So this guy (and the makers of the large scale wind turbines for grid power) try to account for that by having the wind turbines' propellers automatically change shape to reduce how fast the wind turns them when wind speeds exceed the usual amount. I think someone came up with that idea around 1900.
But the primary problem with self sufficient energy systems for the home is the batteries. I forgot what the prices I was seeing was, but it was looking like I was going to have to spend between $5,000 to $10,000 dollars to get a decent battery system.
And then I had the worry of where I would put them so they didn't burn everything down if they caught on fire.
Still working on the idea, but a home energy system is a back burner project for me now.
See my post # 33 on how I got around the cost of home batteries issue. For what it’s worth, mine cost about $1K per kWh storage, before the 30% solar tax credit (which artificially inflated my price anyway so the tax credit hurt me as much as it helped me like all subsidies do). So in the end it came out to about $700 per kWh storage.
