Geothermal energy is a renewable source of energy which uses the heat available underneath the earth's surface. It is used in direct heating (district and space heating, industrial and commercial uses) and for electricity generation. Geothermal energy has the potential to contribute significantly to any country's energy portfolio. However, this market is still growing in terms of technology, transmission planning, and grid operation. Currently, three different types of technologies (power plants) are being used for the production of heat and electricity.
Electric generators are equipment that produces electrical energy through the conversion of mechanical energy, using either diesel or gas as fuel. They can be used in industries, commercial buildings, or residential buildings depending on their power capacity, and they ensure that end-users receive an uninterrupted electric power supply during power disruptions. Electric generators are classified into two major segments: Stationary and Portable generators. A stationary generator is a generator which is connected to a network, and can be either fixed or installed to get an uninterrupted power supply in case of power outages.
