Final answer:
The United States consumes a significant amount of energy, using more than ten times the global average oil and gas consumption. Currently, the U.S. consumes about 30% of the world's total energy usage.
Step-by-step explanation:
The United States consumes a significant amount of energy. In the middle of the twentieth century, the U.S. used about 84% of global natural gas and 72% of petroleum, despite only having 6% of the world's population at that time. Americans used more than ten times the global average oil and gas consumption. Currently, the U.S. consumes almost 10 kJ per person per day, which is about 30% of the world's total energy usage.
