Fossil fuels are used for two reasons: on average, they are cheaper per kWh, and the infrastructure is already in place.
There is no connection between the two. Crude oil is used to make fuels. kWh is a method to measure electric consumption.In today's world, with "green" technology the number of gallons of fuel oil per kWh is increasing dramatically. This is because fossil fuel plants now run to provide backup power for these green systems. This power is not used, but the fuel is still burned. Net result is more fuel consumption, not less. Green is not nearly green, compared to the old fossil fuels.
Coal cost about $o.o54 cents per kwh
$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 cost of electricity in Minneapolis is about 6.5 cents per KWH.
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.
In general, hydroelectric power generation is much cheaper than plants using fossil fuels. In the second attached link, it is stated that the average operating cost for a hydroelectric plant is around six cents per kilowatt while an fossil fuel power plants operating cost average is above 2 cents per kilowatt.
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.
At 10 cents per kWh (Kilowatt hour), one 100 watt incandescent light bulb ran for 24 hours straight will cost 24 cents a day. $7.30 a month, $87.60 a year. kWh = (Watts Used * Hours per Day * Days per Month) / 1000 Cost per Month = kWh * Cost per kWh
First, divide watts by 1000 to get kilowatts: watts / 1000 = kW Then multiply kilowatts by the hours of usage to get kilowatt-hours kW * hours = kWh Finally, multiply kilowatt-hours by the cost per: kWh * (cost per kWh) = cost to operate
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.
