The use of fossil fuels continues in the face of rising global energy demand, continued consumption and investment in new fossil fuel plants, and energy use, the report said. lower biomass such as using wood or agricultural waste in heating and cooking. Burning fossil fuels such as coal, gas and oil produces carbon dioxide, the main greenhouse gas that contributes to global warming. As concentrations of CO2 in the atmosphere rise to record levels, governments have called for stronger emissions cuts and curbs on fossil fuel use to meet global climate goals.

The share of fossil fuels in the global energy mix was 80.2% in 2019, compared with 80.3% in 2009, while renewables such as wind and solar accounted for 11, REN21 said. 2% in the energy structure in 2019 and 8.7% in 2009. The remainder of the energy mix consists of traditional biomass, which is used largely for cooking or heating in homes in the developing world. However, in many regions, including parts of China, the European Union, India, and the United States, it is now cheaper to build new wind or solar photovoltaic plants than to operate new ones. existing coal plant. Renewable energy is also competing with new natural gas-fired power plants in terms of cost in many locations and is the cheapest source of new electricity generation in countries on all continents, the report said. big land. “We are waking up to the bitter reality that the climate policy promises of the past ten years have been almost empty words,” said Rana Adib, CEO of REN21. “The share of fossil fuels in final energy consumption has not shifted an inch,” she added. In many countries, the Covid-19 economic recovery packages aim to stimulate further investment in renewable energy. But renewable investments only account for about one-sixth of investment in fossil fuels, the report added.

Tulip turbines are “planted” in urban areas, on the rooftops of houses in Amsterdam, the Netherlands Traditional wind turbines are often located in the sea, are huge in size, make loud noises, can harm birds, and it is important that very strong winds are needed to generate electricity. The new tulip-shaped design overcomes all of the above shortcomings, it only needs a normal wind to generate enough electricity for a family to use comfortably all day. Israeli-American Dr Daniel Farb, the inventor of the tulip turbine, said the unique aerodynamic design makes the turbines quiet, efficient and capable of generating more than 50% of the electricity in clusters. Shaped like glossy flowers in a variety of colors and sizes (1m, 3m and 6m high), the tulip turbines are designed to double duty as electricity generation and artistic decoration on the rooftops. home, shopping mall, school… In addition, a solar system combined with tulip turbines could reduce overcrowding during the late afternoon peaks in many parts of the world when sunlight goes out and strong winds pick up.

Germany and Norway inaugurated the NordLink undersea cable line. Photo: DW With a total length of 623 km, NordLink is one of the longest undersea cables in the world, connecting the town of Tonstad in southern Norway to the mouth of the Elbe river in northern Germany. This cable route helps to exchange wind and solar energy produced in Germany for hydroelectric power produced in Norway, helping the two countries make up for the shortfall in electricity production due to fluctuations in the amount of wind and sun. The project is expected to help provide electricity for about 3.6 million households, which has been in operation since April, but officially opened on May 27. According to German Chancellor Angela Merkel, the project is really a big step towards a sustainable and future-friendly energy supply for Germany. The project also helps to balance electricity production, which is an important part of the country’s growing efforts to expand renewable energy sources. Thorsten Lenck of the Agora Energy Transition research organization considers the NordLink project an important step in Germany’s energy transition and integration into the European power system. According to the plan, Germany will gradually phase out nuclear power by 2022 and coal power by 2038. Recently, Germany has also set many ambitious targets to reduce CO2 emissions after the Constitutional Court – a court Supreme Court in Germany, ruled that the current climate protection law was “not enough”, demanding an amendment to the law. With ambitious targets, the German government plans to cut emissions by 65% ​​by 2030 compared with 1990 levels, further than the 55% reduction target set earlier. The reduction will then reach 88% by 2040, with the goal of making Germany carbon neutral by 2045, five years earlier than originally planned. For the first time ever, renewables in Germany will account for half of electricity production, compared with 25% less than 10 years ago, data from the Fraunhofer Research Institute shows. Interaction and exchange between different countries is also one of the pillars of the European Union’s climate strategy. To date, a number of cross-border projects have been operating between Norway and the Netherlands; Netherlands and Great Britain; Denmark and the Netherlands.

