Look at how much energy our solar panels have produced:
In 2016 we produced over 9500 kilwatt hour (kWh) and in 2017 over 8500 kWh.
So what exactly is a kilowatt hour?
A kilowatt hour (kWh) is a measure of how much energy you’re using.
It doesn’t mean the number of kilowatts you’re using per hour. It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour.
So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy.
What else takes around 1 kilowatt hour?
Here are some rough examples of 1 kWh:
- Using a 10,000 watt electric shower for six minutes
- Keeping an immersion heater (3,000 watts) on for 20 minutes
- Cooking in a 2,000 watt oven for half an hour
- An hour’s ironing with a 1,000 watt iron or 45 minutes with a 1,500 watt iron
- Less than an hour using a dishwasher (1,000 - 1,500 watts)
- Around three hours watching a plasma TV (280 - 450 watts)
- Keeping a fridge-freezer (200 - 400 watts) on for about three hours
- Keeping an electric blanket (130 - 200 watts) on all night
- Using a laptop (20 - 50 watts) all day
- Keeping a broadband router (7 - 10 watts) on for five days
