Could government legalize illegal settlement by improving their energy efficiency

In recent months we are faced with serious budget problems in Montenegro, the solution of which, among other things is seen in reducing the number of employees in state administration. On the other hand, the costs of living are significantly above the disposable budget of households. Particular problem is the high cost of electricity, which recently resulted in the street protests of discontented citizens. On one hand we have a government that alerts the lack of electricity, and on the other hand we have citizens that may hardly cover these costs. In addition, Montenegro is dealing with a double-challenge of inefficient space use (country features over 100,000 illegal homes, if distributed evenly implying that every other family lives in an illegal home) and inefficient energy use (Montenegro needs on average 8.5 times more energy per unit produced than an average EU country).
