Buffett company could buy windmill farms

MidAmerican Energy Co., the Iowa utility controlled by Warren Buffett’s Berkshire Hathaway Inc. may buy wind-power assets from FPL Group Inc. rather than starting from scratch with its own windmill farms. Such a deal would help MidAmerican jump-start a plan, filed with state regulators, to add 1,001 megawatts of wind power capacity in Iowa, Dean Crist, the company’s vice president for regulatory affairs, said today in an interview.

How Wind Turbines Work

How Wind Turbines Work Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

Wind Power

Definition...Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines.

How it Works...The Wind Resource
The wind resource–how fast it blows, how often, and when–plays a significant role in its power generation cost. The power output from a wind turbine rises as a cube of wind speed. In other words, if wind speed doubles, the power output increases eight times. Therefore, higher-speed winds are more easily and inexpensively captured. Wind speeds are divided into seven classes–with class one being the lowest, and class seven being the highest. A wind resource assessment evaluates the average wind speeds above a section of land (usually 50 meters high), and assigns that area a wind class. Wind turbines operate over a limited range of wind speeds. If the wind is too slow, they won't be able to turn, and if too fast, they shut down to avoid being damaged. Wind speeds in classes three (6.7 – 7.4 meters per second (m/s)) and above are typically needed to economically generate power. Ideally, a wind turbine should be matched to the speed and frequency of the resource to maximize power production.

Wind Power

Wind power is produced by using wind generators to harness the kinetic energy of wind. It is gaining worldwide popularity as a large scale energy source, although it still only provides less than one percent of global energy consumption. The articles listed below explore wind power and its usage around the world.
