Historically, windmills in Holland served many purposes. The most important probably was pumping water out of the lowlands and back into the rivers beyond the dikes so that the land could be farmed. In the fourteenth century, hollow-post mills were used to drive scoop wheels to drain the wetlands.
-
"The mill reached its greatest size and its most efficient form in the hands of the Dutch engineers toward the end of the sixteenth century... The Dutch provinces... developed the windmill to the fullest possible degree: it ground the grain produced on the rich meadows, it sawed the wood.

"Experimenters... discovered that the roasting process used to make charcoal [from wood] could be adapted to coal, the result being an extremely hot-burning fuel called coke. The use of coke in iron and steel production, beginning in England in the 17th century, would so transform those industries as to constitute one of the key developments paving the way for the industrial revolution."

"The great shift in population and industry that took place in the eighteenth century was due to the introduction of coal as a source of mechanical power, to the use of new means of making that power effective - the steam engine - and to new methods of smelting and working up iron. Out of this coal and iron complex, a new civilization developed.

"By 1700 [coal] mine shafts were as deep as 200 feet. There were problems down there with gases and especially with flooding... Muscle, animal and human, and sometimes watermills and windmills were put to work lifting the water out of the mines, but it was an endless battle that technology circa 1700 could not win.

The first coal 'miners' in the American colonies were likely farmers who dug coal from beds exposed on the surface and sold it by the bushel. In 1748, the first commercial coal production began from mines around Richmond, Virginia. Coal was used to manufacture shot, shell, and other war material during the Revolutionary War.
-
"In 1701, coal was found by Huguenot settlers on the James River in what is now Richmond, Virginia. By 1736, several 'coal mines' were shown on a map of the upper Potomac River near what is now the border of Maryland and West Virginia.

"English scientists William Nicholson and Sir Anthony Carlisle discovered that applying electric current to water produced hydrogen and oxygen gases. This process was later termed 'electrolysis.'" The discovery of electrolysis was an important historical step in the development of hydrogen energy and the hydrogen fuel cell.

"In 1821, the first well specifically intended to obtain natural gas was dug in Fredonia, New York, by William Hart. After noticing gas bubbles rising to the surface of a creek, Hart dug a 27 foot well to try and obtain a larger flow of gas to the surface. Hart is regarded by many as the 'father of natural gas' in America.

"The first major boon for coal use occurred in 1830 when the Tom Thumb, the first commercially practical American-built locomotive, was manufactured. The Tom Thumb burned coal, and in rapid fashion, virtually every American locomotive that burned wood was converted to use coal. America's coal industry had begun taking shape."

"The modern oil industry was born on a hill in southeastern Texas. This hill was formed by a giant underground dome of salt as it moved slowly towards the surface. As it crept, it pushed the earth that was in its path higher and higher.

"The modern oil industry was born on a hill in southeastern Texas. This hill was formed by a giant underground dome of salt as it moved slowly towards the surface. As it crept, it pushed the earth that was in its path higher and higher. This dome was known by several names, but the one that stuck was 'Spindletop'. Through the later half of the 19th century, Pennsylvania had been the most oil-productive state in the country. All that changed on January 10th, 1901.

"Ethanol-fueled vehicles date back to the 1880s when Henry Ford designed a car that ran solely on ethanol. He later built the first flex fuel vehicle: a 1908 Model T designed to operate on either ethanol or gasoline."
-
Marcellus and Joe Jacobs develop the first commercially available wind turbine for electricity generation. The brothers knew that many remote farms were unable to electrify without using gasoline generators. Gasoline generators were too costly and inconvenient for many remote farms since gasoline had to be constantly transported in bulk over large distances. As a result, many farms remained unelectrified.

"The use of atomic bombs against the Japanese cities of Hiroshima and Nagasaki in August 1945 ushered in a new historical epoch, breathlessly labeled in countless news reports, magazine articles, films, and radio broadcasts as the 'Atomic Age.' Within a short time after the end of World War II, politicians were suggesting that peaceful applications of nuclear power could be as dramatic in their benefits as nuclear weapons were awesome in their destructive power.

"The first geothermal power plants in the U.S. were built in 1962 at The Geysers dry steam field, in northern California. It is still the largest producing geothermal field in the world."

"As the largest concentrating solar power (CSP) plant in the world, Ivanpah harnesses the abundant sunlight of the Southwest United States to provide power on a massive scale. The facility has the capacity to generate 392 megawatts (MW) of clean electricity - enough to power 94,400 average American homes. Most of the power generated by the system will be sold under long-term power purchase agreements to Pacific Gas & Electric and Southern California Edison Company.
