1. Energy Consumption at Home

2. Units of Energy Watt – unit of power Kilowatt is equal to 1000W
Light bulbs measured in W
Kilowatt is equal to 1000W
Kilowatt hour (kWh) – 1000W used in one hour

3. Conservation of Energy
Incandescent – 95% of energy in is given off as heat Compact fluorescent lamps (CFL) – are more energy efficient and last longer Light emitting diode (LED) – are even more efficient and last the longest Cost the most

5. Electrical Safety Handle electronics carefully
Some electronics retain charge even after they are unplugged

6. ENERGY STAR and Energuide
is a voluntary partnership between the Government of Canada and industry to promote energy efficiency. Meets a code.

9. Electricity Usage Cost
Every time you plug in an appliance or turn on a switch, electricity is being used.
Smart meters send usage of electricity on a house by house basis

10. Electrical Energy Consumption
Amount of energy used is calculated in kilowatt-hour (kW●h)
If a microwave is 0.8 kW and the oven is turned on for half an hour
E = 0.8 kW x 0.5h = 0.4 kW●h
To calculate cost you multiply the energy consumed (kW●h) at the cost per hour (which can vary depending on time of day).
There are additional charges as well like delivery costs and taxes.
