Worldwide, there are an estimated nine million acres (about thirty-six and a half thousand square kilometers) of greenhouses.<ref>{{cite news|last1=McNutty|first1=Jennifer|title=Solar greenhouses generate electricity and grow crops at the same time, UC Santa Cruz study reveals|url=https://news.ucsc.edu/2017/11/loik-greenhouse.html|access-date=6 November 2017|work=USC Newscenter|publisher=University of California |location=Santa Cruz|date=3 November 2017}}</ref>

The [[Netherlands]] has some of the largest greenhouses in the world. Such is the scale of food production in the country that in 2017, greenhouses occupied nearly 5,000 hectares.<ref>{{Cite web |last=Netherlands |first=Statistics |title=Upscaling of greenhouse vegetable production |url=https://www.cbs.nl/en-gb/news/2018/16/upscaling-of-greenhouse-vegetable-production |access-date=2022-06-10 |website=Statistics Netherlands |date=18 April 2018 |language=en-GB}}</ref>

Greenhouses began to be built in the [[Westland (region), Netherlands|Westland region]] of the Netherlands in the mid-19th century. The addition of sand to bogs and clay soil created fertile soil for agriculture, and around 1850, grapes were grown in the first greenhouses, simple glass constructions with one of the sides consisting of a solid wall. By the early 20th century, greenhouses began to be constructed with all sides built using glass, and they began to be heated. This also allowed for the production of fruits and vegetables that did not ordinarily grow in the area. Today, the Westland and the area around [[Aalsmeer]] have the highest concentration of greenhouse agriculture in the world.<ref>{{Cite web |title=Greenhouse farming Guide for Beginners (2024) |url=https://www.agriculturelandusa.com/2024/01/greenhouse-farming-beginners-guide%20.html |access-date=2024-02-18 |website=Agriculture land usa}}</ref> The Westland produces mostly vegetables, besides plants and flowers; Aalsmeer is noted mainly for the production of flowers and potted plants. Since the 20th century, the area around [[Venlo]] and parts of [[Drenthe]] have also become important regions for greenhouse agriculture.

Since 2000, technical innovations have included the "closed greenhouse", a completely closed system allowing the grower complete control over the growing process while using less energy. Floating greenhouses are used in watery areas of the country.

The Netherlands has around 4,000 greenhouse enterprises that operate over 9,000 hectares<ref>{{cite web|url=http://statline.cbs.nl/Statweb/publication/?VW=T&DM=SLNL&PA=80780NED&D1=295-296,299-300,303,305,309,311,317,320-321,323,326-327,332,338-339,360,363-364&D2=0&D3=0,5,(l-2),(l-1),l&HD=150529-1850&HDR=G1,G2&STB=T|title=  gewassen, dieren en grondgebruik naar regio|publisher=CBS StatLine – Landbouw|access-date=10 July 2016}}</ref> of greenhouses and employ some 150,000 workers, producing €7.2 billion<ref>{{cite web|url=http://statline.cbs.nl/Statweb/publication/?VW=T&DM=SLNL&PA=80785NED&D1=a&D2=a&D3=0-1,7,17,21,30,38,40,43&D4=0,7,13-14&HD=150529-1858&HDR=T,G3&STB=G2,G1|title= economische omvang naar omvangsklasse, bedrijfstype|publisher=CBS StatLine – Landbouw|access-date=10 July 2016}}</ref> worth of vegetables, fruit, plants, and flowers, some 80% of which is exported.{{Citation needed|date=December 2011}}<ref>{{cite web|url=https://www.fastcompany.com/90476025/these-eerily-beautiful-glowing-buildings-are-the-netherlands-massive-network-of-greenhouses |title=See the Netherlands' massive network of greenhouses from above |publisher=Fastcompany.com |date=13 March 2020 |author=Peters, Adele |work=Fast Company |accessdate=22 June 2021}}</ref><ref>{{cite web|url=https://www.dw.com/en/could-high-tech-netherlands-style-farming-feed-the-world/a-47105412 |title=Could high-tech Netherlands-style farming feed the world? |work=Deutsche Welle |date=23 January 2019 |accessdate=22 June 2021}}</ref>
