The answer depends on many factors (climate, seasonal weather variations, home size, the # of occupants in the home, personal comfort preferences (temp, humidity, air freshness), the amount & intensity of sunlight & wind that hit the home, the amount of shade from trees or other objects that reduce sunlight exposure, the the quality of insulation used in the home construction, the air-tightness of the home, etc.)
More energy will be used in a modern home in the upper mid-west (e.g. Chicago, IL) than the exact designed home which is built in a milder climate (e.g. San Francisco, CA).
In Houston, TX (which is a hot & humid climate for at least 6 months of the year) my annual electric cost is approximately: 1,000 $/yr (i.e. an average of: ~9125 kWh/yr or ~760 kWh/month or ~25 kWh/day). Maximum/minimum monthly electrical usage is of course much higher/lower, depending on how hot/mild the conditions are outside.
15 watts
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
It depends on the amount of amps... you have to multiply the voltage (V) with the ampere (I) to get the power (P) in watts.
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
18650 watts
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts (Doesn't matter if the source is AC, DC, or a combination of both.)
To find the time taken to perform 500 joules of work at a power of 25 watts, you divide the work by the power. In this case, 500 Joules / 25 watts = 20 seconds. Therefore, it would take 20 seconds to perform 500 Joules of work with 25 watts of power.
you couldnt, you'd need 1.21 jigga watts to send you back to the future
If the average home consumes 43 kilowatts per day that equals 43,000 watts per day, the average solar panel produces 85 watts per hour so if u multiply that by the average number of hours it will be working and it equals just over a kilowatt per day. So to power the average home you would need around 40-45: 85 watt panels.
2050 watts
Lights range from 300 to 1000 watts and there can be hundreds of them. Amps are rated by watts and they are useing many of these at a time. A concert probably uses more power than a very large house does in a year.
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
