I'm curious what manner of trees anyone thinks would be tall enough to conceal a wind turbine ;). While wind farms do take up a bit of space, they are excellent for energy and -- unlike nuclear plants -- do not pose a potential hazard to the world. I live in Wyoming, where we have a lot of land that can't be used for farming or anything else due to the lack of water and high clay content in the soil. However, we do have prevailing winds throughout much of the state. Here, wind farms have done very well. The space that has been used for them is still inhabited by local wildlife, and the farms have also created a number of jobs that pay much higher than the state average. Wind and water (hydroelectric) power the entire state and then some. There has also been a push recently for more solar power, and anyone who has done it for their homes and outbuildings have ended up with more than they need. They estimate that it will take about 5-8 years before the cost savings offsets the price of the panels, and most panels have an estimated life span of 30 years.
Is campaigning against wind farms selfish? Possibly, though I'm sure those that do have reasons that are very valid to them. The one thing that I would consider selfish would be to campaign against any type of natural power. Nuclear power may be efficient, but it has proven many, many times that it is not safe -- and when something goes wrong it rarely goes a little wrong, and in severe cases it may take a lot of lives with it and leave a vast radioactive wasteland where the plant used to be.
