What Are the Different Renewable Energy Advantages?

New energy (NE): Also known as unconventional energy. Refers to all forms of energy other than traditional energy. Refers to energy sources that are just beginning to be developed or are being actively researched, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy.

in 1980(

According to analysis, China's energy consumption structure has not changed significantly since 2001. Petrochemical energy, especially coal consumption, has always dominated primary energy consumption, accounting for over 90% and 60% of the total, respectively.

For the new energy industry, this is considered to provide the gospel. A comprehensive observation of China's stock market industry also illustrates this point. China's green energy stock prices have soared, and more idle funds have been invested in new energy and environmental protection industries. At the same time, China will surpass Europe as the world's largest market for alternative energy growth. Against this background, the new energy industry should seize this opportunity to actively develop wind power, solar energy, etc., and increase the proportion of new energy.

It is estimated that every year

1) Abundant resources, generally with renewable characteristics, which can be used by humans for sustainable use; for example, on land estimates that wind resources that can be developed and used are 253GW, and as of 2003, only 0.57GW was developed and used. It will reach 4GW, and it will reach 20GW by 2020, and the amount of solar photovoltaic grid-connected and off-grid applications is expected to increase from 0.03GW by 1-2 GW by 2020.

2) Low energy density, which requires more space for development and utilization;

3) No carbon or little carbon content, little impact on the environment;

4) Wide distribution, conducive to small-scale decentralized utilization;

5) Intermittent supply, with large fluctuations, is not conducive to continuous energy supply;

6) Except for hydropower, the development and utilization cost of renewable energy is higher than fossil energy.

Solar energy generally refers to the radiant energy of sunlight. The main forms of solar energy are three main ways: solar light-to-heat conversion, photoelectric conversion, and photochemical conversion. In the broad sense, solar energy is the source of many energy sources on the earth, such as wind energy, chemical energy, and potential energy of water. The main methods of using solar energy are: solar cells, which convert the energy contained in sunlight into electrical energy through photoelectric conversion; solar water heaters, which use solar heat to heat water, and use hot water to generate electricity. Solar energy is clean and environmentally friendly, without any pollution, high utilization value, and solar energy has no shortage of energy. Its various advantages determine its irreplaceable position in energy replacement.

The internal heat source of the earth can come from the energy released by gravity differentiation, tidal friction, chemical reactions and the decay of radioactive elements.

If there are two kinds of salt solutions, the concentration of salt in one solution is high, and the concentration of one solution is low, then after putting the two solutions together and isolating them with an osmotic membrane, osmotic pressure will be generated, and water will be removed from the low concentration solution. The solution flows to a highly concentrated solution. Fresh water flows in rivers, while salt water exists in the ocean, and there is a certain concentration difference between the two. in

Water energy is a kind of renewable energy and clean energy. It refers to energy resources such as kinetic energy, potential energy and pressure energy of water bodies. Broadly defined hydropower resources include

Some renewable energy utilization technologies have made considerable progress and have formed a certain scale around the world. Biomass energy, solar energy, wind energy, and hydropower, geothermal energy and other utilization technologies have been applied.

The International Energy Agency (IEA) conducted a study of international power demand from 2000 to 2030, and research has shown that the average annual growth rate of total power generation from renewable energy sources will be the fastest. IEA research believes that non-hydraulic renewable energy power generation will grow faster than power generation from any other fuel in the next 30 years, with an annual growth rate of nearly 6%, and its total power generation will increase five times between 2000 and 2030. By 2030, it will provide 4.4% of the world's total electricity, of which biomass energy will account for 80% of it. For details, please refer to the "Forecast of China's New Energy Industry Development Prospect and Investment Strategic Planning Analysis Report".

On March 16, 2015, 23 ministries and commissions including the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Science and Technology held inter-ministerial joint meetings for the development of strategic emerging industries. Seven major industries including energy-saving and environmental protection industry, new-generation information technology industry, bio-industry, high-end equipment manufacturing industry, new energy industry, new materials industry, and new energy automobile industry have become strategic emerging industries that China has focused on cultivating.

