=Why do my parents tell me to turn off the lights?= Objective: Estimate how much electrical energy you consume on a daily basis

Hypothesis: I hypothesize that my family uses about 1000 kWH because we use a lot of energy.

Actual Amount: 766 kWh Total Cost: $165.00



Sample Calculations:
 * Toaster
 * 1200W=1.2kW
 * 50 min= .833 h
 * kWh= (1.2 kW)(.833 h)
 * kWh= 1

Average kWh= Total Cost/ Total Usage of kWH Average kWh= $165/766 Average price per kWh= $.21

What does this cost your parents? (per month)
 * 4.02(kWh) X 30 (days) = 120.60 kWh (1 month)
 * Cost = $.21
 * (120.6)(.121)= $25.20 per month

Conclusion: Being that there are always appliances plugged in at my house, the cost of our electrical bill seems very low in comparison to the amount of electricity we consume. Personally, I use about 120.6 kWh a month which is about 20% of the total electricity used in my house per month. My house consumes a decently large amount of electricity because we are extremely bad at turning off lights when we are not in the room and unplugging appliances when we are done using them. The appliances in my house that consume the most power are the bigger ones, such as the refrigerator, over, and dish washer, that are always plugged in and often in use. If we greatly reduced the amount of power usage when it is unneeded, which is quite often, my family could greatly reduce the total kWh used in a month therefore lowering our total cost spent on electricity. This can be done by unplugging everything that is not in use, and never leaving lights on in a room that is not in use.
