Conversion KWH of energy per day to Joules in a year

Click For Summary
SUMMARY

The discussion focuses on converting energy consumption from kilowatt-hours (kWh) to joules for an appliance that uses 6.65 kWh per day. The average power consumption is calculated as 277 watts, derived from dividing 6650 watts by 24 hours. To find the annual energy consumption in joules, the formula P = W/t is applied, where P is power, W is energy output, and t is time in years.

PREREQUISITES
  • Understanding of energy units: kilowatt-hours (kWh) and joules (J)
  • Basic knowledge of power calculations using the formula P = W/t
  • Familiarity with time conversion from days to years
  • Ability to perform unit conversions in energy calculations
NEXT STEPS
  • Research the conversion factors between kilowatt-hours and joules
  • Learn about energy consumption calculations for different appliances
  • Explore the implications of power consumption on energy efficiency
  • Investigate the impact of appliance usage on annual energy costs
USEFUL FOR

Electrical engineers, energy analysts, and homeowners interested in understanding and optimizing energy consumption of household appliances.

What is the average power consumption in watts of an appliance that uses 6.65 kW*h of per day?

6650/24=277 W

b) How many joules of energy does this appliance consume in a year?

What is the conversion factors for b)?

P = W/t. (P = power, W = work = energy output more or less, t = time.) You've got P from part a and now t = 1 year.
