Definition of Agricultural Renewable Energy

For the purposes of this chapter, agricultural renewable energy combines the concepts of "agriculture" and "renewable energy." According to the Dictionary of Agriculture, "agriculture" is a human productive activity combining "natural reproduction" and "economic reproduction" for the purpose of obtaining the material goods needed for living and production, through the production of products involving plants, animals, and microorganisms, taking living animals and plants as the main objects of labor, and arable lands as the basic means of such production.1

According to the Huaxia Concise Encyclopedia, "renewable energy" is "recycled energy that has the ability of natural self-recovery in the ecological system and will not be lessened gradually through natural processes or human utilization including solar energy, hydro energy, wind energy, biological energy, tidal energy, wave power and geothermal energy etc."2

The concept of "biomass energy," in the context of "renewable energy," is defined in the Encyclopedia of China (Agriculture Volume) and the Encyclopedia of China (Succinct Edition) as energy generated from firewood, straw, carbohydrate-bearing

crops, oil crops, hydrophytes, farming wastes, and animal excrement formed through direct burning, or after being processed into gaseous, liquid, or solid fuel.3 On the basis of these established definitions, the following characteristics can be identified for the purposes of defining and understanding the concepts of agriculture, renewable energy, and biomass energy:

1. agriculture is a human productive activity combining "natural reproduction" and "economic reproduction";

2. products generated or obtained from the act of agricultural production are biological products;

3. biological products obtained from agricultural production are used as the basis of human economic production and people's livelihoods;

4. renewable energy regenerates itself and so can be reused;

5. renewable energy will not exhaust itself through natural processes or human utilization;

6. biomass energy is a type of renewable energy;

7. biomass energy refers to biomass that can be directly or indirectly used as fuel; and

8. biomass energy mainly refers to wastes and processed products of wastes generated during the production and processing of agricultural, forest, and livestock products.

In this context, "agricultural renewable energy" can be defined as energy produced from biological substances, such as crop straw, firewood, agricultural wastes, or animal excrement, that are generated or obtained during agricultural production, such as planting, breeding, and reaping, which can be used as fuel directly or after processing. The focus of this chapter is on the integrated utilization and management of "agricultural wastes" and "subsidiary agricultural products" in agricultural biological substances. Therefore, "carbohydrate-bearing crops" and "oil crops," as defined in the Encyclopedia of China (Succinct Edition) are not included within the scope of this chapter.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
