addition to being the 28th largest oil producer; although the country has the Vaca Muerta field, which holds close to 16 billion barrels of technically recoverable shale oil, and is the second largest shale natural gas deposit in the world, the country lacks the capacity to exploit the deposit: it is necessary capital, technology and knowledge that can only come from offshore energy companies, who view Argentina and its erratic economic policies with considerable suspicion, not wanting to invest in the country. In renewable energies, in 2020, the country ranked 27th in the world in terms of installed wind energy (2.6 GW), 42nd in the world in terms of installed solar energy (0.7 GW) and 21st in the world in terms of installed hydroelectric power (11.3 GW). The country has great future potential for the production of wind energy in the Patagonia region. Chile, although currently not a major energy producer, has great future potential for solar energy production in the Atacama Desert region. Paraguay stands out today in hydroelectric production thanks to the Itaipu Power Plant. Bolivia stand out in the production of natural gas, where it was the 31st largest in the world in 2015. Ecuador, because it consumes little energy, is part of OPEC and was the 27th largest oil producer in the world in 2020, being the 22nd largest exporter in 2014. Transport Transport in South America is basically carried out using the road mode, the most developed in the region. There is also a considerable infrastructure of ports and airports. The railway and fluvial sector, although it has potential, is usually treated in a secondary way. Brazil has more than 1.7 million km of roads, of which 215,000 km are paved, and about 14,000 km are divided highways. The two most important highways in the country are BR-101 and BR-116. Argentina has more than 600,000 km of roads, of which about 70,000 km are paved, and about 2,500 km are divided highways. The three most important highways in the country are Route 9, Route 7 and Route 14. Colombia has about 210,000 km of roads, and about 2,300 km are divided highways. Chile has about 82,000 km of roads, 20,000 km of which are paved, and about 2,000 km are divided highways. The most important highway in the country is the Route 5 (Pan-American Highway) These 4 countries are the ones with the best road
