“…Barriers can be mitigated by governments by well‐targeted energy efficiency policies, programs, and well‐designed instruments (Liu et al, 2019), to remove the energy efficiency gap and realize energy efficiency potentials (Grubb, McDowall, & Drummond, 2017; Jacobsson, Bergek, & Sandén, 2017; Kern, Kivimaa, & Martiskainen, 2017; Purkus, Gawel, & Thrän, 2017; Rosenow et al, 2016; Rosenow et al, 2017). However, as stressed by Wohlfarth, Eichhammer, Schlomann, and Mielicke (2017) and Safarzadeh et al (2020) usually information deficits (imperfect information) are the most relevant challenges in industrial sectors, and this may require implementation of instruments to promote internal knowledge capacity‐building, information gathering, and technical capacity‐building.…”
