- jonsen 6y agoTake a 3.6MW generator. That is 3.6MWh per hour. As we have 3600 seconds per hour, it’s 1kWh per second. Say rotation is one per second, it’s 1 kWh per rotation for a 3.6MW generator. A few kilowatthours per day for an average home?
- yread 6y agoI live in an appartment (still counts as a home) and consumed 6.6 kWh/day on average. The very large turbines don't do 1 rotation per second (wiki [0] says 5-20 rpm). So, totally doable with a 14MW wind turbine [0] https://en.wikipedia.org/wiki/Wind_turbine_design https://en.wikipedia.org/wiki/Wind_turbine_design
- MagnumOpus 6y agoThe average electricity consumption of a UK home is 8 to 10 kWh per day (or 330-400 W if you will).
- ndonnellan 6y agoI doubt the rotation speed is 1/s, that would imply pi*220m/s at the tips or 2488 km/hour! Based on animations, it looks more like 1 rotation per 20 or 30 seconds. 20-30kWh seems very reasonable for a house's consumption.
