What does green energy mean?
Organisms include plants, animals and microorganisms. Animals and most microorganisms feed on plants. Except for a few microorganisms, only green plants are the real "builders" on the earth. Green plants use simple inorganic substances such as carbon dioxide and water as raw materials to synthesize various complex organic substances, which not only meet their own needs, but also are enjoyed by other organisms. This process can only be carried out under the condition of light, which is called photosynthesis. The process of photosynthesis of green plants is not only the process of their growth, but also the process of their absorbing and storing solar energy. In other words, biomass energy, like fossil energy such as coal, oil and natural gas, is derived from solar energy and is a form of solar energy. The difference is that the energy in fossil fuels is solar energy stored by biomass hundreds of millions of years ago, while biomass energy is solar energy fixed by contemporary plants through photosynthesis. These energies exist in plants in the form of glucose and starch, and can be converted into fuels such as methanol, ethanol, methane and hydrogen after biotechnology treatment. These biofuels are called "green energy" because they do not contain sulfur and other impurities, and will not produce harmful gases such as SO2 and CO2 when burned.
