Copper mining activity increased in the early 2000s because of increased price: the price increased from an average of $0.76 per pound for the year 2002, to $3.02 per pound for 2007. [2] A number of byproducts are recovered from American copper mining.
Production trends in the top five copper-producing countries, 1950-2012. This is a list of countries by mined copper production. Copper ore can be exported to be smelted so that a nation's smelter production of copper can differ greatly from its mined production. See: List of countries by copper smelter production.
Social Progress Index vs Energy Use per capita, 2015. List of countries by Social Progress Index. World energy consumption per capita based on 2021 data. This is a list of countries by total energy consumption per capita. This is not the consumption of end-users but all energy needed as input to produce fuel and electricity for end-users.
This is a list of U.S. states, U.S. territories, and the District of Columbia by exports of goods and imports of goods as of 2018. [note 1]An export in international trade is a good or service produced in one country that is bought by someone in another country.
The town went through boom periods during the two World Wars, when demand for copper went up again. By the time the mines closed in 1946, according to the U.S. Bureau of Mines, they had produced 72,598,883 pounds of copper worth over $12 million (equivalent to $193,000,000 in 2024). No copper mining has been done since.
California is the state with the largest population and the largest economy in the United States. It is second in energy consumption [2] after Texas. [3] As of 2018, per capita consumption was the fourth-lowest in the United States partially because of the mild climate and energy efficiency programs. [4]
Hence, the upper third of all places in this ranking have a per capita income with a lower bound roughly equal to that of the state, about $30,000. The median place and county in California had a per capita income of roughly $25,000, and the lower third of both types of geographies had per capita incomes with an upper bound of about $20,000.
The country had a per capita energy consumption of 295 million BTU (311 GJ), ranking it tenth in the world behind Canada, Norway, and several Arabian nations. [4] Consumption in 2023 was mostly for industry (33%) and transportation (30%), with use in homes (20%) and commercial buildings (17%) making up the remainder.
