition, the government has allocated substantial financial resources. A supplementary budget includes approximately 500 billion won for renewable energy infrastructure, alongside an additional 400 billion won in low-interest loans aimed at supporting rural solar projects. These measures are expected to boost overall renewable energy investment to record levels and accelerate deployment across the country.
Despite this momentum, significant challenges threaten to slow progress. One of the most pressing issues is limited grid capacity, particularly in regions where solar and wind installations are concentrated. In some areas, renewable energy projects are unable to connect to the grid, resulting in wasted capacity. Infrastructure expansion, including the construction of high-voltage transmission lines, is also facing delays and resistance from local communities who feel they bear the burden of supplying electricity to urban centres without direct benefits.
Another major concern is the country’s reliance on imported solar components, especially from China, which dominates global manufacturing and offers lower costs. While the government is attempting to encourage domestic production and introduce carbon footprint standards for imports, critics argue that these steps may not be sufficient to reduce dependency.
Policy contradictions have also drawn criticism. While the government is investing in renewables, it continues to subsidise fossil fuel prices and delay the closure of some coal-fired power plants. Reports indicate that a much larger sum has been allocated to stabilising fossil fuel costs compared to renewable investments, raising concerns about the consistency of the transition strategy.
Experts say South Korea is at a critical juncture. While political intent and financial backing signal a clear commitment to renewable energy, the success of the transition will depend on resolving structural bottlenecks, aligning policies, and ensuring that investments translate into tangible outcomes. The coming years are likely to determine whether the country can turn its renewable ambitions into a lasting transformation of its energy system.
