kW / kWh: What’s the Difference? Power & Energy Explained
36,327
Published 2023-01-08
** Before you comment, I have to hold my hands up - I overestimated the power of a plugged-in clothes dryer - in the UK this can only ever be up to 3kW because of the 13 amp fuse in the plug! Apologies for that **
Chapters:
0:00 Intro
0:40 Power and Energy
2:41 Kettle
4:46 Lightbulb
6:17 Typical appliances
6:42 Power measurement
10:39 Solar installations
15:15 Summary
Corrections:
6:27 In the UK, a clothes dryer on a standard 13 amp plug will operate at a maximum of 3kW
7:18 The example value here is impossible - In the UK, a standard 13 amp plug can only provide up to 3kW
If you're getting a lot from my videos, and would like to support me in my efforts to help everyone, here are a couple of ways to do this:
1. You could www.buymeacoffee.com/GaryDoesSolar :-)
2. If you're thinking of switching energy supplier to Octopus Energy. If you call them and give them my referral code ("blue-wind-201") and my name ("Gary Waite") and we'll both get a £50 credit to our accounts as a result! share.octopus.energy/blue-wind-201
I believe Octopus Energy is doing more than any other energy company in the UK to take us forward to a bright renewable future, and I'll make making reference to them and their initiatives in future videos.

One thing we did years ago to reduce energy usage was to buy a HotCup with Variable Dispense which means we only boil one cup of water at a time, which is a lot faster and thus uses a lot less KwH.

Thanks for your videos Gary, they are quite simple and direct. Viewed this video from Nigeria in West Africa. Just an observation here, Your conversion of 4 minutes to hours should be 4 minutes divided by 60 minutes and not 60 minutes divided by 4 minutes as you mentioned in the video. 60 minutes divided by 4 minutes gives 15 minutes. 4 minutes is a fraction of an hour and not a whole number or an integer. You got the conversion right but said it the wrong way which in my thoughts might get some people confused.

Good info in plain English.👍
-
Very good explanation.
-
Wonderful videos. Simple and easy to understand (South Africa)

What a great video Gary and thank you for taking the time to make it. This is something the government should do to give people advice on how to save money on their electric bill now we are in a cost of living crisis. 👍
-
Excellent video … thank you!
-
Excellent explanation. Thanks
-
Great video Gary, another option for folk to measure appliances is to use a energy monitoring smart plug which can be got quite cheaply these days and give the additional benefit of being able to put the appliance on a time schedule.

Scary drop at 15:23 - great work Gary!
-
Really excellent video, thanks for taking the time to do this.

Hi Gary, I love your videos, very useful for someone who's new in the solar industry. I just wish there'd be more ;)
-
Excellently explained, thank you
-
Another excellent video.I wish 40 years ago my physics teacher had explained power and energy this way. Back then it was about moving objects like you showed with the box. It is much easier to understand when someone explains it with day to day examples. Top job.
-
Thanks for un-muddying the waters! Just used your code-thanks
-
These videos you made are extremely informative and helped me understand the entire cycle much better 🎉 thank you 🙏
-
Gary, you need to get into solar sales! You know it all and there is crazy money to be made working on sales.
-
great video thank you
-
Excellent video, very helpful !

Excellent videos Gary. I have had my 4kW system with battery storage since July. Your videos would have definitely helped me and if anyone needs help with installation, I point them to your channel. Hope your install goes well once installed it starts taking over your day making subtle changes to your routines ensuring that high consuming devices are not on together. Keep up the good work.
