The other day, we completed the installation of V2H at our house. It will be installed following the purchase of a solar power system 11 years ago and an electric vehicle three years ago. I like new things and takes pride in being a naturalist, so I have been making this type of investment. In addition, the installation, including the heat insulation sash and the electric compost, was done while watching the timing of subsidies from the national and local governments. I have not accurately grasped the investment efficiency, but the expected amortization of solar power is 7 years, which is considered to be a success in 9 years. Electric vehicles and V2H are unknown at this time. I don't care much about financial efficiency because my motives are experience and pleasure rather than investment. That said, I don't end up throwing money down the drain, and even if it doesn't pay off, it's valuable to be able to think about the future and gain knowledge about new technologies. It is also a big benefit that I feel proud as a person that I am contributing to the earth and society steadily athough it is not conspicuous, such as the contribution to the reduction of fossil energy consumption, the contribution to the exhaust gas and noise obtained by electric vehicles, etc.
Even so, there are many negative opinions about renewable energy and electric vehicles. While criticism of short-sighted investment effects is within the scope of my understanding, there is something wrong with using the disposal of solar panels, concerns about Chinese products, and electric vehicle charging infrastructure issues as points of contention. The problem of decommissioning nuclear reactors is much more troublesome than the disposal of solar panels. Concerns about Chinese products are outdated, and if you are paticking on made in Japan, setting up a factory in Japan and producing them in Japan will also be an economic measure. Electric vehicle charging infrastructure problems can be solved easily and cheaply in a much shorter period of time than linear Shinkansen or deep tunnels. Since the economic effect is also realized at an early stage, the certainty of investment risk prediction is high.
Even so, the chorus of criticism is not about technology, but by legacy industries such as gasoline-powered automobiles, national policy industries represented by heavy electrical machinery, and concession industries such as civil engineering and construction. It must be the work of the gang.
As a Japanese citizen, I am ashamed that the lessons of the lost 30 years have not been utilized at all.
