This page contains information from Natural Resources Canada's (NRCan's) Stand-Alone Wind Energy System Buyer's Guide that may help you calculate your building's electricity demand.
Typical annual electricity consumption levels in the following charts are approximate values, based on the estimated hours of use per small household. Individual habits and the number of family members will have a large impact on overall energy usage. You can estimate your household hours of television viewing, vacuuming, tool usage, and other activities to determine your annual electricity consumption. Check the reverse side and nameplates of your appliances for Watts of electricity consumption, and use those values if they are different from the information in the table.
Large appliance electricity consumption is based on EnerGuide data for the standard major appliances listed. Manufacturer data was used for the high efficiency appliances.
