Marine national Japan's Renewable Energy - Practical applications of offshore wind power generation -

The energy portfolio of Japan is heavily depending on imported fossil fuels including LNG, oil and coal. Share of these fossil energy sources leach to 95%. Self-sufficiency rate of energy of Japan is 4.8% including 1.4% of renewable energy in the year of 2010.

Japan is surrounded by sea and we are the 6^th largest country in the world in terms of sea surface area. Energy production at sea by wind, wave, and tide has great potential for the improvement of self-sufficiency rate.

Because of reason above, energy production at sea is demanded by the society, however, this attempt is a novel challenge for energy-related industries.

This feature article provides vision for civil engineers from the viewpoint of various fields including finance, planning, environmental assessment, planning and construction. Role and responsibility of civil engineering in the renewable energy industry will be proposed.