According to the conference information, among the 18 key industries in the emerging industries sector in 2014, the main business income of enterprises above designated size reached 15.9 trillion yuan, and the total profit reached nearly 1.2 trillion yuan, a year-on-year increase of 13.5% and 17.6% respectively. In the same period of 2013, the main business income of industrial enterprises above designated size increased by only 3.3%, and the profit increased by 1.6%, which was significantly lower than that of emerging industries.

Among the industrial enterprises above the designated size, the total profits of strategic emerging industries accounted for nearly 19%, and the main business income accounted for nearly 15%. The "Twelfth Five-Year" National Strategic Emerging Industry Development Plan proposes that by 2020, the value-added of strategic emerging industries will account for about 15% of the GDP. ^[1]

Sino-British Nuclear Energy Cooperation

Britain's nuclear energy development ranks among the world's leading levels, and it is an ideal partner for nuclear energy companies seeking business and technical cooperation. The British nuclear energy industry has a huge consumer market, and its development has also received strong support from government agencies and policies. At the same time, the British nuclear energy industry also has world-leading technical experience and talent base; not only that, the British nuclear energy industry The chain and complete supporting service system have also created a stable and healthy environment for the development of the industry.

In the UK s 2008 Climate Change Act, a long-term goal was set for energy development: By 2050, Britain s greenhouse gas emissions need to be reduced by 80% from 1990 levels. To achieve this goal, the United Kingdom is undertaking a huge energy restructuring plan, which is to decommission traditional power plants and start new energy generation projects including nuclear power. A project alliance of the British Energy Research Partnership (ERP), the National Nuclear Laboratory (NNL), the Engineering and Natural Research Council (EPSRC), the Nuclear Decommissioning Authority (NDA), and the Energy Technology Institute (ETI) has released the " Roadmap for Nuclear Fission Technology in the UK: Preliminary Report. The report pointed out that the United Kingdom must formulate a clear and specific long-term and long-term development strategy and roadmap for the nuclear energy industry, while assuming that if the United Kingdom has a safe, low-carbon energy structure by 2050, nuclear power will play a greater role.

On October 21, 2013, London time, the British government officially approved the plans of China National Nuclear Corporation and China National Nuclear Corporation to participate in the investment in new local nuclear power plants, which marked that Chinese nuclear power enterprises finally landed in developed western countries. Earlier, the Chinese and British governments signed the "Memorandum of Understanding on Strengthening Cooperation in Civil Nuclear Energy" after the Fifth China-UK Economic and Financial Dialogue (EFD) held in Beijing on October 15. Lord Minister of the Treasury, Lord Deighton, participated in the signing of the memorandum as a representative of the British side, which paved the way for the British government to officially approve the participation of Chinese nuclear power companies in the construction of Cape C.

Britain is the country with the longest history of civil nuclear power, and China is the country with the fastest development of civil nuclear power. This cooperation will benefit both China and Britain. China has the world's largest nuclear power equipment manufacturing capability and the world's most abundant capital, which is also a major driving force for Chinese nuclear power companies to go overseas.

Sino-Russian Energy Cooperation

Russia is a major energy resource rich country in the world. Its natural gas reserves and exports, oil production and exports, and coal, uranium, iron, aluminum and other resource reserves rank among the top in the world. As China's largest neighbor, Russia and China have mature and strong political relations. They regard China as a major partner and have the willingness and ability to cooperate with China in energy. They also have natural geographical advantages and complementary characteristics. It is China's energy security and sustainability. Develop valuable partners.

