If the solar company goes out of business before your lease is up, you could be stuck with costly PV module and cement ballast disposal before you can begin farming again. Gonzlez-Eguino, M., Capelln-Prez, I., Arto, I., Ansuategi, A. Land use and agricultural output in GCAM version 4.3 are calibrated for pre-defined Agro-Ecological Zones (AEZs), which sub-divide geo-political regions in 18 different types of land regions, based on differences in climate zones (tropical, temperate, boreal) and the length of growing periods for crops54. 100% clean and renewable wind, water, and sunlight all-sector energy roadmaps for 139 countries of the world. Wind farms require up to 360 times as much land area to produce the same amount of electricity as a nuclear energy facility, a Nuclear Energy Institute analysis has found. However, the obtained results show that in future scenarios, with a largely decarbonized electricity system, high penetration rates of solar energy will require significant amounts of land to be occupied by solar power plants. Energy Rev. Sustain. Sci. Capelln-Prez, I., de Castro, C. & Arto, I. Assessing vulnerabilities and limits in the transition to renewable energies: land requirements under 100% solar energy scenarios. Rao, G. L. & Sastri, V. M. K. Land use and solar energy. Hernandez, R. R. et al. SunPower Solar Panels Review 2023: What is the Best Panel to Buy? Energy Rev. Renew. Sustain. In order to identify the effects that solar energy and bioenergy pathways have on land use and land use change emissions, three pathways have been modelled achieving a defined penetration level in the electricity mix from 2020 to 2050, using different electricity generation technologies (see Section2b in the SM on how the different penetration levels have been modelled): Solar energy pathway (S): land-based PV, rooftop-based PV, CSP. During the exploratory phase of a solar farm project, extensive testing on your land could result in significant crop damage that youre left to repair or remove. Google Scholar. This structure is based on observed tendencies for solar siting in Europe, India, Japan and South-Korea (see Table S2 in SM), showing that mainly arable land is used for current USSE projects, and supported by academic literature17,33,34,57,58 and solar industry reports59,60. Solar farms in areas that get plenty of sun year-round, such as the southwestern United States, will generate more energy per acre than solar farms in the northern states. . Nonhebel, S. Land-use changes induced by increased use of renewable energy sources. 6 Best Solar Fence Chargers in 2023: Who Makes the Best Product? The project consists of 220,750 modules. Solar yields can slightly differ (about 25% in both ways) for 1- or 2-axis PV tracking systems or for CSP systems19. Total-area capacity-weighted average: 8.9 acres/MWac. Sometimes, the RPS will accompany tax incentives for solar projects, making solar farm projects even more attractive to both developers and farmers. The induced global land cover changes and related LUC emissions are then compared with scenarios where the same emission reduction targets in the electricity sector are achieved without solar and bioenergy, to isolate the additional land requirements, land cover impacts and related LUC emissions provoked by solar and bioenergy. (5), depends on the packing factor (PF) and the Generator-to-system area (GSR). Adeh, E. H., Good, S. P., Calaf, M. & Higgins, C. W. Solar PV power potential is greatest over croplands. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in As the land use impacts of bioenergy have been extensively analysed in other studies, using the same model9,39, we proceed to compare the land occupation and related LUC emissions of electricity production from solar energy and bioenergy, with the purpose of improving the comparability of the obtained results. Thank you for visiting nature.com. Technoecological synergies of solar energy for global sustainability. By comparison, a residential rooftop or ground-mounted solar system costs between $2.50 and $3.50 per watt. For larger PV plants, the total area needed is 7.9 acres per MW, while concentrating solar power plants (CSP) need 10 acres per MW. Change 22, 588595 (2012). Single- and dual-axis trackers move the PV modules up and down and from left to right during the day in order to capture the maximum amount of sunlight all the time. Using an existing IAM to study the potential land impacts of solar energy expansion, we were bound to the limitations of this model. For comparison, a traditional 1 MW coal power plant requires about 40 acres of land. 319, 12351238 (2008). The island of Manhattan is 34 square miles, and New York Citys five boroughs (Manhattan, Brooklyn, Queens, Staten Island and the Bronx) take up 305 square miles. This limitation could be dampened in future work by using/developing a land cover layer that matches better with geographical differences in solar irradiation and latitude. The key variable in that 4-7 acre range is how sunny it is in your area. PF is the ratio between the PV panels or heliostats and the ground area required for arrays installation including separation to avoid excessive self-shading, while GSR represents the share of the full area enclosed by the site boundary of the power plant which is covered by the PV panels and heliostats including the separation between them. https://digitalscholarship.unlv.edu/renew_pubs/25 (2008). Policy 17, S148S169 (2017). Calvin, K. et al. https://energia.gob.es/es-es/Participacion/Paginas/DetalleParticipacionPublica.aspx?k=236 (2020). Comparing the additional global LUC emissions until 2100 as a result of reaching certain shares of bioenergy in the electricity mix of 2050 in the regions in this study, we observe from Table 2 that emissions per dedicated m2 are in many cases lower than for solar energy at the same penetration level in the electricity mix.

