There are 100 mW in one KwH
It takes about 4.4 tons of bauxite ore (and about 14000 KWH of electricity) to produce 1 ton of aluminum.
The formula you are looking for is Watts/1000 x hours in the day x cost per kWh.so it is 1,500
A 1000 watt device operated continusouly for 1 hour would equal 1 Kwh.
There are two measures of electricity to know about: kWh, and kW. kWh, or kilowatt-hours, is a measure of total energy use over time. It's like how far you've driven your car. kW, or kilowatts, is a measure of instantaneous consumption, like how fast you are driving at any given second. The average home in Phoenix might max out at around 3 kW or a little more when everything - your computers, refrigerator, lights, air conditioning, etc. - are running. (An individual hair dryer might use 1.5 kW, so don't run those too long.) kW, however, is not how you get billed. Almost all residential properties get billed on kWh, the total amount of electricity they use each month. kWh can be calculated by multiplying kW by the number of hours you used that kW. This is the same as figuring out how far you've driven by multiplying your speed by how much time you spent driving at that speed. In Phoenix, an average house your size might use around 30-40 kWh every day. It could be twice this in the summer when you're air conditioning, and much less in the fall or spring when you're not.
It depends on where you live. You want to know how much Sun you get (solar hours). If you live in Southern California or Arizona, you might get 6 hours per day. If you live in Northern CA or Oregon, it might be closer to 4. First, you take your 1,000 kWh/mo and divide that by 30 to get your kWh/day. 1,000 / 30 = 33.3 kWh/day Then you divide this by the number of solar hours per day your area gets. Let's say 5. 33.3 / 5 = 6.67 kW Last you need to adjust for real world inefficiencies. A good rule of thumb is to suppose approximately 75% - 80% inefficiencies. So increase your system a little. 6.67 kW / 0.75 = 8.9 kW. This is a fairly large residential system, but you can reasonably expect it to cover 100% of your electricity needs if you use 1,000 kWh per month. Want to know how much an 8.9 kW solar system might cost? Go to and play the solar calculator in the related link below. (Yes, it's free.)
The cost of electricity in Minneapolis is about 6.5 cents per KWH.
$0.08 / Kwh for avg residential
Dinorwig is a 'pumped storage' hydro power facility. It has a capacity to produce 1.89GW of electricity, which equates to 6.8TWh. I terms of kWh, this would be 6.8E9 kWh or 6,800,000,000 kWh. (6.8 billion kWh).
It takes one ton of coal to generate an average of 2500 KWH of electricity.
Call your supplier, find out how much for one kWh, then 60 x that price.
4-8 cents
0.17 euro per kwh
Divide the monthly billed charges from the Utility by the months usage in KWH. Monthly Bill divided by KWH (usage for month) = Unit Cost
It depends on how much you waste.It depends on where you live and how much the local public utility that supplies electricity charges per KwH -- kilo-watt hour.
Let's say about 4 rubbles per kwh.
It depends how much you pay for electricity. A 15 Watt bulb would consume around 134 kWh of electricity. In the UK, electricity is around 10p a kWh, so it would cost £13.40 to run the bulb.
Mexico is the 18th largest electricity consumer worldwide, with 200.9 billion kWh of electricity used each year.
