The line graph provides past, present and future data of American energy production as well as its consumption over the course of 76 years between 1950 and 2025. All figures are measured in quadrillions of British Thermal Units and collected every 25 years.
Through out the given timeline, the North American country has increasingly consumed more energy than it can produce, with the power shortage, which will be tackled by imports, being predicted to worsen into the first quarter of the 21st century.
In 1950, 25 units of energy were produced while 1unit had to be imported to compensate for national power usage. This was followed by fluctuations in the next few years, with differences ranging between roughly 35 and 45 units before surging to 60 units and 65 units for production and consumption respectively by 1975, during which approximately 10 units had always been demanded from imports. A similar trend was observed in the last quarter of the 20th century, witnessing energy demands soar to 95 units whereas only as many as 70 units were supplied.
Since 2000, it has been projected that the need for more power in the USA will continue to rise when production can only supply another 90 units maximum until 2025 despite a foreseen demand of 140 units by the same year, resulting in a lack of 50 units that have to come from energy imports.
