"Models of this type could replace the current energy model, which is virtually in the hands of five major companies, and make it more democratic, non-profit making, and one in which citizens can play an active role in energy, which is something so important and central to their lives," pointed out Jon Terés. > Yet "renewable energies are not enjoying the best of times; even though they have had very strong institutional support since 2004, a series of regulatory changes took place around 2011 and almost completely hampered the possibility of implementing renewables in an economically viable way, and led to the bankruptcy of enterprises and small investors," explained Campos.
