They don't even pay for electricity they get from rest of Serbia. And Serbia has to give, otherwise they shut down power grid in northern Kosovo, where most of the Serbs are.
Hmm...that could be one reason why Serbs haven't been totally cleansed from Kosovo: blackmail. If those Serbs in northern Kosovo were cleansed, Serbia could cut off all the electricity without concerns about Kosovo Serbs being deprived. Further, Serbia could then mine all the border with Kosovo and seal it off - it would hurt Kosovo much more than Serbia.
The power supply source is in the hands of the Albanians. While in Leposavic, the Albs would turn off the power and turn it back on. Excuse was- power surge, too much "usage".
