about 80% of the total production was for export. German companies poured €4.8 billion into Spain in 2015, making the country the second-largest destination for German foreign direct investment behind only the U.S. The lion's share of that investment —€4 billion— went to the country's auto industry. Energy In 2008, Spanish electricity consumption was an average of 6,523 kWh/person. Spanish electricity usage constituted 88% of the EU15 average (EU15: 7,409 kWh/person), and 73% of the OECD average (8,991 kWh/person). Spain is one of the world leaders in renewable energies, both as a producer of renewable energy itself and as an exporter of such technology. In 2013 it became the first country ever in the world to have wind power as its main source of energy. Agribusiness Agribusiness has been another segment growing aggressively over the last few years. At slightly over 40 billion euros, in 2015 agribusiness exports accounted for 3% of GDP and over 15% of the total Spanish exports. The boom was shaped during the 2004-2014 period, when Spain's agribusiness exports grew by 95% led by pork, wine and olive oil. By 2012 Spain was by far the biggest producer of olive oil in the world, accounting for 50% of the total production worldwide. By 2013 the country became the world's leading producer of wine; in 2014 and 2015 Spain was the world's biggest wine exporter. However, poor marketing and low margins remain an issue, as shown by the fact that the main importers of Spanish olive oil and wine (Italy and France, respectively) buy bulk Spanish produce which is then bottled and sold under Italian or French labels, often for a significant markup. Spain is the largest producer and exporter in the EU of citrus fruit (oranges, lemons and small citrus fruits), peaches and apricots. It is also the largest producer and exporter of strawberries in the EU. Food retail In 2020, the food distribution sector was dominated by Mercadona (24.5% market share), followed by Carrefour (8.4%), Lidl (6.1%), DIA (5.8), Eroski (4.8), Auchan (3.4%), regional distributors (14.3%) and other (32.7%). Mining In 2019, the country was the 7th largest producer of gypsum and the 10th world's largest producer of potash, in addition to being the 15th largest world producer of salt. Copper (of which the country is the second producer in Europe) is primarily extracted in the Iberian Pyrite Belt. The province of Granada features two
