What are the potential of geothermal energy as a geothermal power generation business?

Currently, Japan has 111 active volcanoes in Japan. The lack of fossil fuels (coal, oil, etc.) is the same as in the past. Import more than 80% of energy resources. As a small energy resource country, it is a well-known fact that Japan has used military force before and during the war in search of energy resources overseas. The government formulated the Basic Energy Plan in 2011 and has formulated policies to raise the rate of receiving pure domestic renewable energy such as solar, wind and geothermal power generation. The Energy White Paper released in June 2020 contains 2.347 million kilowatts of geothermal resources in Japan, the third largest in the world. (By the way, U.S. 1st place, Indonesia 2nd place)

However, Japan's geothermal power plant capacity is 540,000 kilowatts, which is the 10th largest in the world. While having a rich amount of resources, the capacity of power generation facilities is extremely small. Recently, the capacity of power generation facilities has been removed in the Philippines, Kenya, New Zealand, etc., which have few resources. I don't know why.

In order to realize a high power generation capacity, it is only to lower the power generation capacity. In other words, if the power generator is in Japan, it is too expensive. Renewable energy using local resources is one of the projects related to regional economic revitalization projects, whether it is geothermal or biomass. In addition to fuel generation, there are not a few cases where power generation is required. Aling it is a matter of course, even in the gasification and energy business of manure discharged by pig farmers in a certain area, the maximum neck has a bitter experience that was frustrated because the price of power generation equipment is high.

I have experience.

It is possible to make a business plan easily until it becomes fuel, but when power generation is required, it is always on the rocks. In a word, the power generator does not go to the power generation at a high unit price. That's why renewable energy, especially biomass-related businesses, is not widespread in many places.

Most of the power generation equipment used in geothermal power generation overseas is made in Japan, but it is not used in Japan. High-priced neglect of power generation equipment manufacturers, nuclear power plants, fossil fuels, etc.

It seem that the energy policy of this country is involved. Based on equipment utilization, solar power is 13%, on-land wind is 20%, offshore wind is 30%, and geothermal power generation is more than 80%.
