Think about energy

In the previous pages, we have summarized the so-called large-scale power generation.

Whether it is conventional power generation methods such as thermal power or nuclear power, or power generation using renewable energy, it is indispensable for the production of electric power necessary for our daily lives.

But did you know that there are significant risks associated with these power generation methods?


As mentioned in the introduction, it has been pointed out that the sediment-related disaster that occurred in Atami in July 2021 may have been caused by forest development and embankment for the development of solar power generation.

In other words, by cultivating nature and performing solar power and wind power generation on a large scale in one place, not only will it be destroyed by nature, but it may also lead to a major accident. There is.

In addition, while transmitting electricity from a power plant to a home, some electric energy is lost as heat and vibration due to the resistance of substations and transmission and distribution lines, so-called transmission loss problem and electricity production. In recent years, it has been pointed out that there is a danger in the event of a disaster in the area due to the concentration of places to do it.

We wondered if there was a solution to avoid such a risk.
Then we learned about energy harvesting.

Energy harvesting is a technology that "harvests" various forms of low-density energy, such as heat and vibration around us, and converts it into electrical energy.
It is a relatively old technology, for example, wristwatches and calculators that charge with sunlight are already widespread as products that utilize energy harvesting technology.

Our future will be better by investigating existing power generation technologies that utilize the energy harvesting, sharing ideas that can be converted into energy in our lives, and making power generation feel closer to us. I thought it would be.


This energy is used to solve the risk of destroying nature by increasing the number of existing large-scale power plants, which causes great damage to the living area, and the problem of energy loss due to power transmission from a distance. I would like to consider how to use energy with the aim of "local production for local consumption of energy" by utilizing harvesting.

By doing so, I think that a clean future of "coexistence of energy and nature" will come.