Control room of Ham Thuan factory with IP-based surveillance camera system Start digital transformation from equipment upgrade projects Concept “ Digital conversion ” has been widely used in the media in recent times. Since it is a new concept, each person can understand digital transformation in his or her own way. However, the basic thing of digital transformation is that the process of digitalization combined with the application of achievements of the Industrial Revolution 4.0 into practice has created many transformations. powerful changes in life. The application of digital technology (Digital technology) has been approved by the Company UD implemented since 2004 when implementing the Da Nhim Power System Restoration Project. Da Nhim hydropower plant was put into operation in 1964 with a control system based on analog signals with countless knobs, knobs, switches, switches… The system of bulky, power-consuming equipment is prone to breakdowns due to its long-term use, reducing reliability. After 40 years of operation, the equipment system needs to be replaced to meet the reliability and efficiency in power production. Operation room of Da Nhim hydropower plant before digitalization Da Nhim power system restoration project (2004 – 2006) was invested by Vietnam Electricity Corporation (now Vietnam Electricity – EVN) and assigned Da Nhim – Ham Thuan Hydropower Company – Da Mi (now Da Nhim – Ham Thuan – Da Mi Hydropower Joint Stock Company: DDD) is the Project Management Board. The project includes 3 main packages to renovate and replace Da Nhim’s equipment system, including: Package No. 1- Generator and electrical equipment; Package No. 2 – Water turbine and water pipeline equipment; Package 3 – Hydrological data collection system. In particular, Package 1 with the application of digital technology to electrical equipment and control systems has created a new and modern appearance for Da Nhim hydropower plant with a stable operating equipment system. , computer controlled high availability, replacing obsolete analog equipment system. The control system with Alstom’s ALSPA P.320 HMI interface combined with GE Fanus’ PLC has created a turning point in operation control. All operation of the device is done by clicking on the computer screen instead of turning the knob or pressing the mechanical button as before. OCC operation room of DHD Company – The first remote control model of power plants in the power industry Da Nhim Hydropower Plant Expansion Project (Operating Phase 1 with a capacity of 80MW in 2018) continues to apply the latest digital technologies to the control equipment system, creating a Da Nhim hydropower plant. more modern. Inheriting their knowledge and experience through the Da Nhim Restoration Project, the Ham Thuan – Da Mi Hydropower Project, from 2008 to 2010, the Company’s engineers UD has successfully researched, programmed and put into operation the DCS system of Song Pha hydropower plant with a combination of WinCC control interface and Siemens S7-300 PLC. With the new control system, Song Pha hydropower plant seems to be wearing a new shirt, the outdated analog control system has been completely replaced by digital equipment. Operation room of Song Pha hydropower plant in 2006 The memorable milestone of the application of Science and Technology 4.0 in power production operation was in 2013 when the General Assembly Company and the domestic contractors successfully installed and put into operation the Operation Control Center (OCC – Operation Control Center). Center). This is considered the first OCC center at power plants in Vietnam to remotely control power plants. Since the OCC Center came into operation, combined with the IP-based CCTV system, DHD Company has optimized its operation and improved labor productivity. With OCC’s remote control and monitoring capabilities, the number of operators at hydroelectric power plants is reduced from 5 to 2 to 3. The OCC model of AGM Company was then replicated to other units in the industry and brought many practical benefits. The operation room of Song Pha hydroelectric power plant is now with the control system designed and installed by DDH Company Combining digitization and industrial science 4.0 Responding to the digital transformation of Electricity of Vietnam (EVN) and Power Generation Corporation 1 (EVNGENCO1), the General Assembly Company applied the results of the Industrial Revolution 4.0 on the digital platform to create a remarkable transformation in production management and administration. On the digital platform that has been deployed at power plants, DDT Company has gradually upgraded telecommunications infrastructure to create a smooth connection between the OCC Center, power plants and dispatching centers for business purposes. operate production and offer electricity prices in the market with high efficiency. The application of IP-based surveillance camera system helps the operator to monitor lake water level, discharge status of water supply to downstream… creating many advantages in coordination between the Company and local authorities in the company. disaster prevention and search and rescue. For administration, the General Meeting of Shareholders thoroughly handles incoming/outgoing documents, internal documents, on the e-Office system while accelerating the speed of case handling and convenience in work. storage and retrieval while saving printing paper and protecting the environment. In the bidding work, the Company conducts online bidding to ensure that information is provided to contractors quickly and accurately, to ensure transparency in bidding and to save printing costs. Currently, cloud computing technology (i-Cloud) is widely applied and becomes more and more familiar to the employees of the Company. The company has registered a Google Drive account with unlimited storage, sharing capacity to each unit for use. Employees store files and documents on shared Google Drive so that they can easily perform their work on smartphones and tablets even if they are far from the working location. Using i-Cloud for work has become popular at the University of Da Nang Timekeeping, collection of opinions, statistics, surveys, etc. when there is a need for the coordination of many people, is easily done by Google tools such as Google doc, Google sheet, Google form. The digital transformation is making the work processing steps at the General Meeting of Shareholders more and more convenient, in line with the general trend of the whole society. E-learning is also being applied and achieving positive results. Digital transformation plan at the Company in the next period Although the digital transformation is bringing initial results, creating many advantages in operation and production and business, in order to achieve greater results, AGM needs to further promote infrastructure investment Information technology combined with human training. Mr. Le Van Quang – General Director of DHD Company commented: “Digital transformation has brought practical results that every employee in the Company can clearly see. Previously, employees in the Company had to save each monthly pay slip to track their income, now they can look up information about income, vacation days, earnings, deductions… through through payroll software developed by the Company itself. This is an example of digital transformation at AGM.” Following the direction of EVN and EVNGENCO1, the General Meeting of Shareholders established a Steering Committee for Digital Transformation and Technology Application of the 4th Industrial Revolution in production and business activities at the Company by the Chairman of the Board of Directors. serve as Head of the Board. According to the Digital Transformation Plan for the 2021-2025 period, the General Meeting of Shareholders focuses on two major areas of work, including: Applying digital transformation in governance, administrative reform, improving labor productivity and Modernizing systems and infrastructure. In governance, the Company continues to carry out typical tasks such as: Raising awareness about digital transformation, capacity to use information technology for management and employees; Provide digital signatures for all employees in the Company; Establish a library, store documents on Google Drive; Do 100% internal writing via E-Office; Renovate the company’s web, build an online web-based working environment, to share resources, manage work, create the ability to work anytime, anywhere, any means; Building a forum for questions (of employees) and answers (of experts in the company), serving training; Digital invoice management; Digitizing internal and external reports; Record device parameters online on the basis of image recognition; Operation log no… Continuing, modernizing the equipment system and infrastructure, DDT Company will perform the following items: Setting up an unmanned Da Nhim Water Purification Station; Carrying out scientific research on unmanned power plants for Da Mi Solar Power Plant, Song Pha Hydropower Plant; Upgrade the IT system operation monitoring center, information security policy for information security, according to ISO 27001 standard; Complete security for information systems according to the specified safety level.

