Nat. forest or pasture). For a quick return on investment, solar developers are usually unwilling to build a solar farm under 1 MW in capacity. 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. visit the Transparent Cost Database website for NREL's information regarding vehicles, biofuels, and electricity generation. Lovich, J. E. & Ennen, J. R. Wildlife conservation and solar energy development in the desert southwest, United States. 40% of power plants: Within 6 and 8 acres/MWac. 5 lakh per acre. Finally, a public utility may announce an upgrade to or new construction of its infrastructure in a certain area. Grid extension might cost up to Rs. The packing factor again depends on the average latitude of each AEZ and is defined by Eq. 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). Nat. Grid extension might cost up to Rs. The key variable in that 4-7 acre range is how sunny it is in your area. When weighted by generation rather than capacity, the larger PV plants (3.4 acres per gigawatt-hour per year) and CSP plants (3.5 acres/GWh/year) do a bit better than smaller PV plants (4.1 acres/GWh/year). One of these was the division of land zones in the model (corresponding to Agro-Ecological zones, see Methods section), which determine the boundaries of the geographical competition to host solar energy within each region. 319, 12351238 (2008). Land use and carbon mitigation in Europe: a survey of the potentials of different alternatives. This is where you, as a farmer, rancher, or general landowner, come into the picture. Change 123, 691704 (2014). More land is needed to mine the coal, and dig the metals and minerals used in solar panels out of the ground. For a quick return on investment, solar developers are usually unwilling to build a solar farm under 1 MW in capacity. Although a general good correspondence is found, there are also exceptions (see Figure S6 in the SM). 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. Types of . To start, think of something more familiar: a rooftop solar array. Taking these constraints into account, rooftop space is limited to 3% of expected urbanized land by 2050 (end year of the scenarios in this study) in each geo-political region, while non-optimality of rooftop space has been modelled through a supply curve which represents increasing capital costs for each additional space used for rooftop PV systems68. In Frontiers in Econometrics (Academic Press, 1974). See Section1a in the SM for more details, and see Wise et al.56 for a detailed explanation on the approach and design of the land module in GCAM. Fargione, J., Hill, J., Tilman, D., Polasky, S. & Hawthorne, P. Land clearing and the biofuel carbon debt. 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. To build the amount of wind and solar needed to support the grid, the U.S. energy footprint would quadruple in size, and wind farms would occupy areas equivalent to Arkansas, Iowa, Kansas, Missouri, Nebraska and . All solar technologies: Total area generation-weighted average is 3.5 acres/GWh/yr. Cite this article. A. et al. CPV is an advanced solar technology. When it comes to solar farms, everything is calculated in a similar fashion but on a much grander scale. It is based on a large, nearly complete sample of ground-mounted PV plants larger than 5 MW-AC that were built in the United States from 2007-2019. 350, 11681169 (2015).

A change in land cover either leads to positive or negative LUC emissions, driven by the difference in the assumed carbon stocks (in vegetation and soil) between the original and the new land use. Send us an email, or call at 212.389.9215 to get started. Due to the potential relevance and relatively low power density of solar energy in a decarbonized future, and given that PV in urban areas will only be able to cover a share of the total demand1,21, this paper aims to quantify the potential land occupation of solar energy installed up to 2050, and the related direct and indirect impacts on carbon cycles, within a context of global climate action as proposed in the Paris Agreement. Google Scholar. Land-use transition for bioenergy and climate stabilization: model comparison of drivers, impacts and interactions with other land use based mitigation options. 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. Renew. Energy Rev. Land Use Policy 81, 725735 (2019). Finally, we have not taken into account the potential to integrate solar systems in agricultural land (agrivoltaic systems), a technique that is currently in an early stage of research and development and of which the large-scale performance is still uncertain49. 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. A combination of technical and geopolitical reasons complicates the installation of solar energy far from consumption points. Comparing the non-land life cycle emissions from LCAs to the LUC emissions estimated in this study, we can conclude that LUC emissions (which are normally not included in LCAs) increase total life cycle emissions of new USSE projects by 10 to 150% in the absence of land management practices focused on sequestering carbon in solarland, depending mainly on the region where the infrastructure is installed and the type of technology used. A utility project may be sized at 25 MW up to 1 GW (1 gigawatt = 1,000 megawatts). A 10 MW solar power plant requires between 5 and 10 acres of land. Hence, a coordinated planning and regulation of new solar energy infrastructuresshould be enforced to avoid a significant increase in their life cycle emissions through terrestrial carbon losses. When weighted by generation rather than capacity, the larger PV plants (3.4 acres per gigawatt-hour per year) and CSP plants (3.5 acres/GWh/year) do a bit better than smaller PV plants (4.1 acres/GWh/year). Instead, solar energy penetration is not found to significantly affect the cover of unmanaged land in each of the three regions. Nor should there be waterways. ft. The report used land use data from 72 percent of all large solar plants installed in the U.S., and found that the total area requirements for a photovoltaic (PV) plant between 1 and 20 megawatt capacity is 8.3 acres per MW. 