In ny its 10-16 cents per kilowatt hour. If i ran 150 watts for 24 hours a day, what would the sum be after a month..... Whats confusing me is the kilowatt hour, is that just a normal hour?
1kWh = 1000 watts per hr. So, a 150wat system uses 0.150 kWh of electricity every hour. Times 16c maximum, is 2.4c/hr of usage. So, per month, you're looking at $17.28 per month.
