What is a kilowatt hour? Understanding home energy use

Utilities bill for electricity in kilowatt hours (kWh), but what does that mean exactly? And what is the difference between a kilowatt and a kilowatt hour? Knowing the difference helps you understand the impact of your home energy use on your electric bill. You can also compare your use to the energy generated with your Enphase system to appreciate the energy savings on your utility bill.

    power= energy/time

    You don’t ‘consume’ power! You consume energy.

    Why would you exclude weekends for an easier example. Some people work on weekends, you know?

    Enphase explains all of these concepts better than the school I paid for.
    I believe the schooling is trying to be confusing on purpose because enphase makes it click real easily for me. Thanks enphase, we will continue to use your products. We love you’re micro inverters

    Ms.boltons class??? Anyone??

  24. Matthew Dixon on December 2, 2021 at 6:14 pm

    So with he analogy they had d=rt or miles=mph(time). So if you go at 50mph down the road in 1 hour you are expected to have gone 50 miles. If that is the case energy=power(time) or e=pt that would make it that kWh=kilowatt(x hours). So if your home used say 1000kWh and you would want to find how many kilowatts were used in 1 hour it would be: 1hour (1000kWh)=x kilowatts. The hours then cancel leaving you with only kilowatts? This would make the usage of 1000 kilowatts in 1 hour?
