As an expert in the field of energy resources, I can provide you with a detailed analysis of the costs associated with purchasing coal. The price of coal can vary significantly based on several factors, including the type of coal, its quality, the location of the mine, and the current market conditions.

To begin with, the type of coal is a critical factor in determining its price. There are different types of coal such as anthracite, bituminous, sub-bituminous, and lignite. Anthracite is the highest quality coal and is typically more expensive, while lignite is of lower quality and less expensive. Bituminous and sub-bituminous coals fall in between in terms of quality and price.

The quality of the coal is another important consideration. Coal with a higher energy content (measured in British Thermal Units or BTUs) will generally command a higher price. Additionally, the sulfur content of the coal can also affect its price, as coal with lower sulfur content is preferred for environmental reasons.

Geographical location plays a significant role in the cost of coal. The cost of mining coal can vary depending on the accessibility of the mine, the local labor costs, and the regulations in place. Furthermore, the transportation costs from the mine to the point of use can also add to the overall price of coal. As mentioned in the reference provided, in 2015, the average transportation cost accounted for about 25% of the total delivered price.

Market conditions and global economic factors can also influence the price of coal. Supply and demand dynamics, as well as geopolitical events, can cause fluctuations in coal prices. For example, if there is a surge in demand for coal due to increased industrial activity or a cold winter, the price may rise. Conversely, if there is an oversupply or a shift towards renewable energy sources, the price may decrease.

Additionally, government policies and environmental regulations can have a significant impact on coal prices. Policies that encourage the use of cleaner energy sources or impose stricter emissions standards can reduce the demand for coal, potentially lowering its price. On the other hand, policies that support the coal industry can help maintain or increase its price.

It's also worth noting that the price of coal can be affected by the method of sale. Some coal is sold under long-term contracts, which can provide price stability but may not reflect the current market price. Other coal is sold on the spot market, where prices can be more volatile.

In conclusion, the cost of purchasing coal is influenced by a complex interplay of factors including the type and quality of coal, geographical location, transportation costs, market conditions, and government policies. While the reference data from 2015 provides a snapshot of historical prices, it's essential to consider the current context and the specific details of the coal purchase in question to determine the actual cost.