Illustration. https://tinhtexaydung.petrotimes.vn In a statement released alongside a major new report, the Paris-based organization said achieving the net zero emissions target “Net Zero” would require an “unprecedented transformation”. about how energy is produced, transported and used globally”. In a clear indication of the amount of work that needs to be done, the IEA report said existing commitments fell “far below what is needed to achieve net-zero global emissions by”. year 2050″. According to the IEA’s roadmap to achieve Net Zero by 2050, more than 400 “milestones” will need to be crossed. These include phasing out new fossil fuel sales by 2025 and ending sales of internal combustion engine cars by 2035. In addition, there should be no “investment in new fossil fuel supply projects, and no further final investment decisions for new coal plants”. Preliminary figures from the US Energy Information Administration show that: The share of natural gas and coal in utility-scale power generation in 2020 is 40.3% and 19.3%, respectively. . According to the IEA scenario, solar and wind photovoltaic will become the leading source of electricity for the planet before the end of the decade, accounting for nearly 70% of electricity production by 2050. According to the IEA’s roadmap, solar energy will become “the largest source of total energy on the planet” by the middle of this century. In contrast, fossil fuels will see their market share “fall from almost four-fifths of total energy supply today to more than one-fifth.” Employment in the clean energy sector will increase by 14 million people in the period to 2030, while the role in the oil and gas and coal sectors will decrease by about 5 million people. “Our roadmap shows the priority actions needed today to ensure that the opportunity for net zero emissions by 2050 is narrow but still attainable,” said Fatih Birol, CEO. of the IEA, said in a statement. “The scale and speed of the efforts required by this important and formidable goal, our best chance of tackling climate change and limiting global warming to 1.5 °C makes this perhaps the biggest challenge humanity has ever faced,” added Birol. Cutting anthropogenic carbon dioxide emissions to Net zero by 2050 is considered critical once the 1.5°C target is reached. Later this year, the COP26 summit will take place in the Scottish city of Glasgow. This is seen as a hugely important event, with many hoping it will act as a catalyst for governments to step up their climate ambitions to achieve the goals set out in the Paris Agreement. . The reality shows how challenging the IEA’s roadmap is. As energy companies are still discovering new oil fields, while in countries like the United States fossil fuels continue to play an important role in electricity generation. https://tinhtexaydung.petrotimes.vn

