# Global Expansion of Japan’s Wind Power Generation

Among all renewable energy fields, wind power generation is expected to have the largest increase in electricity output by 2035, which the IEA estimates at 2,632 TWh. The estimation also says the ratio of wind power among all power generation will increase from 1% in 2008 to 8% by 2035, and that wind power generation can be considered a promising field.

Japan’s wind power generation technologies are steadily implemented around the world. A certain Japanese private-sector producer of wind power turbines received a large order of forty-nine 1,000kW wind power turbines from a generation businesses in the United States in March 2011.

This Japanese private/commercial management used ingenuity in designing the length and shape of the blades to develop wind power turbines that efficiently generate power even where it is not very

### C. Global Expansion of Transportation and Transport Systems

Japan’s outstanding technologies for transportation and transport systems are also being implemented in other countries.

The shinkansen (bullet train) and its technology have been transferred to other countries such as Taiwan and the UK. Taiwan's High-Speed Rail (THSR, Taiwan's shinkansen) line runs 345 kilometers from Taipei (Nangang Station) to Gaoxiong (Gaoxiong Station). The THSR 700T series is a variant of the 700 Series Shinkansen, operating with a top speed of 300 km/h (Photograph 4-3-4). In the UK, the first high speed railway was built and is operating with trains designed using Japan's shinkansen technologies.

windy, and those technologies are highly valued in other countries. The company is preparing for mass-production of large windmills, with the offshore wind power generation in view for the future.

Compared with France’s TGV and Germany’s ICE in regard to environmental performances, the shinkansen train has a wider body and greater interior space, while the body weight is lighter, less than half that of the TGV or the ICE in terms of passenger capacity by about one body (Figure 4-3-23). In addition, because of its light weight, it has achieved environmental performance breakthroughs, such as greater fuel-efficiency, lower frictional wear of rails, and more airtight walls, which means it is possible to keep the tunnel cross-sections small, comparatively minimize infrastructure construction and use of land, and reduce consumption of resources.

Various technologies are utilized for energy efficiency during its operation. The latest N700 series (which debuted in 2007) adopted a nose shape that has outstanding aerodynamic characteristics (Figure 4-3-5) and a uniform flat structure that has no protrusions or indentations between the train's external panels and the window glass. It also reduces resistance when running by installation of all-circumference hoods between all cars and making the surface of the train as flat and smooth as possible. Moreover, it adopts a body-tilting system in order to improve speed around curves, and has expanded the use of electric regenerating brakes.

It is expected that by popularizing shinkansen technology with its outstanding environmental capabilities, expanding
