The History Of Energy

I wrote most of this dkospedia article some time ago, and am reprinting it here as I looked at it today as a reference and find it still useful..

This article is placed in dKospedia to overcome the tendency of policy makers to ignore the fact that our fossil fuel Energy economy is relatively recent and that the technology underpinnings of society are capable of changing rapidly when circumstances and technology drive such a change.

Ancient History

Prior to 1807, if you wanted to travel by water, your choices were sailing, rowing, or taking a barge that flowed with the current or was pulled by animals upstream. The Erie Canal completed in 1825, was one of the last major construction projects in the old paradigm. It featured barges pulled through canals by animals to connect the Hudson river to Lake Erie. If you wanted to travel overland, prior to 1825, you could walk, ride a horse, or ride in an animal or person drawn carriage or wagon.

If you wanted to heat your home, you typically used wood or charcoal, and even some coal burned directly for heating and cooking. There were isolated instances where geothermal power was used to heat homes. A few small communities in China used natural gas to desalinate water. Animal and vegatable oils and waxes were used for lamps. Hot water came from the fire under your stove. Wind power and water power was principally used to power water wells and grain mills.

Of course, commercial use of electricity, nuclear power, oil wells, widespread use of natural gas and the like were in the distant future.

The Industrial Revolution and Coal

If you wanted to date the start of the industrial revolution, 1769, when James Watt patented his refinements of the steam engine, that brought steam engines from 5% to 25% efficiency, would be as good a date as any. He also built the first steam wagon, which is arguably the first automobile, that year, but the automobile didn't become practically viable for another century plus. (Papin build the first modern working model of a steam engine in 1679, Savery built a steam engine in 1698 and Newcomen built a steam engine in 1712 that Watt would refine into something commercially viable).

We call it a “steam economy”, but the terms "steam engine", "steam boat", "steam ship" and "steam locomotive", are all code words. The industrial revolution and all of its steam powered machinery was powered by coal. From the mid-19th century to the mid-20th century, there were coal powered trains, boats and even motor vehicles. Coal was a major fuel for heating. Coal still provides the majority of our electricity. But, since the 1950s, when the last coal power railroad engines (such as the "Big Boys") were phased out, coal has been used almost exclusively in power plants and industry.

The steam powered train prevailed for about a century and a half from 1804, when the first steam locomotive was built in Wales (although commercial steam train service wasn't in place until 1825), until the 1950s when the last steam locomotives were starting to be phased out by diesel and diesel-electric models. Today, coal powered trains are used commercially only in China, although steam trains are still operated as historic tourist destinations in a number of locations.

The steam powered riverboat dates to 1807 when Fulton began operating one on the rivers of the United States. The first steam ship to cross the Atlantic did so in 1819, with regular commercial service starting in 1838. The Queen Elizabeth passenger liner built in 1938 was the largest steam ship ever built. The last major steam ship ever built was the Queen Elizabeth 2 cruise liner in 1968, which was converted to diesel in 1986.

By the early 20th century, radiators powered by coal or oil fired boilers brought heat to most homes. Many older homes have coal chutes that reflect this period in our technological history. (This also coincided with the "ice boxes" which were common before electricity and related technologies made home refrigerators common).

In its early days, coal produced massive amounts of soot that covered everything. Victorian era glass covered bookshelves, for example, were built so that you didn't have to dust the books daily to remove the coal dust. Modern coal plants are cleaner, but still produce large amounts of waste. Today's heavily coal dependent China experiences many of the soot problems common in the pre-environmental regulation coal fuel era in the Western world.

Peak coal is nowhere near. We have a 300 year supply of coal at current use rates with current technologies. In fact, the coal supply would almost certainly last longer than that at that useage rate, because technology will almost certainly advance over the next 300 years making more coal available for consumption. But, oil has proved easier to use for transportation applications, and natural gas burns cleaner and can be brought to homes by inexpensive pipelines.

Diesel and Gasoline

The first commercial oil well was built in Petrolia, Canada in 1858, which was the leading producer of mineral based oil in the world until 1901 when oil was found in Texas. But, oil did not see widespread comercial use until the early 20th century when the internal combustion engine in the automobile became widespread.

In the late 19th century, ethanol (starting in the 1890s) and electric cars were developed. But, prohibition in the United States in 1919 wiped out the ethanol industry, and efforts to create an automotive industry in Britain were stimied until 1896 by the "red flag law" which prevented vehicles from operating unless someone on foot with a red flag and noisemaker announced the coming of the motor vehicle.

In 1886 gasoline powered internal combustion engines were developed. The first gasoline powered automobile in mass production, the Oldsmobile, dates to 1902. A decade later, beginning with the rise of Ford's Model T and subsequent models, gasoline and to a lesser extent diesel became the dominant fuel for automobiles.

The Wright Brothers flew the first heavier than air airplane in 1903. Heavier than air flight was based on petroleum based fuels from the beginning. Marine diesel engines began around 1912 and only a handful of steam ships were built after 1960. Diesel locomotives for trains became common starting in the 1920s, and had virtually completely replaced the steam engine by the 1960s. Most trains now operate with either hybrid diesel-electric engines or with electricity from a third rail or overhead electrical source.

