Показать описание
Electricity is measured in kilowatt-hours (kWh).

One kilowatt-hour of energy is enough electricity to:
• Cook breakfast for a family of four
• [Or] Vacuum for one hour
• [Or] Watch 10 hours of TV
• [Or] Listen to the radio for 20 hours

On average, a single family home in the United States uses about 911 kWh per month, that’s almost 11 thousand kWh per year.

One hour of using your AC uses approximately 3 kWh.
One hour of using your ceiling fan only uses about 0.075 kWh.

One load of laundry washed in hot water and rinsed in warm water will use approximately 4.5 kWh per load.
One load of laundry washing in cold water and rinsed in cold water only uses about 0.3 kWh per load.

No, it's kW & kWh not KW & KWh. The 'k' is short for kilo meaning times 1000. The unit is named after James Watt (he who watched steam kettles) so the initial is capitalised. The hour is just' h'.
If you look at the suggested videos on the YouTube page you will note that many people make the similar errors
