ケーララ州パタナムティッタ県の家庭用エネルギー消費を、環境史の視点から1950〜2025年の四段階に区分して分析した研究。薪・農業残渣から電力・LPG、そして屋上太陽光へと移行する過程を、農村電化、湾岸移民、所得上昇、政府介入と関連づけて描く。転換は直線的ではなく、伝統的・近代的エネルギー源が重層的に併存したと論じる。
English
A historical-analytical study tracing household energy transitions in Pathanamthitta district, Kerala, across four phases from biomass (1950-80) to electrification, LPG, and rooftop solar (2015-25). It links the shift to rural electrification, Gulf migration, rising incomes, and government policy, arguing the transition was neither linear nor uniform but layered, with traditional and modern fuels coexisting.

日本のGX文脈において
日本のGX文脈への直接的な接続は弱いが、地方部の家庭用エネルギー転換と太陽光普及の長期過程は、日本の地域脱炭素・再エネ導入政策の歴史的参照として読める。
In the global GX context
Adds a Global South, environmental-history perspective to energy-transition scholarship, complementing techno-economic and disclosure-focused GX research with evidence on how households actually sequence and combine energy sources over decades.
👥 読者別の含意
🔬研究者:エネルギー転換を技術普及ではなく社会・環境関係の歴史的変容として捉える分析枠組みの一事例として参照できる。
🏛政策担当者:地方部での太陽光・LPG普及政策が家計の行動とどう相互作用するかの示唆を得られる。
📄 Abstract（原文）
Abstract Energy transitions have historically shaped the relationship between society, economy, technology, and the environment. In Kerala, household energy consumption has undergone a substantial transformation during the last seven decades, moving from dependence on traditional biomass resources such as firewood and agricultural residues towards electricity, liquefied petroleum gas (LPG), and renewable energy technologies. This transition was not simply a technological process but a broader socio-environmental transformation influenced by economic development, migration, changing lifestyles, public policy, technological accessibility, and growing environmental awareness. This paper examines the historical evolution of household energy consumption in Pathanamthitta district, Kerala, from an environmental history perspective. Using a historical-analytical approach and secondary sources including Census reports, Government of Kerala publications, Economic Reviews, renewable energy policy documents, reports of the Agency for New and Renewable Energy Research and Technology (ANERT), and relevant scholarly literature, the study traces four broad phases: the Biomass Era (1950–1980), the Electrification Era (1980–2000), the Clean Fuel Transition Era (2000–2015), and the Renewable Energy Era (2015–2025). Particular attention is given to the influence of rural electrification, Gulf migration, rising household incomes, LPG diffusion, government intervention, and the emergence of rooftop solar photovoltaic systems. The study argues that Pathanamthitta's household energy transition was neither linear nor uniform. Rather, successive energy systems overlapped, with households often combining traditional and modern sources. The transition from firewood to electricity and LPG altered domestic labour, household convenience, and indoor environmental conditions, while the emergence of solar energy introduced a new relationship in which households could participate directly in energy production. The experience of Pathanamthitta demonstrates how energy transitions can be understood as historical transformations in human-environment relationships and provides insights into the opportunities and challenges associated with sustainable household energy systems.
