Knowing that it is necessary a great demand of electric energy to mining Bitcoins and knowing that much of the energy matrix arising from the exploitation of non-renewable resources and ask a question at all.
Do you think the Bitcoin is sustainable?If you are a miner, what is the cost in dollars into electrical energy is required in your region (mark your country and region) to generate 1BTC?

It depends really on location. Somewhere where there is vat/high import tax. It's going to be hard to start. Then if high electricity no way this location could mine without loss.
Cheap electricity with no import tax/vat you can ROI. Many big data centers have chased this low priced electricity.
Overall i think it is sustainable, it is going to take the price of BTC to change as time goes on though.
