yes indeed, gas is getting extremely expensiv. We have central heating with gas, and it is costing us an arm and a leg. Wish we had been better informed.... Çok geç (Turkish for: too little, too late)
But I'm not here to complain. The reason I react is the following: apparently it is (or soon will be) illegal to burn coal! Has to do with climate preservation rules that already apply for western-Europe and are already (or will be soon) applicable in Turkey as well....(are they really going to join? First smoking, now this, what is next: the very strict insulation rules (in order to prevent spilling of energy) that apply in the EC???, we shall see...soon enough, and then probably will be fined if our houses are not insulated enough - as is happening in the EC)
Not sure yet where you would find more info on this ruling...
