Last time I check it went anywhere from 4 cents to 12 cents per kWh. Therefore 30 kWh of electricity (100 hours at 300 watts) would cost anywhere from $1.20 to $3.60How much does electricity cost?Don't grow the weed. It's illegal!How much does electricity cost?Not sure this one corresponds to, it that the 300 Watt unit?
Then 300 Watt * 100 hours = 30 kilowatt-hour.
Check the price of electricity at your utility (those vary a lot), but assuming that it is around 12 cents, then the cost for 100 hours would be $3.60
