$6 trillion
Solar energy provides four-tenths of 1 percent of the total energy consumed in the United States. While the amount of solar electricity capacity in the US has increased in recent years, it still only accounts for 0.4% of net utility-scale electricity generated in the United States.  The majority of this energy is derived from fossil fuels: in 2010, data showed 25% of the nation's energy came from petroleum, 22% from coal, and 22% from natural gas. From the beginning of the United States until 1973, total energy (including electrical) use increased by about 3%/year, while population increased an average of 2.2%/year. Per capita energy use from 1730 to 1870 was about 100 million Btu/person. The statistic represents U.S. energy consumption in 2013 and 2014, with a breakdown by energy source. In the United States consumed some 28 quadrillion British thermal units of energy derived from natural gas in 2014. Energy consumption by source. Petroleum is the main source of energy in the United States. Despite the prevalence of fossil fuels in the U.S. energy mix, the use of renewable energy sources has grown from around 16.8 million metric tons of oil equivalent in 2001 to a little under 60 million metric tons of oil equivalent in 2013. According to the Energy Information Administration 's statistics, the per-capita energy consumption in the US has been somewhat consistent from the 1970s to today. The average has been 334 million British thermal units (BTUs) per person from 1980 to 2010. From the beginning of the United States until 1973, total energy (including electrical) use increased by about 3%/year, while population increased an average of 2.2%/year. Per capita energy use from 1730 to 1870 was about 100 million Btu/person. The United States is the 2nd largest energy consumer (after China) in terms of total use in 2010. The U.S. ranks seventh in energy consumption per-capita after Canada and a number of small nations. From the beginning of the United States until 1973, total energy (including electrical) use increased by about 3%/year, while population increased an average of 2.2%/year. Per capita energy use from 1730 to 1870 was about 100 million Btu/person. Energy Productivity in the United States economy has increased by 11% from 2007 to 2014. 7. It is estimated by the Bureau of Labor and Statistics that there are more than 3.4 million jobs in the United States related to clean energy initiatives. It is estimated that in 2014, the United States used approximately 412 billion kWh of electricity just for lighting. 17. The United States uses approximately 23% of the world’s energy, yet it only holds about 5% of the world’s population. 18. K-12 schools in the United States spend more than $6 billion on energy use, or more than they spend on textbooks and computers combined. 19 The United States is one of the world’s leaders in energy supply, production and consumption. Today, America has one of the most diverse energy markets in the United States and is one of the leaders in the $6 trillion global energy market. It is estimated that in 2014, the United States used approximately 412 billion kWh of electricity just for lighting. 17. The United States uses approximately 23% of the world’s energy, yet it only holds about 5% of the world’s population. 18. K-12 schools in the United States spend more than $6 billion on energy use, or more than they spend on textbooks and computers combined. 19 The average individual daily consumption of water is 159 gallons, while more than half the world's population lives on 25 gallons. Fifty percent of the wetlands, 90% of the northwestern old-growth forests, and 99% of the tall-grass prairie have been destroyed in the last 200 years. Eighty percent of the corn grown and 95% of the oats are fed to livestock. Fifty-six percent of available farmland is used for beef production. The population is projected to increase by nearly 130 million people-the equivalent of adding another four states the size of. - by the year 2050. Forty percent of births are unintended. Americans eat 815 billion calories of food each day-that's roughly 200 billion more than needed-enough to feed 80 million people. Energy Consumption. Statistics and facts on Energy Consumption in the U.S. As emerging countries continue to grow rapidly, the world’s total energy demand keeps rising. The growing demand is largely covered by fossil fuels, namely petroleum, coal and natural gas
