Coal (fuel source)

As of my last update in October 2023, the cost of a ton of coal in New York can vary significantly based on market conditions, type of coal, and supply chain factors. Prices typically range from $100 to $200 per ton, but they can fluctuate due to demand, regulatory changes, and transportation costs. For the most accurate and current pricing, it's best to consult local suppliers or market reports.

Coal mines are typically cool due to their underground location, where temperatures can be significantly lower than surface temperatures. However, the actual temperature can vary depending on the depth of the mine, ventilation, and the time of year. Miners often wear layers to stay warm, but conditions can also become humid and damp, making it feel colder. Overall, while it may not be freezing, it is generally cooler than above ground.

To produce one gigawatt (GW) of electricity continuously over a 24-hour period, you would need approximately 12,000 tons of coal. This estimate assumes an average coal-fired power plant efficiency of about 33%, which is typical for many modern plants. The exact amount can vary based on the specific type of coal used and the efficiency of the power plant.

Coal mining was crucial to the industrial era as it provided the primary energy source for steam engines, which powered factories, trains, and ships. The availability of coal fueled rapid industrialization, enabling mass production and transportation of goods. Additionally, coal mining created numerous jobs and contributed to the growth of urban centers, significantly transforming economies and societies during that period. Its role in energy production laid the foundation for modern industrial practices and economic expansion.

In Birmingham, Alabama, you can purchase coal from local hardware stores, garden supply stores, and specialized fuel suppliers. Retailers like Home Depot or Lowes may carry coal or can direct you to local distributors. Additionally, companies that specialize in heating supplies or outdoor cooking equipment may also offer coal products. It's advisable to check online or call ahead for availability.

The phobia of coal is known as "anthophobia." This term, however, is not widely recognized, as phobias related to specific substances like coal are not commonly classified. Anthophobia more generally refers to a fear of flowers, but the fear of coal itself may not have a specific name in psychological literature. If someone has an intense fear of coal, it may be considered a specific phobia without a widely accepted term.

Conserving fossil fuels like natural gas, coal, and oil is crucial for several reasons. Firstly, these resources are finite and non-renewable, meaning their depletion could lead to energy shortages and increased costs. Secondly, burning fossil fuels contributes significantly to greenhouse gas emissions, which drive climate change and environmental degradation. Finally, conserving these fuels encourages the transition to renewable energy sources, promoting sustainable practices for future generations.

The cost of one ton of coal can vary significantly based on factors such as location, type of coal (e.g., bituminous, sub-bituminous, lignite), and market conditions. As of late 2023, prices generally range from $50 to $200 per ton, but they can fluctuate due to supply chain issues, demand, and regulatory changes. For the most accurate pricing, it's best to check local suppliers or market reports.

Coal is classified as a fossil fuel, which is a category of energy resources formed from the remains of ancient plants and animals over millions of years. It is primarily composed of carbon, along with various other elements, and is used mainly for electricity generation and industrial processes. As a non-renewable resource, coal is often associated with significant environmental impacts, including greenhouse gas emissions.

The coal deposits of the eastern United States began to form during the Carboniferous Period, approximately 300 to 350 million years ago. During this time, the region was characterized by warm, swampy environments with lush vegetation, primarily consisting of ferns and giant tree-like plants. These conditions facilitated the accumulation of organic material, which, over millions of years of heat and pressure, transformed into coal. The climate was generally humid and tropical, conducive to the growth of extensive coal-forming forests.

Coal was a crucial driver of the Industrial Revolution in Britain, providing the primary energy source for steam engines, factories, and transportation systems like railways and ships. Its abundant availability facilitated rapid industrialization, leading to significant economic growth and urbanization as cities expanded to accommodate factories and workers. Additionally, coal mining became a major industry, creating jobs but also leading to challenging working conditions and environmental degradation. Overall, coal transformed Britain’s economy and society, marking a pivotal shift towards modern industrial practices.

Technology has significantly improved safety and efficiency in coal mining through advancements like automation, remote monitoring, and improved ventilation systems. Automated machinery reduces the risk of accidents by limiting human exposure to hazardous conditions. Additionally, real-time data analytics help optimize mining operations, predicting equipment failures and enhancing resource management. These innovations not only increase productivity but also minimize environmental impacts associated with coal extraction.

There is an industrial process , known as SASOL, where coal is converted into (crude) oil.

This process was used in South Africa, during a trade embargo on importation of oil, due to Aparthied.

