The main problem with renewables is:

1. The market maturity is low and the guarantee capacity is insufficient.

Although China has done a lot of work in establishing a renewable energy market, there are still many problems, mainly manifested in: insufficient understanding of the strategic, long-term and arduous nature of establishing and improving the renewable energy market; Due to the relatively high cost and the characteristics of the product, renewable energy still lacks a wide social recognition and a perfect market environment.

2. The policy system is not perfect, and the measures are not matched.

Although our country has enacted a renewable energy law.

The requirements for its institutional construction are also relatively comprehensive, but the policy measures and institutional construction are not matched, and they have not yet fully adapted to the requirements of renewable energy development.

The main reasons are: 1) the special plans or development roadmaps for the development of various renewable energy have not been issued in a timely manner, and a clear planning target guidance mechanism has not yet been formed;

2) Lack of market regulation.

mechanism, there is no clear provision on the responsibilities, powers and obligations of energy monopolies; There is also a lack of product quality testing and certification system;

3) Planning, project approval, and special funds for renewable energy.

lack of a unified coordination mechanism for arrangements, ** mechanisms, etc.;

4) lack of transparency in planning, policy formulation and project decision-making;

5) Lack of reporting, monitoring and self-improvement systems for the implementation of the law.

6) Lack of mechanisms and policies for the coordinated development of renewable energy and social and natural ecological environmental protection, especially hydropower and biomass energy.

It is also necessary to improve supporting policies for resettlement, land use and ecological protection.

3. Insufficient investment in technology research and development, and weak independent innovation ability.

In order to reduce costs as soon as possible and overcome the limitations of external support conditions such as power grids, it is necessary to rely on continuous technological innovation and industrial application. Although China has improved its R&D level and innovation ability in key technologies for renewable energy utilization, it is generally on par with developed countries abroad.

Compared to still significantly backward, the main manifestations are:

1) Basic research is weak, and innovative and basic research work is carried out less, started late, and has a low level, such as photovoltaic power generation technology.

Cellulose to ethanol.

and other technologies, lacking the technical base required for large-scale development;

2) Lack of a strong technical research support platform, which makes it difficult to support basic scientific and technological research and provide public technical services;

3) Lack of a clear and systematic technology development route and long-term development ideas, and no continuous and rolling R&D investment plan;

4) The financial support for R&D is obviously insufficient.

4. The industrial system is weak and the supporting capacity is not strong.

The rapid development of China's industry in recent years is based on the rapid investment of domestic and foreign funds. In terms of technology, China is still lagging behind the world's most advanced level, and its products lack competitiveness; In terms of key processes, equipment and raw materials, it is still heavily dependent on imports and subject to the monopoly of foreign technology, such as large-scale wind turbines.

Bearings, core production equipment for solar cells, and high-efficiency biological enzymes required for cellulosic ethanol.

Wait. Although these situations have been improved through recent efforts, from the perspective of long-term development of the industry, the weakness of the industrial system is still an important problem that plagues the development of the industry.

Non-renewable resources mainly include: coal, oil, natural gas, etc.

Non-renewable natural resources, or "non-renewable resources". Also known as "non-renewable natural resources", "non-renewable natural resources", "non-renewable resources". It refers to natural resources that cannot be regenerated for a long period of time after being developed and utilized by human beings.

It includes fossil fuels, metallic and non-metallic minerals in geological resources (the metallogenic period is often measured in millions of years), and soil resources in semi-geological resources. Such resources should be used sparingly and comprehensively as much as possible to avoid waste and destruction.

Characteristics of non-renewable resources

1. Non-renewable. Non-renewable resources are formed very slowly compared to the development of human society, and compared with other resources, the rate of regeneration is very slow, or almost non-renewable.

2. The irreversibility of the consumption of non-renewable resources. Coal and oil are the remains of paleontology that have been buried deep underground and formed over a long period of evolution, and once burned and consumed, it is impossible to regenerate in hundreds or even tens of thousands of years.

