Question
Interest in harnessing the power of wind as an energy source was revisited in the 1970s around the same time the oil market fluctuated. Since then, the United States has made inroads into developing technologies to efficiently harvest wind power to generate electrical energy. The location of a wind farm is important because wind speed and duration must be fairly constant to be effective. Wind farms are often located on the top of smooth, rounded hills; on flat, open plains; along shorelines; or in mountain gaps where wind is funneled through a pass. Ideal conditions should capture a wind with a velocity of at least 23 km per hour (14 mph). Wind speeds that exceed this value can be dangerous for the windmills. When wind speed is too high, the windmill must be shut down to prevent damage. Most wind plants in the United States are privately owned. The wind-produced electrical energy is sold to the electric companies, where it is transmitted onto electrical grids and made available to the public.
The biggest drawback of wind-produced electrical energy is a limitation in the current electrical grid system in the United States. The transmission lines in the current grid system do not have the capacity to carry the heavy loads of energy produced by wind farms over a long distance.

The best location to place a wind farm would be on flat, open plains, particularly those areas known for consistent and high wind speeds. This assertion is supported by several pieces of evidence from the characteristics of wind energy generation and site selection criteria.
1. **Wind Consistency**: As mentioned, effective wind farms require wind speeds of at least 23 km per hour (14 mph) to generate energy efficiently. Flat plains, such as those found in regions like the Great Plains in the United States (e.g., states like Texas, Kansas, and Nebraska), often experience steady and strong winds due to their unobstructed geographical features. In contrast, hilly or mountainous areas may have variable wind patterns and turbulence, which can create inefficiencies in energy generation.
2. **Space for Expansion**: Open plains typically provide ample space for large scale wind farms without the constraints of nearby obstacles such as buildings or trees that can interfere with wind flow. This space allows for the installation of multiple wind turbines in optimal arrangements to maximize energy capture and minimize wake effects, where the wind speed is reduced behind a turbine.
3. **Ease of Access**: Located on flat land, wind farms can also have easier access for maintenance and construction compared to more rugged terrains. This logistical advantage can lower operational costs over time, making wind energy a more viable and sustainable choice.
4. **Proximity to Existing Infrastructure**: While there are limitations in the current electrical grid system, choosing locations for wind farms that are closer to existing transmission lines can somewhat mitigate these challenges. Regions that are already part of the electrical grid, even if zoned for wind power, would be preferable since energy produced would have a shorter distance to travel to reach consumers.
5. **Case Studies**: Real-world examples support the effectiveness of flat plains for wind energy generation. States like Iowa and Texas have pioneered significant wind farm developments that harness the consistent wind patterns of their flat terrains, making them leaders in wind energy production.
In summary, flat, open plains with consistent wind patterns remain the most suitable location for wind farms, considering factors like wind speed reliability, space for expansion, ease of maintenance, and potential proximity to existing grid infrastructure. This combination maximizes efficiency and energy generation capacity, making wind energy a lucrative renewable resource.
