Renewable Energy and the Regional Economy — New Inequalities Born of the Energy Transition
Analyzing regional disparities in renewable energy deployment and the structural impact on local economies. Reading the asymmetry of benefits and burdens.
What Is Happening
In fiscal year 2023, the share of Japan's electricity generated from renewable sources reached 22.9%. Approximately twelve years have passed since the introduction of the FIT (Feed-in Tariff, 固定価格買取制度). Led by solar power, installed capacity has expanded rapidly, and the shift in energy policy appears to be proceeding steadily.
When the aggregate figure is disaggregated by region, however, a different picture emerges.
Regional Imbalance in Renewable Energy Deployment
Regional Economic Effects
Structural Gap
- •RE-suitable areas in rural regions; consumption in urban areas
- •Profits captured by urban capital; costs borne by rural communities
- •Risk of entrenching 'energy colonialism' dynamics
Solar photovoltaic deployment is disproportionately concentrated in Kyushu — a region favored by sunshine conditions, low land costs, and (initially) available grid connection capacity. Wind power is concentrated in Tohoku and Hokkaido, driven by prevailing westerly winds and vast tracts of unused land. Geothermal power is clustered in Oita, Akita, and Iwate, entirely determined by geological conditions.
In other words, the locations best suited for renewable energy deployment and the locations where electricity is consumed do not structurally coincide. The Kanto region, which accounts for approximately 40% of national electricity consumption, offers limited suitability as a renewable energy deployment site. The mismatch between where renewable energy is generated and where it is used forms the structural foundation for a new form of regional inequality.
Background and Context
The "Asymmetry of Benefits" Created by FIT
The FIT system introduced in 2012 achieved an explosive expansion of renewable energy. Solar photovoltaic installed capacity grew to approximately seven times pre-system levels. By guaranteeing renewable energy operators a fixed purchase price for 20 years, the system dramatically reduced investment risk and lowered barriers to entry.
At the same time, however, FIT also generated the structural problem of "benefit leakage from host regions."
Large-scale solar installations (mega-solar) are, in many cases, operated by major EPC firms and investment funds headquartered in Tokyo or Osaka. Revenue from electricity sales is recorded at the operator's head office location, and what accrues locally is limited to modest land rents and fixed asset taxes. Construction work, too, is often led by major general contractors, with local construction firms participating only as subcontractors.
According to data from the Agency for Natural Resources and Energy, the cumulative surcharge under FIT reached approximately 2.7 trillion yen in fiscal year 2023. This burden is borne uniformly by electricity consumers nationwide through their electricity bills. The benefits of electricity sales, meanwhile, accrue to the operators and their shareholders. Regional land is used, electricity rates nationwide bear the cost, and urban capital reaps the returns. Some commentators have described this structure as "energy colonialism."
Transmission Lines as a Bottleneck
The geographic concentration of renewables has also laid bare the constraints of transmission infrastructure.
Within the Kyushu Electric Power service area, the rapid proliferation of solar power has made output curtailment (出力制御) — the practice of halting generation when power cannot be transmitted — a routine occurrence. In fiscal year 2023, curtailed output amounted to approximately 15% of annual generation. Roughly one-seventh of the energy produced was discarded.
A similar problem is intensifying in Hokkaido. The northern and eastern parts of the island, where wind power sites are concentrated, lack sufficient transmission capacity. The transmission line connecting Hokkaido and Honshu (北本連系線, Kitahon Interconnection) has a capacity of 900 MW — clearly insufficient relative to Hokkaido's renewable energy potential.
Expanding transmission line capacity requires enormous investment and long construction timelines. A plan exists for a submarine HVDC (high-voltage direct current) transmission line between Hokkaido and Tokyo with a capacity of 2 GW, but completion is projected for the late 2030s. As renewable deployment continues in the interim, curtailment is likely to expand further.
Here lies a contradiction. The government has set a target of 36–38% renewable energy share by 2030. Yet the development of transmission infrastructure is not keeping pace with the target. Even when renewables are built in optimal locations, if the electricity cannot be delivered to consumption centers, investments cannot be recovered.
Friction with Local Residents — Landscape and Environmental Concerns
The construction of renewable energy facilities has also generated conflicts with local communities.
Forest clearing for mega-solar installations, low-frequency noise and landscape impacts from wind turbines, concerns about geothermal development affecting hot spring resources. Renewable energy is promoted as "clean energy," but for residents near construction sites, these facilities also carry direct impacts on their living environment.
As of 2024, more than 200 municipalities have enacted their own regulatory ordinances governing mega-solar or wind power installations. Some have adopted regulations that amount to de facto construction bans. "Renewables are necessary, but not in our area" — the NIMBY (Not In My Back Yard) dynamic has manifested in energy policy as well.
Reading the Structure
Asking "Whose Benefit?"
The expansion of renewable energy is itself indispensable to the transition toward a decarbonized society. The problem is that the distribution of benefits and burdens is profoundly asymmetric.
An analysis of the structure reveals three asymmetries.
The first asymmetry: spatial. Renewable energy is produced in regional areas and consumed in cities. Benefits accrue to urban capital, while environmental burdens are borne by the regions.
The second asymmetry: temporal. The FIT purchase period spans 20 years, but the economic benefit to the host region is concentrated in the 2- to 3-year construction phase. Local employment during the operational period is extremely limited.
The third asymmetry: risk. The risk of output curtailment is nominally borne by generation operators, but the cost is ultimately passed on to consumers through the surcharge. The irreversible impacts on landscape and environment are borne permanently by local residents.
If this threefold asymmetry is left unaddressed, "renewable energy for the regions" risks replicating the same structure as past public works projects — external capital arrives, extracts the benefits, and leaves only the negative legacy behind.
Community-Led Energy as an Alternative
An alternative exists. Germany's Stadtwerke (市民エネルギー公社, municipal energy utilities) represent a model in which local residents invest, generate and sell electricity locally, and return the revenue to the community. In Germany, approximately 40% of renewable energy generation is operated by citizen- and community-led enterprises.
In Japan, too, community energy initiatives have begun — Aizu Electric Power (Fukushima Prefecture) and Miyama Smart Energy (Fukuoka Prefecture) among them. However, disparities in capital relative to major corporations, grid connection priority, and insufficient institutional support make scaling up far from straightforward.
The FIP (Feed-in Premium) system, which took effect in 2022, signaled a shift toward a market-linked remuneration structure. The transition from FIT to FIP advances the market integration of renewables, but for small- and medium-scale community operators, it also heightens revenue uncertainty. In institutional design, the distributional question — "who benefits from renewable energy?" — becomes all the more critical.
The energy transition is an irreversible trend. The question is whether that transition generates new inequalities or becomes a catalyst for regional economic revitalization. The answer lies in institutional design.
