Based on the proved coal reserves data for Indian states, the correct sequence in decreasing order is Odisha, Chhattisgarh, West Bengal, and Jharkhand.
– Odisha holds the largest share of proved coal reserves in India, followed by Chhattisgarh.
– While Jharkhand has the largest share of *total* coal reserves (including proved, indicated, and inferred), its share of *proved* reserves is typically lower than Odisha and Chhattisgarh and often falls below West Bengal as well depending on the data source and year.
India has significant coal reserves. The distribution across states is a key aspect of its energy geography. Coal reserve data is periodically updated by agencies like the Geological Survey of India (GSI) and the Ministry of Coal. The terms proved, indicated, and inferred refer to the degree of geological assurance of the existence and recoverability of the reserves. Proved reserves have the highest degree of certainty.
