<prompt> Human: Sorry a little personal venting involved hereI just got done getting screamed at about the electricity bill in the home I live at by my Sister the house is hers and shes very hormonal and livid because shes pregnant so it wasnt a cake day by any means...Based on Indiana electricity bill rates in rural areas, how much money would it cost for 1 bedroom with 1 ceiling light on 4x 60watt bulbs and 1 laptop constantly plugged in the wall 180watt brick charger with a 2nd monitor main screen and 2nd are both 20 inches to be on roughly 14-16 hours a day -- 30 days a month?Reason being, Im being told Im the only possible reason that this 1400 sq ft house that could ramp up the electricity bill to 300. I usually cant use reason to talk to her as she screams as soon as she feels like her argument is being put to the test, so I want to make sure what is happening is actually true to her claims or if I can actually prove some shit that it cant possibly be me hiking up 50 of the bill.We just moved to Indiana and it has been 2 months in a row its been 300. The rest of the household has 3 commonly used TVs one 42 inch, one 15 inch, one 65 inch with a PS4 for the biggest one that runs everytime the TV is on and the 42 inch runs a PS3 everytime its on. The 2 children my nephews almost everyday leave the bathroom lights on after they use it might be a couple hours at a time with 2x lights because its a split bathroom with sink in one room and tubtoilet in the other. One nephew has a computer he never turns off that has a 400 Watt PSU, though he just watches YoutubeNetflix on it 90 of the time because my nephews arent allowed to play video games unless its the weekend. We have an electric dryer that is modern, a washer that is about 10 years old. The kitchen lights there are 2, one with 1 light bulb and another thats chandelier like with 4 bulbs, probably 60 Watt get used while dinner is being made or while the young ones do homework. The living room light is on generally probably about 4-6 hours in the day on avg depending.I tried to be as specific as possible here with the most commonly used things in the household and we had the same things except the modern dryer running on the same schedule, if not more often because my youngest nephew didnt have school last year, at the old place which was a trailer in Illinois in a trailer park 2 hours south of Chicago and the bill was about half.Sorry if this is a ridiculous sounding post, I just really want to get the the bottom of whether or not Im the core problem of the electric bill so I can get my Sister off my ass...I know, its a personal issue, just asking for some help as I know nothing on how to research this stuff really...  <response>: Electricity is billed in a unit called a kilowatt-hour. Its pretty easy - 1 kWh means that you used 1000 watts for one hour. So, if you have a heater that uses 1000 watts, and its turned on for an hour, that just cost 1 kWh, or 10-15 cents price depends on a lot of factors, so you need to look at the bill. If you have a computer that uses 500W, you run if for two hours to use 1kWh. You can run a 100W light bulb for 10 hours to get 1 kWh. So, hopefully that makes sense. Now you should be able to take the usage of any appliance and figure out its kWh usage over a certain amount of time. Your main electricity users are going to be anything that gets hot incandescent bulbs, dryer, heaters and air conditioning units. Your example items look like about 600W, so 600x1610,000 Wh or 10kWh per day. For 30 days, thats 300kWh. If your rate is .15 per kWh, thats 45. Then theres the fact that some electricity plans jump in cost depending on time of day and how much is used over the whole month. You causing 50-60 in extra electricity isnt out of the question. If your running the air conditioners, your hot body is also causing it to run a little more could be negligible unless youre opening doors or windows to smoke or something. Happy to answer any other questions. Get some LED bulbs for your room and any other heavily used room. That makes a big difference. Edit: those cost estimates for your room are worst case and rounded up. Also, 15 cents is what I consider a high price, but I have no idea where the Chicago market is on power. Another edit: looks like IL has a deregulated electric market which means you choose from a variety of electric companies and plans. Also, your rates might be more around 8 cents... one thing that happens in Texas, is you sign up for an electric contract with a company for a certain price, and after the contract is up 6mo, 12mo they can drastically raise your rates. So if the rates went up when you moved in, could make you look bad?
