| 要旨 | The Kyoto Protocol, adopted in 1997 globally, accelerated the introduction of power generation by renewable energy to prevent greenhouse gas emission from 2000. Furthermore, there have been growing concerns about both safety and reliability of nuclear power generation since the Great East Japan Earthquake caused a number of nuclear accidents in March 2011. Many countries around the world are consequently showing a great interest in renewable energy. Wind power, as the most practical renewable energy, has been spreading all over the world since 2000. Today, the cost reduction in wind power generation is the biggest key to boost the prevalence of the wind power generation. Rotor blades of wind turbine generators installed onshore are being upsized to be able to operate in weaker wind blowing areas, while higher power generating offshore turbines are being developed. As a result, rolling bearings installed into these turbines should be larger and more reliable. |
