A kilowatt hour is a unit of work or energy, and the product of power in kilowatts and time in hours.
So, for example, it can be the work done, at a rate of one kilowatt, over a period of one hour.
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
The cost of electricity in Minneapolis is about 6.5 cents per KWH.
1 million kWh = 1 GWh, so 927.7 million kWh = 927.7 GWh.
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
Your question is not very specific, as 'oil' is a very broad term. Crude oil is never burned straight, it is always processed. I will assume gasoline is what is being used. Gasoline produces 36.6 kWh of power per one US gallon. Therefore: (36.6 kWh/ 1 gal) = ( 1 kWh/ X gal) (1 * 1) / 36.6 = X X ~= 0.0273 gallons So it takes about 0.0273 gallons of gasoline to produce one kWh of power. Some digging on various sites tells me that about 55% of crude oil (per gallon) gets processed into gasoline. So we take our number of gallons and multiply it by 155%: 0.0273 gal/gas * 1.55 ~= 0.0423 gal/oil So it takes 0.0423 gallons of oil to generate one kWh of power.
Coal cost about $o.o54 cents per kwh
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.
The energy output from LPG gas is as follows :12.9 Kwh/Kg & 7.5 Kwh/Ltr. (Details from "http://hypertextbook.com/facts/2002/EricLeung.shtml")
The cost of a kWh is 0.1029 or 10 and a third cents for every hour that you use.
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
The cost of electricity in Minneapolis is about 6.5 cents per KWH.
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.
$0.08 / Kwh for avg residential
$14.00 + 14.300c is the cost per kwh in North Haven Connecticut
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.
1 kwh = 3,600,000 Joules
1 million kWh = 1 GWh, so 927.7 million kWh = 927.7 GWh.
