Coal accounts for 55% of India's energy needs . The Coal resources of India are available in two formations namely Gondwana Formations and tertiary formations. Hence, Statement 1 is correct. Gondwana formation is older and is found in peninsular India. The Gondwana coal fields are located in the sedimentary rock systems of the lower Gondwana Age . Tertiary Formations are younger in age and are abundant in the North-East region which includes Assam, Meghalaya, Nagaland, Arunachal Pradesh, Jammu & Kashmir, and Sikkim. Gondwana coal fields contribute 98% and the rest 2% is produced by tertiary coal fields. Hence, Statement 2 is incorrect. Coal can be classified into Anthracite, Bituminous, Lignite, and Peat coal . Jharkhand ranks highest in production as well as reserves of coal in India. Hence, Statement 3 is correct.