Huge development potential, clean and pollution-free, most of them can be used in an environment, low development cost New energy in China currently refers to renewable energy and nuclear energy, I think it should be mentioned as follows: Compared with conventional energy, renewable energy has the following advantages: 1. The resources of renewable energy are greater than those of conventional energy, and conventional energy is average.

It generally refers to the energy resources that cannot be regenerated at this stage after human development and utilization.

For example, coal and oil are the remains of paleontology that are buried in the deep underground, formed after a long evolution, and once burned and consumed, it is impossible to regenerate in hundreds or even tens of thousands of years, so it belongs to "non-renewable energy".

Human beings will only consume non-renewable resources, and it is impossible to maintain their original reserves or regenerate. Among them, some resources can be reused, such as gold, silver, copper, iron, lead, zinc and other metal resources, and others are non-reusable resources, such as coal, oil, natural gas and other fossil fuels, when they are used as energy and burned, although the energy can be converted from one form to another, but as the original material form has ceased to exist, its form has changed.

Energy sources that are not renewable resources include anthracite, lignite, **, natural gas, oil shale, chemical energy, peat, nuclear energy, gasoline, diesel, etc.

Energy that is not a renewable resource is fossil energy. Fossil energy refers to fossil fuels that exist on Earth, such as coal, oil, and natural gas. They are widely used in fields such as power generation, processing, transportation, and heating.

The abnormal use of fossil energy sources has led to the release of large amounts of carbon dioxide into the atmosphere, which is one of the main causes of global warming.

Renewable resources refer to resources that can be reused in nature, such as solar, wind, hydro, geothermal, and biomass. These resources have a quick regeneration period to meet the world's growing energy demand and reduce environmental concerns. Renewable resources have significant advantages over fossil fuels in terms of environmental protection, economy and sustainability.

The use of renewable resources produces less pollution and emissions, and will not be exhausted, and is expected to become the dominant energy source in the future and promote the global green energy transition. The use of fossil energy brings serious environmental problems and climate change.

Burning fossil fuels will release a large amount of greenhouse gases, leading to global warming, sea level rise and other problems, and will cause a variety of pollution such as air pollution, water pollution and soil pollution, which poses a huge threat to health and ecosystem failure.

Fossil fuels are inseparable from people because of their convenience and high energy, but they also have disastrous consequences for the environment. Therefore, we need to accelerate the development, utilization and application of renewable energy, develop new energy technologies, reduce dependence on fossil energy, and achieve green, low-carbon and circular development.

Expand your knowledge:

Renewable resources are natural resources that can maintain or increase their reserves at a certain rate of growth through natural forces. For renewable resources, it is mainly through the reasonable regulation of resource utilization rate to achieve the pure and sustainable utilization of resources.

The sustainable use of renewable resources is mainly constrained by the law of natural growth. Renewable resources from animals and plants in nature, crops, forests, seafood processing waste, etc., collectively known as biomass, are inexhaustible resources.

1. Non-renewable energy sources include: coal, natural gas, oil shale, and nuclear energy.

2. Renewable energy includes: solar hand rolling, hydropower, wind power, biomass energy, wave energy, tidal energy, and ocean temperature difference energy.

3. Renewable energy: energy that can be continuously regenerated in nature and regularly replenished.

4. Non-renewable energy: energy that has been formed over hundreds of millions of years and cannot be restored in a short period of time.

Non-renewable energy sources are the earth's stored resources such as coal, oil, natural gas, 、、、etc., which, once used, can no longer be generated. (These deposits were formed over a long period of time over hundreds of millions of years.)

Renewable energy is energy that can be used for a long time, such as wind, hydro, 、、、and solar energy, and is characterized by the fact that it can be used again and again, and is called renewable energy.

The common feature of these energy sources is that they may be converted into energy needed by people in production and life, such as electricity, heat, chemical energy, 、、、 for people to use.
