After the earthquake and tsunami, Japan is now fighting around the nuclear power plant in Fukushima. Many other plants are off and the electricity must be saved across the country in order to assist the distribution of electricity to the affected areas. The Tokyo area is already experiencing controlled “blackout” to help the network, but it is asked everyone to save energy. Setsuden, a collective of graphic designer through Twitter had the idea of ??producing a series of posters to encourage people to become aware of the problem.
