In the three regions, a large part of the total built-up area (urban and solar land) will consist of solar PV panels or CSP heliostats by 2050 if at least half of the produced electricity comes from solar power. So . Nat. Geographical distribution of the share of total land occupied by solar energy within each region, by agro-ecological zone. The National Renewable Energy Laboratory is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, operated by the Alliance for Sustainable Energy LLC. The countrys largest wind farm, Alta Wind Energy Center in California, has an installed capacity of 1,548 MW. Your land is a precious commodity to solar developers. The obtained land cover change imply environmental consequences such as greenhouse gas emissions and biodiversity loss47. Figure in an additional 8-10 acres more to house other solar system hardware plus the space needed between rows to avoid shading (and consequent power loss) as well as space for periodic array maintenance. YSG's market focus is distributed generation and utility-scale projects located within North America. The mean system size was calculated from the average and the high/low data, as was the +/- 1 standard deviation range. Solar, in utility-scale terms, is still relatively young in the grand scheme of things and so future reports will have a greater wealth of information to draw upon. ADS To the back of the envelope! Energy Policy 38, 69006909 (2010). Youre used to seeing amber waves of grain billowing in the breeze across acres and acres of farmland as far as the eye can see. by allowing extensive animal grazing), converting solarland to a net source of carbon sequestration35. 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. The NREL report suggests the acreage required for industrial-scale solar power plants is within the range of previous estimates, and generally doesn't seem off-the-charts outrageous. CPV is an advanced solar technology. IAMs which link energy, economy, land and climate modules tend to rely strongly on the cultivation of dedicated bioenergy crops (such as switchgrass and miscanthus) in global climate change mitigation scenarios43. The background scenario for the model exercises in this study consist of the Middle of the Road Shared Socioeconomic Pathway (SSP 2)52 with global CO2 reduction targets as defined by the Nationally Determined Contributions (NDCs) with increased ambitions after 203053. Overmars, K. P., Stehfest, E., Ros, J. P. M. & Prins, A. G. Indirect land use change emissions related to EU biofuel consumption: an analysis based on historical data. To give you a better idea of the type of solar power station that could operate on your land, consider a community solar farm. For specific regions, these penetration levels can even range up to 90%37. The authors declare no competing interests. CAS The EU, Japan and South-Korea have limited amounts of deserts and scrublands (see Table S4 in the SM), and of which a significant share is protected69. For simplicity, we have based the PF estimation on fixed tracking PV systems on flat land. If your state or county recently announced its goal for increasing renewable energy in a Renewable Portfolio Standard (RPS) within a certain time frame, solar developers will be working fast to achieve that mandate. But each case is unique. 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. & Fargione, J. See Methods section for a detailed explanation of each land management regime. Princeton University's Net-Zero America Project maps out potential energy pathways to a carbon-free U.S. economy by 2050. Solar developers scout out flat, clear land as ideally suited for a solar farm. For each land use, assumptions on carbon stocks in the vegetation and the soil are made (see Table S1 in SM). Nat. Market supply and demand for solar farms, Top 7 tips for farmers about solar farm leases, Key takeaways on solar farm land requirements, Ultimate Guide to Solar Panel Size and Weight for Homes and Businesses. However, in semi-arid pastures with wet winters, opposite effects are observed, and microclimates below panels seem to enhance vegetation growth64. 05, 1450003 (2014). When it comes to solar farms, everything is calculated in a similar fashion but on a much grander scale. Solar farms can take up a few acres of land or tens of thousands. We use ArcGIS to draw polygons around satellite imagery of each plant within our sample, and to calculate the area occupied by each polygon. Figure2 shows the obtained land cover changes related to increasing solar energy (see Table 1), within each of the three regions (upper part of the figure), and indirectly driven land cover changes outside of these regions in the rest of the world (lower part). To determine the cost of a solar-plus-storage system for this study, the researchers used a 100 megawatt (MW) PV system combined with a 60 MW lithium-ion battery that had 4 hours of storage (240 megawatt-hours). 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. 