What is the annual use of coal for energy in the United States measured in quadrillion BTUs?

The annual use of coal for energy in the United States is approximately 18 quadrillion BTUs. This measurement reflects the significant role that coal has historically played in the energy landscape, particularly in electricity generation. While natural gas and renewable sources have been gaining prominence in recent years, coal still contributes a notable percentage to the overall energy mix.

The figure of 18 quadrillion BTUs is derived from energy consumption data, which shows that coal remains a critical source of energy, particularly for power plants that rely on it for electricity generation. Although usage has declined compared to previous decades due to various factors including environmental concerns and the rise of alternative energy sources, it still stands as a substantial number in the context of the nation's overall energy consumption.

Understanding these statistics helps illustrate the shifts in energy consumption patterns and the ongoing transition towards cleaner energy sources while acknowledging the historical importance of coal in the U.S. energy sector.
