Iceland has been an international leader in geothermal energy for the past century and is now a major exporter of the technology. This presentation is on the types of geothermal systems used in Iceland, the strategies for utilising geothermal energy for heating and electricity production, and the environmental and economic benefits of geothermal energy. Furthermore, the challenges that have been faced in the development of geothermal energy in Iceland and the solutions that have been implemented to overcome them will be discussed. Finally, the potential for the development of geothermal energy in India and the transfer of knowledge from Iceland to facilitate this will be discussed.
