Engineering : How Much Power Is Required To Power A Large Family Home
I am doing some research into setting up a wind turbine for my house. I see terms like 'kW hours' for energy or power consumption. If my house uses 1500kW hours of energy per week does this mean i need to run a 1500kW generator for 1 hour to satisfy my power needs? How would i then go about sizing the required turbine needed to effectively power my home? This is all new to me so i can see alot of follow up questions coming/ ~~~ Josh ~~~
