(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.

Plan from El Salvador Bitcoin mining with volcanic energy?

Status: 10.06.2021 12:45 p.m.

Completely clean, completely renewable: El Salvador’s President Nayib Bukele plans to mine Bitcoins with the help of energy from volcanoes. This is how the country wants to get its high energy consumption under control. El Salvador wants to use geothermal energy from volcanoes for the energy-intensive mining of the crypto currency Bitcoin. President Nayib Bukele tweeted that he had commissioned the state-run geothermal electricity company LaGeo to work out a corresponding plan. The President is convinced that this is very cheap, 100 percent clean and renewable, does not generate any emissions and will develop quickly. There are more than a dozen volcanoes in El Salvador, many of which are still active.

Huge energy requirements

The immensely high energy requirement of Bitcoin mining has been discussed critically in public for a long time. The Cambridge Center for Alternative Finance (CCAF) is working on this topic and has created an index on it . The Cambridge Bitcoin Electricity Consumption Index is supposed to estimate in real time how much electricity is currently being used for mining. The data is then extrapolated to the year. The calculated value is currently around 111 terawatt hours. This corresponds roughly to the annual electricity consumption in the Netherlands. According to the Federal Environment Agency, Germany consumed around 553 terawatt hours in 2020. According to a study by Bank of America, the global Bitcoin industry emits a total of 60 million tons of CO2 annually, which corresponds to the emissions of around nine million cars.

Bitcoin as a means of payment …

A few days ago, Bukele announced that El Salvador would be the first country to introduce Bitcoin as legal tender . He expects the move to create thousands of new jobs in the Central American country. Among other things, taxes should be able to be paid in Bitcoin. Bitcoin is the most popular digital currency. It is not issued by a central bank, but created using a decentralized computer process known as mining. It is by no means clear whether it is even suitable as a means of payment.

… or as an object of speculation?

Because so far, cryptocurrencies have mainly attracted attention as speculative objects, the value of which is subject to extreme fluctuations: Bitcoin was quoted at more than $ 55,000 around May 10, and is currently around $ 36,000. If the value of part of the income is exposed to such strong fluctuations within a very short period of time, this poses a number of problems for a state budget policy. The high volatility of cryptocurrencies is also an incalculable risk for companies. The US electric car maker Tesla, for example, started in March of this year To accept Bitcoin as a means of payment for its vehicles and reversed this step a little later . As a justification, Tesla boss Elon Musk referred to the “insane” energy consumption of prospecting. But it is likely that Musk, as a businessman, at least had these price fluctuations in mind.

Hoang Hieu Trung, Director of Quang Binh PC said, to ensure stable power supply, the unit will continue to invest in completing the power grid, improving power supply capacity to meet the demand for capacity growth of the load. . The company has also assigned 100% of officers and employees to be on duty, to regularly check the system of transmission lines and substations; mobilize vehicles and machinery to promptly handle incidents in the fastest time. Instructing customers to install the EVNCPC CSKH app to monitor electricity consumption. Due to extreme hot weather, the frequency of using air conditioners, cooling devices, and electronic devices for family activities will be more. This leads to the risk of overloading, power failure, even increased risk of fire and explosion, unsafe operation of the power system. Therefore, in order to save electricity costs effectively and ensure enough electricity for socio-economic development, national defense – security and daily life, production and business of people in the province, PC Quang Binh recommends that customers use electricity safely and economically. Specifically, for businesses, PC Quang Binh recommends balancing and arranging production schedules in the direction of reducing electricity use during peak hours, increasing electricity use during off-peak hours; at the same time, enterprises invest in energy-saving production equipment and coordinate with the Electricity sector to monitor and control power quality. “Hot repair” is one of the solutions to minimize the power outage time of customers in hot weather. In addition, Quang Binh PC requires the electricity companies to actively answer customers about problems in calculating electricity bills, and advise people on how to use electricity economically and efficiently. The affiliated units must well control the index recording and index review to promptly detect and handle abnormal cases, avoiding possible errors. In particular, the Company propagates to customers to use tools and utilities of the electricity industry to actively monitor electricity consumption and control high electricity bills in the hot season such as the EVNCPC Customer Service application on devices. mobile phone or a tool to estimate electricity consumption in daily life for electricity users nationwide at website: https://uoctinhdiennang.evn.com.vn/.

