How is Energy Measured?

Two Common Units for Energy Kilowatt-hours Gigajoules

The Kilowatt-Hour (kWh) 1 kWh is the amount of energy used by a 1000 Watt appliance if it runs for one hour Examples Ten 100 watt lightbulbs on for one hour (100 W = 0.1 kW) – 10 * 0.1kW * 1 hour = 1kWh 5000 watt clothes dryer on for 12 minutes (5000 W = 5 kW) – 5 kW* 1/5 hour = 1kWh One 100 watt lightbulb on for ten hours – 0.1 kW * 10 hours = 1kWh

DIY Electrical Energy Audit: Room By Room Accounting Excel Spreadsheet Available Here:

What you will learn from the room-by-room accounting: 1) Energy use trends in your house Really makes you think about energy waste 2) What things in your house draw the most power and what use the most energy (not necessarily the same) Example: Dryer at 5kW 45 minutes per week: 5kW * 0.75 h = 3.75kWh/week Vs. Computer at 200 W for 40 hours per week: 0.2 kW * 40 = 8 kWh/week 3) What things in your house have high phantom loads

Post Audit Analysis Identify Biggest Power Consumers – E.g. Dryer: 5 kW. A/C: 3 kW. Stove: 2 kW Identify Biggest Energy Consumers Identify biggest Phantom Loads

More Energy Saving Tips to Incorporate into Your Plan: Turn things off when they are not in use Replace incandescent bulbs with CFLs Get a programmable thermostat – Set thermostat to no less than 25C in summer Even higher when house is unoccupied – Set thermostat to no more than 20C in winter Even lower when house is unoccupied Use a toaster oven instead of regular oven for small meals.

General Energy Savings Tips Insulate ducts and hot water pipes If you need to make any upgrades to your home heating or cooling, have a professional home energy audit (
