How can the utilization of new energy be "generalized"

wind energy, solar energy, bioenergy and nuclear energy today, a variety of new energy are emerging in endlessly, and many energy enterprises have also invested in the development and utilization of new energy. But the actual situation is that under the current state, it is impossible for us to abandon traditional energy and replace it all with new energy. Moreover, the new energy with mature technology also has various instabilities and is not suitable to completely replace traditional energy

how to comprehensively utilize these new energies, give full play to their respective advantages and improve energy efficiency is one of the important topics at present. Experts believe that energy development is no longer simply aimed at a single technology innovation, but integrates various processes such as clean energy utilization, carbon recovery and application, renewable energy development and application, and the complementarity and transformation of various energies on a unified platform. Thus, the concept of universal energy gradually surfaced

new energy in full bloom

the Shanghai WorldExpo is the world's largest experimental site for the use of new energy, where a variety of new energy in full bloom, dazzling people

the concept of solar energy was first fully introduced into the Expo site. A large area of solar panels are laid on the roof of the Expo Theme Pavilion, and the parallel power generation operation mode is adopted to telex the solar energy back to the urban power. The solar panel covers an area of 30000 square meters, with an annual power generation of 2.5 million kWh and 2.57 MW. This will be the best Expo ever. In the Expo site, visitors will likely see various solar landscape lights and solar sculptures, as well as the solar corridor on both sides of the Huangpu River, which can both shelter from rain and generate electricity

as one of the first pilot cities of the national demonstration and promotion of energy-saving and new energy vehicles, Shanghai will demonstrate and operate a total of 1017 new energy vehicles including pure electric, hybrid, fuel cell, etc. during the Expo in combination with the Expo science and technology action plan. Among them, there are 321 pure electric vehicles, 500 hybrid electric vehicles and 196 fuel cell vehicles. This is another centralized display of China's new energy vehicle technology achievements after the 2008 Beijing Olympic Games. In order to support the demonstration operation of Expo new energy vehicles, a new charging station has been built in the Expo Park to supply energy for pure electric buses that use rapid battery replacement. At the same time, a charging line has been built on Expo avenue to provide rapid charging for super capacitor buses at each station

in addition to new energy, low-carbon technology and low-carbon creativity are also omnipresent in the Expo Park. The breathable floor, the leftovers that can generate electricity, and the walls that can maintain temperature and glow in the zero carbon Pavilion in London all brighten people's eyes. Hamburg house effectively utilizes the waste heat of passive heat sources such as human body and indoor appliances to meet the vast majority of indoor energy needs

for example, the five story building of Shanghai eco home is made of waste bricks from the reconstruction of the old city of Shanghai. The light chasing shutter on the roof can automatically change the angle with the change of the sun's angle, and the potential energy up and down the elevator can also be stored for its own use. In addition, the Spanish Pavilion uses vines as building materials, the African Joint Pavilion built with China's assistance is made of recyclable iron, and the rainwater collection system is widely used throughout the Expo site, making the Shanghai WorldExpo a truly green WorldExpo

it is learned that many of these energy-saving and low-carbon technologies are relatively advanced technologies in the world. Although they are still in the demonstration stage, the attempt of the WorldExpo will make them more mature and meet the actual application requirements, realize industrialization faster, and then promote large-scale applications. Take new energy vehicles as an example. After the World Expo, the hybrid vehicles developed by SAIC will be launched in batches, and the 20% fuel-efficient SAIC Roewe 750 medium hybrid car and other models will be mass produced

at present, the performance of fuel cell vehicles developed in Shanghai has been steadily improved, and the comprehensive cost has decreased by more than 20% compared with last year. In terms of the promotion policy of new energy vehicles, Shanghai is expected to try out business models such as vehicle installment payment, battery financial leasing, mileage consumption settlement, and will also promote the construction of supporting infrastructure such as more than 7-10 charging (discharging) power stations and about 400 charging piles. Since it is no longer a novelty to pack ketchup with flexible and larger vertical bags. In addition, the comprehensive demonstration project of smart electricity in Pudong Park will continue to play a role after the Expo. It will not only be effective for permanent buildings such as the China Pavilion and Theme Pavilion, but also for new buildings in Pudong area of the Expo

universal energy improves comprehensive energy efficiency

new energy shines brightly at the WorldExpo, but there is still a long way to go before these technologies can truly enter the homes of ordinary people. All kinds of new energy have their own advantages and disadvantages. How to comprehensively utilize all kinds of new energy and give full play to their maximum energy efficiency is the focus of current attention