The executive of a mobile phone company said that from the perspective of an engineer, the power consumption of the mobile phone will increase after the 5G SA is turned on. Under normal circumstances, the power consumption increases by about 170mA, while some areas (estimated to be areas with poor 5G network coverage) consume The power is increased by 300mA. Such technical terms may be difficult to understand. He directly said that battery life may be reduced by 20%-30%.

The power consumption of 5G mobile phones is too high because 5G mobile phones need to increase 5G radio frequency and 5G antennas. Generally speaking, 5G mobile phones have more antennas than 4G mobile phones, which leads to a significant increase in the power consumption of 5G mobile phones. At the same time, the current 5G network coverage is not perfect. , China’s two 5G networks, each 5G network has only more than 400,000 base stations, while China Mobile built 700,000 4G base stations in 2014, and the coverage of 5G base stations is much smaller than 4G, which leads to the power consumption of 5G mobile phones. Obviously too high.

In order to ensure the endurance of 5G mobile phones, the current 5G mobile phones generally use 4000mAh high-capacity batteries, which also shows that mobile phone companies generally recognize that 5G mobile phones will consume much more power than 4G. However, as an executive of a mobile phone company mentioned above It is said that even a large-capacity battery cannot ensure a better endurance, which is why he suggested that if the endurance is really important, it is recommended to turn off the 5G function.

In fact, since the commercialization of 5G, the problem of serious power consumption of 5G base stations has received widespread attention. In order to ensure the power supply of 5G base stations, even various localities have issued relevant policy support to ensure the construction of power supply infrastructure for 5G base stations. It can also be seen from this that 5G Excessive power consumption of base stations has caused the existing power supply network to be insufficient to support the operation of 5G base stations and have to re-lay the power supply system for 5G base stations.

Subsequently, the three major operators even revealed that electricity bills have soared due to the high power consumption of 5G base stations, and the high cost makes them unaffordable, and they have to shut down 5G base stations during idle periods. Some analysts pointed out that the power consumption of 5G base stations is 3-5 times that of 4G base stations. In addition, the density of 5G base stations far exceeds 4G. If a 5G network covering the whole country is built, the electricity bill will be as high as 200 billion, which will eat up the three major operators. Profit.

This information proves that the power consumption of 5G base stations is terribly large. Nowadays, executives of mobile phone companies have come forward to explain the serious power consumption of 5G mobile phones. It is recommended that users simply turn off the 5G function if they consider battery life. It can be seen that 5G base stations and mobile phones consume power. They are all too outrageous, which makes all parties quite dissatisfied.

Faced with such a situation, it is no wonder that this year’s 5G boom is obviously not as good as last year. In the first four months of this year, operators built less than 30,000 5G base stations per month on average, which is significantly lower than last year’s average of 50,000 per month; and the Chinese market in 2020 Only 308 million mobile phones were sold in China, far lower than the historical peak of nearly 450 million mobile phones. It shows that 5G has not effectively stimulated consumers’ desire to purchase mobile phones. There are actually two 4G mobile phones, namely iPhone11 and Redmi 9A, showing that many users still choose 4G.

Changing habits of saving electricity not only reduces costs for the family but also contributes to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. In addition, customers need to check and maintain the indoor wiring system to ensure reasonable science because if the wiring is confused, it will cause power consumption to be lost in the transmission process; at the same time properly use appliances that consume large electricity such as water heaters, irons, refrigerators, etc. Customer Le Diep Lai in Nguyen Nghiem ward – Quang Ngai city said: “My house has never left the air conditioner below 25 degrees, usually around 26-27 degrees. I find that to be appropriate, not much different from the outside, both protecting health and saving electricity. I also educate my children to turn off electrical appliances in the house when they do not need to use them. Vu Ha Ty customer in Nghia Dung commune – Quang Ngai city only uses the air conditioner when absolutely necessary and usually adjusts the temperature not too low to save energy. Ms. Ty shared: “My house is not located in the center, there are many gaps around, so I often use the wind and natural light in the house, minimizing the use of electricity to operate the cooling equipment. lighting”. Changing the habit of using electricity will save electricity, reduce costs for the family and contribute to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. Currently, customers can use the monthly electricity consumption estimator https://uoctinhdiennang.evn.com.vn to calculate the monthly electricity consumption of the family, thereby adjusting the usage. Use electricity in the most efficient and economical way. Propagate the use of electricity to the people. Huynh Trong Nguyen – Quang Ngai PC Business City recommended: “In addition to daily-life customers, manufacturing enterprises need to review and arrange reasonable production plans, minimizing the simultaneous mobilization of devices. consume large electricity capacity during peak hours and do not leave electrical equipment idle. This is the necessary coordination to ensure the stability of the infrastructure, and to ensure the supply of electricity for production and daily life in the dry season of 2021.”
In addition, to prevent local overload due to high demand for electricity, from the beginning of the second quarter of 2021, PC Quang Ngai also directed its affiliated units to regularly check lines and substations. Thanks to the initiative in the plan and the use of modern equipment such as thermal cameras, flycams, Quang Ngai PC was able to immediately detect and detect abnormal signs occurring with the equipment, preventing problems. can happen.
The economical and efficient use of electricity by customers is also one of the important solutions to help Quang Ngai PCs fight overload, reduce “heat” for the power grid system; thereby contributing to helping PC Quang Ngai perform well the management and operation of the power grid safely and effectively, improving the quality of power supply for customers.

