they produce enough noise that they can't be placed close to residential zoneing. A youtube video isn't going to prove that otherwise, i've driven past wind farms what are noisy as forget.
That puts them outside the grid, meaning lines need to be layed between them and the grid, this ups the maintenance cost (and lowers efficiency). Wind energy over here at least is one of the most expensive forms of energy.
Solar and nuclear energy are the way of the future. Wind energy is a waste of time and energy. They can't be used when wind is low, they can't be used in high wind either.
(that design is only a design, lets see one of those that actually works (it wouldn't))
I show you a site with supposed facts, you obviously have access to the internet, which as a wide variety of facts about wind turbines, and yet you're still acting like a moron who believes in single instances governing entire lives. Maybe the wind farm you drove past had, oh, I don't know, older wind turbines?
And I'm sorry to burst your bubble, but when they add a new power plant of any denomination, they have to sort of hook it up to the power grid. I know, it's a big leap from magical juices flowing from big tall smoke stacks straight into your outlets, but it's true, electricity costs money.
Wind energy is very obviously being used today, and is deemed efficient enough to nearly run 1% of the world's infrastructure. And the industry is growing.
