Wind energy is a dynamic if invisible resource—the energy available in a moving mas* of air. From grain grinding by simple wind-driven machines in ancient cultures to modern electricity-generating devices, the wind has been tapped to work for us. Wind is a cubic energy resource. As the wind speed increases, the power available increases cubically. This means that it’s very important to get into higher wind speeds, and the way we do that is with taller towers. Regardless of the turbine or tower type, going higher is the tried-and-true, reliable way to increase performance in a wind generator. And the most common mistake in wind electricity is The swept area of a wind turbine is the second most important factor (after the wind resource itself) that determines energy production. The circle “swept” by the blades is the collector area. It’s not possible to get a large amount of energy out of a small collector area. Betz’ theorem says we can only get about 60% of the energy out of the wind before we start slowing it down too much and actually decreasing performance. In the real world, well-designed machines can achieve about half of that. People choose to use wind energy for a variety of reasons, including perhaps the most important one—they want to! More specific motivations include environmental, financial, independence, reliability, and social. Energy and our energy choices have a huge impact on our physical environment. More than half of the electricity used in the United States is generated by burning coal. This coal is sourced by st*ip mining, pit mining, shaft mining, and mountaintop removal. All of these methods of extraction, and the burning of coal, have a deleterious effect on the ground, water, and air, not to mention the health of workers and nearby residents. Other major sources of electricity nationally are natural gas and nuclear energy, both of which have environmental damage and risk involved in fuel extraction and use. While all energy producing endeavors have an impact, wind energy (as well as other renewables) have a lower impact overall, if well