This App is for customers in Hanoi and uses electronic meters to directly send real-time data. Every summer – the peak season for electricity use, many consumers have many doubts and questions about the sudden increase in monthly electricity bills. Now, the information about electricity index and electricity bill of each household will be more transparent than ever, and consumers can also limit their own electricity consumption, all thanks to a tool has just been posted to the app store With the desire to bring a completely new experience with outstanding utilities and features, Hanoi Electricity Corporation (EVNHANOI) has launched a mobile application for customers using electricity. . With just “one touch” right on a smart mobile device, consumers can look up and manage all information about electricity, especially, can actively monitor the daily power consumption index, set threshold of electricity usage warning, self-calculation of electricity bills… Consumers can look up and manage all information about electricity, especially actively monitoring the daily power consumption index. The Covid-19 epidemic broke out again right at the time when the capital Hanoi entered the hot season of 2021, along with that, people’s restriction of going out to prevent and control the epidemic caused the demand for electricity. activity increased. It can be said that at this moment, the newly launched application of the Hanoi Electricity Corporation is one of the “revolutionary” features when electricity users can know exactly every day their family. How much electricity has been used, thereby planning the optimal and more economical use of electricity. With the EVNHANOI App, customers can look up all information about electricity, from the schedule of meter readings, the schedule of power interruption, to being able to send requests and track the progress of electricity services right away. on applications such as new power supply services, electricity purchase and sale contract services (signing, changing, supplementing information,…); services on measuring equipment (testing, testing)… Besides, the EVNHANOI application also helps consumers to monitor the daily and monthly electricity consumption index and compare with the same period in the previous period. In particular, in the “Power consumption” feature, households can also set a warning threshold for electricity use. Simply Select “Warning Output Threshold (kWh)” or “Proportion of power output increased from last month” and the customer can set the desired number (kWh) or rate (%) to be alerted. Thanks to this mobile application, each household will plan to use electricity optimally and more economically. EVNHANOI App not only helps to control electricity consumption, but through two features “Essential power consumption of equipment” and “Billing tool”, consumers can also estimate the monthly cost of electricity. Approximately how much electricity will be used up by the family based on entering information about the quantity, type, frequency of use of electrical appliances in the household in use and checking the family’s electricity bill has the industry. whether the calculation is correct or not. Consumers only need to search for the keyword “EVNHANOI” on the App Store (for iOS operating system) and Google Play (for Android operating system) data stores to be able to download and use the EVNHANOI application right on their devices. smart mobile device.

