A history of the British cotton industry

Jul 01, 2021Eighteenth-century machines typically used water power, hence the siting of early factories near the fast-flowing rivers of the Pennines. But after James Watt invented the steam engine in 1781, coal became the main fuel. Serendipitously, England's richest mines were also near the Pennines in Lancashire, Yorkshire, Nottinghamshire, and Derbyshire.

How Coal Works

Dec 15, 2017If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.

Hydroelectric Energy: The Power of Running Water

Dec 15, 2011Hydroelectric energy is made by moving water. Hydro comes from the Greek word for water. Hydroelectric energy has been in use for thousands of years. Ancient Romans built turbines, which are wheels turned by flowing water. Roman turbines were not used for electricity, but for grinding grains to make and breads. Water mills provide another source of hydroelectric energy.
