• Developed – resources that are surveyed and their quality and quantity have been determined for utilization (Petroleum, liquid gas)
• Stock – resources available but do not have the appropriate technology to access (lack of technical know-how to use hydrogen and oxygen as a source of energy)
• Reserve – can be used for future needs (water in the dams)