Elon Musk declares allegiance to Dogecoin (Image: WCCFTech) Elon Musk declared his allegiance to Dogecoin causing its value to increase by 15% during this crypto volatility. The billionaire American businessman responded to a Twitter thread speculating about his Dogecoin holdings with the message: “I have not and will not sell any Dogecoins.” This move of Elon Musk immediately caused Dogecoin to increase in value after many days of falling. Earlier, the CEO of Tesla and SpaceX posted on Twitter a photo of a laptop with a $1 bill sticker on it with the caption: “How many Doge’s in the window.” If you look closely, you can see that this bill has a picture of a Shiba Inu dog, the symbol of Dogecoin, in place of President George Washington. Elon Musk’s post on Twitter (Image: Twitter) This is the second time this week that Elon Musk has publicly expressed support for cryptocurrencies, after making an announcement on Twitter that Tesla would hold onto its Bitcoins as the market shows signs of a market crash. Earlier, Elon Musk faced criticism from social media users when some suggested that he sold his Bitcoins when its price peaked in the market. Elon Musk responded by tweeting that the electric car company has a “Diamond Hand,” referring to traders who hold stocks when prices fall with the goal of making long-term profits. The drop in cryptocurrency value over the past few days is said to have started after Elon Musk posted an announcement saying that Tesla was temporarily suspending Bitcoin as payment for its car orders, due to concerns about the risk of loss of money. Bitcoin mining will have a bad effect on the environment. Since then, however, he has repeatedly said that the company will keep its Bitcoins and will allow the use of the cryptocurrency to trade again when mining becomes more stable. Elon Musk announced that he will not sell Tesla’s Bitcoin (Image: Twitter) According to the Cambridge Center for Alternative Finance, the Bitcoin industry’s annual energy consumption is on par with that of a country the size of Malaysia. And most of the mining is located in regions of China, where electricity is produced cheaply by coal-fired power plants. Tesla bought $1.5 billion worth of Bitcoin at the end of 2020 when the price of each Bitcoin was below $20,000 and sold 10% in early 2021 when the price of this virtual currency reached $50,000/Bitcoin, earning on a profit of 101 million USD.

On May 21, G7 pledged to completely stop funding coal-fired power plants. On May 21, environment ministers from the Group of Top Industrialized Countries (G7) agreed to take concrete steps by the end of the year to stop government funding for coal-fired power plants as part of efforts to curb global warming. In a statement after the two-day video conference, the G7 environment ministers said: “(We) are committed to taking concrete steps towards an absolute end to the new direct government assistance. for international coal-fired power generation by the end of 2021, including through Official Development Assistance (ODA), export finance, investment, financial support and trade promotion” . However, the statement did not mention the possibility of phasing out coal-fired power generation, leading analysts to believe that the G7’s call would have little impact on global efforts to tackle the problem. climate change issue. The removal of government support for fossil fuel financing, which emits large amounts of greenhouse gases that warm the Earth, is seen as essential to limiting the growth of fossil fuels. global temperature increase at 1.5 degrees Celsius, above pre-industrial levels. (according to Kyodo)

Power lines connecting high-voltage poles near the capital Brasilia (Brazil). Photo: Reuters. According to ONS General Manager Luiz Carlos Ciocchi, this could lead to higher electricity prices. However, the situation is still positive when the risk of power shortage or interruption of distribution has not yet occurred. About three-quarters of Brazil’s electricity is generated from hydroelectric plants. This is one of the largest percentages compared to countries in the world. Brazilian President Jair Bolsonaro said on May 10 that the country was experiencing the worst water crisis in its history, and warned of major problems with electricity production. The crisis comes at a time of increased demand for energy, as temperatures rise in the coming summer months. Last week, Brazil’s Electricity Supervision Commission approved potential additional measures to meet electricity demand, including increasing the power output of thermal power plants and importing energy from Argentina and Uruguay. Mr. L.Ciocchi said that the government should reserve water in the lakes to meet the needs of the people and maintain the necessary hydropower output.

