Completed a 2000 watt grid-tie windmill system in October. Although the local building code people were reasonable, my utility company, REA, charged me 792 bucks to get hooked up leagally. At around 150 bucks, the local building code people inspected my windmill pole foundation, did the electrical inspection, or basically did all the work. Then they sent that info to REA. Then REA had me fill out a REAP agreement, plugged in an additional meter to measure my wind power which I had installed the meter socket, and programed my existing smart meter for an addtional 792 bucks.
Now I'm thinking about solar but the thought of dealing with them is making me think twice.
I have a 312 foot diameter Gamesa behind my house and yes it makes noise. A small hum from the nacelle and a small swishing sound when the bottom blade passes when standing under it. At my house 1/2 mile away, I hear nothing.
On the other hand, when a Harley Davidson goes past my house, no one can talk until it's 3/4's of a mile away. There's no comparison.
I was told that at the turn of the last century here in Johnstown Pa, that the city was heated by steam from a central coal plant. The business's got charged my the amount of water that was condenced from their building.
