Reykjavik Energy Group produces renewable energy, electricity, and hot water, from sources such as geothermal energy and hydropower. The Group utilises about 10% of produced electricity and a little under 1% of its hot water production for its own operations.

Fossil fuels, particularly diesel oil and methane, are used during construction activities and operations by the consolidation. All fossil fuel is identified as indirect energy consumption, as it is purchased from a third party.

The proportion of direct energy consumption (electricity and hot water) by Reykjavik Energy Group is 99.9%, and indirect energy consumption (fossil fuels and methane) is 0.1%.