This time started in the summer, the demand for cooling devices increased, leading to a dizzying increase in electricity bills, so solar fan models were sold on the market. They are advertised, instead of running on electricity like conventional types, this type of fan operates entirely on solar power. Specifically, each solar fan will come with a solar panel to help absorb sunlight and produce electricity to maintain operation. Depending on the type of panel, when placed in the sun, the fan controller will charge the battery, which takes 4-6 hours. After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers. For example, the 20W mini solar fan line is being discounted by up to 50%, from VND 830,000 to VND 417,000; mini fan 3.5W X9E is 40% off, from 510,000 VND to 306,000 VND; The Sunisi FT-30 fan model is priced at 1 million VND, 50% less than the original price of 2.1 million VND; Korichi KRC 6300 fan model reduced from 1.2 million VND to 890,000 VND; Jenpect 220V fan model has the original price of 1.3 million VND, down 34%, now only 850,000 VND,… According to the advertisement of the staff of household electrical stores, compared to traditional fans, solar fans have many advantages such as: no electricity costs, no fear of sudden power outages in hot summer days. Not only that, they are also very convenient when going on a picnic or camping trip; can directly charge other mobile devices such as phones, flashlights, … via USB port, which is very convenient. Moreover, long battery life 3-5 years of use, battery capacity up to 12,000 mAh, using time up to 8-12 hours. With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.

A solar power plant in Maryland, USA. (Photo: AFP / VNA) A unit of the company Samsung C&T is considering investing $ 673 million in the construction of solar power plants in Texas (USA), to start commercial production in December 2023. The solar facilities above will be located in Milam County, Texas, less than two hours ‘drive from Samsung Electronics’ chip factory in Austin. Austin is where Samsung is considering building a new $ 17 billion chip factory. With a capacity of about 700 MW, solar power plants will begin construction in June 2022. A Samsung C&T official said the company is doing the approval procedures with the authorities. The attractiveness of solar and wind power is increasing rapidly as nations around the world switch from fossil fuels to cleaner renewable sources to prevent global warming. The administration of US President Joe Biden aims to generate electricity from non-carbon sources such as nuclear and renewable energy by 2035. Recently, South Korean President Moon Jae-in also pledged to end all new funding for overseas coal projects and will soon come up with a more ambitious plan to cut carbon emissions. . In October, Samsung C&T Corp announced its decision to suspend any new projects or investments related to coal. While chip makers like Samsung Electronics, Intel and TSMC are also committed to increasing the use of renewable energy to reduce carbon emissions.

In Ninh Thuan province, the Cyclic Energy Solution Company (CAS Company) is applying the model of goat farming and experimental planting of trees under panels at 3ha large solar farm. However, Mr. Tran Anh Dong, Director of CAS Company, said: “The company’s main revenue is from solar power, while the revenue from agricultural production is still low. Currently, the company is still struggling in finding high-yield crops suitable for the conditions to be planted under solar panels ”. According to Nguyen Quoc Khanh, the model of solar power combined with agriculture has great potential, both increasing the efficiency of land use and creating more income for farmers. However, at present, this model still has many limitations such as: Not meeting farm economic criteria, no support mechanism for solar power, lack of information on suitable crops, no technical guidance, lack of practical model … In order for this model to really promote its effectiveness, the State needs more mechanisms and policies to help businesses overcome the above problems.

However, electric cars are not perfect and they come with their own pollution problems. Typically, their batteries contain ingredients such as lithium, which require a considerable amount of energy to source and extract.

However, making batteries is only part of the life cycle of electric vehicles. A 2014 study published in the Proceedings of the National Academy of Sciences looked at the entire emissions life cycle of an electric vehicle, from mining the metals needed for batteries to producing the electricity needed. to power them, then compare this to the average emissions of a gasoline car. The team found that when electric cars are charged with coal-fired electricity, they actually do more harm to the environment than conventional gasoline cars.

