Wind Energy example essay topic

For human development to continue, we will ultimately need to find sources of renewable or virtually inexhaustible energy. It's difficult to imagine this, but even if we find several hundred or even thousand years of coal and natural gas supplies, what will humans do for the next 250,000 years or so after they are depleted? Even the most apparently 'inexhaustible's sources like fusion involve the generation of large amounts of waste heat -- enough to place damaging stress on even a robust ecosystem like Earth's, at least for the organisms that depend upon stability of the system to survive. We are engaged in a sort of world-wide biological experiment, with our descendants as the subjects. Our present habits of energy use are shaping an entirely different earth than the one with which we are familiar. When these changes begin to be expressed, there will be no one to preserve the familiar and there's no guarantee that things will turn out the best for our particular species.

Some have looked ahead and seen this. But they usually don't get much support from societies that are too busy trying to 'make do' and that are rushing backwards into the future -- in other words, every society on earth. One of the areas that suffers because of this backward thinking is the development of renewable energy sources -- and the topic of this section: Wind Energy Conversion. There's a lot of underlying popular support for wind energy and the other renewable's in the United States. But there's also a lot of apathy as well.

We are blissfully sedated by low conventional energy prices and are gulping down the few remaining years of cheap natural gas and Mid East oil. As we do this, the inertia of global warming is inexorably building. What drives the continued development of mechanical devices like wind turbines in the face of this widespread lack of support? In the case of wind turbine technology, I suspect that part of the reason for persistence of this vision is how accessible wind turbines are to the understanding. They are personal in a way that almost no other form of power generation is. This 'personal's cale has been both the blessing and the curse of wind power development.

The field tends to attract people who are committed, creative, and passionate. It also attracts a few people who are a little too much of all of those things, to the point that sometimes the grounding of reality is lost. Both of these tendencies will be evident in this brief history of wind power development. Wind power will probably succeed or fail based on the ability or inability of its proponents to bank the fires of 'Romance' and focus on defining wind generation's role as a practical alternative to conventional generation sources. Wind energy conversion is a fascinating field to study, if only because its past has been so checkered and its exact future is so uncertain. Unlike the aerospace industry, the computer industry, and almost any other successful industry you can name, wind energy -- the leading mechanically-based renewable energy for much of man's history -- has never made anyone rich for long.

But unlike many of these other industries, it has been around for thousands of years. It's a technology that has been reinvented numerous times. We are left with the promise and the drive to succeed despite daunting (and sometimes puzzling) obstacles.