In order to prepare for the heat wave in 2021, Nghe An Power Company (Nghe An PC) has directed its units to quickly deploy the proposed solutions and scenarios to ensure electricity supply for the whole country. Nghe An province. Nghe An PC workers check outdoor equipment at Hung Hoa Substation (Nghe An) PC Nghe An information, during this year’s hot season in Nghe An, there will be many prolonged heat waves, leading to an increase in the demand for electricity for cooling than in previous years. It is expected that power output will increase, with an estimated capacity of about 820 MW. In order to ensure stable power supply in the face of increasing electricity demand in the summer of 2021, Nghe An PC has prepared a “scenario” carefully, with many solutions to supply electricity to people and businesses. Mr. Le Quang Thanh – Deputy Director of PC Nghe An said that 2021 is not expected to be as hot as the previous year, but despite the prolonged epidemic, most businesses in the area are operating stably again. power consumption is expected to increase. Regarding the load forecast, this year’s output growth will be higher than last year’s at over 12%. The most important and basic solution identified by the unit is to increase the power supply capacity, with the rapid completion of construction of substations and power lines for areas in the province. Accordingly, from the end of 2020 until now, Nghe An PC has built and installed hundreds of large and small projects, including: Raising the capacity of 110kV substation in Cua Lo route, increasing the capacity of 110kV Quynh Luu substation, completing upgrading the transmission line. 110kV from Quynh Luu – Quy Hop. Along with that, renovating and upgrading low-voltage trunk roads; replace the meter periodically; strengthening overhaul, cleaning of transmission lines and transformers; replacing the name plate number of the road, pole number, safety sign of the substation transmission line… and is implementing the plan to energize and put into operation 110kV Con Cuong substation, increasing the capacity of 110kV Hung Nguyen and Quy Hop substations in the month. 6/2021. After energizing, the station will power on in time to serve the people’s demand for electricity in the summer months; support stable and safe power supply in the area. However, according to PC Nghe An, the case of an unexpected increase in output through monitoring is unlikely and in fact, if it happens, the power infrastructure including medium voltage transmission lines, substations and power grids. low voltage will still be able to meet. Alternating power cuts to reduce capacity as announced by EVN will not happen, however, it does not exclude some cases such as: The power supply of the whole system is malfunctioning, incidents such as the breakdown of hydroelectric power units , the North – South 500kV transmission fault leading to failure to mobilize the grid capacity of the whole system will be automatically laid off. In addition, there is a problem of maintenance schedules of power plants (thermal power plants, hydroelectric plants) which can also lead to lack of power, requiring capacity regulation between regions. In the coming period, the vicinity of Nghe An will record a sudden increase in load, especially in Thanh Hoa area, and in Nghe An will also have a sudden increase at the end of 2021 when Hoang Mai 1 and Hoang Mai IPs WHA Industrial Park comes into operation. This is not only a problem for the electricity industry in Nghe An but also for the power system in the North as well as in the whole country. To solve it, EVN will have capacity coordination solutions to meet demand. Power supply scenarios have been developed at the transmission grid level (220kV, 500kV) in order to mobilize and balance capacity in the North – Central – South region. Thus, in the short term, the stable and continuous power supply for Nghe An will be ensured. PC Attention Nghe An Use electricity in hot weather PC Nghe An also noted that, in order for the power grid to operate stably during the peak of heat, it is necessary to coordinate and propagate propaganda at all levels of the government, local and central media agencies on the appropriate use of content. , saving. This content is very important for the national power system and grid, will avoid unnecessary grid overload due to unreasonable use, reduce the greenhouse effect, help limit environmental pollution, have a enough electricity to serve economic development for production and also save living costs for electricity users themselves. PC Nghe An continuously advises customers to avoid being subjective, negligent, not to misunderstand between electricity price and electricity consumption; Use electricity in the most efficient and economical way when entering the hot season. Just small actions from the people such as turning off electrical appliances when not in use, not using many large-capacity devices at the same time, using low-power consumption equipment labeled energy-saving by the Ministry of Industry and Trade. Industry and Trade inspection will help save electricity. PC Nghe An has prepared scenarios for electricity growth in hot weather Families should use air conditioners at a reasonable level of 26-27 degrees Celsius or higher and use fans in combination to reduce power consumption. When using a cold room, do not open the door often, do not use electrical appliances with heat-generating features in the room such as irons, ovens, electric kettles, and hot water heaters. Families have many rooms, when watching TV should focus on watching together, turn off all devices in neighboring rooms. Use electricity only when absolutely necessary, avoid using devices simultaneously during peak hours… For factories, make sure to use the correct capacity and load chart. Along with that, implementing a reasonable production plan, minimizing the mobilization of equipment and machinery with large electricity consumption capacity at peak hours. To minimize electrical equipment operating at no-load, key energy-using establishments must save at least 2% of electricity consumed per product unit per year. Advise customers to use electricity as committed to the electricity industry in terms of registered load and time frame, or reduce capacity when required by the electricity industry due to sudden increase in load… When purchasing new equipment, pay attention to use equipment with energy-saving certification label of the Ministry of Industry and Trade. Responding to the electricity sector, coordinating propaganda and recommending surrounding households to save together.