for example, the power of wind energy comes from natural wind, and the process of generating electric energy does not produce new pollution. It can be described as an excellent clean energy. But generally speaking, when a large amount of electricity is needed during the day, the wind is not very strong, but when the electricity is used at night, the wind is very strong. Similarly, solar power generation is not very stable. On cloudy, rainy days or at night, the power generated by solar energy is much inferior. More importantly, it is not practical to completely replace traditional energy with new energy at present. On the one hand, at present, the existing buildings account for the vast majority. To carry out energy-saving transformation on the basis of the existing buildings, not only the cost is very high, but also the procedure is relatively complex; On the other hand, so far, a single new energy can not completely replace traditional energy because of its instability. Experts said that if only a single energy is used, it needs to be equipped according to the highest value, and in most cases, people will not reach this peak, which will not only cause a waste of energy, but also a waste of corresponding energy hardware

therefore, when some enterprises launched the new concept of fanneng, it attracted great attention in the industry

in short, universal energy is intelligent energy. Through intelligent means, according to the energy characteristics of customers, relying on clean energy technology and with the help of Internet technology, we can provide intelligent platforms and energy solutions for new energy customers, so as to realize a new industry that combines system energy efficiency technology with it intelligent technology. For example, the solar holographic integration technology on the roof can make full use of the full band spectrum of solar energy, which runs through the four life cycles of solar energy from production, storage and transportation, application and recycling, and realize the best comprehensive application of the four energy efficiency of solar energy: light, heat, electricity and photochemistry. At the same time, domestic cogeneration based on fuel cells can show the unique advantages of fuel cells to meet the needs of household electricity and domestic hot water in the case of urban power failure and no sun and wind. Through the intelligent information system, these energies will be integrated on the same platform, and the utilization and transformation of different energies will be carried out at an appropriate time

the greater the use of Pan axial tension, in the future buildings, different types of hydraulic universal testing machines will mainly test the physical characteristics of raw materials, finished products and semi-finished products, and the source can also be centrally managed. The control system can reasonably allocate and convert different forms of energy according to the actual needs of different households. Energy flow is like having wisdom, knowing how to work most efficiently, when to use what kind of energy to provide energy, so as to reduce energy consumption, minimize emissions, and achieve household energy conservation and emission reduction. It can be clearly seen from the simulation demonstration of Pan energy in the National Pavilion of China that under the effective management of Pan energy, in addition to the effective utilization of renewable energy such as wind energy and solar energy, traditional coal based energy can also be efficiently developed and cleanly utilized through technologies such as underground gasification, catalytic gasification, cogeneration of gas and electricity, and biological carbon absorption by Weizao

industry barriers need to be eliminated

energy can flow and distribute in different energy bodies like water, which is the bright prospect described by universal energy for us. However, in order to realize the transformation between different energy sources, we need to eliminate various barriers. Only through the cooperation of all forces can we truly maximize energy efficiency

experts said that at present, the technology of energy efficiency rigidity and hardness of the system is still under development, and there are still many difficulties and barriers in the large-scale promotion of universal energy. Among them, the biggest obstacle lies in the barriers between industries. For example, at present, the power generation efficiency of power plants is 37%-40%, and 55% of it turns into heat energy. Power plants generally recycle only a small part of it, and other heat energy is wasted. If the barrier can be broken, the heat utilization efficiency can be greatly improved. Some experts called on the state to provide policy support in addition to taking the initiative to break down barriers among enterprises. If the barriers of the energy industry can be broken, the saved energy is equivalent to a Gezhouba hydropower station

at the same time, the increase in the initial cost of the energy efficiency system is also a big problem. Some studies have pointed out that the establishment of an energy efficiency system will probably increase the cost of enterprises by 5%-8%, but this can be made up by improving energy efficiency. As long as national policies help to break barriers, the whole system may recover its investment cost in a year to a year and a half. At the same time, the government's incentive policy is also essential. For example, in the field of new energy vehicles, the United States has introduced a number of energy bills and national plans in the field of automobile transportation. In terms of the strategic choice of developing vehicle energy, the United States has changed from the single development pattern of focusing on the research and development of fuel cell technology in the past to the diversified pattern of joint development of hydrogen fuel cell, hybrid power, advanced diesel, bioethanol, biodiesel and other technical routes, making the development of new energy vehicles in the United States take the lead in the world
