It's the amount of energy exerted over a certain period of time.  Or how much energy you spend to achieve a certain task.

power #175, gas $70 summer & 240 winter (gas heat), water     $85, insurance higher in CA so I can not help there we do not have earthquakes just hurricanes. \nThe real expenses come from upkeep - power washing, painting, \ncarpet cleaning, replacing appliances & heating units ( I just paid $8600 for air conditioning unit ), water heaters. I built my house\n 8-1/2 years ago & I have replace air conditioning, dishwasher, water heater, carpet downstairs, had it painted. I would quess I have spent in maintenance & repairs around $18,000 in the last 5 years. More than I expected for sure.\nGood luck with new house, I love mine.

The cost of solar power in most locations is about .37/kwh as fossil fuel costs increase and solar power becomes more efficient it will probably be used on every corner of the Earth (figuratively speaking, I know the Earth has no corners).\n\nHere in Florida last year we had storms knock ou power to millions of households. Solar energy systems not only survived, but those homes were the only ones with power!

energy is the capacity that an object has for performing work.  Work is a force times a distance.  A similar comparison might be your bank account balance and dollars.  While both are related and have the same units, your bank account is the capacity that you have to spend money.  The big difference is of course, you can never have a negative balance on the amount of energy in a system.

Assuming you're in the UK then it varies depending on whether you pay as you go (key meter) or are billed monthly or quarterly.  It also varies as between suppliers.\n\nHowever as a general guide EDF (Formerly London Electricity) charge 15.11p per day as a standing charge and 9.60p per KW hour for the electricity you use.  \n\nIf one forgets the 15.11p daily charge then burning 10 100 watt light bulbs for one hour will cost you 9.60p.  Which is the same as having used 1000 watts of electricity.

sempra energy. good luck!

therms are still used - but they are converted to kilowatt hours and you are charged per KWH the same as electricity and you can now compare the price of gas and electricity easier - the calculation is on the back of the gas bill.

1.68 cents / kWh, in 2004. Cost consists of fuel cost + operating and maintenance cost.

There are different type of tarrifs for different consumers. so any one calculation would not suffice. You have to obtain schedule applicable to type of connection which you have and calculate your bill accordingly.or post copy of your bill from which schedule followed could be understood and method of calculation followed could be explained.\n\nGenerally charges for domestic connections are based on\n(a) Minimum charges based on load sanctioned. if you have a 6 kW connection and rate per kW is Rs. 50/- per month, minimum charge would be Rs. 300/- per month. Now let us say you have consumed 500 units ( kWh or kilowatthours i,e unit of measurement of electricity consumed) in a particular month and charges are Rs. 4/- per unit for first 200 units and Rs 5/- per unit for next 200 units and Rs. 7/- per unit for remaining units, your energy charges would be 2x200+5x200+7x100=2100. Now energy charges being more than Minimum charges energy charges would be levied.\nTo this following additions are also made depending on tarrif schedule.\n\nMeter Rent\nElectricity Duty.\nSurcharge.\netc.

It depends on where you live.  The cost of electricity on the power grid ranges from about 4 cents per kilowatt hour in Kentucky to about 14 cents per kilowatt-hour in New York City.   You would need to find out what the cost per kilowatt hour is where you live and multiply that by the number of kilowatt-hours you would use in a month.\n\nTo determine the number of kilowatt-hours you would use in a month, multiply the power (in watts) of each appliance by the number of hours that appliance is being used and divide this by 1000.  For example if you use eight 100-watt light bulbs an average of 5 hours a day than, they would account for 8 x 100 x 5 x 30 (days in a month) = 15000 watts/1000=15 kilowatt-hours.  If you don't know how many watts the appliance uses, multiply the number of amps by the voltage the appliance uses; but it is easier just to check the table in the link below to find a typical power useage for each of your appliances.\n\nOnce you've totaled the number of kilowatt hours used (watts x hours used / 1000) for each appliance, multiply that total by the cost per kilowatt-hour in your area.\n\nThe biggest influences on your electric costs or usually the water heater and heat and air, and possibly the oven if it is used a lot.  Using a space heater a lot can effect it a lot.

Power Consumption is the rate at which you use power (watts).\nPower used in your home is measured in killo-Watt hours and is priced as $ per KW-hr used. \n\nSo at $.40 per kW-hr rate and you use 300 kW-hr in a month then your cost would be $.40 x 300 = $120\n\nnote: killo = 1000

My dear asker\nThe solar energy costs only the big amount of initial investment. And then the maintenance cost is quite low. The combination of both costs is lower than that used with the conventional fuel. \nWhat you need is first you construct the solar structure to collect the sun's energy, store it and distribute it to the place of use. After this initial investment, what you need is only to keep it in good conditions. Unlike using the conventional fuels, you don't need to buy more fuel to run your machhine.\nI want to install the new type of solar collector if I can later since it saves money long time.

Electricity is charged by the kilowatt (1000 watts) hour.  A 60 watt bulb uses 60/1000 hr. That's .06 times price per KWH.

Although the term "energy budget" is widely used, the flow of energy in and out of the Earth is actually measured in units of power (watts), not units of energy (joules). Therefore, "power budget" would be a more accurate term.\n\nWell, ideally, the Earth's Energy Budget should have been at equillibrium; but due to the effect of Greenhouse gases, deforestation, Ozone leakage, etc. the equilibrium has already been disbalanced and the net Earth's energy content is increasing steadily. Added to this grave problem are the Solar Storms, which are increasing in number and intensity; increased amount of meteor shower; increase in the sun's radiation, etc. are calling for the end of life in our Solar system.

Changing the economics of Renewable Energy & The Hydrogen Economy.  Energy is the corner stone of the 1st World's economy.  Without energy no funds are available for any liberal agenda.  Most of the 1st World's products require energy tobe consumed as well.\n\nThe fact that most people feel they are entitled to their present life style implies future civil unrest if the cost of energy disrupts the economy.

hi,\n\nwith any kind of solar feature, the payback period is just the amount of time it takes until your energy savings surpass the installation cost.\n\nas for a sunspace, calculating how much energy they trap is a not straightforward problem.  there are some papers on this subject that all use a fairly complex software simulation to figure this out.  needless to say, this also depends a great deal on the shape and area of the sunspace, the kind of glass and/or coatings on it, your location (which determines average solar flux and temperatures), the materials involved, and a bunch of other parameters.\n\nhowever, if you ahve a look at this link:\nhttp://www.esim.ca/2002/documents/Proceedings/Session%203a-4.pdf\n\nyou'll see that they have done just such a simulation, and calculated the yearly energy savings for a 10ft x 10ft sunspace made of a variety of kinds of materials and in a few locations across canada.  you can see that the variations run from 11 MWh (37 million BTU) to 17 MWh (58 million BTU).  \n\nelectricity costs vary widely, but i'll use the US national average from nov. 2005, which was 9.74 cents per kWh.  this means that the 11MWh case generates the amount of heat that would cost $1071.80 to generate electrically.  the 17MWh case generates $1655.80 worth of electrically powered heat.\n\nif, however you heat your home with gas, which costs right now around $8 per million BTU, the cost of generating that much heat changes to $296 - $494.  \n\nso, if your installation costs maybe $5000 to install, and you live in a cold climate like ottawa where the savings are $494 per year, then your payoff period is around 10 years.\n\nagain, all this stuff will vary wildly with your specific designs.  \n\nhope this helps!
