Pros and Cons: Wind Power

Remember when I wrote the pros and cons of nuclear weapon?

Well, today I would like to discuss the advantages and disadvantages of wind power, an up-and-coming alternative energy source. It's one of the lesser known sources of energy, but yet I think there will be many opportunities in the future to utilize it.

Basically, the energy comes from spinning wind turbines. As the wind blows through and turns the turbines, electricity is generated. I'm not too familiar with the details, but that's the gist of the operation.


1. It's definitely renewable - infinite, you could say. I don't believe that we'll ever run out of wind (and if we do, we have bigger problems to worry about).

2. Little if any pollutants and greenhouse gas emissions. Besides the emissions caused by the construction of equipment, this energy is green and clean.

3. Wind power is pretty safe - there aren't really any risks involved.

4. Can produce power anywhere where there is wind, so the U.S. wouldn't have to be dependent on a foreign source.


1. It can't produce enough power on its own, because the wind isn't always blowing! I guess you could say it is reliant upon the weather.

2. Dangerous to birds. Birds can get caught in the turbines. However, I think this harm to animals is a lot less than the harm ultimately caused by fossil fuel usage.

3. Something called "visual" and "noise pollution." Basically, these "wind farms" look ugly and produce noise. It's not that much of a disadvantage in my opinion, but I guess my mind could change if I lived next to a wind farm.

So, to sum it up, wind power isn't really that bad at all, but it can't stand alone as an energy source. I think a combination of wind, solar, and hydroelectric power would probably be sufficient, though we'd probably need some type of heavy duty power source such as nuclear power to rely on until the other sources become widespread.

So, what are your opinions on wind power? Do you believe it should be a part of our energy future?
