This has been the general direction of change in employment patterns in recent years across most sectors, although in Europe there is some indication of polarisation of demand, with growth in less-skilled jobs, but fewer jobs requiring middle-ranking skills (Cedefop, 2010b). Green technical change is no different. The more investments are made in new technologies - many of which are likely to be energy saving or related to new forms of energy generation - the more demand there will be for people in higher skilled jobs.
