How would the cost of operating a 30 watt bulb relate to the cost of operating a 60 watt bulb for a given amount of time?
never [62]
Utility companies charge based on consumption in kWh. Range of approximately 3 to 10 cents per kWh (rates vary by locale)

So consumption is directly proportional to watts of the load.

A 30 watt light bulb running for 100 hrs
would cost half of what a 60 watt bulb burning for the same time frame.

30 x 100= 3 KWh

60 x 100= 6 kWh

So use LED lights that give same lumens for much less watts of power
