World's First 1-Gigawatt Wind Farm!Ever since the Fukushima nuclear disaster, Japan has been looking for new sources of energy to replace its nuclear reactors. This is no easy task, not only because nuclear power provided a significant fraction of the country's electricity, but also because if you just replace nuclear by fossil fuel power plants, you are trading one problem for another. Clean energy is the ideal substitute despite many challenges, but Japan is forging ahead!
Officials have unveiled plans to build the largest wind farm in the world. It will be built 10 miles off the coast of Fukushima, a location with heavy symbolism.
Currently, the largest wind farm in the world is off the coast of Suffolk in the U.K. Called the Greater Gabbard farm, it produces 504 megawatts of power using 140 turbines. The new farm planned for Japan is expected to produce 1 gigawatt using just 143 turbines.
Instead of anchoring each turbine directly to the ocean floor, the plan is to mount them on floating steel frames that will be anchored to the continental shelf below. To keep them upright, ballast will be used underneath. The plans also call for using 2 megawatt turbines, each standing 200 meters high. The site was chosen due to the existing infrastructure that had been used to transport power from the Daiichi plant before its destruction." (source)
The prefecture of Fukushima has set for itself the goal of being 100% energy self-sufficient by 2040, and this gigantic wind farm is only one of many pieces of the puzzle. They're also working on plans for the biggest solar farm in Japan. Not bad!
