Energy has a long history. Beginning back before people could read and write, fire was discovered to be good for cooking, heating and scaring wild animals away. Fire was civilization's first great energy invention, and wood was the main fuel for a long time. Famous People in Energy made this history. The history of "Energy in the United States, 1635-2000", traces a more recent story.

Wood (Biomass) | ||
Pre-1885 | Wood was the primary source for cooking, warmth, light, trains and steamboats. Cutting wood was time consuming, hard work. | |
Electricity | ||
1700's | After eons of superstitious imaginations about electricity, Ben Franklin figured out that static electricity and lightening were the same. His correct understanding of the nature of electricity paved the way for the future. | |
1830-1839 | Michael Faraday built an induction dynamo based on principles of electromagnetism, induction, generation and transmission. | |
1860’s | Mathematical theory of electromagnetic fields was published. Maxwell created a new era of physics when he unified magnetism, electricity and light. One of the most significant events, possibly the very most significant event, of the 19th century was Maxwell's discovery of the four laws of electrodynamics ("Maxwell's Equations"). This led to electric power, radios, and television. | |
Coal | ||
1763-1774 | Pumping water from coal mines was a most difficult and expensive problem. The steam engine developed by James Watt during these years provided the solution. Watt's steam engine remained basically unchanged for the next century and its uses expanded to change the whole nature of industry and transportation. | |
1885-1950 | Coal was the most important fuel. One half ton of coal produced as much energy as 2 tons of wood and at half the cost. But it was hard to stay clean in houses heated with coal. | |
Late 1860’s | The steel industry gave coal a big boost. | |
1982 | Coal accounted for more than half of the supply of electricity but little was used in homes. In terms of national electricity generation, hydropower, natural gas, and nuclear energy contributed between 10 and 15 percent each. | |
Oil | ||
By 1870 | Oil had become the country’s second biggest export after the industry was started by Edwin Drake. | |
1890 | Mass production of automobiles began,creating demand for gasoline. Prior to this, kerosene used for lighting had been the main oil product. | |
1951-present | Oil has given us most of our energy. Automobiles increased the demand for oil. | |
1960 | The Organization of Petroleum Exporting Countries (OPEC) was formed by Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The group has since grown to include 11 member countries. | |
1970 | U.S. production of petroleum (crude oil and natural gas plant liquids) reached its highest level at 11.7 million barrels per day. Production in the Lower-48 States has been generally declining since 1970. Some of this decline has been offset by increased Alaskan production after 1978. | |
1993 forward | For the first time the U.S. imported more oil and refined products from other countries than it produced. More and more imports have been needed because of growing petroleum demand and declining U.S. production | |
Nuclear | ||
1906 | Special theory of relativity written. Albert Einstein created a new era of physics when he unified mass, energy, magnetism, electricity, and light. One of the most significant events, if not the very most significant event, of the 20th century was Einstein's writing the formula of E=mc2: energy = mass times the square of the speed of light. This led to nuclear medicine - and a much longer life span, astrophysics, and commercial nuclear electric power | |
1942 | Scientists produced nuclear energy in a sustained nuclear reaction. | |
1957 | The first commercial nuclear power plant began operating. | |
1995 | Nuclear power contributed about 20 percent of the nation's electricity. |
Transportation | ||
1781 | The stagecoach was the worldwide standard for passenger travel. | |
1800 | Transportation as we know today was almost non-existent. Railroads covered far less territory. Trains were much smaller. Horse-drawn carts moved food and all other items on land, and barges moved them on rivers. | |
1881 | The steam-powered railway train had become the worldwide standard for passenger travel. | |
1908 | Henry Ford produced the Model T car (Note that the Model T had been designed to use ethanol, gasoline, or any combination of the two fuels). | |
1920 | The Ford Motor Company manufactured the Model T in large numbers. | |
1949-2000 | In transportation, use of energy is overwhelmingly petroleum. Energy for this use more than tripled from 1949 to 2000, with motor gasoline accounting for about two-thirds of it. Distillate fuel oil and jet fuel are other important petroleum products used in transportation. | |
1950-present | The National Highway Defense System opened interstate highways for fast trucks. | |
Energy Uses Have Changed | ||
1800 | The residential sector consumed most of America's energy. | |
1850-1980 | The average energy that each person used increased steadily. | |
1979-1982 | Energy consumption decreased ten percent. The industrial sector cut its consumption by 20 percent. The residential and commercial sectors energy consumption stayed about the same. | |
1950 | Distillate fuel oil heated about 22 percent of U.S. households. Over a third of all U.S. housing units were warmed by coal. Natural gas was used to warm about 25 percent of U.S. households. Electricity was used to warm only 0.6 percent of U.S. households. | |
1978 | Microwave ovens were located in 8 percent of U.S. households. | |
1990 | 16 percent of households owned one or more personal computers. | |
1997 | Only about 11 percent of all U.S. housing
units were warmed by distillate fuel oil. Only 0.2 percent of all U.S. housing units were warmed by coal. More than 50 percent of all U.S. households used natural gas for warmth. Electricity was used for 29 percent of U.S. households used for warmth. 35 percent of U.S. households had personal computers. Microwaves could be found in 83 percent of U.S. households. 99 percent of U.S. households had a color television. 47 percent had central air conditioning. 85 percent of all households had one refrigerator, the remaining 15 percent had two or more. |