Over time, gamers and computer users have suffered from a shortage of high-end graphics cards due to the need to buy GPUs from cryptocurrency operators. Now, a new cryptocurrency called Chia will most likely cause similar problems for the storage drive market. According to the South China Morning Post , hard drive prices in China have risen sharply as miners rushed to mine and sell this cryptocurrency. “The price of hard drives keeps going up” Unlike Bitcoin, which consumes a lot of electricity and energy to process complex algorithms, Chia is mined based on a consensus algorithm and is one of the currencies advertised as being environmentally friendly. A Bitcoin mining facility in China. Cryptocurrency Chia aims to reduce environmental impact. Photo: Bloomberg. The founder of Chia is Bram Cohen, who is also a BitTorrent developer. Cohen said he would usurp the outdated industry with increasingly slow and costly documentation capabilities. Although Chia has not been officially traded on the market and only came into operation on May 3, the “miners” have rushed to buy and stock up a series of HDDs and SSDs. According to SCMP, panic purchases can lead to hard drives shortages, high prices and scarcity. On China’s Taobao and JD.com e-commerce platforms, large enterprise hard drives have been sold out. “There have been a lot of people asking to buy a large number of hard drives to exploit Chia in the past few days,” said a customer care worker at the online store Taobao of two major brands Seagate and Western Digital said. Hard drives were sold out on Chinese e-commerce sites. Photo: Weibo. Most business-class hard drives with more than 8TB of storage have already been sold, not sure when new products will be available, the vendor says. According to the manmanbuy.com A Chinese website that evaluates and compares product prices on popular e-commerce platforms, the price of a Western Digital hard drive with 12 TB of storage in February before The increase was 2,188 yuan (about $ 337). On April 8, the corresponding drive price increased to 3,499 yuan ($ 538) on JD.com. Seagate’s hard drive with 8 TB of storage before April 14 cost 1,150 yuan, but has since risen to 2,160 yuan, according to manmanbuy.com . Cryptocurrency miners Chia in China buys bulk hard drives in bulk at the store. In Huaqiangbei, the world’s largest electronics market in southern China, Shenzhen, some vendors said that they now only have a hard drive with less than 4 TB of storage and they don’t know when This situation has just changed. This person also confirmed that the price of a 4 TB hard drive will be a bit higher than the 700 yuan she used to sell before, because the demand from customers is growing. “At peak times, the prices of hard drives will be at least 60% higher than normal. The prices have come down a bit recently, but for now they are still around 50% higher, ”said a supplier named Chen. The topic of hard drive scarcity has become a hot topic, attracting a lot of attention and discussion on Chinese social networking site Sina Weibo, with tags attached to articles such as “rising hard drive prices” and ” Hard drive prices doubled in 10 days. ” “That’s it all, first the graphics card craze, then you guys switch to the hard drive. Now I can only buy one computer case,” said one netizen. on Weibo. Chia’s further goal In recent years, the increasing popularity and demand for computation has increased the value of virtual currencies like Bitcoin. Cryptocurrency mining has become popular and familiar to many people with knowledge of technology and computers. Although the Chinese government does not recognize Bitcoin as a legal currency, the country does not completely ban Bitcoin mining. According to an article recently published in Nature in April, China accounts for about 70% of all Bitcoin mining activities worldwide. Bitcoin mining currently consumes a lot of energy, leading to concerns about overuse of coal-fired electricity. Photo: DW. The increase in electricity consumption related to cryptocurrency mining has also caught the attention of Chinese regulators, as the country is making efforts to save energy and reduce pollution. environment. The leader of Inner Mongolia, the major Bitcoin producing region in northern China due to cheap electricity prices, said they would close all Bitcoin mining pools by May. The global Bitcoin mining network consumes about 113.88 TWh of electricity per year. If ranked as a country, Bitcoin would be the 33rd electricity consumer in the world, out of total consumption by the Netherlands and the Philippines, according to Cambridge’s Bitcoin Electricity Consumption Index.