Heating oil was once a major means of heating homes, but now this is restricted largely to the Northeast, Alaska and Hawaii. Heating oil continues to decline in popularity in the Northeast. Natural gas and electricity are the dominant home heating methods today and this has been increasingly the case since at least the 1950s.

Gasoline is the dominant fuel for household and light commercial vehicles in the United States, although all tolerate some ethanol and a large part of the European market is diesel based. Diesel is the dominant fuel for military vehicles, trucks, trains, boats, and ships in the United States. Virtually all aircraft run on some oil based fuel (most jet fuel is a form of kerosene). A few trucks and buses run on alternative fuels (such as natural gas), a few urban and high speed trains are electrically based, and a few aircraft carriers and submarines are powered by nuclear rather than fossil fuels.

Gasoline has slightly higher energy density than diesel and emits fewer particulates and NOx pollutants, but gets lower mileage. (Gasoline engines use less compression and an electric starter, while diesel engines use greater compression eliminating the need for an electric starter and thus simplying the engine). Tax incentives in Europe favor diesel and modern diesel engines are cleaner than their predecessors, while regulations to eliminate sulfur from diesel fuel will make it possible to use more effective exhaust cleaning technologies for diesel vehicles. The United States was just on the verge as of 2005 of taking similar steps to remove sulfur from diesel fuels.

Some put the time period until Peak Oil at 40 years. Others are more optimistic (in part as a result of grossly incorrect predictions of early peak oil dates made in the 1970s during the energy crisis). But, almost all industry analysts do see a long term trend towards more expensive petroleum products, as demand rises with world economic development, and the cheapest supply sources are exhausted. There are few places in the world where major new oil supplies could be discovered.

Natural Gas

Natural gas was first used for illumination, primarily in gas street lights, in 1785 in Britain and in 1816 in the United States. The first natural gas well was built in 1821 in Fredonia, New York, and, in 1859, natural gas was first produced in the United States on an industrial basis. Natural gas was used almost exclusively for illumination through the late 19th century. The Bunsen Burner (which allowed natural gas to be used for water heating and cooking purposes) was invented in 1885, and the first major pipeline was built in 1891. A significant pipeline industry began in the 1920s. More reliable pipelines were constructed from 1945 to the 1960s. These pipelines made home heating, water heating, cooking and other modern uses of natural gas possible. Prior to development of these uses of natural gas, it was simply flared from oil wells. Flaring remains common today in areas where a lack of pipelines makes natural gas unprofitable, but for environmental and long term economic reasons, pumping natural gas back into oil wells is the preferred practice.

Limited efforts have been made since the 1970s to explore natural gas as a vehicle fuel, but concerns about the fact that natural gas is not renewable, and technological and infrastructure challenges, have held back this kind of development outside isolate fleet vehicle uses. Those vehicles in service which do use natural gas perform similarly to conventional vehicles and are less polluting than gasoline or diesel powered vehicles.

Peak natural gas is expected to come later than Peak Oil by at least a decade, but again, there are widespread disagreements over how much natural gas is left. Industry sources generally claim the proven reserves of natural gas account for less than 10% of the actual commercially exploitable supply.

Water Heating

Prior to the 1920s, home water heating was pretty much confined to boiling water over a coal or wood fire. Some parts of the world developed public baths (e.g. in Rome, Greece, Turkey and Bath, England) around either natural hot springs, or elaborate coal or wood based water heating systems. The 1920s brought dedicated coal fired water heaters and water heaters integrated with a kitchen stove. Natural gas and electricity are now the dominant means of powering home water heaters.


While scientists were starting to understand electricity around 1800, the first commercially viable use of electricity came when Edison invented electric lighting in 1878, as a replacement to gas powered lamps. In 1880, the Edison electric company started to electrify buildings in New York City (for lighting only). By 1886, electric fans, as well as electric lighting was made possible. The Edison plan was based on direct current. Around the same time, early automobile makers were tinkering with electric cars (but the gasoline and diesel powered internal combustion engines quickly eliminated this development for the next century).

The first alternating current plant was developed by Tesla in Telluride, Colorado in 1891. This was followed by a similar AC power plant opened by Niagara Power in 1895 which provided power for industrial aluminum works in Buffalo, New York in 1895. In 1907 about 8% of dwellings had electricity (overwhelmingly in urban areas). By 1932, about 80% of urban homes and about 11% of farm homes (about 67% overall) had electricity. By 1941 the work of the New Deal rural electrification administration had brought electricity to about 35% of farm homes. This reached about 50% in 1945 and about 80% of rural homes in 1950.

Nuclear Power

Enrico Fermi established the first controlled nuclear fission reaction on December 2, 1942 at the University of Chicago. An experimental 600 watt nuclear power plant was brought on line December 20, 1951 under the watchful eye of President Eisenhower's newly established Atomic Energy Commission. The first reasonable scale nuclear power plant was the BORAX III plant that began producing power for Arco, Idaho on July 17, 1955. The first commecial nuclear power plant operated in Shippingport, Pennsylvania from 1957 to 1982.

