As of 2002, Alaskan production of crude oil was 17% of the nation's total, and, at 984,000 barrels per day, 2nd only to that of Texas. The Trans-Alaska Pipeline runs 789 mi (1,270 km) from the North Slope oil fields to the port of Valdez on the southern coast. Most of Alaska's energy products are produced and refined locally. The state's six refineries have a combined crude distillation capacity of 357,000 barrels per day. Proved reserves as of 2001 totaled 4.85 billion barrels, or about 22% of national reserves.
Marketed natural gas production in 2002 was 464.7 billion cu ft (13.2 billion cu m). In 2001, proved reserves were 8.8 trillion cu ft (0.25 trillion cu m). Total electric power production (utility and nonutility) was over 5.8 billion kWh in 1999; total installed capacity was over 2 million kW, and almost all generating facilities were government owned. Alaska has no nuclear power plants.
Alaska also had proved coal reserves totaling 6.5 billion tons in 1996 (more recent figures have been withheld to avoid disclosure of company data). Production of coal in 2000 was 1,641,000 tons, from a single mine at Healy. In 2000 Alaska ranked first among the states in per capita energy consumption, with a total of 944 million Btu (237.9 million kcal).