With the rapid development of Sino-Russian relations, the scale of energy cooperation between the two countries has gradually increased from small to large, from pure trade to oil, gas, nuclear, coal, electricity,

China's future new energy development strategy can be divided into three development stages: the first stage to 2010, the commercialization of some new energy technologies. In the second stage, by 2020, a large number of new energy technologies will reach commercialization level, and new energy accounts for more than 18% of the total primary energy. The third stage is to fully realize the commercialization of new energy sources and replace fossil fuels on a large scale, reaching more than 30% of total energy consumption by 2050.

As one of China's strategic emerging industries that accelerates its cultivation and development, new energy will provide solid technical support and industrial foundation for large-scale development and utilization of new energy. ^[3]

Old energy, new efficiency, no heat engine, new path: Soros investment (speculation) another solution of new energy

Engine new energy

Hydrogen energy, wind energy, solar energy, ocean energy, biomass energy, and nuclear fusion energy ... The way of new energy is just one step forward in multiple steps of energy utilization. And neglected, the engine with great potential or the innovation of work principle and concept is even more

The development of modern renewable energy technology is extremely rapid, and it will surpass natural gas shortly after 2010, becoming the second largest electric fuel after coal.

Environmental significance and energy security

The sharp increase in China's energy demand has broken China's long-term self-sufficient energy supply structure. Since 1993, China has become a net oil importer, and the amount of oil imports has increased year by year, making China access to the world's energy market competition. Due to the relative insufficiency of China's fossil energy production, especially oil and natural gas production, China's energy supply will become increasingly dependent on the international market in the future.

There are many uncertain factors in international trade. International energy prices may stabilize with the improvement of the international peaceful environment, but they may also fluctuate with the turbulence of the international situation. In the future, the instability of the international oil market and fluctuations in oil prices will severely affect China's oil supply and cause a great impact on the economy and society. Develop

On October 22, 2014, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection, the Ministry of Housing and Urban-Rural Development, the Ministry of Science and Technology, and the National Energy Administration jointly issued the "Working Plan for the Promotion of New Energy Vehicles in the Public Service Sector, including Beijing-Tianjin-Hebei Public Transport. At the end of 2015, the proportion of new energy vehicles in buses in the Beijing-Tianjin-Hebei region was not less than 16%, and the proportion of new energy vehicles in taxis in Beijing and Tianjin was not less than 5%.

The significance of this document is that the first and seventh departments jointly issued a document to promote new energy vehicles, which is relatively rare. Second, the work plan proposed this time is practical and has specific goals and proportions. , Revealed the requirements for rigid development.

On the other hand, a few days ago, the National Automobile Production and Sales Data released by the China Automobile Industry Association for the first nine months of 2014 showed that new energy vehicles produced 38,522 units and sold 38,163 units during the January-September period, a year-on-year increase of 2.9 and 2.8 times, respectively.

First look at the data of several groups of subsidies. In 2009, the "Interim Measures for the Management of Financial Subsidy Funds for the Demonstration and Promotion of Energy Conservation and New Energy Vehicles" promulgated by the state proposed that subsidies for pure electric vehicles will be up to 60,000 yuan per vehicle. In 2010, the Ministry of Finance and the State The NDRC jointly issued a document and proposed to subsidize domestic new energy vehicles at 3,000 yuan / kWh, with a pilot period of 2010-2012.

Chen Ping also said, "The state's preferential policies, such as exemption from purchase tax, subsidies, support for electricity prices for charging facilities, and the improvement of new energy vehicle performance and cost reduction, have all contributed to a better situation this year. However, we can see that if there is no subsidy, so many cars may not be sold, and it also involves the promotion of the government. It depends on the performance of the current sales market, mainly buses and taxis; and the rental market. It may involve the cars they produced, bought by their own leasing companies, and received state subsidies before renting them to users. It should be said that subsidies are a big driving force. If there is no subsidy, this market is still facing a large Challenges, so I think it will take some time for new energy vehicles, especially pure electric vehicles, to reach true popularity. "

As a result, the favorable policy of new energy vehicles has emerged a clearer line, and the public transportation service field will become a breakthrough for the government to promote the development of new energy vehicles. ^[4]
