A few weeks ago, I was driving with my mother to a town about two hours away from where we live. On the way, we passed a large field of windmills. Earlier today, I saw a video clip with some windmills in the background. I decided to look into it just a bit more.

Wind energy works by harnessing the kinetic energy of wind, and using that to power turbines that generate electricity.

At a glance, this is a really good source of energy. However, it would be unfair to only go an inch deep. So, here are the pros.

It causes no pollution, which will help get the Earth back on track with this global climate change thing, and this energy is renewable, because wind generates (in short) from the different atmospheric pressures created by the convection currents in the air. One turbine can power up to 600 homes, and wind energy has lowered the cost of energy and will continue to lower it, because the operation cost of a turbine is extremely low.

Unfortunately, there are some cons like this source is not very reliable, because wind is not incredibly constant and fluctuates quite a bit. Also, since the turbines are spinning, that creates noise and also can hit and kill anything that flies by, like birds and bats. And though the operation cost is low, actually manufacturing and installing these windmills requires massive upfront investments. Some people also don't like the way they look, but when the earth is crumbling around us, I think we can deal with that.

I think it is too soon to say. Sure, the pros outweigh the cons, but not really by enough. It would be wise to give these a chance and change it later if it turns out to not be a good idea.

This could work.

  2. There are completely valid arguments to be made for both sides. However, I'll play the devil's advocate here. In a free-market system, the energy source with the least externalized costs will be the one that sees use. In accordance with the U.S. Energy Information Administration's 2013 cost estimates, wind energy is brutally beaten in overnight costs by far cheaper natural gas sources (~$5000+ extra in $/kW). Luckily, wind power is cheapening by the year, and may just challenge natural gas in the coming decade.
