      Ramstad, Randi K.; Sørdal, Torbjørn; Solli, Arne; Midttømme, Kirsti; Elvebakk, Harald (NGU-Rapport (2004.013), Report, 2004)
      Geologien i området er avgjørende for om bruk av grunnvarme med energibrønn i fjell vil være et økonomisk lønnsomt alternativ. Tykke leir eller sandlag over fjell vil øke borekostnadene og berggrunnens egenskaper vil ...
