  • Offshore Wind Power Promises to Boost Fukushima RecoveryIn November 2013, a 2,000-kilowatt wind turbine off the coast of Fukushima Prefecture began trial operations. Two more turbines of 7,000 kilowatts each will be installed this year, creating the world’s largest floating offshore wind farm. The project is an important part of the prefecture’s effort to revive its economy following the March 11, 2011, earthquake and tsunami.
  • Hopeful Signs: Renewable Energy from Geothermal and Solar PowerIn the wake of 3/11, people are looking increasingly to renewables to provide their electricity. While solar power had been popular even before the disaster, geothermal energy has not reached even a small fraction of its potential. We examine the reasons for this development gap.
  • Building a Floating Wind Farm Off the Fukushima CoastAfter being devastated by the Tōhoku earthquake and nuclear disaster last March, Fukushima Prefecture is now looking to renewable energy as a new area of industrial development. Tests of the world’s first large-scale offshore floating wind farm are underway, and hopes are high.
  • Rice Paddy Power: Harnessing Microbial EnergyEnergy harvesting transforms the latent energy of the natural world that flows through our everyday environment into power we can use. In the fields that produce Japan’s staple crop, rice, work to harvest this energy has already begun.
  • The Promise of Kinetic Power GenerationTechnology to collect energy from our everyday world is gaining attention. “Energy harvesting” technology can turn a crowded floor or a remote control into a tool for producing power. The technology holds a wealth of possibilities.
