How do I calculate power consumption NZ?
Energy use for 365 hours = annual energy consumption (kWh, based on 10 active hours a day) / 10 (active hours a day) Annual running cost = energy use for 365 hours x electricity cost ($/kWh) x running hours per day.
How do I calculate how much power my house uses?
How to Calculate Power Consumption in kWh?
- Daily Power Consumption. Daily Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs = 6000 Watts-Hour.
- Monthly Power Consumption. Monthly Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs x 30 days = 180000 Watts-Hour.
- Annual Power Consumption.
How much kWh does a house use NZ?
A house on average uses about 7,000 kWh of electricity, but the amount used depends where in New Zealand you’re living and how your house and hot water are heated. In 2017 average residential consumption varied from about 5,870 kWh on the West Coast to 8,550 kWh in Canterbury.
How do I calculate my electric meter reading?
Calculate Your Electricity Bill in 1 min by Simple Calculation. Electric Energy Bill Calculator
- Example:
- Total Consumed Units = 720.
- E = P x t … ( Wh)
- E = P x t ÷ 1000 … ( kWh)
- Consumed Energy = Energy Used in Watts x Time in Hours.
- E = P x t … ( Wh)
- E = P x t ÷ 1000 … (
- Energy Cost = Energy Used in kWh x Time in Hours.
How do you calculate power consumption per hour?
The “kilowatt-hours” you see on your power bill expresses the amount of power that you consumed in a month. To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000.
How many kWh per day is normal NZ?
As a very rough estimate a typical NZ home with 2 adults and 2 children would consume between 15 and 28 kWh per day.

How do you calculate electricity usage per year?
The above power calculator uses a simple formula to calculate annual energy usage and costs. Here’s how it works: Electricity Usage Per Year = (Watts / 1000) * Hours/Day * Days/Week * Weeks/Year = kWh/year
How to calculate the daily energy usage of a fan?
Daily Energy Consumption. Power Consumption (Daily) = Power Usage (Watts) x Time (Hours) Example: An 80 watts fan used for 4 hours daily. The daily watt hour and kilowatt hour consumption is as follows. Daily power usage in Wh = 80W x 4 Hours = 320 Wh / day; Daily power usage in kWh = 320 Wh /1000 = 0.32 kWh / day; Monthly Energy Consumption
How to calculate the annual energy consumption of a kettle?
Annual Energy Consumption Power Consumption (Annual) = Power Usage (Watts) x Time (Hours) x 365 (Days) Example: A 1700 Watts Electric kettle runs for 1 hours daily. Calculate the energy consumption in Wh and kWh in one year.
