Uncertainty bounds reflect solar module efficiency scenarios (reaching average efficiencies of 20, 24 and 28% for modules installed in 2050; see Section2c in SM). database with data from actual systems in the field, and interviewing NREL experts. YSG Solar is a project development vehicle responsible for commoditizing energy infrastructure projects. Therefore, we implicitly assumed that those hectares that are converted to solarland in our scenarios are indeed suitable for hosting solar energy. For comparison, the District of Columbia's total land area is 68 square miles. For example, the literature estimates that the indirect land competition induced by liquid biofuels in developed regions leads to global land clearing and associated iLUC emissions higher than the emission savings achieved by replacing gasoline by these biofuels during 30 years11,12,13.

Impacts of photovoltaic farms on the environment in the Romanian Plain. & Rovers, C. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. At higher solar penetration rates however, increasing land pressure causes more natural forests to be used for timber or crop production, leading to higher land use change emissions outside the region.

This is the standard area used in calculations of this sort. The land cover changes inFig. When buying in large quantities for solar farm projects, solar developers save on equipment costs. 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. Dolman, A. J., Verhagen, A. 1 Non-land life cycle emissions of PV are based on a range of PV technologies, including mono and multicrystalline silicon (higher range), thin-film CdTe (lower range), CIS and a-Si systems as calculated in Liu & van den Bergh (2020)42, and based on an average global carbon intensity of electricity (0.48kg CO2/kWh). Finally, a public utility may announce an upgrade to or new construction of its infrastructure in a certain area. Further background assumptions related to the modelling can be found in the SM. Nonhebel, S. Land-use changes induced by increased use of renewable energy sources. (5), depends on the packing factor (PF) and the Generator-to-system area (GSR).

Turney, D. & Fthenakis, V. Environmental impacts from the installation and operation of large-scale solar power plants. 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. The results highlight the exemplary performance reliability of nuclear energy facilities as well as the very high energy density of nuclear fuel. 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. This means less than 5 of slope, but more may be acceptable if its facing south. Wind and solar provide 98% of electric power by 2050. For example, the sprawl of bioenergy has been already identified as the major driver of recent land use change (LUC) in developed regions5,6. This occupation is unequally spread within each of the regions, as areas that are relatively attractive for solar energy are prioritized in each region, such as southern Europe, north western India, and southern Japan and South-Korea (see Fig. 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. That's if we spread solar panels evenly across the entire country. De Marco, A. et al. Table 1. Use the tabs below to navigate the charts. As countries, states, and municipalities transition toward phasing out fossil fuels as energy sources, they are actively looking to expand clean energy capacity namely, solar and wind energy in their jurisdictions. Figure3 and Table 2 show the obtained LUC emissions per unit of solar energy installed from 2020 to 2050 associated to the different simulated solar penetration and module efficiency scenarios, and for different management regimes of the land in solar parks. Land that is not used and neither has potential for any other productive use from a human perspective, such as deserts and dry scrublands, can be suitable for solar energy. Report Counts Up Solar Power Land Use Needs - IEEE Spectrum However, the energy density of solar energy is a magnitude higher than that of bioenergy. This means that a solar power plant that provides all of the electricity for 1,000 homes would require 32 acres of land. Energy Rev. Nuclear power is often considered very area efficient, though mining for uranium could add a complicated factor to that equation. Energy 36, 27252732 (2011). Default system size values from NREL tools such as Renewable Energy Optimization (REopt) and In My Back Yard (IMBY) were also used. Change 123, 691704 (2014). To date, land use for solar energy is negligible compared to other human land uses. Land Use Glob. The impacts of each of these solarland management regimes on the local carbon cycle depend on the specific location, and the previous land use, and result from off-model calculations applied to the GCAM scenario outcomes which provide land cover changes per year, AEZ, and scenario. (2), and the CO2 payback period (Table 2) has been calculated using Eq. Equation(4) defines this yield for each AEZ, which depends on average solar irradiation (I) per AEZ, average efficiency of solar power plants (f1) at the year of installation (t), the averaged performance ratio over the life cycle of the solar power plant (f2) and the land occupation ratio (f3)1,17. See Section3b in the SM for aggregated global land cover changes. Ministry of Housing Communities and Local Government. Energy Policy 39, 11541169 (2011).

