(2015), and Oswald et al. (2008), the contribution of wind power is an insignificant part of whole human electric energy. At least, more than 40% energy still comes from traditional coal burning in Europe (Beckman, 2015). Obviously, the utilization and efficiency of using wind power will be lower in other areas because they do not have the same wind power technology and system like Europe. In other words, the UK and Dutch government support the renewable energy program for a long time. This support will help wind power occupies more important part of whole energy. However, some countries will not have enough money to support this program, and make wind power be …show more content…
In some countries, although turbines make the wind power be uninterrupted, the energy consumption keeps increasing during the whole wind energy exchange process. As Udo (2013) points out, almost 10% of the total energy generated in 20 years by a wind turbine is spent on the building and operation of the machine itself in the Europe. It means maintaining wind power working will cost some energy consumption. However, this energy consumption will be higher because of the flexibility of grids. Grids are the system for every country to transport electricity through different areas. The flexibility of grids will affect the efficiency of electricity
