Abstract

Solar energy, with its declining costs and enhanced efficiency, is a viable alternative to traditional fossil fuels. However, its effectiveness is compromised by atmospheric and meteorological conditions, particularly air pollution, which reduces solar radiation and panel efficiency. This study estimates the impact of air pollution on solar photovoltaic (PV) power generation in South Korea, a rapidly industrializing nation with high levels of air pollution and a growing focus on renewable energy. Using hourly power generation data from 2006 to 2013 and addressing potential endogeneity of PM10 with an instrumental variable approach, we find that a 10 mg/m³ increase in PM10 reduces solar power generation by 2.17 MWh, resulting in an estimated annual economic loss of approximately USD 2.2 million during the study period. These findings highlight the urgent need to mitigate air pollution to enhance solar power efficiency and maximize the social benefits of renewable energy.

空气污染与太阳能光伏发电：来自韩国的证据

太阳能具有成本低、效率高的特点，是传统化石燃料的可行替代品。然而，大气和气象条件，特别是空气污染会降低太阳能辐射和太阳能电池板的效率，从而影响太阳能的有效性。这项研究估算了空气污染对韩国太阳能光伏发电的影响，韩国是一个快速工业化的国家，空气污染严重，而且越来越重视可再生能源。利用 2006 年至 2013 年的每小时发电量数据，并通过工具变量法解决 PM10 潜在的内生性问题，我们发现 PM10 每增加 10 毫克/立方米，太阳能发电量就会减少 2.17 兆瓦时，估计在研究期间每年会造成约 220 万美元的经济损失。这些发现突出表明，迫切需要减轻空气污染，以提高太阳能发电效率，最大限度地发挥可再生能源的社会效益。

期刊介绍： Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
