# How many kilowatts does a house use in a day?

If you are a perfectly average American living in a perfectly average household, your monthly electricity bill will read 911 kilowatt hours (kWh), which costs \$114. But most of us don't live in perfectly average households.

### How many watts do I need for my house?

Homeowners can often power most household appliances using between 3000 and 6500 watts. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your needs. If you have a larger furnace and/or a well pump, you will likely need a 5000 to 6500 watt generator.
• #### How many watts is a typical refrigerator?

Find the voltage and amperage of the refrigerator; for instance, you may see "115 V" and "6.5 amps." Multiplying these two numbers tells you how many watts your refrigerator uses -- in this case, 747.5 watts. Smaller refrigerators typically use about 350 watts, while larger models use as much as 780 watts.
• #### How do I calculate solar power needs?

To calculate the energy you will use over time, just multiply the power consumption by the hours of intended use. The 20W TV in this example, on for 2 hours, will take 20 x 2 = 40WH from the battery. Repeat this for all the appliances you wish to use, then add the results to establish total consumption like below.
• #### How many solar panels are needed for a 5kw system?

How many solar panels will you need? To make up a 5kW solar system, you need 20 solar panels, assuming you use 250W panels. Each panel will be about 1.6m x 1m, so you'll need at least 32m² of roof space.

### How much is 1000 kWh of electricity?

Here's the formula to figure the cost of running a device: wattage x hours used ÷ 1000 x price per kWh = cost of electricity.
For example, let's say you leave a 100-watt bulb running continuously (730 hours a month), and you're paying 15¢/kWh. Your cost to run the bulb all month is 100 x 730 ÷ 1000 x 15¢ = \$10.95.
• #### What does 1000 kwh mean?

One kilowatt is equal to 1,000 watts. Your electricity company charges by how much electricity you use per kilowatt hour (kWh). To put it simply, this means it measures the number of kilowatts you use over time. For example: A 100 watt light bulb uses 0.1 kilowatts each hour.
• #### How big of a generator do I need to run a house?

Homeowners can often power most household appliances using between 3000 and 6500 watts. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your needs. If you have a larger furnace and/or a well pump, you will likely need a 5000 to 6500 watt generator.
• #### How many kwh does the average home use per day?

In 2016, the average annual electricity consumption for a U.S. residential utility customer was 10,766 kilowatthours (kWh), an average of 897 kWh per month. Louisiana had the highest annual electricity consumption at 14,881 kWh per residential customer and Hawaii had the lowest at 6,061 kWh per residential customer.