Prospects of life cycle assessment of renewable energy from solar photovoltaic technologies: a review. Search out solar industry professionals for their input, too, before making a final decision. Liu, F. & van den Bergh, J. C. J. M. Differences in CO2 emissions of solar PV production among technologies and regions: application to China, EU and USA. GCAM v4.3 Documentation. The land cover changes inFig. The uppergraphs shows total land cover changes by 2050 relative to 2015 within each region and the lower side shows the land cover changes in the rest of the world (leaking), indirectly driven by the penetration of solarland within the region. Recent developments show that USSE in densely populated countries is often installed on arable land that is used or potentially suitable for other productive uses such as agriculture or forestry17,26,33,34, intensifying land competition for the same reasons as the sprawl of bioenergy does. Have you considered leasing your land as a solar farm? . Use the tabs below to navigate the charts. The table below, courtesy of the National Renewable Energy Laboratory, highlights the differences in land-use requirements for PV and CSP projects across the United States. provided geographically explicit inputs to the analysis and all map-based figures. de Vries, B. J. M., van Vuuren, D. P. & Hoogwijk, M. M. Renewable energy sources: their global potential for the first-half of the 21st century at a global level: an integrated approach. ft., that works out to be about 11 acres needed for a 5 MW solar park. For simplicity, we have based the PF estimation on fixed tracking PV systems on flat land. Nat. 40% of power plants: Within 6 and 8 acres/MWac. Energy sprawl is the largest driver of land use change in United States. D.V. In contrast, if arable land plots are converted to solar parks whose surface is managed as pastures, there will be a net carbon sequestration in vegetation and soil in the decades following upon the conversion (apart from the land directly below the panels, where photosynthesis is largely blocked)35, offsetting some or all of the inevitable LUC emissions caused by land competition. ADS The range is calculated by dividing the regionally weighted solarelectricity output per m2 as used in this study, by CO2 emissions per m2 panel surface. Renew. See Table S5 in the SM for the assumed values of the parameters in Eq. Energy Policy 37, 9921003 (2009). As a consequence, the transition to these sources of energy is expected to intensify the global competition for land2,3,4. Google Scholar. Change 5, 604 (2015). Interplay between the potential of photovoltaic systems and agricultural land use. CAS , in utility-scale terms, is still relatively young in the grand scheme of things and so future reports will have, The image below, also courtesy of the NREL report, shows both direct and.

