rooftop wind turbines are a waste of time. Reliably produce 5 8ths of fuck all. To produce ANY useable power your turbine needs to be way the hell up in clean airflow: in a suburb that's a minimum of 12 m, so practically un-doable, or godamn ugly at the least. And to produce sufficient power to recharge an EV you need a decent sized wind turbine. A 1kw one wont cut the mustard. They only produce a kw in a hurricane.
Back in 2006 when I studied off grid shit my tutor stepped us through the math of every home in NZ (say 1.5 million homes) having a rooftop turbine, and then proceeded to show us just how many big boy turbines you needed to replace them with. 29 was the number. 29x3mw turbines.
