The tweet that the Tesla CEO released Sunday was part of an exchange with twitter users that omitted to refer to a CoinTelegraph article accusing him of “bitcoin manipulation.” Musk said that the company kept $1.5 billion of its initial investment in bitcoin, but sold about 10% to “confirm it’s easy to pay off.” [bằng bitcoin] without distorting the market”. Elon Musk has become a prominent and influential figure in the crypto world. He tweeted in May that Tesla would no longer accept bitcoin as a means of payment for its vehicles, citing the large amount of carbon emissions in bitcoin mining. esla will continue to allow transactions in bitcoin at the car manufacturer’s stores, once it is confirmed that the “mining” energy source is clean energy. Photo: Getty. This action is believed to be the cause of the sell-off of the world’s No. 1 cryptocurrency. Musk’s comments on the sustainability of bitcoin “mining” continue to resonate in the crypto community. A commonly cited metric from the University of Cambridge pegged the annual electricity consumption of bitcoin mining at around 99 terawatt-hours. This consumption is more than that of the Philippines or Pakistan. Some of Musk’s recent tweets have also sparked a mix of excitement, confusion, apprehension, and sometimes even fear in the crypto community. Earlier this month, investors attempted to analyze a mysterious tweet from SpaceX that included a bitcoin symbol and a broken heart emoji. The information that Elon Musk transmits has had a great influence on the price of dogecoin and bitcoin. Musk is also partly blamed for the current drop in bitcoin and the broader cryptocurrency complex. The Wall Street Journal has described him as the biggest influence on bitcoin. By the end of June 13, the bitcoin price was up nearly 8%, changing hands at $38,808.09 on CoinDesk. As of now, Bitcoin is up over 28% for the year but is down about 40% from its mid-April peak at $64,829.14. The world’s No. 2 cryptocurrency, Ethereum, gained nearly 5%, changing hands at $2,521.81. Back in February, Tesla revealed that it had acquired about $1.5 billion in bitcoin in a filing with the Securities and Exchange Commission. At the time, Tesla paid about $38,000/bitcoin for each bitcoin. This is the average price at the time of Tesla’s Q4 conference on January 27. This conference did not mention any bitcoin holdings and the date of filing with the SEC. Overall, the prices of digital assets like bitcoin are outperforming traditional markets.

Billionaire Elon Musk speaks at an event. Photo: AFP/VNA Tesla Inc CEO, billionaire Elon Musk, on June 13 posted on his personal Twitter page that the electric vehicle maker will accept bitcoin transactions when miners use a lot of energy. more renewable in the operation of “mining” this digital currency. The post of the head of Tesla states: “Once there is confirmation of a reasonable (about 50%) use of clean energy by miners with an upward trend in the future, Tesla will continue to allow bitcoin transactions”. Bitcoin jumped 5.1% to 37,360.63 USD/bitcoin on June 13 following the post of billionaire Elon Musk. The above post comes after the scientific journal Nature recently published a study that found China’s bitcoin “mines” pose a threat to the country’s climate goals. These mines account for nearly 80% of the world’s cryptocurrency transactions and partly use the energy of coal-fired power plants. Billionaire Tesla expressed his belief that digital currency has a promising future, but it cannot come at a hefty price for the environment. In addition, Mr. Musk also reacted to the article raising the possibility that billionaire Elon Musk regularly affects the value of bitcoin in one direction or another for his business benefit. The Tesla chief said that the company sold about 10% of its bitcoin holdings to confirm that the digital currency has easy liquidity without volatility to the market. Earlier in February 2021, Tesla revealed that it had purchased $1.5 billion in bitcoin and would accept it as a form of payment for cars. But in May, billionaire Musk reversed the decision, citing long-standing environmental concerns around mining this coin. Bitcoin dropped more than 10% in value shortly thereafter.

(Source: Reuters) The leading electric car manufacturer Tesla (USA) will again accept vehicles pay in bitcoin when the process of “mining” this cryptocurrency is certified to use clean energy. Tesla CEO, Billionaire Elon Musk announced the above information on June 13 and immediately caused bitcoin to increase 5.1% in value, to $ 37,360.60 at 1:10 am on June 14 (Vietnam time). Billionaire Musk said Tesla will restore use bitcoin coin in payment transactions when “miners” certify that 50% of the electricity used to “mine” cryptocurrencies is clean energy and identify this as a positive trend in the future. Bitcoin and other cryptocurrencies are the “rewards” obtained after the process of “mining” with specialized miners that solve computational problems that allow linking blocks of transactions (blockchains). This process consumes a large amount of energy. In May, billionaire Musk announced Tesla will no longer accept bitcoin as a means of payment in its purchases. The announcement reverses Tesla’s decision in late March to accept payments in bitcoin and invest $1.5 billion in the digital currency. According to the graph of Bitcoin Mining Power Consumption Index produced by the University of Cambridge (CBECI), the energy use for “mining” cryptocurrency has increased continuously since 2016, even skyrocketing in 2020 and up The current level is 149 terawatt-hours (TWh), an all-time high.

