Coal
Fossil fuels were not widely used until the Industrial Revolution due to a combination of technological, economic, and social factors. Prior to this period, most societies relied on renewable energy sources like wood, wind, and water for heating and transportation. The development of steam engines and advancements in extraction and refining techniques during the Industrial Revolution made fossil fuels, particularly coal and later oil, more accessible and efficient for powering factories, transportation, and machinery, leading to their widespread adoption. Additionally, the growing demand for energy to support industrial growth further propelled the use of fossil fuels.
Roughly 85% of the world's energy comes from fossil fuels, with billions of people relying on them for transportation, heating, electricity, and industrial processes. This makes fossil fuels currently the most widely used source of energy globally.
The world's most abundant fossil fuel is coal. Coal is a solid fossil fuel formed from plant material that has been subjected to high pressure and heat over millions of years. It is widely used for electricity generation and industrial processes.
It would likely be oil, as it is the most versatile and widely used fossil fuel. Oil is essential for transportation, heating, electricity generation, and various industrial processes. Finding alternative sources for all these applications would be the most challenging compared to other fossil fuels.
Coal is the most widely used fossil fuel because it is relatively abundant, inexpensive, and has a high energy content. It is also easy to transport and store, making it a convenient option for power generation and industrial processes. Additionally, coal reserves are distributed worldwide, further contributing to its widespread use.

The Industrial Era, often marked by significant technological advancements and changes in manufacturing processes, generally spans from the late 18th century to the mid-19th century. It began around the 1760s with the onset of the Industrial Revolution in Britain and continued until approximately the 1840s or 1850s, when industrialization began to spread more widely across Europe and North America. Some historians extend the timeline into the early 20th century, considering ongoing industrial developments during that period.
Monopolized smaller businesses and then used their power to inflate prices on their goods that were now widely available to others. Led to construction of railroads and large cities of steel.

The spinning jenny was invented by James Hargreaves in 1764 and began to be used in textile production shortly thereafter. It gained popularity in the late 18th century during the Industrial Revolution, significantly enhancing the efficiency of yarn production. By the 1770s, it was widely adopted in England's cotton industry.
The hammer and sickle symbol originated during the Russian Revolution of 1917, representing the alliance between industrial workers and agrarian peasants. The hammer symbolizes industrial labor, while the sickle represents agricultural labor. It was adopted by the Soviet Union as a representation of communism and socialism, signifying the unity of the working class. The emblem became widely recognized as a symbol of leftist movements around the world.
Ideologically for the most part. More research needs to be done about his actual contributions during his lifetime, but widely accepted timelines have him as an old man when during the war.
