Chile's energy consumption is dominated by its mining sector, which accounts for about 35 percent of total consumption. Mining is the country's main source of income, and copper is by far the most important ore mined in Chile; the country possesses nearly 30 percent of the world's reserves and is the foremost global producer. The copper industry alone represents 13.5 percent of the Chilean gross domestic product — a figure that has more than doubled in 10 years, mainly due to East Asia's sharply increasing demand for the commodity. To match the expected growth in global demand and to counterbalance the rising competition from regional and international producers, the Chilean government has set the goal of producing 7 million metric tons of copper annually by 2020, up from 5.3 million in 2010. However, this goal may prove to be overambitious because of the shortage of cheap energy.