All 108 nuclear power plants now operating in the United States, and several which have since been shut down or converted from nuclear to conventional fuels, were ordered between 1955 and 1974. These plants now provide about 20% of the electricity in the United States. About 97 plants were contracted for and cancelled, mostly as a result of the accident at Three Mile Island and related concerns about safety and waste disposal. The fact that nuclear power plant projects have been plauged with cost overruns, in part because each one has been custom built from scatch, has also been a factor. See here for detailed historical information.

There have been about 37 nuclear powered surface ships built (the first was launched in 1959), all but three by the United States and the Soviet Union. Most have been for military purposes, although three commercial nuclear powered ships, none of which are currently in service, and a number of icebreakers, have also been built. Several dozen nuclear submarines have also been built, the first of which was completed in 1954.

Nuclear fusion has been proposed as a source of nuclear power, but while it has proven technologically feasible to use fusion in bombs and it powers the Sun, it has not yet been developed to the point of being commercially viable. An experiment which researchers had hoped would make for cheap and easy power through nuclear fusion called Cold Fusion has not been replicated, although it generated a great deal of interest when it was announced.

Renewable Energy in the Modern Era

Renewable forms of energy have by far the most ancient lineage. Biofuels are as old as the intentional use of fire by humanity by our pre-Home Sapiens ancestors. Wind power and water power were used before electricity, steam engines and internal combustrial engines were invented. Geothermal power from hot springs has been used to provide baths from Rome to Glenwood Canyon, Colorado to New Zealand for millenia. But, modern interest in renewable energy took new urgency after the Energy Crisis that the United States experienced in the 1970s as a result of the Organization of Petroleum Exporting Countries oil embargo established as a response to concerns held by Arab Countries over policies relating to Israel.

So should we go back to using renewable resources like wood to heat (and cool and light) our homes? Because I think that would produce quite a bit of polution. And how many forests would we have to clearcut each year?

Gas and coal are what work now. In the past, wood and animal fats worked the best. In the future, something else will work the best. But for now, I'll stick to my Regular Unleaded and hydroelectric power. (Seattle's electric usage listed below:

Hydro 86.45%
Natural Gas 5.28%
Nuclear 4.23%
Wind 3.06%
Coal 0.89%
Biomass 0.07%
Petroleum 0.02%)

Right now, a combination of conservation, nuclear and wind power are probably the best options (hydropower is not available in much of the nation) for electricity.

Technologies like LEDs to reduce electricity demand have huge potential. Insulation can greatly reduce A/C demand (not that you need much of that in Seattle).

Solar is probably best in the niche of peak electricity supply for air conditioning in places like Arizona, and in water heating and passive solar applications.

For transportation -- developing freight rail, developing passenger rail in high density corridors, developing bus service in lower density corridors, and going first to smaller vehicles (especially for commuting) and hybrids, while ultimately going pure electric for intracity traffic, is probably the way to go. Biofuels have their place, but ultimately should be for fueling absolutely necessary intercity traffic away from rail lines in rural areas.

"Some put the time period until Peak Oil at 40 years. Others are more optimistic (in part as a result of grossly incorrect predictions of early peak oil dates made in the 1970s during the energy crisis)."

Actually, this is a popular misconception; when one says "peak oil" it is referring to worldwide oil production peaking, as in producing the maximum per day that it is ever going to given the circumstances with the world's mature oil fields depleting and new discoveries getting smaller as well as in less-accessable areas as you said. In short, the time of "peak oil" is not when the world RUNS OUT of oil, but rather the time when it's producing the most it can realistically be expected to produce each day and can only from there decline over the course of decades as existing oil fields are exhausted and new finds are smaller and less frequent, discovery having reached its own peak in 1965 and declining ever since.

Given the circumstances just mentioned and also given that world daily oil production seems to be on a plateau over these last few years, it would appear that oil production is about maxed out now. Meaning "peak oil" is about now, give or take a couple years. What some are saying with the forty years is that at current rates of consumption the world might have forty years of crude LEFT. At any rate, as we slip off of the "peak" plateau down the other side oil will get more and more expensive before "demand destruction" has any appreciable effect. And it will still be increasingly scarce over the coming few decades. Though nobody's saying the oil is going to be gone tomorrow, it most certainly is the end of the era of cheap oil. Until the world's main auto fuel has a source that's renewable and doesn't impact the food supply, like ethanol made from wood chips instead of corn, development will be tied to an anchor and no amount of new discoveries, drilling in ANWR, oil shale barbecue science projects etc. are going to be able to restore the situation. The time to begin getting the infrastructure in place for something beyond crude oil-derived fuels is now, which is surely the point you're making anyway. And regardless I agree with the rest of your article, I just had to point out that detail about the peak oil matter, not trying to be rude. Nice blog and I'll be back to visit later.
