Quite. The rule of thumb I read somewhere was to aim for the low point of the turbine blade to be at least 10m higher than any obstruction within 160m. You not only get more wind, but steadier wind, improving the lifetime of your turbine assembly.
If your neighbors are far away, too, cutting down the tree might be reasonable.
They aren't. I'm in the middle of a city, and 160m is a pretty fair distance in a city. Even if I wanted to cut down a dozen trees (which I don't) so as to leave clearance for wind turbines, my neighbors on 3 sides all have mature trees as well. Likewise with solar: my neighbor to the south is shading my roof with their trees. (To the north of my roof would be a lot better - too bad I'm in the northern hemisphere.)
It really does come down to residential nuclear. Pretty sure that's what I need.

And their operating costs? The problem with net metering is that you're expecting the utility (i.e., we the ratepayers) to shoulder all the infrastructure costs for free. They're expected to pay you exactly the same cost for your excess electricity as they recoup from whoever they sell it to. There are various costs to being a utility, that's why wholesale and retail electricity prices are so different.
I think it's entirely fair to allow people to sell excess power to the utility - at wholesale. That's maybe $0.03/kWh? And if people don't like that, well, that's what the Tesla Powerwall (or that Sysphus Railroad) is for. Buy one of those, and keep most of the retail value of the energy you've collected. Why should the utility have to bear these costs for something that mainly benefits you?
I guess in the end, net metering is due to a technical limitation - making a meter run backwards at 1:1 scale apparently is easier than deploying a meter that can account the two directions separately. Maybe this is the real reason the utilities are pushing smart meters?