On June 13, Tesla CEO tweeted that he will accept Bitcoin electric vehicle payments again. However, this only happens when Bitcoin miners can prove that about 50% of the energy they use is clean energy. According to Reuters, Bitcoin price increased 5% to 37,360.63 USD at 1:10 am on June 14 (Vietnam time) after Mr. Musk’s tweet. Musk also said that Tesla will sell about 10% of its Bitcoin holdings to show that Bitcoin can be easily liquidated. During the first quarter of the year, Tesla sold about $272 million in “virtual assets,” which reduced its operating loss by $101 million. Tesla CEO comments about cryptocurrencies often cause price fluctuations. As a result, he was criticized by CEO Magda Wierzycka of asset management company Sygnia as a “market manipulator” and that the US Securities and Exchange Commission (SEC) should investigate. In February, Tesla revealed in an SEC filing that it had purchased $1.5 billion in Bitcoin and would accept Bitcoin as payment for its products. However, then the electric car company paused due to concerns about the method of mining virtual currency, which requires huge electricity consumption, affecting climate change. “We are concerned about the rapidly increasing use of fossil fuels to mine and trade Bitcoin, especially coal, which is the worst emitter,” Musk tweeted in May.

The idea behind the study of nuclear fusion is to recreate how the Sun generates enormous amounts of energy, a process involving a large amount of heat and pressure that combine to form plasma, in which atomic particles fuse. with super speed. Scientists are looking to trigger and study these reactions on Earth with a variety of experimental equipment, but experts say that EAST, located at the Hefei Institute of Physical Sciences of the Academy of Sciences Chinese studies, is the most promising approach. Inside China’s “Artificial Sun”, the Tokamak Superconducting Reactor (EAST). Photo: Newatlas. The EAST is a metal toroidal device consisting of magnetic coils designed to sustain streams of superheated hydrogen plasma long enough for the above reactions to occur. In 2016, scientists at EAST heated a hydrogen plasma to about 50 million degrees Celsius and maintained it for 102 seconds. Then in 2018, they hit 100 million degrees Celsius, six times hotter than the Sun’s core, and lasted 10 seconds. According to the Xinhua , the latest test marks a big step forward, achieving a new record when heating the plasma to 120 million degrees Celsius and maintaining it for 101 seconds. In separate experiments, this “artificial sun” heated plasma to 160 million degrees Celsius in 20 seconds. The goal of EAST is to maintain the plasma at 100 million degrees Celsius for more than 1,000 seconds (about 17 minutes). These experiments are not designed to generate conventional electricity, but to advance the field of synthetic physics for next-generation devices such as ITER, the world’s largest nuclear fusion reactor is expected to be. completed by 2025. Similar to EAST, experiments on South Korea’s KSTAR reactor set a world record last year, maintaining plasma at more than 100 million degrees Celsius for 20 seconds. In addition, the country also announced the development of ITER and is expected to officially operate in 2035.

