How do you increase your solar energy output when you need all your land for agriculture and for housing? Answer: take to the water. That’s just what they are doing in Japan. The world’s first floating solar plant was built in Japan, in Aichi Prefecture in central Honshu. The country’s many inland lakes and reservoirs are now home to 73 of the world’s 100 largest floating solar plants and account for half of those plants’ 246 megawatts of solar capacity. Hyogo Prefecture in southern Honshu has almost 40,000 lakes and already hosts nearly half the floating solar capacity of the world’s 100 largest plants. Many plants are small scale, helping the region to kick-start the move to distributed local power generation which the World Economic Forum has identified as the key to transforming the world’s power supply.