Buying an electric car is much more affordable than a gas or diesel from an environmental perspective. Illustration

But that is not a problem because today, in most countries around the world, the national grid is “clean” enough for electric cars to beat competitors running on gasoline.

There are very few countries in the world where the grid is entirely or mostly coal. China is one of them. In 2019, an estimated 58% of the country’s electricity supply comes from coal. China’s grid is improving, however, with more investments in renewables – for example, it has twice the capacity of wind power as the US and builds more solar panels than any other country. Every year, according to Nature.

Mr. Gordon Bauer, an electric vehicle researcher at the International Council for Clean Transport in San Francisco, USA, said the current improved grid model, with more renewable energy and less fossil fuels. , is a global model and helps improve the environmental quality of electric vehicles. “As the grid becomes” greener “, the use of electric vehicles will be more perfect,” he said.

In a study published this month in the journal Environmental Science and Technology, Colin Sheppard, a researcher in energy and transport systems engineering at Lawrence Berkeley National Laboratory in California, Work with Gordon Bauer to model a hypothetical future scenario where all cars are powered by electricity. “We want to understand the impact of energy, infrastructure and emissions if all passenger vehicles are electrified,” Sheppard told Live Science.

For example, Mr. Sheppard calculated that if all private vehicles in the United States were powered by electricity, the annual reduction in greenhouse gas emissions in the country would be 46% (0.5 gigatons of CO2) compared to cars. run on conventional gas.

This reduction could be further increased if the vehicles were subjected to so-called “controlled charging”, a technique also known as “smart charging”, in which the vehicles are recharged into Timing is selected to minimize the financial cost of electricity generation. (For example, charging at night is generally less expensive than during the day; this strategy also favors plants that produce more energy efficiently to generate cheaper electricity.) If all privately owned electric cars were charged in the same way, emissions savings could be increased by up to 49% annually.

In addition, electric vehicles are said to also emit CO2, but not during use, but when generating electricity – this is why many people believe that this car is not completely pure. Even the president of Toyota once harshly said that electric cars are being overblown.

In fact, electrochemical vehicles including Hybrid (HEV), Plug-in Hybrid (PHEV) still emit CO2 even when used (because there is still an internal combustion engine) and possibly when generating electricity, depending on how it is generated. electricity. While pure electric vehicles can only generate CO2 in the production process, not when used.

Depending on the source of electricity generation is hydroelectricity, wind power or thermal power, nuclear power … that the amount of CO2 generation will be different. If hydroelectricity, CO2 level is almost zero, while thermal power is too much CO2.

Research by Bloomberg NEF in Thailand shows that electric cars generate 60% of the CO2 equivalent of a gasoline equivalent vehicle. This source of CO2 comes entirely from production, because Thailand generates electricity mainly from natural gas. While internal combustion engine vehicles produce CO2 in an 80/20 ratio between use and production.

For example, if a gasoline car generates 100 g CO2 / km 80 g from use and 20 g from gas production. While a corresponding electric car model only generates 60 g of CO2 from use. As such, electric cars are still significantly cleaner than gasoline cars.

For countries with clean electricity generation sources such as Norway, up to 95% of electrical energy comes from hydroelectricity, CO2 emissions are even lower. The future of electric vehicles is becoming clearer as more automakers are involved in the production and research of electric vehicles. Users often do not care too much about CO2 emissions in production, but realize that when used, it will help where cars circulate with less pollution.

Ultimately, the conclusion is that buying an electric car is much more affordable than a gas or diesel car from an environmental perspective.

With the results achieved in the first quarter, Pha Lai Thermal Power has completed 19% of the revenue plan and more than 35% of the profit plan.

As of March 31, 2021, the company’s total assets reached more than VND 6,715 billion, down 7% compared to the end of 2020. In which, cash and cash equivalents decreased sharply by more than 66% to 92 billion VND. . Short-term receivables from customers also decreased by 35% to more than 975 billion.

Total liabilities at the end of the first quarter of 2021 reached VND 478 billion, a decrease of over 36% compared to the end of 2020, of which the decrease was mainly in short-term payables to sellers.

The number of car charging stations is increasing globally and also in Vietnam.

The energy provided for electric vehicles is increasingly clean

The REN21 Global Renewable Energy (GSR) Report of 2020 (Global Multilateral Renewable Energy Policy Network) shows that, over the past 5 years, the renewable energy sector has reached its speed. 3 times higher than electricity produced from nuclear and fossil fuels.

