How efficient are wind power companies?

Wind power companies performance including economic and technical characteristics. By using capital and fuel, modified Cobb-Douglas production function was introduced. Out of 78 companies, 34 were fully efficient, 24 weakly efficient and 20 inefficient. Identifying factors that will enhance the efficiency of wind power companies.

Why are wind power companies specific in production of electricity?

Wind power companies are specific in production of electricity primarily because they do not cause the cost of energy resource or fuel and require a minimal (or not at all) labour force in electricity generation from wind power.

What are the different types of wind power generation?

In general, the winds blowing across the Earth can be categorized into two main types: onshore winds and offshore winds, thereby making wind power generation consist of onshore and offshore wind farms. There are a wide variety of studies in the literature related to onshore wind turbines [3, 4] and offshore wind turbines [5, 6].

How to evaluate relative efficiency of 78 wind power companies?

Evaluating relative efficiency of 78 wind power companies is implemented by input-oriented BCC model that indicates variable returns to scale. Their relative efficiency result, as well as the country to which they belong, is listed in the following Table 4. Table 4. Relative efficiency of 78 wind power companies (DMUs).

How effective is solar and wind generation?

The efficacy of meeting electricity demands with generation from solar and wind resources depends on factors such as location and weather; the area over which generating assets are distributed; the mix and magnitude of solar and wind generation capacities; the availability of energy storage; and firm generation capacity 11, 12, 13, 14, 15, 16.

What are the current trends in wind power generation?

Furthermore, the current trends of wind power generation indicate that more advanced and rapid progresses are required to be made in wind energy conversion-related engineering methods and technologies to smooth transition towards the goals.
