Patagonia's notorious winds have already made the area Argentina's main source of wind power, and plans have been made for major increases in wind power generation. Patagonia has always been Argentina's main area, and Chile's only area, of conventional oil and gas production. Oil and gas have played an important role in the rise of Neuquén-Cipolleti as Patagonia's most populous urban area, and in the growth of Comodoro Rivadavia, Punta Arenas, and Rio Grande, as well.
