According to a survey by Professor Hidefumi Kurasaka of the Graduate School of Social Sciences, Chiba University, and the NPO Institute for Environmental Energy Policy, the growth rate of domestic wind power generation and geothermal power generation, which started operation in 2019, exceeded that of solar power generation. It became clear in. After the introduction of the feed-in tariff (FIT) in 2012, the explosive increase in the introduction of solar power generation called the solar bubble has continued, but this is the first time that wind power generation and geothermal power generation have exceeded this.
According to Chiba University, the total amount of wind power generation introduced in 2019 is 76.4 petajoules. It increased by 2018% from 68.0 petajoules in 12.2.Geothermal power generation is 23.0 petajoules, up 2018% from 20.3 petajoules in 13.3.
On the other hand, photovoltaic power generation was 676.8 petajoules, an increase of only 2018% from 637.7 petajoules in 6.1, and the growth rate was lower than wind power and geothermal power generation for the first time since the introduction of FIT.
After the introduction of FIT, the period from the introduction of FIT to the start of operation was short, and the interest of power generation companies was concentrated on solar power generation that can be easily installed, and the total amount of power generation and the growth rate of each year were far behind other renewable energy.However, the fixed price purchase amount of solar power generation is declining every year, the number of places that can be easily installed and is not opposed by local governments and residents is decreasing, and large-scale projects that take time to start operation It seems that the reversal was caused by the fact that power generation companies began to pay attention to wind power and geothermal power generation.
However, looking at the percentage of the amount of electricity generated, solar power generation accounts for 65.3% of the total.Although plans for offshore wind power have begun to move around the country, solar power is likely to play a leading role in renewable energy for some time.