“When the grid becomes ‘greener’, using electric vehicles will be more perfect ”, Gordon Bauer – electric vehicle researcher at the International Council for Clean Transport in San Francisco (USA) said. According to expert Gordon Bauer, the current innovative grid model will help improve the environmental efficiency of electric vehicles around the world.

The evidence is a study by scientists at the Lawrence Berkeley National Laboratory in California (USA) that if all personal vehicles in the US are powered by electricity, each year, the country will lose 46%. greenhouse gas (0.5 gigatons CO2 equivalent) compared to conventional fossil fuel cars.

This is what environmental activists expect. Anne Laurent, president of the All-European Environmental Union, admits the members “have no doubts” about the positive impact this vehicle can have on the planet.

“We do not expect a perfect solution. Therefore, we are delighted that electric vehicles deliver positive environmental indicators“Ms. Laurent said in a report released at the end of 2020.

In Vietnam, green vehicles are also developing with the launch of private cars and VinFast electric buses. And look at “National energy development strategy to 2030, vision to 2045” – with the goal that the renewable energy in the total primary energy supply will reach 15 – 20% by 2030 and increase to 25-30% by 2045 we have the right to hope for a “green future, clean air” when clean cars are powered by clean electricity.

Electric vehicle batteries are too expensive to be … garbage

In addition to generating electricity, environmental activists have been concerned about the fate of electric vehicle battery blocks after they have run out of “trumps”. Elon Musk was the “victim” of this wave of protest. But in fact, electric car batteries can not be thrown away because … too expensive, even after the expiry date.

The reason is that the prices of cobalt, lithium, nickel and the metals used in lithium-ion batteries have skyrocketed as the electric car race intensifies between manufacturers across Asia to Europe and the US. Therefore, all electric car manufacturers are researching and announcing solutions to handle expired batteries with battery recycling technology.

“To meet electric vehicle battery demand in the next 10 years, the industry will need 1.5 million tons of lithium, 1.5 million tons of graphite, 1 million tons of nickel and 500,000 tons of manganese. Today, the world produces less than a third of that material ”Sam Jaffe, CEO of Cairn ERA, an energy consulting firm in the US, told CNBC.

Some studies show that recycling can recover between 95 and 98 percent of the nickel, cobalt, copper, aluminum, and more than 80 percent of the battery’s lithium. Ms. Celina Mikolajczak, Vice President of Battery Technology and Technology at Panasonic Energy North America, said that the battery recycling industry will be a billion-dollar land with the development of electric vehicles.

“There are so many benefits to recycling and it would be really stupid if we didn’t take advantage of the old battery cells’ ability to make the next generation.”Ms. Celina Mikolajczak confirmed.

This excellent solution not only eliminates the worry of running out of production materials, but also removes electric vehicle batteries from the burden of the environment.

There are more than 50 companies around the world engaged in the recycling of lithium-ion batteries of varying sizes, most of them concentrated in China (more than 20 companies), followed by Korea (6 companies), followed by the EU, Japan, Canada and the US. Even global tech giant Amazon hasn’t overlooked this potential by investing $ 2 billion in Redwood Materials, a battery recycling startup founded by former Tesla chief JB Straubel. Redwood Materials is also responsible for recycling electric vehicle batteries for Tesla.

In addition to recycling batteries for reuse for electric vehicles themselves, a series of projects to utilize old batteries have been implemented recently by car manufacturers. Toyota has a project to connect old electric vehicle batteries with solar panels to power 7-Eleven stores in Japan; Nissan is using old batteries to power the small robots; Renault is working with its partners to introduce static energy storage systems made of old electric vehicle batteries … Other car manufacturers such as Audi, BMW, Lucid Motors or Proterra … are also incorporating reusable principles into their designs. the battery.

“We believe that the ‘second life’ battery will become an independent business and cannot be disposed of as trash.”, Weiland Bruch, BMW spokesman forecasts.

When the final concern was that electric vehicle batteries turned into environmental waste were completely eliminated – it’s easy to understand why green cars are supported by environmental activists around the world. And that will also be the green future that we need to move towards to escape the country’s “scandal” of the “two-wheeled gas factories” that international indicators set for Vietnam.
