0.85 as the rest is watt-less current.
It results from the excepted norm for Power Factor and produces a 15% higher carbon footprint.
But hey! It's more costly to achieve unity so get the suckers to turn off a bulb or two. Don't worry about the waste or the cost of buying and producing waste when we generate it.
They will never know about it anyway.
