What percentage of the world's coal reserves is held by the U.S.?

The correct answer indicates that the United States holds approximately 25% of the world's coal reserves. This significant figure reflects the vast coal deposits found primarily in regions like the Appalachian Mountains, the Illinois Basin, and the Powder River Basin.

The reason this percentage is notable is due to the U.S. having one of the largest coal reserves globally, which influences the country’s energy policies and energy independence. Understanding the percentage of reserves helps in discussions about energy sustainability, climate change impacts, and the transition to renewable resources. The fact that a relatively small number of countries collectively hold the majority of coal reserves highlights the geopolitical implications, as reliance on coal can affect global markets and climate agreements.

In context, while countries like China and India have rapidly increased their coal consumption, the established coal reserves in the U.S. position it as a key player in discussions about energy production and environmental policy globally.
