What are chemical energy and biological energy?

Bio-energy is a form of energy in which solar energy is stored in organisms in the form of chemical energy. It is a kind of energy with biomass as the carrier, which directly or indirectly comes from photosynthesis of plants. Among all kinds of renewable energy, biomass is unique. It is the stored solar energy and the only renewable carbon source, which can be converted into conventional solid, liquid and gas fuels. It is estimated that the annual fixed carbon in photosynthesis of plants on the earth is 2x 101t, and the energy content is 3x 102 1J, so the solar energy stored in branches, stems and leaves by plants through photosynthesis is equivalent to/kloc-of the global annual energy consumption. Bioenergy is the fourth largest energy source.

All chemical reactions are essentially changes in the motion state of the outermost electrons of atoms; The energy absorbed or released in chemical reaction is called chemical energy, and the source of chemical energy is the result of the change of the outermost electron motion state and the change of atomic energy level in chemical reaction.

Atoms are bound through nuclei, electrons are bound through electromagnetic fields, molecules are bound through atoms through electromagnetic fields (chemical bond energy), and objects (solid, liquid, gas, abiotic and biological) are bound through molecules through electromagnetic fields (intermolecular forces). In the space of these material structures, there is an electromagnetic field substance-now called Xunzi, and in Yi ology called Taiji and Chongqi, which is an empty thing. Chemical bond is a substance, a form of substance, and chemical bond is an electromagnetic field substance. Chemical reaction is a process in which atoms recombine into new substances. In the process of chemical reaction, the bond energy level of chemical bond changes, so the phenomenon of chemical energy appears. When the bond energy (ion energy level and electromagnetic field energy level) increases, it is an energy absorption reaction, and when the bond energy decreases, it is an energy release reaction. Bond energy substance is electromagnetic field substance-ion, and the energy phenomenon produced by chemical reaction is a material phenomenon formed by electromagnetic field substance-ion-flow. This is the material explanation of chemical reaction and chemical energy.
