Alexis de Tocqueville (1805-1859) – French political thinker and historian best known for his Democracy in America – wrote: “The country appears to stretch on forever and is of limitless resources. But, no matter how fast it grows, it will remain surrounded by resources it cannot possibly exhaust.”
Energy: The United States has more coal reserves than any other country in the world and represent one-quarter of the world’s total coal supply. The U.S. has 272 billion tons of coal reserves and uses about 1.1 billion tons of coal per year. At this rate, America’s 272 billion tons of coal reserves would last nearly 250 years.
According to the 2012 article “American Oil Growing Most Since First Well Signals Independence“ by Asjylyn Loder on bloomberg.com domestic output of oil grew by a record 766,000 barrels a day to the highest level in 15 years, government data shows, putting the nation on pace to surpass Saudi Arabia as the world’s largest producer by 2020.
Net petroleum imports have fallen by more than 38 percent since the 2005 peak, and now account for 41 percent of demand, down from 60 percent seven years ago, moving the United States closer to energy independence than it has been for decades.
Key natural resources: One-third of U.S. land is covered by forests (302 million hectares), making forestland the number one type of land use in the United States. One-fifth of U.S. land is timberland (204 million hectares), which is land capable of producing 1.38 cubic meters per hectare of industrial wood annually. 71 percent of all timberland in the U.S. is privately owned, while 29 percent is publicly owned.
Land: The United States has a land area of 3.8 million miles² (9.8 million km²) compared to 9.7 million km² in China, 0.36 million km² in Germany and 0.38 million km² in Japan.
Population density: United States population density per square mile is 84, compared to 365 for China, 609 for Germany, and 836 for Japan.