11, 6175 (1987). Calvin, K. et al. PRE_2017_2_0139). Energies 12, 2533 (2019). When using relatively efficient PV technologies such as monocrystalline and multicrystalline silicon (made from a single crystal of silicon and from many silicon fragments melted together, respectively) (lower range of estimated LUC emissions, higher range of non-land life cycle emissions), our results show that LUC emissions are comparable to about 10 to 50% the current non-land life cycle emissions for such technologies. Energy Rev. YSG Solar is a project development vehicle responsible for commoditizing energy infrastructure projects. vary. 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. Policy 17, S148S169 (2017). 3 and Table 2) from 2020 to 2050 have been calculated using Eq. Science (80-. ) Wise, M. et al. prepared the topic and framing of the paper. By submitting a comment you agree to abide by our Terms and Community Guidelines. Direct-area requirements: Generation-weighted average is 2.9 acres/GWh/yr. Or maybe not. Figure2 shows that, either directly or indirectly, expansion in solar energy predominantly reduces non-commercial land cover on a global scale: for every 100 hectares of solarland in the EU, we find that, depending on the solar penetration level, 31 to 43 hectares of unmanaged forest may be cleared throughout all the world. D.V. By comparing the totalLUC emissions from one unit ofsolar and bioenergy to the avoided periodicalcombustion emissions from natural gas fired electricity, we calculate the CO2 payback period of these renewable alternatives for electricity production, which is a common method to compare LUC emission impacts of different types of bioenergy13,44. GCB Bioenergy 4, 372391 (2012). The size of a solar farm defines how much electricity it creates. If you are seeking utility-scale technology cost and performance estimates, please Prospects of life cycle assessment of renewable energy from solar photovoltaic technologies: a review. & Rovers, C. P.P. Consistently exporting or importing large shares of solar energy between geographically and/or politically distinct regions faces both technical and geopolitical challenges. Dupont, E., Koppelaar, R. & Jeanmart, H. Global available solar energy under physical and energy return on investment constraints. Granted your property adheres to all necessary solar farm land requirements, the typical solar farm lease rate varies between $600 $1,200 per acre for every year of your contract. Green Coast is supported by its readers. How To Set Up A Solar Power Plant In India The Right Way Natl. Timilsina, G. R., Kurdgelashvili, L. & Narbel, P. A. Sci Rep 11, 2907 (2021). Note that these results do only focus at solar and bioenergy based in land with potential commercial use. Land Use & Solar Development | SEIA Quantifying a realistic, worldwide wind and solar electricity supply. See Section 2 of the Supplementary Material (SM) for an overview of the scenarios designed for this study. At the domestic level, solar energy is found to predominantly compete for land with cropland and managed forests, while on a global scale, 27 to 54% of the land required for solar energy is found to indirectly displace unmanaged forests, predominantly outside the region where the solar energy is consumed. ft. of roof space to house a 7.5kW residential solar system. 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. Change 123, 495509 (2014). ADS Rep. 9, 11442 (2019). Science (80-. ) Renew. & Sorman, A. H. Energy transitions and the global land rush: ultimate drivers and persistent consequences. 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. Energy 257, 113968 (2020). Areas directly below solar modules are cleared for the construction phase, but weeds might grow after that phase. Anal. & Markandya, A. 642260, 821105), Ministerio de Ciencia, Innovacin y Universidades (Grant No. Thank you for visiting nature.com. Google Scholar. natural gas).

CAS volume11, Articlenumber:2907 (2021) Sometimes, the RPS will accompany tax incentives for solar projects, making solar farm projects even more attractive to both developers and farmers. Also called solar parks, plants, fields, or power stations, solar farms are becoming commonplace throughout the world. We concentrate on three regions with heterogeneous features where futures with a high solar energy penetration have been identified in the literature as likely to induce land competition: the European Union (EU), India and jointly Japan and South-Korea. They have much to gain from you and want you to sign on with them. Global land-cover changes by 2050 due to solar expansion, for a range of solar energy penetration levels and for an average efficiency of installed solar modules of 24% by 2050. Tata Power Solar has demonstrated that it is possible to build a 10 MW solar power plant in just 4 months. Policy 14, 248257 (2011). President Tsai Ing-wen Inaugurates Vena Energy's 272 MW E2 Solar 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). Renew. All vegetation in previous land cover above 30cm height, such as trees, bushes and high grass, will be removed such that the vegetation that is left is similar to that in pastures. Further work applying ecological tools should be focused towards investigating the implications of these additional land occupation levels -including the additional transmission power lines- in terms of habitat fragmentation and ecosystem disturbance.