This size solar farm can power a large energy user or provide power back to the local utility company. is a project development vehicle responsible for commoditizing energy infrastructure projects. for timber products or biomass). Nat. A 10 MW solar power plant requires between 5 and 10 acres of land. They show that solar expansion scenarios until 2050 will most likely lead to net LUC emissions, although there can be a net carbon sequestration in India when managing the land in solar parks as pastures. https://www.nrel.gov/docs/fy12osti/51946.pdf (2012). Uncertainties in terms of future solar module efficiency improvements up to 2050 (20, 24, 28%)are taken into account, as well as solar land management options and their different associated impacts on local carbon cycles: depending on how the land below and around solar energy installations is managed, and on the land use prior to the conversion to solarland, land transformation for hosting USSE can cause a net release of carbon that was stored in soil and vegetation, or can lead to net carbon uptake38. When it comes to renewables, there's no doubt that solar power is far more area-efficient than wind power; an NREL report[PDF] from several years ago found a total requirement of about 84 acres per MW, a far cry from the 10 or so acres that solar seems to max out at. Japan to slash solar subsidies as feed-in tariff costs mount (2019). How Big Is A 100 Mw Solar Farm? [Updated: April 2023] 1). 2), and estimated LUC emissions per kWh are below 12g of CO2 for all scenarios. 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. For example, higher placed modules are beneficial for vegetation growth below the modules, as it allows more sunlight to reach the vegetation. The proposed solar PV power plant is capable of producing 180GWh per year of electricity and reducing 90,225 tons/year of CO 2 emissions. Change 9, 323329 (2019). A utility project may be sized at 25 MW up to 1 GW (1 gigawatt = 1,000 megawatts). Modules are placed at ground level, which is cheaper, and the absence of vegetation avoids shading effects. Also, the optimal microclimate for solar energy production (based on insolation, air temperature, wind speed and humidity) is found over land that is currently used as cropland61, supporting the assumption that future investors will have a slight preference for cropland (in use or fallow) for the allocation of solar energy projects, among other factors such as flatness and connectivity in terms of roads and electricity grids22. Material bottlenecks in the future development of green technologies. North American Renewable Integration Study, Solar for Industrial Process Heat Analysis, Office of Energy Efficiency and Renewable Energy, Solar Water Heat, flat plate & evacuated tube. https://doi.org/10.1007/978-94-017-0335-2_8.

The future land requirements of solar energy obtained for each scenario and region can be put in perspective compared, for example, to the current level of built-up area and agricultural cropland. Science (80-. ) to be used for a high level estimation of initial system capacity. As long as you meet the minimum solar farm land requirements, solar leasing is an easy and consistent way to generate income. Environ. 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. If your lawyers negotiating skills are outstanding or the solar developer is desperate for your land adding in partial royalty payments would increase your income even more. The E2 Solar Project is built on reclaimed land spanning 226 hectaresapproximately the size of more than 316 football fieldsand features 680,000 solar photovoltaic panels with an installed capacity of 272 MW, capable of generating around 400-million kWh annually, equivalent to the annual electricity requirements of more than 90,000 Taiwanese households. and In My Back Yard (IMBY) were also used. Using it, youll be able to predict the largest solar farm size that your property could reasonably service. Ludin, N. A. et al. Nat. 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. Similarly, coal power plants themselves don't use a ton of space per megawatt generated, but there is little debate on the devastating land use impacts of coal mining. Denholm, P. & Margolis, R. M. Land-use requirements and the per-capita solar footprint for photovoltaic generation in the United States. However, recent studies based on satellite views of utility-scale solar energy (USSE) under operation, either in the form of photovoltaics (PV) or concentrated solar power (CSP), show that their land use efficiency (LUE) is up to six times lower than initial estimates17,18,19. Of all the major factors that influence solar farm lease rates, this one is most likely to evolve over time. 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. To capture the whole picture we compare these footprints based on life-cycle assessments. Renew.

