A typical home runs around 3000 watts per hour on average. They may well peak at 20,000 watts. If you have a generator that supplies 100 KW's an hour the number of homes that could be powered will vary from 5 to 33. Here is where the issues start.
You have to be supplying power to cover the possible use of any of these homes. The max possible loading is 20 KWH so, we can only actually plan on 5 or 6 homes to be powered. This is why commercial power is based on max demand and not just average loading.
The problem gets MUCH worse if you are getting this 100 KWH from wind or solar. A 100 KWH wind system is based on 28 mph wind. If the system gets winds over 32 MPH, the system supplies nothing. If the wind goes down to 14 MPH, the 100 kWH system supplies us with 10 KWH (10%). To cover these variances we need to have a fossil fuel plant running at 90 KWH just in case the wind varies so we can instantly transfer loads. Solar is similar. The average 100 KWH system puts out about 200 KWH hours per day. The rest must be made up from fossil fuel.
Bottom line is that if the 100 KWH is from "green" energy, the answer is almost a home on average.

∙ 13y agoPretty much, just one. Your 100 watt lightbulb uses one tenth of a kilowatt every hour. Ten light bulbs on use 1 kilowatt of power in one hour. When your water heater runs, it takes about 20 minutes to use 1 kilowatt. One kilowatt goes quick and is nothing. At around 10 cents per kilowatt, it takes a while for your power bill to add up.

A typical home might use an average power of 1-2 kW through the year. But homes sometimes draw more than that and the load can go up to 10-15 kW for one home.

∙ 10y agoOne home needs a supply that can give 14-15 kW, but with a group of 30 or more houses the average would be about 3 kW per house.

How many kilowatt hours does a 100 watt light use in 20 hours?
First let us convert the power of the bulb into kilowatts.A kilowatt is 1000 watts. We have one tenth of that. So 100W = 0.1kWTo work out the kilowatt hours we simply multiply the power in kilowatts by the time the bulb is on for (in hours):0.1kW x 10h = 1 kWha 100 watt bulb uses 100 watts of power. In ten hours it uses 100x10 watt-hours, or 1 kilowatt-hour. A kilowatt-hour is also called a unit, and units are what you pay for.
How much electricity load you can drive on 1 kilowatt?
You could power ten 100 watt light bulbs.
How much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
What does kilowatt hours mean?
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
How much energy does a 100 watt light bulb emit in one minute?
I would have to guess, 100 watts. Power consumed is equal to P I E. P = Amps (I) X Volts (E). Power is measured in watts, or typically, as read on your energy bill, Kilowatts (kw, where 1 Kw = 1,000 watts). So, 100 watts/120V (which is the typical American system) = 0.833 amp (I). Your typical power meter, by which the power company reads your monthly bill, measures amps. Also, 100 watts is 1/10 Kw, or 0.10 kw/hourAnswerFirst of all, you do NOT consume power; you consume energy. Energy is measured in joules, so power is measured in joules per second, which is given a special name: the watt.So there is no such things as 'watts per hour', as this would mean 'joules per second per hour' which, obviously, is nonsense!So, your question should ask, "How much energy is consumed by a 100-W lamp in one hour?" Well, if one watt represents one joule per second, then the lamp will consume 100 x 60 joules in one minute and, therefore, 100 x 60 x 60 joules in one hour. That is, 360 000 joules.Electricity companies usually measure energy in kilowatt hours, rather than in joules. A kilowatt hour is defined as "the energy consumed, in one hour, at a rate of one kilowatt'. You can think of a kilowatt hour simply as being a very big joule! Since 100 W is 0.1 kW, we can therefore say that the lamp must consume 0.1 x 1 = 0.1 kilowatt hours during a period of one hour.

How much electricity load you can drive on 1 kilowatt?
You could power ten 100 watt light bulbs.
How much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
A 100 watt light bulb left on for 24hrs how many kilowatts does it draw in a thirty day period?
1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours

What type of energy is used in a doorbell use?
This snippet is taken from the New England Breeze Newsletter (http://www.newenglandbreeze.com/nl/TEM20080901.html): There are about 5,000 homes in Hudson (MA). Lets assume that 80% of the homes have working doorbells. 80% x 5,000 = 4,000. Let's also assume that all the doorbells draw 3 watts (I bet the older ones draw more). 4,000 x 8,760 x 3 / 1,000 = 105,200 kilowatt hours per year - enough electricity to power 10.5 average homes for a year. Ouch. Want scarier? As of the year 2007, the US Census estimates that Massachusetts has approximately 2,700,000 households. Again, assuming 80% have working doorbells like mine, that's 2,160,000 doorbells using 3 watts of power. 56,764,800 kilowatt-hours or 56.7 megawatt-hours of electricity to run Massachusetts' Doorbells. Enough to power 5,676 average homes for a year (all of Hudson's homes in fact). How about the nation? The US Census estimates 127,901,934 homes. Using the same 80% assumption, that's 2,689,010,261 kilowatt hours. Enough power to run about 268,900 average homes for a year. (95% of the homes in Alaska or 100% of the homes in Wyoming). Nationwide, each kilowatt-hour of generated electricity is responsible for about 1.34 lbs of carbon dioxide. 2,689,010,261 kilowatt-hours leads to 1,801,640 tons of carbon dioxide in our atmosphere... for doorbells.
What is the power output of 100 kw power plant?
Your question shows the importance of using the correct symbols, because your symbols are incorrect and, therefore, your question is confusing.So, are you asking how many milliwatts (mW) there are in a kilowatt (kW), or are you asking how many megawatts (MW) there are in a kilowatt(kW)?Notice that the symbol for a watt is an upper-case W. The symbol for a milli is a lower-case m, and the symbol for a mega is an upper-case M.If the former, then there are one-thousand milliwatts in a watt, and there are one-thousand watts in a kilowatt, so there must be one-million milliwatts in a kilowatt.If the latter, then there are one-thousand kilowatts in a megawatt, so a megawatt must be one-thousandth of a megawatt in a kilowatt.
How many peoples homes were ruined in the boscastle floods?

How many kilowatt hours are used to light a 100 watt light bulb for 1 hour?
Remember that 1 kW = 1000 W So 100 / 1000 = 0.1 100 W = 0.1 kW You take the power - the wattage of the lamp, and multiply with how long it is lit. A 100 W bulb - 0.1 kW - will use 0.1 kWh in one hour. Or 1 kWh in 10 hours. Or 10 kWh in 100 hours.
How do you convert megawatt hours to kilowatt hours?
divide by 100
