Is biogas purification a renewable energy source? What are the problems faced by the development of post renewable energy?

可再生能源可以在自然界中回收它们包括太阳能、水电、风能、生物质能、波浪能、潮汐能、海洋温差能、地热能等。它是一种取之不尽、用之不竭的能源不需要人类的参与就可以自动再生它是相对于取之不尽、用之不竭的不可再生能源而言的一种能源。

Renewable energy can be recycled in nature, including solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy and so on. It is an inexhaustible and inexhaustible energy, which can be regenerated automatically without human participation. It is an energy relative to the inexhaustible and inexhaustible non renewable energy.

1、利用效率低

1. Low utilization efficiency

可再生能源系统消纳容量有待提高利用效率有待提高主要是由于以下原因：基于我国资源禀赋和负荷中心的逆向分布资源与负荷的匹配性相对较差在某些地区难以消纳；中国经济进入新常态电力需求放缓装机容量出现相对过剩；“三北”地区供电结构中调峰电源相对较少尤其是自备电厂供热机组比例较大冬季采暖期调峰能力进一步受限；辅助服务政策不到位或执行不力；可再生能源开发建设快配套电网规划建设相对滞后电力通道输送能力有待提高。

The consumption capacity of renewable energy system needs to be improved, and the utilization efficiency needs to be improved, mainly due to the following reasons: Based on the reverse distribution of China's resource endowment and load center, the matching between resources and load is relatively poor, which is difficult to be consumed in some areas; China's economy has entered the new normal, the power demand has slowed down, and the installed capacity is relatively surplus; In the "Three North" area, the peak load power supply in the power supply structure is relatively small. Auxiliary service policies are not in place or poorly implemented; The development and construction of renewable energy is fast, and the planning and construction of supporting power grids lags behind. The transmission capacity of power channels needs to be improved.

2、技术水平低成本高

2. Low technical level and high cost

技术水平有待提高成本应通过进一步的技术进步和产业升级来降低比如水电建设中的环保和移民问题增加了开发难度导致成本较高；

The technical level needs to be improved, and the cost should be reduced through further technological progress and industrial upgrading. For example, the problems of environmental protection and immigration in hydropower construction increase the difficulty of development, resulting in higher cost;

如何有效利用海上风电风力发电设备制造、微选址、海上风电设计和建设等核心技术推动；太阳能高效晶体硅、薄膜产业、无害化处理、火力发电一体化技术进一步提高转化率实现实惠上网；生物质天然气一体化、航空燃料和绿色生物炼制等关键技术和产业水平有待提高；海洋能和地热能的发展尚未达到成熟应用阶段。

How to effectively use the core technologies such as offshore wind power, wind power equipment manufacturing, micro site selection, offshore wind power design and construction; Solar energy efficient crystalline silicon, thin film industry, harmless treatment and thermal power generation integration technology to further improve the conversion rate and realize affordable access to the Internet; Key technologies and industrial levels such as biomass natural gas integration, aviation fuel and green bio refining need to be improved; The development of ocean energy and geothermal energy has not yet reached the mature application stage.

3、资金的补贴差距扩大

3. The subsidy gap of funds has widened

在可再生能源发展的初始阶段国家需要鼓励、支持和扶持政策。国家可再生能源发展基金来源单一很难征收额外的电价资金的补贴被推迟风电和光伏的一些发电企业存在资金周转困难和亏损等问题。

In the initial stage of renewable energy development, countries need to encourage, support and support policies. The source of the national renewable energy development fund is single, it is difficult to levy additional electricity price, the subsidy of funds is delayed, and some power generation enterprises of wind power and photovoltaic have problems such as capital turnover difficulties and losses.
