将下列段落翻译 To explain what biomass energy is, first we need to understand what biomass is. Many people think that the term "biomass energy" is something new. However it’s one of the oldest forms of energy in the world. It’s also one of the greenest, cheapest and easiest to extract energy. Biomass is the organic matter found in crops, trees and other plant materials. It derives energy from the photosynthesis process from the solar energy that plants use to create sugars, carbohydrates and starches. Biomass is the world’s oldest solar battery. The amount of sunlight that reaches the earth’s surface during one hour is sufficient to power the entire world for a year. But how do we collect the energy? Sunlight disperses everywhere and shines all over the whole globe, which make the energy very difficult to collect in a concentrated amount. Biomass energy is not only a green technology, but also a renewable energy source that can replace coal quickly and cost-effectively, providing the same operational benefits while dramatically improving the environmental profile of energy generation. The biomass is all over the world its storage capacity is huge. Every year the production of plants on the earth is equivalent to 20 times the current human consumption of fossil energy, or equivalent to 160 times the world’s existing population of food energy. Biomass energy is an important source of geothermal energy, which provides a basic energy source for the living and life of mankind since ancient times. Biomass is healthy forests. Forests are our greatest allies in keeping our planet’s ecosystems in balance because they take in CO 2 during photosynthesis, greatly reducing greenhouse gases and creating an equilibrium between the carbon sinks, which include the atmosphere, vegetation, soil oceans and, marine life. Biomass energy is great, but at present, human beings are taking advantage of 1% of its total amount. In order to complete the natural carbon cycle, the vast majority of the natural decomposition of the energy and carbon elements is released to nature.
