Hi was thinking about maybe starting to mine altcoins the only problem is would you say 0.07 USD per KHw is to expensive?
Are you sure that $ 0.07 is your total electricity cost or is it your shopping price? Where I live electricity is advertised @ $ 0.079 per kilowatt but that does not include distribution, transmission and other charges. So while it is listed @ $0.079 it is more around $0.14. That's almost double the quoted price. Just look at your power bill real close and deconstruct it with math. Otherwise you are going to be setting yourself up for a disappointment.
Sounds like Alliant Energy, where the "extra fees and taxes" were often a majority of my total bill.
Nice thing about the 3 counties of Central Washington "Super Cheap Power Rate", the rates are very simple the only "extra fees" not spelled out in the BASIC RATE SCHEDUAL are the local/state sales tax, and the ALL UP price for 2 of the 3 counties for ALL service types comes to around 3 cents/kwh OR LESS (the third has 4.5 ballpark all-up cost for residential and small business).
Solar is MORE expensive when you factor all the costs in, unless you get some HUGE government rebates on the equipment costs - and you have to tie into the electrical grid ANYWAY for when the array isn't producing full output or close, or you have to have HUGE battery banks which tend to increase your investment cost a lot AND the batteries wear out and need replacement over time.
Wind - is similar, but is closer to being competative with normal power generation in many areas and in some high-price electric areas like in California that also have fairly high average winds (Tehachapi Pass or the Cajun Pass areas as examples) it might BE the low-cost option.
