Perché le città di Cipro non sono così?

I think there is not enough economic pressure to force gov’t and public to rapidly switch to solar. The oil it still there, the oil infrastructure is still there, and it still works. At least I’m happy I have a solar heater on my roof, so the water is hot whenever the sun is shining.

Cyprus is actually a world leader in the amount of solar thermal installations, so many of the rooftops already contain measures to harness the sun’s energy.

In addition as you mentioned Cyprus being a small island which is disconnected from any other grid makes it incredibly difficult to manage large amounts of energy suddenly flowing back into the grid. Electricity networks are just not designed for that, and with nowhere to dump the energy it could damage the infrastructure.

All new buildings in Cyprus do in fact mandate some PVs but if course it hasn’t been applied retroactively.
