As of September 2008 the cost is 28.22 cents per kilowatt hour. This was calculated taking the total electric bill and divide it by the number of KWh.
Puerto Rico is useless. as are Puerto ricans.
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
Coal cost about $o.o54 cents per kwh
To calculate the cost, you need to know the cost per kilowatt-hour (kWh) from your utility provider. Multiply the kWh of the shower unit (9 kWh) by the duration (0.5 hours) to get the total energy used. Then multiply this by the cost per kWh to get the total cost.
$14.00 + 14.300c is the cost per kwh in North Haven Connecticut
The energy cost depends on the size of the system. Large concentrated systems cost $0.10-$0.15 per kWh. Medium and small scale systems can cost from $0.25-$0.50 per kWh, when averaged.
The population density of Puerto Rico is approximately 892 people per square mile.
Puerto Rico has the infant mortality rate of 7.73 deaths per 1000 live births.
It is $17,100 (2009)
Find the consumption of power in kwh for a given period. Find the corresponding cost. Divide cost by the total kwh. Most energy companies indicate the average kwh cost incurred for a given month in their monthly statements.
Multiply the figure by your cost per kwh. The kwh cost is available from your local power company or utility. For instance, if a kwh was priced at 7.6 cents/kwh, then the total cost would be a bit over $30.
To calculate the cost of using a 40-watt power device per hour, you need to know the cost of electricity per kilowatt-hour (kWh) from your utility company. You can then convert the watts to kilowatts (40 watts is 0.04 kW) and multiply that by the number of hours used to find the kWh consumed. Finally, multiply the kWh consumed by the cost per kWh to determine the total cost.
