My household consumption is 8kWh per day, so I'm saving 1.67kWh of that

my bill, on my site, with my wind conditions.
Does that take into account capital cost and replacement? My understanding
of the B & Q Windsave is that it takes about 10 years to recover the initial
cost but the lifespan of the unit is said to be 10 years. If that is true,
then the savings are nil.