South Africa does not have crude oil as a natural resource. However, it does have plenty of coal that can be mined.

Plants are the primary source of coal formation. Millions of years ago, large amounts of plant material, such as ferns and trees, accumulated in swampy environments and underwent a process called coalification, where heat and pressure transformed the organic matter into coal. This process took place over millions of years, resulting in the rich deposits of coal we mine today. Thus, coal is essentially ancient plant matter that has been preserved and altered over geological time.

Coal liquefaction offers advantages such as providing a liquid fuel alternative to crude oil, which can enhance energy security and diversify fuel sources. It can also utilize abundant coal reserves, potentially reducing dependency on imported oil. However, disadvantages include high costs, significant greenhouse gas emissions, and environmental concerns related to mining and water usage. Additionally, the technology is energy-intensive and may not be economically viable without supportive policies or high oil prices.

Cities with factories powered by coal experienced significant industrial growth during the 19th and early 20th centuries, leading to economic prosperity and urbanization. However, as awareness of environmental issues and health risks associated with coal pollution increased, many cities faced challenges such as declining air quality and public health crises. In recent decades, many have transitioned to cleaner energy sources, resulting in the closure or conversion of coal-powered factories. This shift has sometimes led to economic decline in regions dependent on coal, but also opportunities for innovation and sustainable development.

The amount of coal used each year varies significantly depending on factors such as location, energy needs, and available resources. In the United States, coal consumption has declined in recent years due to a shift towards cleaner energy sources. As of 2021, the U.S. consumed about 535 million short tons of coal, primarily for electricity generation and industrial processes. Individual usage can vary widely, so it's best to check specific local or national statistics for precise figures.

The NTPC Dadri power plant, located in Uttar Pradesh, India, consumes approximately 25,000 to 30,000 tons of coal per day, depending on its operational capacity and demand. This plant, which has a total installed capacity of 1,550 MW, primarily utilizes coal to generate electricity. The specific amount of coal used can vary based on factors like power demand and generation efficiency.

Ferns, along with other plant material, contribute to coal formation through a process called coalification. After ferns die, they accumulate in swampy environments, where they are buried by sediment. Over millions of years, heat and pressure transform this organic material into peat, and eventually into coal through a series of chemical and physical changes. This process can take millions of years, resulting in the carbon-rich deposits we mine today.

It produces new substances like carbon dioxide (CO₂), water vapor (H₂O), sulfur dioxide (SO₂), and ash.

The process is irreversible — coal cannot be recovered after burning.

It involves a chemical reaction (typically with oxygen), releasing heat and light (exothermic reaction).

Thirty-eight years after coal burning was banned, the moth population likely shows signs of recovery due to improved air quality and reduced environmental pollutants. With healthier ecosystems, habitats for moths would be less degraded, supporting their resurgence. However, the overall impact would also depend on other factors such as climate change, habitat loss, and pesticide use, which could still pose challenges. Therefore, while there may be an increase in moth numbers, the extent of recovery could vary regionally.

Coal mining in the U.S. raises several ethical issues, including environmental degradation, health risks to local communities, and the displacement of residents. The process contributes to air and water pollution, leading to respiratory problems and contamination of drinking water sources. Additionally, the industry's reliance on fossil fuels conflicts with global efforts to combat climate change, raising concerns about the long-term sustainability of energy practices. Finally, the economic dependence on coal mining can hinder the transition to cleaner energy sources and undermine workers' rights and safety.

Heating coal leaves the solid 'coke' , which is impure carbon , and used in blast furnaces for iron ore reduction to iron.

Heating petrol will create a vapour which may spontaneously ignite. The solid left behind is carbon (soot).

The oldest coal mines in the United States are primarily located in Pennsylvania, with the Anthracite coal region being particularly significant. Coal mining in this area dates back to the late 18th century, around the 1760s. Other early coal mining areas include parts of Virginia and West Virginia, which also have a rich history of coal extraction.

Coal dust is not considered a mineral.

Here’s why:

Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystalline structure.

Coal, on the other hand, is an organic material formed from the remains of ancient plants. It does not have a consistent chemical formula or crystalline structure, so it doesn't meet the strict definition of a mineral.

Coal dust is just fine particles of coal — so it's still organic, and still not a mineral.

However, coal dust can contain trace amounts of minerals, especially if mixed with other rock or impurities from the mining process. But as a whole, it’s not classified as a mineral.