Hydropower dams can negatively impact the environment. More harm than good? Bach Hac Than Hydropower Plant officially stored water when the second bottom outlet closed on April 6. This means that the world’s second largest hydroelectric project has taken an important step towards its power generation goal on July 1. With the discharge door closed, the reservoir water level begins to rise and will reach 775 meters by mid-June. As a result, generation conditions are met. From August to September, the water in the lake will be stored up to 800 meters and then 825 meters in June 2022. The total storage capacity of the Bach Hac Than dam will be 20.627 billion cubic meters, accounting for 91% of the Kim Sa river basin. This is an important part of the Yangtze River flood control system, which has a capacity of 7.5 billion cubic meters. The total installed capacity of this second-ranked power plant in the world is 16 million KW. The capacity of a world-leading unit is 1 million kilowatts. New electricity will help China achieve its carbon neutralization goal. The Bach Hac Than Hydropower Station is an important part of the flood control system in the Yangtze River basin. At the same time, Bach Hac Than is a landmark project in the development of the global hydropower industry. However, while some people give information about clean energy of hydroelectricity, many argue that it can cause immeasurable damage to biodiversity, soil erosion, loss of archaeological and cultural sites. Even more than a million people will have to be relocated. Although the government has yet to reveal a detailed approach to meet the target of achieving carbon neutralization by 2060, hydropower has been featured in the 5-year plan 2021 – 2025 as well as vision 2035. Both were approved by China’s top legislature in March. In those plans, the government stated its intention to “step up the construction of hydroelectric facilities in southwestern China”. At the same time, promote wind energy and solar energy. “The dams will be a solid support to China’s energy industry and reduce carbon emissions. The construction of hydropower plants can bring benefits to irrigation, shipping and power generation, with great socio-economic value, ”said Professor Lu Qiang of Tsinghua University. Lin Boqiang, head of the Xiamen University’s China Energy Policy Research Institute, said the country is set to expand hydroelectric capacity. Because, water is the cheapest clean energy that can be used stably. “The dam construction is still controversial in China because of environmental concerns. However, the objection is no longer as strong as before, because the need to achieve carbon neutralization is increasingly urgent, ”said Mr. Lin. China’s dam construction activity began in the 1950s and has accelerated over the past two decades. At the end of 2018, Chinese hydroelectricity had a capacity of 352GW, accounting for 28% of the total global capacity and more than three times that of any other country. Heavy impact The Bai Hac Than Dam is worth 170 billion yuan ($ 26 billion) on the Jinsha River (Yangtze), in Sichuan province. The dam has made many people admire for the speed of its construction. China only took four years to build, despite the rugged terrain and far away, with the help of artificial intelligence technology. The Bai Hac Than emergency construction reflects the acceleration in China’s plan to expand hydroelectric capacity as a source of renewable energy. By the time Bach Hac Than reaches full capacity by the end of next year, China will be a country with five out of the 10 largest hydroelectric plants in the world. That pace of development has raised concerns about the impact of hydropower dams. China Green Development and Biodiversity Conservation said it is closely monitoring new dam construction projects. “It has been shown that dam construction harms the ecosystem and affects the habitat of wildlife,” said Wang Jing, a spokesman for the organization. We are concerned that some places will increase the development of hydropower projects to serve the government’s goal of carbon neutral ”. According to Fan Xiao, geologist and chief engineer of the Sichuan Department of Geology and Minerals, dams have a negative impact on the local ecological environment. Especially for aquatic animal biodiversity. They slow down the water flow rate and reduce the volume and purity of the water, Fan said. From there, it destroys the habitats of aquatic animals and hinders fish migration. Chinese scientists in 2019 announced the extinction of paddle fish. It is one of the largest freshwater fish in the world. They are also known as Chinese swordfish, with a length of 7 meters. This fish is believed to have gone extinct from 2005 – 2010. The construction of the Cat Chau Ba dam on the Yangtze River since the 1970s has been a major contributor to this species’ decline, researchers found, by preventing fish from reaching their only breeding ground. upstream. According to the scientists, the river system is in trouble containing more than 4,000 aquatic species. However, dam construction, overfishing, water traffic and pollution have caused a lot of damage, with fish stocks declining and biodiversity rapidly declining. Mr. Fan said that building more hydroelectric plants is not the best way to reduce carbon emissions. “Water is a kind of clean energy, but we cannot ignore the huge carbon emissions generated by dam construction, excavation and migration,” warns the expert.

Workers install solar panels at floating power farm. (Image: Reuters) The Thai government is rushing to complete the construction of the floating solar farm in Ubon Ratchathani province, going one step further in promoting the use of clean energy, reducing dependence on fossil fuel source. The project started construction in November 2020, on the surface of the reservoir of the Sirindhorn hydroelectric dam in Ubon Ratchathani province, northeastern region of Thailand. Rated as one of the largest hydro-solar hybrid power generation projects in the world, this solar farm complex consists of seven solar clusters with 144,417 solar panels, built. on an area of ​​water surface up to 121 hectares. In an interview with Reuters news agency, Mr. Chanin Saleechan, Project Manager, said: “It is expected that by the end of April, we will complete the installation of the solar panels and will be ready to connect to the grid. the end of June, 2021 ”. According to the Electricity of Thailand (EGAT), the investment agency that implements the project, this solar farm, when completed, can reach a generating capacity of up to 45 megawatts. Mr. Chanin said that EGAT will adopt an Energy Management System to convert energy sources between solar and hydroelectricity, allowing the hybrid system to produce electricity continuously. He also affirmed that the combination of hydroelectricity and solar power will help reduce the cost of electricity generated. If the pilot project is successful, EGAT plans to continue implementing this model in other hydropower dams across the country over the next 16 years. “When all projects are completed in the hydropower dams, we will reach a total generating capacity of up to 2,725 megawatts,” said Chanin Saleechan. Previously, Thailand’s electricity source used to depend mainly on coal-fired thermal power plants, however, the construction of new thermal power plants is facing a lot of opposition due to health and environmental concerns. . Most recently, two coal-fired thermal power plant construction projects were canceled in 2018. According to the latest Energy Development Plan launched by the Thai government, the country aims to generate electricity from clean energy sources at least 35% of the country’s total electricity production by 2037.

