The Clash of Solar Energy and Agriculture: Finding a Path to Coexistence

Recently, the spread of solar power plants has raised serious issues regarding coexistence with agriculture. The installation of solar panels is threatening food security, and while agrivoltaics is proposed as a solution, it is mired in controversy over economic viability and efficiency. This blog post explores the responses from various countries and the potential for agrivoltaic technology.

As solar power generation rapidly increases worldwide, the issue of coexistence with agriculture has emerged as a significant concern. There are growing fears that the installation of solar panels on farmland could jeopardize food security, leading several countries to enact regulatory laws. France has established a law that prohibits solar panels from covering more than 40% of agricultural land, and the Italian government has issued an emergency order banning farmers from leasing their land to solar developers. Italian Prime Minister Giorgia Meloni has stated that solar panels pose a threat to food sovereignty.

Similar tensions have arisen in other European countries, including the UK, Spain, and the Netherlands, where solar developers typically attempt to install panels on land that is not used for agriculture. However, recent surveys from Bloomberg indicate that many developers expect most future business opportunities to come from installing solar on agricultural land, intensifying the conflict between agriculture and solar energy.

In the United States, conflicts between state and local governments are becoming more pronounced. Legislation has passed allowing state governments to have the final say over renewable energy projects, which means local communities may have little recourse if they oppose solar installations. This situation has both positive and negative impacts on the local community.

In response, agrivoltaic technology is gaining attention as a solution. This technology allows for simultaneous crop cultivation and solar energy production, potentially improving agricultural productivity and solar power efficiency. For example, some agrivoltaic panels can rotate to directly illuminate crops with sunlight, and such technology is already being successfully implemented in several areas.

However, concerns about the economic viability of agrivoltaics remain. Issues like rising costs from panel installation and decreasing agricultural productivity have been raised. According to U.S. government estimates, only about 1% of solar power is produced in agrivoltaic facilities, making it challenging to meet the cost requirements of solar developers. In particular, raising the height of solar panels is essential but leads to increased costs.

The issue of coexistence between solar power generation and agriculture will remain a critical topic in the future. It is essential for governments and academia to collaborate in advancing agrivoltaic technology to achieve sustainable energy production while ensuring food security. Future research and technological development are expected to play a significant role in resolving these challenges.
