Your basal metabolic rate approximates 100 watts. Thus 1000 watt-hours equals about 10 hours of your existence.
A watt is a unit of power. 1 watt = 1 joule/second; that is, if somebody consumes 1 watt, it consumes 1 joule of energy every second. Or if there is a transfer of 1 watt, 1 joule of energy is transferred every second. 1000 watts (1 kW), of course, is simply 1000 times as much (1000 joule/second).
It is equal to 4.5 joules per second. "Watt" means how quickly energy is generated, consumed, or converted.
1 kilowatt = 1,000 watts1 watt = 1 joule per second1 hour = 3,600 seconds(1,500 kilowatt-hour) x (1,000 watt / kilowatt) x (1 joule / watt-second) x (3,600 second / hour) =(1,500 x 1,000 x 3,600) x (kilowatt - hour - watt - joule- second) / (kilowatt - watt - second - hour)= 5,400,000,000 joules
The simple way to calculate cost is $1 per watt per year. This is based on a cost of about 11 cents per kilowatt hour. Your cost may vary. So, 60 watts times 1/2 year (12 hours /day) divided by 12 ( 1 month) equals $2.50 per month.
