Reserve Estimate - an overview ScienceDirect Topics

CBM is related to coal reserve. Coal remains a crucial contributor to energy supply in many countries. Coal is the most widespread fossil fuel around the world, and more than 75 countries have coal deposits. The current share of coal in global power generation is over 40% (WEO, 2013). These coal reserves are directly related to CBM.