Solar power is being encouraged to use, contributing to creating more clean energy sources, towards the goal of green and sustainable electricity development. Immediately after the Politburo issued Resolution 55-NQ / TW, on February 11, 2020 on the national energy development strategic orientation, the provincial People’s Committee directed the Department of Industry and Trade to coordinate with related agencies and units. research, advise and propose rooftop power development. Department of Industry and Trade proposed the Ministry of Industry and Trade to supplement the planning for 2 solar power plants in Viet Yen and Yen The; solar power projects in industrial zones and clusters with a total capacity of 2,320 MVA. Households in Luc Ngan district install solar power system on the roof. Photo provided by CTV. Mr. Nguyen Duc Hoan, Deputy Director of the Department of Industry and Trade, informed that although power companies stopped connecting and purchased solar power in the case of installation after December 31, 2020, it is only temporary. In general, the State has a mechanism to develop solar power with many attractive policies such as: Buying solar power at high prices, purchasing time lasts 20 years, commercial banks facilitate maximum loans from 70 -80% value of solar power projects in a period of 5-8 years. With the above advantages, many individuals, businesses (DN) and units have been encouraged to take advantage of this energy source. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system with a total installed capacity of 15,936.46 kWp. In which, 10 are enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units. It is known that since 2017, the province has implemented rooftop solar power development programs in a number of different forms, but mainly supported the installation of pilot models, demonstrations for the purpose of evaluation and replication. power saving; At the same time, it will support 10 state agencies to participate in the use of solar power in the near future. At this time, the Department is assigning the Center for Industrial Promotion and Trade Promotion to assist the People’s Committee of Luc Ngan district to install solar bulbs in the district People’s Committee square. The results and orientations of the province show that the development of solar power in the locality is increasing in both quantity and scale, especially in enterprises. This policy, in the immediate future, has brought about a clear effect, contributing to reducing the pressure, saving costs of developing transmission lines and using clean energy sources. Solve the expired solar battery problem The electricity obtained from the sun is clean energy, but when the solar panels expire, they become garbage, which is very dangerous. According to specialized agencies, the average service life of solar panels ranges from 10 to 20 years, depending on the location and the environment where it is installed. However, the handling of expired panels so far has not had a specific direction. A representative of the leadership of the Department of Industry and Trade – a permanent unit to advise on this content, said that in a written consultation with the Provincial People’s Committee on the development of rooftop power projects, the unit has not yet proposed specific measures for Dispose of the panels when the battery expires. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system, total installed capacity was 15,936.46 kWp. In which, 10 enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units “. Mr. Nguyen Duc Hoan, Deputy Director of Department of Industry and Trade Discussing this issue with Mr. Nguyen Ba Trinh, an expert from the Department of Environmental Protection (Department of Natural Resources and Environment), it is known that the solar cell when its expiry date is hazardous waste. The disposal of this waste is very difficult, if not handled properly but burying in the wrong regulations, it will pollute the soil and water environment due to generation of heavy metals or toxic emissions. In the event of a fire the battery is capable of harming human health. There is only one unit in the province, Hoa Binh Industrial Waste Treatment and Recycling Joint Stock Company (Yen Dung) that is eligible to handle this type of waste, but the scale of treatment of the enterprise is small. Mr. Trinh also added that, according to Article 68 of the Law on Environmental Protection, the environmental protection responsibilities of owners of production, business and service establishments must “collect, classify, store, treat and dispose of. disposal of solid waste in accordance with the law ”, that is, the investor is responsible for handling the battery when it expires. Therefore, it may be worrisome that, after the expiration of its use term, households dispose of solar panels with domestic waste, do not hire the unit to collect, transport and dispose of it. Unattended authorities. Or the owner of the panel is not able to handle or dispose of the panel into the environment. Thus, solar power development associated with environmental sustainability has not been paid attention. New authorities focus on planning and encouraging expansion to reduce pressure on the national grid without giving specific solutions to handle solar cells when they expire. Some comments said that the functional agencies, especially the Department of Industry and Trade, the standing unit to advise on this content, should soon offer solutions to handle solar batteries after the expiration of use.
