- Total US primary energy consumption by year, 1635–2000. Pre-1949 data covers selected years at irregular intervals (decennial 1635–1845, quinquennial 1850–1945). Annual data from 1949. Gap exists for 1946–1948 (bridging period between historical and modern EIA series). Values in quadrillion Btu (1 quad = 10^15 Btu = 1.055 exajoules).

About this dataset
US Primary Energy Consumption 1635–2000
Estimated primary energy consumption in the United States from 1635 to 2000. Covers 365 years of US energy history — from wood and water power in the colonial era, through the coal-dominated industrial revolution, to the rise of petroleum and natural gas in the 20th century.
Data
| File | Description | Coverage |
|---|---|---|
data/primary-energy-consumption.csv | Total primary energy consumption | 1635–2000 |
data/primary-energy-by-source.csv | Breakdown by fuel type | 1850–1945 (selected years) |
All values in quadrillion Btu (quad Btu). 1 quad Btu = 10¹⁵ Btu ≈ 1.055 exajoules.
Coverage notes
- 1635–1845: Decennial selected years. Colonial and early republic era — almost entirely wood fuel and water power.
- 1850–1945: Quinquennial selected years. Covers the industrial revolution and rise of fossil fuels. Source breakdown available.
- 1946–1948: Gap in published EIA series (bridge between historical and modern datasets).
- 1949–2000: Annual data from EIA Monthly/Annual Energy Review. Full energy system including nuclear from ~1957.
Key milestones
| Year | Event |
|---|---|
| 1850 | Coal begins appearing in energy mix (0.219 quad) |
| 1880s | Natural gas first recorded |
| ~1900 | Coal surpasses wood as primary energy source |
| ~1950 | Petroleum surpasses coal |
| 1957 | Nuclear energy enters the grid |
| 1970 | Peak consumption growth era: 67.8 quad Btu |
| 1973–74 | Oil crisis: consumption falls from 75.7 to 74.0 quad Btu |
| 2000 | US consumes 98.8 quad Btu — the highest to that point |