Workers of Ha Tinh Electricity Company advise on how to save electricity to customers. When the weather is hot, most families use continuously cooling devices such as electric fans and air conditioners. According to director of EVNNPC Customer Care Center Nguyen Trong Phung, air conditioning is the main factor that makes electricity bills soar. Research shows that, during hot weather, due to the continuous use of air conditioners, electricity consumption will increase by 50% -60% on average. Through studies and experiments have shown, when the outdoor temperature increases by 1oC, the electricity consumption of air conditioners increases by 2-3%. The habit of the hotter it is, the more families let the lower room temperature inadvertently make the air conditioner work continuously, leading to increased electricity consumption. To help reduce costs and contribute to stable operation of the power grid, EVNNPC recommends that customers who use electricity need to have the best temperature between 26 and 28 degrees Celsius. In case of not cool enough, users can turn on add a combined blower, which will save about 2-3% energy compared to turning the air conditioner on at a lower heat level. In addition, not regularly cleaning the air conditioner is also a cause of wasted electricity. In addition to the proper use of electrical equipment, EVNNPC recommends that people not simultaneously use large capacity electrical equipment (electric stove, washing machine, heater …) during peak hours (including including the time frame from 11:00 to 14:00 and from 6:00 pm to 11:00 pm daily). EVNNPC will be responsible for checking, handling and satisfactorily responding to all comments and problems of electricity customers in 27 Northern provinces.

Solar power is Qatar’s strength

Huge solar power potential

Qatar and the GCC countries have the highest potential for harnessing solar energy, based on the annual amount of sunshine (including hours of sunshine and solar intensity). Not to mention, July, August and September every year is the time when the whole region has the highest amount of electricity consumption, due to the very high demand for air conditioning and also a strong solar irradiation time most of the year.

Therefore, the development of solar power technology is the most promising energy sector for Qatar. In early 2020, Qatar announced it would build a solar power plant with a peak capacity of 800 MW at Al Kharsaah, comprising 2 million two-sided photovoltaic modules (Bifacial technology) combined with tracking equipment. width over 1,000 hectares. Al-Kharsaah solar power plant will be built on 10km2 near the capital Doha, expected to be completed in 2022.

The Al-Kharsaah Solar Power Plant will reach maximum capacity when solar radiation peaks at noon – the time when the demand for electricity is highest during the day. With a two-sided photovoltaic module system incorporating a monitoring device to align the angle of sunlight absorption, the correlation between solar power production and electricity demand will be strengthened.

Total Energy (France) and Marubeni Trade and Investment (Japan) will sponsor the Al-Kharsaah Solar Power Plant Project, with a total investment of about 500 million USD (ie 0, USD 6 / Wp for Bifacial technology with tracker). This figure shows that the solar energy sector is on a constant and relentless trend of cost reduction. With the use of monitoring devices with a two-sided module, the load factor of a solar power plant can exceed 30% – an exceptionally high level in the solar sector, due to the home load factor. Average solar power in the world is only about 20%.

Fresh water is Qatar’s big problem in climate change

Electricity and water – Two main concerns

Solar PV can play a central role in meeting the growing demand for electricity and water in Qatar, as the two sectors are interrelated (large gas thermal power plants can produce water from desalination). However, the demand for water and electricity in summer is very high: Electricity peaks reach about 8 GW, double the capacity in winter; while the water demand is about 20% higher.

It should be noted, in recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and infrastructure projects. giant. The high level of electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar, suitable for all purposes.

The demand for fresh water in Qatar is growing at a rate of 12% per year, mainly due to industrial development, population growth as well as increased irrigation in the agricultural sector and anti-desertification. Since then, the desalination process has been significantly accelerated, contributing to increased power consumption.

Qatar in the Global Energy Transition Race (Next and Out)

Increase the share of renewable energy

Qatar is implementing a series of measures to reduce greenhouse gas emissions and assert its position as a leader in the development of new technologies.

Domestically, Qatar aims to increase the share of renewable energy in electricity consumption to 20% from 2024. At the same time, the transformation of energy in Qatar is also the realization of the development of public transport systems. new projects, including electric taxis and compressed natural gas (CNG) buses.

Qatar has established official bodies to deal with climate change (for example the National Committee on Climate Change – the national body responsible for climate policy formulation). Moreover, Qatar has participated in the GHG reduction program of the World Bank (WB) and the Global Association for Reducing Gas Emissions (GGFR). More specifically, Qatar Petroleum National Petroleum Company sets a “zero gas emission” goal by 2030. This goal will help develop new insights for other gas producing regions. Qatar Petroleum is promoting carbon capture and storage projects as it sees customers increasingly opting for low-carbon resources.

Qatar will need to make efforts to invest in low-carbon energy technology, by developing goals for energy efficiency and carbon concentration. Thereby, the challenge of Qatar is the reconciliation of new goals in the fight against climate change with the development of the domestic energy sector, along with new and “cleaner” sectors.

In recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and huge infrastructure projects. The high electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar.