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. 9, 191201 (2005). for timber products or biomass). Geographical distribution of the share of total land occupied by solar energy within each region, by agro-ecological zone. , the land-use requirements for solar power plants are wide ranging across different technologies. That is why we have framed the uncertainty related to local carbon cycle impacts on management decisions, based on three different regimes identified through literature review: Land clearing: Clearing and grubbing of soil and roots, topsoil stripping and stockpiling, land grading and levelling, and soil compaction. Clim. Prospects of life cycle assessment of renewable energy from solar photovoltaic technologies: a review. Have you considered leasing your land as a solar farm? 96, 1128 (2018). 2), solar energy expansion displaces commercial timber production to other regions, indirectly increasing carbon sequestration outside the region by incentivising currently degraded forest or other arable land to be commercialised for timber production. simultaneously building 9, 100 MW in new wind capacity, 5,300 MW in new solar PV capacity, and 8,300 . Econ. Additionally, policy and regulation surrounding land-use for solar is also developing and changing frequently. Energy Rev. costs, O&M, performance, and fuel costs. D.V., I.C.P. Well include a full table further down, but these are some of the key numbers from the report. In Japan and South-Korea, LUC emissions related to the expansion of solar energy are 11 to 35g of CO2 per kWh. Table 1 shows that land requirements for reaching certain levels of electricity penetration with solar energy are about a magnitude lower than land requirements to meet those same levels with bioenergy. Google Scholar. The advantages gained from satisfying the minimum of 6-8 acres of solar-ready land per megawatt needed to construct the smallest of community solar farms may outweigh any disadvantages as detailed in this article. According to the MIT authors, powering 100 percent of estimated U.S. electricity demand in 2050 with solar energy would require roughly 33,000 square kilometers (sq-km) of land. 22% of power plants: Within 8 and 10 acres/MWac. Numerous Life Cycle Assessments (LCA) have been performed for solar energy, estimating the life cycle emissions of solar energy systems depending on many factors, such as the year and location of construction, solar module efficiency, mounting system, location of input production, among others42,48. 05, 1450003 (2014). Changes may happen on short notice, propelling solar developers to hunt out suitable land for solar farms and get signed contracts quickly. Gonzlez-Eguino, M., Capelln-Prez, I., Arto, I., Ansuategi, A. SolarEdge vs Enphase: Which Solar Brand Is Better? On the other side, rooftop spaces are often not optimal, and only about 2 to 3% of urbanized surface area can be used for PV systems with reasonable efficiencies (taking into account specific factors such as roof slopes and shadows between buildings)1,21. and I.A. Of course, given the rapid development of renewable energy and solar energy technologies in particular, this NREL report can only account for past performance and doesnt necessarily reflect the future trends of land-use requirements for solar power plants. On the role of solar photovoltaics in global energy transition scenarios. Note thats just for the panels. 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. Google Scholar. Solar yields can slightly differ (about 25% in both ways) for 1- or 2-axis PV tracking systems or for CSP systems19.

Stop right there. See full disclosure. For comparison, the District of Columbia's total land area is 68 square miles. Can Paris pledges avert severe climate change?. 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. 77, 760782 (2017). The land occupation ratio, defined by Eq. That's equivalent to 5 750 square miles, or around 0.1 percent of all the land the US has to offer. Denholm, P. & Margolis, R. M. Land-use requirements and the per-capita solar footprint for photovoltaic generation in the United States. (6): the further from the equator, the more space is needed between the different panels or heliostats to avoid self-shading, so the lower the packing factor. Change 122, 387400 (2014). (5), depends on the packing factor (PF) and the Generator-to-system area (GSR). Hernandez, R. R., Hoffacker, M. K. & Field, C. B. Science (80-. ) Drought, extreme heat, and flooding are wreaking havoc on your very means of survival: your land. The entire project features approximately 680,000 solar panels with an installed capacity of 272 MW, capable of generating about 400 GWh of clean energy annually which Vena said is up to 4% of . Solar PV capacity factors also vary based on location and technology, from 17 to 28 percent. Adeh, E. H., Good, S. P., Calaf, M. & Higgins, C. W. Solar PV power potential is greatest over croplands. The inclusion of a solar potential on identified wastelands in India (see Methods section) should have largely circumvented this inherent limitation in the applied method. This regime is based on a rationale of balancing cost minimisation (i.e. 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. Lopez, A., Roberts, B., Heimiller, D., Blair, N. & Porro, G. US Renewable Energy Technical Potentials: A GIS-Based Analysis. , 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. 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. 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. At 2580% penetration in the electricity mix of those regions by 2050, we find that solar energy may occupy 0.55% of total land. Hernandez, R. R. et al. The latter refers to emissions produced by using cropland for energy purposes and, therefore, indirectly increasing land competition elsewhere in the world to meet global food demand, potentially replacing land with high carbon stocks, such as natural forests7,8,9,10. 15, 32613270 (2011). 11, 6175 (1987). Clim. MITECO. 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. See Section 2 of the Supplementary Material (SM) for an overview of the scenarios designed for this study.
