How do you calculate the cost of electrical energy consumed?
How do you calculate the cost of electrical energy consumed?
Let’s do the math by hand:
- power consumption * usage time = power consumed . So we’ll consume 10000 watt hours or 10 kilowatt hours of power every day.
- The electricity cost is cost = power consumed * energy price .
- For the annual cost, simply multiply the daily one * the number of days in a year.
