Land requirements for solar energy are low compared to other land uses. In addition, they are comparable to the existing built-up area. For example, in Japan and South Korea, 85% of the land used for agriculture would be replaced with solar power. Compared with bioenergy, solar requires significantly fewer land resources.
Another problem is the lack of infrastructure to support large-scale solar projects. If the land in question is in reality a biodiversity hotspot, spatial frictions may arise. In densely populated regions, solar power plant installations tend to occur on domestic land, on unmanaged forests, or on land suitable for other productive uses. These practices may disrupt ecosystems.
