They can supply about 50% of a homes electricity usage, as most is below
1.1kW. If using below 1.1 kW it turns the meter backwards. Grid-tied.

This brings into question the safety of using such generation devices.

Generators should be isolated from back-feeding onto the supply network,
and afaik no meters are yet available to allow the "export" back onto the
network for a domestic customer.

I spotted an article about an ex-environment minister (?) Donald Dewer I
think ? - who was extolling the virtues of being the first to use a "home
generation windmill" that simply needed to be plugged into a 13A socket,
but no mention was made of a method of isolating that supply from the
network.


There are several wind turbines for home/small business use that drive back
into the grid and turn the meter back, albeit not at a 1:1 rate. But none
use a 13A plug and socket fortunately !
