This peer‑reviewed paper by Ong et al. estimates land-use intensity across technologies. It reports median land-use intensities (in m² per MWh) with nuclear at the low end and wind and solar significantly higher when total facility area is counted. The authors find that, depending on assumptions, "renewable power plants such as wind and solar can require one to two orders of magnitude more land than nuclear" per unit of electricity, and they stress that co‑use of land at wind farms complicates simple multiples like "x-times more land."

The study defines land-use intensity as "area per unit of energy production, or more specifically, the number of hectares per terawatt-hour of electricity generation in a given year." It reports: "Nuclear had the lowest median land-use intensity at **7.1 ha/TWh/year**" while "The median footprint of **wind** ... is **130 ha/TWh/year; if spacing is included, it is 12,000**." Thus, using only direct footprint, wind’s median land use is about 18 times that of nuclear (130 ÷ 7.1), and if turbine spacing is counted as occupied, wind’s median land use is about 1,690 times that of nuclear (12,000 ÷ 7.1).

The analysis notes: "First, we see that there are massive differences between sources. At the bottom of the chart we find nuclear energy. It is the most land-efficient source: per unit of electricity it needs 50-times less land compared to coal; and 18 to 27-times less than on-ground solar PV." It adds that for wind "the land use of wind farms is highly variable" and that the estimates include the entire project area, not just the turbine footprints. The article emphasizes there is a wide range in land-use intensity depending on layout and whether co-uses (like agriculture under turbines) are counted.

A National Renewable Energy Laboratory report for the National Academies finds that the *total* land area associated with U.S. wind facilities is about 30–141 hectares per terawatt‑hour per year, but the *direct* surface area occupied by turbines and access roads is just 0.3–1.3 hectares per terawatt‑hour per year. The authors highlight that much of the land within a wind project boundary remains available for other uses, unlike the fenced, continuously used area at a power plant.

This peer‑reviewed study by Hernandez et al. analyzes land‑use intensity (LUI) for multiple technologies in ha/TWh/year. It finds that "The median LUI was **7.1 ha/TWh/y for nuclear**, **130 ha/TWh/y for wind** (footprint only), **2,000 ha/TWh/y for ground‑mounted solar PV**, 58,000 for dedicated biomass, and intermediate values for fossil fuels." It adds that when the full spaced‑out area is counted, "**wind (spacing) was 12,000 ha/TWh/y**" and natural gas (spacing) 1,900 ha/TWh/y. Thus wind’s footprint LUI is around 18 times nuclear’s, while counting spacing makes wind’s LUI roughly three orders of magnitude higher than nuclear’s.

The World Nuclear Association states that nuclear power plants have “a relatively small land footprint” compared with many renewables. It cites analyses indicating that the land requirement of nuclear energy is typically measured in a few square kilometres per gigawatt of capacity, in contrast to wind farms which may spread over hundreds of square kilometres to achieve comparable annual electricity generation.

In its annex on technology parameters, the IPCC summarizes land-use data from multiple lifecycle studies. It presents ranges of **land use (m²-year per MWh)** for different power sources, showing that nuclear has among the lowest land requirements per unit of electricity, while onshore wind requires more land per MWh, especially if turbine spacing is included. The annex notes that land occupation for intermittent renewables is sensitive to capacity factor and layout, whereas compact thermal plants like nuclear concentrate generation on a smaller site.

Using calculations based on capacity factors, the post states: "A 1,000-MW wind farm would require approximately 85,240 acres of land (approximately 133 square miles)." It adds: "The land needed for wind energy to produce the same amount of electricity in a year as a 1,000-MW nuclear plant is between 260 square miles and 360 square miles." From this it concludes: "That means solar requires 34 to 57 times more land than nuclear. Wind requires 200 to 276 times more land than nuclear."

This explainer, produced by the MIT Climate Change Engagement Program, compares typical project scales: "Today, nuclear reactors range in capacity from about 300 megawatts ... to about 1600 megawatts. The average nuclear reactor has about 900 megawatts of capacity." It contrasts this to wind: "By comparison, the average capacity of a land-based wind turbine installed in 2022 was about 3 megawatts." It notes that even ignoring capacity factor, "hundreds of wind turbines would be needed to produce the same amount of electricity as the average nuclear project," though it does not attach a specific land-area multiple like 170× or 360×.

The guidance reviews published estimates of land requirements for various technologies, including nuclear and wind. A referenced table reports that typical **nuclear power plants** require on the order of **1–10 km² per GW of capacity**, whereas **onshore wind farms** may require hundreds of km² per GW when the entire turbine spacing is counted, but only a few km² are directly occupied by pads and roads. The document stresses the difference between "land take" (surface physically transformed) and "land use within a project area" that can remain available for agriculture or other functions, which is typical for wind projects.

In a meta-analysis of power generation projects, the authors report median total land-use intensities (including direct and indirect land) of roughly 12 m²·year per MWh for nuclear and around 72 m²·year per MWh for wind. This corresponds to wind using on the order of 6 times more land area per unit of electricity than nuclear when measured on a consistent lifecycle land-use basis, far below ratios in the hundreds.

The article notes that a simple snapshot comparison "shows that a solar or wind farm uses hundreds of times more land than the relatively tiny footprint of a coal or nuclear plant." In a table of land use it states: "When measured as a snapshot in time, land used for mining coal (0.09 acres per GWh) and uranium (0.06 acres per GWh) uses less land than solar (3 acres per GWh) and wind (26 acres per GWh)." The author emphasizes that this kind of comparison "has merit but it overlooks" that mining land is depleted while renewables continue producing from the same land over time.

Although focused on environmental impacts rather than a nuclear comparison, this LCA of a **wind power plant** and a **photovoltaic power plant** explains that land occupation over the life cycle is one of the ReCiPe impact categories, alongside climate change, particulate formation, and others. It notes that wind has a distinctive spatial footprint because of tower spacing but that only a fraction of the project area is permanently transformed; most of the land between turbines can remain under previous use, particularly agriculture.

GreenMatch explains that “to produce 1 gigawatt of power, it would require approximately 3.125 million photovoltaic (PV) panels,” assuming a representative panel capacity of about 320 watts. The same article notes that an equivalent‑scale solar farm or wind farm (about 333 utility‑scale turbines) would need much larger land areas than a 1‑gigawatt nuclear plant of similar annual output.

The author constructs an example comparing an APR1400 nuclear reactor to onshore wind. They state: "A typical nuclear plant site might cover about 1,000 acres (4 km²), much of which serves as a buffer zone." For wind, they assume 35% capacity factor and calculate that to average 1.4 GW would require "roughly 1,000-1,500 modern wind turbines" and that "A wind farm of this scale would require approximately 150,000 to 300,000 acres (600-1,200 km²) of land." This implies a land-use multiple on the order of 150–300× more land for wind than for the nuclear plant in their scenario, although they note much of the wind-farm land can still be used for agriculture.

In public debates, a specific claim that "wind farms require 360 times more land than nuclear" often appears in reports and op-eds referencing rough comparisons of total wind-farm lease area per unit of annual output versus the fenced footprint of a nuclear station. These figures are not traceable to a single standardized peer‑reviewed source and typically depend on optimistic nuclear land-use numbers, pessimistic wind land-use numbers, and counting all land within a wind project boundary as exclusively occupied, which overstates the effective difference.
