Coal and its importance in the past

Coal was the fuel that once kept the UK and many other countries running. Consequently this website has many mentions of how it impacted on the everyday lives of ordinary people. They are not limited to this page. Use the search box on the home page. This page is the introductory one. It describes what coal is, its advantages and disadvantages as a fuel, its huge range of uses in the past and why it is no longer the power house of so many countries. A feature is the contribution from a former coalman on the types of coal sold in the UK in the mid-20th century.

What coal is and its advantages in the past

Coal is a black or brownish-black sedimentary rock, high in carbon and hydrocarbons. This makes it burn well and at a higher temperature than wood logs or oil, and is why it used to be the main fuel in the UK, especially as the country had, and still has, large underground reserves. Digging it out, described as 'mining', was a necessary and significant source of employment.

Disadvantages of coal as fuel

In spite of the significant advantages of coal as a fuel, there were equally significant disadvantages. Burning coal produces dirty smoke and carbon dioxide which is dangerous to the environment and a major contributor to global warming and city fogs. Hence the current emphasis on alternative fuels and what is known as 'clean air' and 'net zero'.

Also, digging coal out from underground in coal mines was unpleasant and dangerous work.

Significant uses of coal in the past

Coal was by far the main source of energy in the UK up until the middle of the 20th century. It was used in the home for cooking on kitchen ranges, for heating on kitchen fires and for hot water in the copper. It was also converted into coal gas at local gasworks and in this form used for gas lighting and gas fires, later for gas ovens and much more. It was also the main industrial source of power.

Types of coal

There were different types of coal, depending on where it was mined and how it was treated above ground at the gas works. Most could be bought from the local coal yard.

Why is lignite missing from the list?

Older readers might wonder why lignite is missing from the list. The reason is that it is not actually coal. Lignite is a soft, brown sedimentary rock formed from peat. It is often classed as coal, in particular as brown coal, and is often burnt as coal even today.

However lignite is inferior in many respects to the UK's onshore seams of black coal. It burns at a lower temperature, has a higher moisture content and produces more smoke and fumes. Furthermore until the mid-20th century, the UK's far superior black coal was readily available. So there would not have been much call for lignite.

The beginning of the end for coal as a fuel

In 1956 the UK Government passed the Clean Air Act which legislated for zones where smokeless fuels had to be burnt instead of the polluting types of coal, and it relocated power stations to rural areas. Later acts legislated still further against air pollutants.

Consequently, no-one today knows what it was like to live and work in a real fog.
