25 watts * 24 hours = 600 watt hours = 0.6 kwh

{1 kilowatt hour = 1000 watt hours}

0.6 kwh * (0.085156 per kwh ) = 0.0510936 or about 5.1 cents

To calculate the cost, you need to first convert the wattage to kilowatts by dividing 25 watts by 1000 (since 1 kilowatt = 1000 watts), which equals 0.025 kW. Next, multiply the kilowatts (0.025 kW) by the number of hours the light bulb is on (24 hours) to get 0.6 kWh. Finally, multiply this by the cost per kWh (\$0.085156) to get the total cost, which is approximately \$0.0511.
