It's not the power that is the problem with the gridseed, they got that sorted out, its the price.


Instead of the power company juicing you, you get to pay up front to gridseed (AMD:180/450=40 cents a Kh, vs gridseed .$1 or 60cents, if buy in bulk like the user above).


The thing about paying for power, is that you get to keep your power in bitcoins.  Hence, if my power usage of running my cards is 25%, that does not disappear, its stored in my bitcoins.  Rather then me buying bitcoins at the exchange, I buy power from the power company and make my own currency.   So in the future, I can salvage my power bill because ALL power used is sitting in my bitcoin.

 

The above example, starts to diminish with gridseed, but because of the steep up front costs, thats not going to happen for a long long time.


Also, those of us who have invested in renewable energy, are not selling it back to the grid at the bulk rate, we sell it at the going rate and get it in bitcoin. (think about that)


Believe it or not the technology to lower your power costs was out before bitcoin/gridseed, both of these strategies have to be employed by those mining for truly effective returns.  Get solar panels, get wind turbines, let your mining pay those technologies off.