In the past, they estimated that to power all of the U.S. with solar power, it would require 0.6 percent of all the area in the country. A 2015 report,Land Requirements for Carbon-Free Technologies, comparedthe land area that various types of electricity generation facilities would require to produce the same amount of electricity as a 1,000-megawatt nuclear power plant in a year. According to a report from the National Renewable Energy Laboratory, roughly 22,000 square miles of solar panel-filled land (about the size of Lake Michigan) would be required to power the entire country, including all 141 million households and businesses, based on 13-14% efficiency for solar modules. CSP towers & CPV installations: About 3 acres/GWh/yr. This quantity is called their capacity to generate electricity. Green Coast is supported by its readers. Grid extension might cost up to Rs. Energy Policy 37, 9921003 (2009). Not bad! Energy Rev. An additional module has been developed for the GCAM model to link the consumption of solar energy with land use, competing with other commercial (crops, timber and intensive pastures) and non-commercial (natural forest, grassland, scrubland) land uses. Additionally, policy and regulation surrounding land-use for solar is also developing and changing frequently. YSG's market focus is distributed generation and utility-scale projects located within North America. A large plot of land (hundreds of acres) is often more valuable on a per acre basis than a smaller one if a solar developer is looking to build a huge solar power station. Based on the national average of four peak sun hours per day, we know that the average 1 MW solar farm would make 1,460 MWh per year. Solar energy: markets, economics and policies. Instead, solar energy penetration is not found to significantly affect the cover of unmanaged land in each of the three regions.

GSR ranges of 0.70.85 have been reported63 although larger plants tend to have lower GSR due to more difficult use-optimization of land plots at large scale productions, hence here we take a GSR of 0.7 assuming that the deployment of scale of solar power plants on land will likely be based on larger-size plants due to the incentives of economics of scale17,19. Sustain. Direct-area requirements: Generation-weighted average is 2.9 acres/GWh/yr. Therefore, apart from the 10% of scrublands which enter by default into the land competition module, we assumed no additional availability of suitable deserts and scrublands for solar energy in these regions. Alternatively, the developers will sell the electricity to large corporations, institutions, or university systems that have massive demands for power in centralized settings. Small 2-axis flat panel PV power plants: 5.5 acres/GWh/yr.

The potential land requirements and related land use change - Nature All authors reviewed the manuscript. Nat. With solar energy accounting for 25 to 80% of the electricity mix, land occupation by USSE is projected to be significant, ranging from 0.5 to 2.8% of total territory in the EU, 0.3 to 1.4% in India, and 1.2 to 5.2% in Japan and South-Korea. Send us an email, or call at 212.389.9215 to get started. Clim. Still, we do find a non-negligible effect in this study. Pasture conversion: Irrespective of the previous land use, all land below and around the infrastructure is (re)seeded with grass before or right after the construction phase, and the land will be managed as pasture, allowing for extensive animal grazing around the solar modules35. On top of that, spatial frictions might occur if land which is made available for solar energy by national or local governments is in reality a biodiversity hotspot29,30 or the home of human communities31,32. 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. Although a general good correspondence is found, there are also exceptions (see Figure S6 in the SM). In fact, instead of using a land measurement to describe the size of a solar farm, they are classified according to how much electricity they can generate from the sun. 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. Others interested in solar energy may enter into power purchase agreements (PPAs) with public utilities at a fixed cost for a certain length of time. Solar energy in urban areas, deserts and dry scrublands, as well as bioenergy from waste or agricultural and forestry residue, are assumed not to contribute to LUC emissions nor carbon sequestration. A 5 MW solar farm requires approximately 30 to 40 acres of land. There shouldnt be trees or buildings that can obstruct sunlight or cause shading issues. Ministry of New and Renewable Energy (MNRE) and state nodal agencies are also providing 20%-70% subsidy on solar for residential, institutional, and non-profit organizations to promote such green energy sources.
