Ground-source heat pumps and underground thermal energy storage: energy for the future [PDF]

open access: yes, 2008
We need energy for space heating—but in most cases not where or when energy sources are available. Energy storage, which helps match energy supply and demand, has been practised for centuries, also in Norway.