A.) Denholm stressed that doing such studies that use actual, existing plants for coal, nuclear, and natural gas would allow us to more firmly compare which energy sources get us the most bang per acre. Hahn, E. The Japanese Solar PV Market and Industry. Grid extension might cost up to Rs. Energy 36, 27252732 (2011). To date, land use for solar energy is negligible compared to other human land uses. YSG's market focus is distributed generation and utility-scale projects located within North America. Ministry of Housing Communities and Local Government. Sustain. Due to the lower irradiance and higher latitude of Europe, absolute land use of per unit of solar output is almost twice as high as in Japan and South-Korea and three times higher as in India (see Fig S6 in the SM). World-class safety being the company's strength, we delivered the plant with a robust safety management system and 1.3 million safe man hours put in. Armstrong, A., Ostle, N. J. Well include a full table further down, but these are some of the, All solar technologies: Total area generation-weighted average is, Direct-area requirements: Generation-weighted average is, Direct land-use requirements: Capacity-weighted average is, The table below, courtesy of the National Renewable Energy Laboratory, highlights the differences in land-use requirements for, The NREL notes that some solar categories have small sample sizes and that high-quality data isnt necessarily available for. For specific regions, these penetration levels can even range up to 90%37. Using it, youll be able to predict the largest solar farm size that your property could reasonably service. See Methods section for more details. Solar photovoltaic (PV) facilities require up to 75 times the land area. Denholm, P. & Margolis, R. Supply curves for rooftop solar pv-generated electricity for the United States. Farmers, ranchers, and landowners in search of a predictable way to receive passive income should determine if they meet the solar farm land requirements for leasing a solar project on their property. There are two main types of solar projects that solar developers are actively pursuing right now all over the United States: In the case of solar farms consisting of thousands or hundreds of thousands of PV modules on your property, the developers will sell the electricity created by the solar panels to a public utility in urban and suburban areas. In India, where current and projected crop productivities are below the global average, the impact of solar expansion on global land competition is less significant. The resulting land cover changes, including indirect effects, will likely cause a net release of carbon ranging from 0 to 50 gCO2/kWh, depending on the region, scale of expansion, solar technology efficiency and land management practices in solar parks. Renew. They will come looking for you! Princeton University's Net-Zero America Project maps out potential energy pathways to a carbon-free U.S. economy by 2050. The installation of USSE on land is subject to a diversity of constraints: solar resource constraints, which are related to the solar irradiance in a certain area; geographical constraints such as the slope and the existing use of the land; and regulatory constraints, e.g. For sources of renewable energy other than bioenergy, land requirements and the associated environmental impacts remain understudied in the literature from a quantitative point of view1,10. for timber products or biomass). (2), and the CO2 payback period (Table 2) has been calculated using Eq. Miller, L. M. & Keith, D. W. Climatic impacts of wind power. Sci Rep 11, 2907 (2021). We may earn an affiliate commission at no extra cost to you if you buy through a link on this page. Dolman, A. J., Verhagen, A. Clim. GCB Bioenergy 4, 372391 (2012). Table 2 also shows the obtained emissions per m2 of land occupation by solar energy, which reflect the value of the used land in terms of its potential to sequester carbon: either directly by its capacity to sequester carbon in soil and vegetation, or indirectly by its agricultural productivity which, if being displaced by solarland, will lead to conversion of non-commercial land to agricultural land elsewhere. The U.S. energy footprint quadruples in size. Jacobson, M. Z. See Section3b in the SM for aggregated global land cover changes. Google Scholar. A solar PV facility must have an installed capacity of 3,300 MW and 5,400 MW to match a 1,000-MW nuclear facilitys output, requiring between 45 and 75 square miles. In reality, the application of a particular land management practice depends on a diversity of local factors (policies, climate, etc.). See below for more on what makes your land ideally suited for a solar farm. Put your land to work for you and the planet. Energy Policy 38, 69006909 (2010). Evidence from agrivoltaic systems show that year-round leaf growth below solar infrastructure is about 20% lower below solar modules, and that this effect is strongest in summer65. Nuclear power is often considered very area efficient, though mining for uranium could add a complicated factor to that equation. Since in our simulations land for USSE predominantly replaces commercial land growing crops or timber products within each region(see Fig. from different solar developers before deciding on one. 25, 727745 (2017). Sharma, C., Sharma, A. K., Mullick, S. C. & Kandpal, T. C. Assessment of solar thermal power generation potential in India. volume11, Articlenumber:2907 (2021) Land-use change to bioenergy production in Europe: implications for the greenhouse gas balance and soil carbon. Nevertheless, an important driver for land use decisions in the model is land profitability: even if land covered by crop cultivation is perceived as the most suitable by investors in solar energy, high observed or potential profitability of crop cultivation on such land could force investors to focus on other land types. Book 2013 report Land-Use Requirements for Solar Power Plants in the United States . Our in-depth analysis on all the essentials about solar farm land requirements concludes with a list of the top 7 tips for farmers, ranchers, and landowners thinking about leasing their property to a solar developer or solar storage business. The capital inputs per unit of output depend only on IAEZ, f1t and f2 and since capital costs tend to be larger than land costs, investors in solar energy tend to choose the location predominantly based on solar irradiance instead of the solar energy yield per land unit. Among the findings: A large fixed tilt photovoltaic (PV) plant that generates 1 gigawatt-hour per year requires, on average, 2.8 acres for the solar panels.
