A lot of small miners are beginning to get those electric bills. For some places it is absolutely not profitable to mine in a PPLNS pool (which is most pools out there) A lot of people can not wait 60 to 80 hours for a payout that pays for only 30% of the shares they put in. They can not even cover the electric with those kinds of payouts.
With this happening the late comers are either shutting their machines off completely or wisening up and switching to a coin they can solomine and dump with a higher profit margin until the BTC price goes back up and becomes more profitable.
It may go down again as some countries are enetering their summer months when the electric companies hike the electricity costs even more. (like where I am GRRRR)
Soon the only profitable way to mine in small farms will be to already have a solar system in place to cover your electricity costs. And like where I am also make your electricity much more stable.
We are looking into solar for our farm now
