Useless waste and necessary waste　1.4 Law of energy conservation (1)

The law of energy conservation means that the total energy before and after a reaction does not change in a chemical reaction. But the law mentioned here is not this chemical law.

We have continued to consume energy through many activities such as life support, everyday life, work and travelling since we were born this world. It seems as if we were producing these energies. However it is that we are just using or borrowing part of a large natural life form called the earth.

We humans can now use energy that has been naturally lost or energy that could not be extracted as energy thanks to the development of science and technology. (Solar power generation, wind power generation technology and so on)

If we take the position that we are allowed to use energy or borrow energy, we must use energy carefully. If we can, we would like to establish a technology that can create energy. The meaning of the law of energy conservation here is to equalize (conserve) the energy used and the energy created. If this becomes possible, our descendants will also benefit from energy.

Creating energy on an individual level is never easy. It requires money and not all can do it. However anyone can save resources and energy.
