As for biogas, a new and clean energy, its application prospect is very broad in the future because of its outstanding characteristics of high energy, energy saving, safety and environmental protection. In China, the technology and equipment of biogas production, collection, storage and utilization are becoming more and more mature, so why more and more people choose biogas generator set? This is inseparable from its own characteristics.

1、可再生，污染少。用沼气进行发电，不用担心会有枯竭的。据统计，至2002年底世界剩余石油探明储量为1407.04亿吨。根据世界已探明的化石能源储量推算，石油还可使用40~50年，天然气还可使用60~70年，煤炭则能维持225年左右。可见，说明化石能源离我们而去的日子已不远。而以沼气为代表的生物质能源的寿命几乎是无限的，只要太阳存在，沼气也将存在。

1. Renewable, less pollution. Using biogas to generate electricity, there is no need to worry that it will be exhausted one day. According to statistics, by the end of 2002, the world's remaining proven oil reserves were 140.704 billion tons. According to the proven fossil energy reserves in the world, oil can be used for another 40-50 years, natural gas for another 60-70 years, and coal for about 225 years. It can be seen that fossil energy is not far away from us. The life of biomass energy represented by biogas is almost unlimited. As long as the sun exists, biogas will also exist.

2、原料来源广泛。沼气发电机组的主要燃烧成分是甲烷，由甲烷产生菌厌氧消化有机物产生。所以只要有机物存在的地方，再配以适合的环境条件，就会有甲烷的生成。例如人畜的粪便、有机工业废水、垃圾填埋场、农作物秸秆等都可用做沼气产生的原材料。今后随着畜禽养殖业和工业企业的发展，沼气的生产量还会增加。以一个60万人口的城镇为例，每天产生垃圾约600吨，产生沼气1万立方左右，可以供1000千瓦的燃气发电机组进行发电。且城市越大，垃圾中含的有机物越多，产生的沼气量也就越多。我国人口众多，适合做这样项目的垃圾填埋场也很多。因此，沼气的来源十分广泛。

2. The sources of raw materials are wide. The main combustion component of biogas generator set is methane, which is produced by anaerobic digestion of organic matter by methane producing bacteria. So as long as the organic matter exists in the place, coupled with suitable environmental conditions, there will be methane generation. For example, human and animal manure, organic industrial wastewater, landfill, crop straw and so on can be used as raw materials for biogas production. In the future, with the development of animal husbandry and industrial enterprises, the production of biogas will increase. Take a town with a population of 600000 as an example, it produces about 600 tons of garbage and about 10000 cubic meters of biogas every day, which can be used by 1000 kW gas-fired generating units for power generation. And the larger the city is, the more organic matter is contained in the garbage, and the more biogas is produced. China has a large population, so there are many landfills suitable for such projects. Therefore, the source of biogas is very extensive.

3、受环境限制小。沼气发电机组的规模比较小，对场地的要求不高，只要有沼气产生的地方基本上都可以进行发电。不像水电必须建立在水力资源丰富的地方，而且还要考虑电站对周围生态环境的影响；太阳能发电要建在日照时间长且比较偏僻的地方，因为太阳能发电要占用大量的土地，必须考虑项目的经济性.

3. Limited by the environment. The scale of biogas generating unit is relatively small, and the requirements for the site are not high. As long as there is biogas generating place, it can basically generate electricity. Unlike hydropower, which must be built in a place rich in water resources, but also consider the impact of the power station on the surrounding ecological environment; Solar power generation should be built in remote places with long sunshine time, because solar power generation takes up a lot of land, so the economy of the project must be considered