Mr. Le Anh Duong – Deputy General Director of Hanoi Electricity Corporation (EVNHANOI) said that economical and efficient use of electricity is an important requirement in the context of a lack of power supply, especially at peak times. summer. Therefore, the propaganda on economical use of electricity has been deployed by the Capital’s electricity industry in many forms, such as through the online customer care system, organizing competitions, on the media … Meanwhile, the electricity industry implements technical plans, such as replacing all mechanical meters with electronic meters, combining daily metering database for each customer group …

Hanoi promotes efficient use of electricity

Specifically, in 2020, Vietnam Electricity (EVN) has built a website http://sudungdien.evn.com.vn, made a list of key energy users (customers with consumption rates). on average 3 million kWh / year or more) to monitor and recommend a reasonable and effective electricity use plan. As a result, in 2020, Hanoi has saved about 430.8 million kWh of electricity, equal to 2.15% of commercial electricity output, equivalent to about 870 billion VND.

In order to effectively implement the use of electricity economically, Ms. Nguyen Thi Thu Phuong – Head of Communication Department of EVNHANOI expressed, currently, the economical use of electricity still depends on consumers’ perception. One of the popular habits of people is not to turn off the lights when leaving the room or unplug the power plug when not in use. In fact, electronic devices, home appliances still consume energy when turned off but not unplugged. “The demand for air conditioning in urban areas is very high. Just each family can save about 10% of their electricity consumption by using equipment that applies new technology (such as inverter technology). the amount of electricity saved is not small, “said Nguyen Thi Thu Phuong.

Dr. Nguyen Quan, former Minister of Science and Technology, Chairman of Vietnam Automation Association, said that about 30% of electricity consumption is for lighting, including civil and public lighting. Saving half of the electricity used for this purpose is equivalent to not having to invest in building a power plant with a capacity of about 4,000 MW.

Focus on key solutions

Promoting electricity-saving solutions not only helps households, agencies and offices reduce costs, but also contributes significantly to ensuring electricity supply. Because now, Vietnam has to import coal for electricity generation and is expected to import liquefied gas by 2023. According to the report of the Ministry of Industry and Trade, with the scenario of an average growth of the gross domestic product of 7% / year, the energy demand by 2025 is 352 billion kWh and by 2035 is 506 billion kWh of electricity; which is equivalent to about 130,000MW of power capacity by 2030. This is a huge challenge facing the energy sector in Vietnam.

Information about the plan to implement the program of economical and efficient use of energy in 2021, Mr. Le Anh Duong said that EVN HANOI is continuing to synchronously implement propaganda measures to each household and operator. main career, production facilities … associated with technical solutions of operation, inspection and supervision. “For households, the electricity industry will coordinate with local authorities, launch the movement “Households save electricity, save energy”, striving for each district to have 500 households, each district has 300 households. typical household use of electricity. Currently, we are coordinating to organize Earth Hour campaign in 2021. This is an annual event that has the meaning of propagating extensively on energy saving.“, Mr. Le Anh Duong specifically stated.

In addition, the People’s Committee of Hanoi has issued the Plan No. 58 / KH-UBND on enhancing electricity saving in Hanoi city by 2021. Accordingly, the city sets a minimum saving target of 2, 2% of total power consumption. The City People’s Committee requires offices, offices, office buildings, schools, hospitals … to save at least 5% of the total power consumption annually. For restaurants, hotels, commercial service establishments, office complexes, apartment buildings, 50% of the capacity of advertising lighting, outdoor decoration must be reduced at night peaks as required by the establishment. local electricity authority …

The City People’s Committee also suggested that households use electricity in an economical and efficient manner, such as: Turn off electrical equipment when leaving the room, cut off the power if not using electrical equipment. The city encourages units and individuals to install rooftop solar power systems, hot water heating systems from solar energy to reduce electricity consumption …

For enterprises manufacturing, construction, the city proposed to give priority to the use of electrical equipment labeled with high efficiency energy; Use off-peak power reserve systems to use during peak hours. In addition, the installation of large-scale renewable energy systems is also a solution to reduce power consumption and even resell the power supply.

In addition, the City People’s Committee will provide technical assistance to the production, manufacturing, renovation and market conversion of vehicles, equipment, machines, production lines, construction works, and mats. public lighting, transportation, energy saving in households …; strengthening capacity for economical and efficient use of energy; Communication to raise public awareness about economical and efficient use of energy.
