The geothermal energy resources in Oman are being considered through studying the temperature data from Petroleum Development Oman (PDO). The review of geothermal energy shows that the cost of electricity generation and the emission of greenhouses gases are comparatively lower than for other forms of renewable energy resources. Different types of geothermal plants are discussed with reference to the required temperature for operation of these plants. Binary cycle geothermal power plants are used for low-temperature applications (85�C-175�C). The temperature of 53 boreholes in Oman is more than 100�C, indicating that they can be used in binary geothermal plants for electricity generation. The maximum temperature (173.68�C) is at PDO well "Makarem-I" located in the northern part of Oman. There is opportunity for Oman to adopt renewable energy resources and explore the potential of geothermal in more detail, reducing its dependency on oil and gas and compete in the region towards adopting renewable energy.
