Direct Use of Geothermal Resources
Iceland is well known to be a world leader in the use of geothermal district heating. After the second World War, Orkustofnun carried out research and development, which has led to the use of geothermal resources for heating of households. Today, about 9/10 households are heated with geothermal energy.
Space heating is the largest component in the direct use of geothermal energy in Iceland. The figure here on the right gives a breakdown of the utilization of geothermal energy for 2011. In the year 2011, the total use of geothermal energy was 42,2 PJ, with space heating accounting for 45%.
