How much does 150 watts cost per day?

Power is measures in watt-hours, so 150 watts for 24 hours (one day) would be 3.6 kWh (kilowatt-hours). If your electric rate is, for example, 10 cents per kWh, it would cost you 36 cents per day. In reality, many electric bills have a minimum charge, and include other charges for the service of generating, transmitting and delivering the power, plus taxes. So, for example, running a 150-watt lightbulb for a month should cost $10.80 for a month, but may actually be billed as $17, if there is no other device being used, because of the fixed costs in addition to the variable cost.
