“Repowering” New boost for wind power?

Status: 22.06.2021 3:09 p.m.

The expansion of wind power has not progressed as planned for years. Now the grand coalition has agreed on a number of measures that should give the industry a new boost. This week, the new Federal Climate Protection Act should pass the Bundestag and Bundesrat. It stipulates that Germany will become greenhouse gas neutral by 2045 – five years earlier than planned. By 2030, 65 percent of climate-damaging greenhouse gas emissions are to be saved compared to 1990. In order to achieve this goal, along with other measures, renewable energies must also make a major contribution. Wind power is one of them. The planned changes are essentially about making it easier to replace existing wind turbines, known as repowering. The new regulation is intended to facilitate the approval of new windmills at old locations and thus enable repowering that maintains the location. This also applies to wind farms that reach up to 350 meters from residential areas – provided that the loads from the new systems are not higher than the old ones. The aim is to make better use of existing wind sites with more modern system technology, said the politicians Matthias Miersch from the SPD and Stephan Stracke from the CDU.

There is still a lack of space

Lothar Schulze, CEO of the Wind Power Plants Association, maintains that repowering is facilitated “basically makes sense”, but criticizes the unchanged strict requirements for species protection. In addition, there is still a lack of space for new wind farms if the goal set by the federal government of reserving two percent of Germany’s land area for wind farms is to be achieved. Currently 0.9 percent of the area is designated for this, but only 0.5 percent can be used with modern systems. “This means that another 1.5 percent of the federal territory is missing, which means that a giant step has to be taken in the next legislative period”, said Schulze in conversation with tagesschau.de .

SPD parliamentary deputy Miersch also regretted that no agreement had been reached on binding land commitments for wind power. But at least he spoke of one “bridge” in the next legislative period. Green parliamentary group leader Anton Hofreiter criticized that there was only one “a couple of small funding programs” instead of “fundamental reforms”. “Very important and positive” On the other hand, association chief Schulze finds the increase in the tender volume for wind power to four gigawatts agreed for the coming year. However, it is only one “small compensation” the deterioration that has taken place since 2017. In fact, not all tenders were actually implemented between 2017 and 2020. “We would therefore have liked a perspective beyond 2022”, says Schulze. But this task will probably only be taken over by the new government.

Further loosening is necessary

Overall, however, the wind power industry is satisfied with the planned innovations. Material errors and limitations would be corrected. Despite the still too low approval procedures, the quantities were sufficient for 2022 and, due to the catch-up, also in the following years. The next government must, however, continue to promote the expansion of wind energy through further easing, also in the field of species protection, in order to increase the output to 5,000 MW per year, said Association Board Member Schulze.

Nevertheless, the controversial cases in the construction of new wind turbines have steadily increased in recent years. Since 2018, the expansion of wind energy has stagnated at 1,000 to 1,500 MW per year. In addition to the growing resistance from the population, this is also due to the different administrative practices from state to state. The industry also has the impression that new hurdles are always being sought. In the meantime, monument protection has also been included in the approval process for wind turbines. The compromise reached between the Union and the SPD over the past year also caused criticism from the industry Minimum distance from wind turbines to residential buildings . After that, each federal state can now determine which distance is permitted. This can be 1000 meters or less

Improving testing capacity for Covid-19 According to the explanation of Minister Nguyen Thanh Long, this outbreak in Ho Chi Minh City is different from previous times when it was not possible to completely trace all sources of infection. The cause is the appearance of clusters of cases, pathogens can spread and spread quickly, thereby causing potential case misses. Besides, the epidemic in the city has a very fast rate of transmission. When a case is recorded, many people in the family, production line or company have also been infected.

Regarding the orientation in the coming time, the Minister of Health emphasized that improving testing capacity is one of the strategic solutions so that Ho Chi Minh City can quickly control and prevent the disease. Accordingly, Ho Chi Minh City needs to quickly improve testing capacity with a capacity of 500,000 aggregate samples per day, this scenario has been proposed before but needs to be implemented immediately to quickly stop the source of infection. Testing should be carried out in different forms, with key areas, to ensure that all relevant people are tested without omission and repeated testing after 5-7 days. With cases detected through screening, testing or hospital examination, the health sector needs to immediately localize and test the entire area, at the same time implement tracing measures and take samples for testing. In relevant cases, it is possible to apply sample 5 with F1, 10-20 with other cases. For industrial zones, the Minister said that Ho Chi Minh City needs regular screening tests to protect this area against the risk of disease invasion. At the same time, Ho Chi Minh City needs to have a large-scale screening test for the whole city in the form of 1-2 people per household. Minister of Health Nguyen Thanh Long. Photo: Duy Hieu. The Minister emphasized the need to quickly test for antigens, not to leave samples; Strengthening human resources to take samples and perform tests, and at the same time can consider and guide people to take samples for quick testing at home. Medical facilities need to test all patients who come for medical examination and treatment, not only focusing on groups of patients with clinical manifestations such as cough, fever, etc. Minister Nguyen Thanh Long said that the agencies under the Ministry located in the area will be mobilized to support the health sector in Ho Chi Minh City. In which, the University of Medicine and Pharmacy of Ho Chi Minh City mobilizes all students to participate in sampling, the Pasteur Institute of Ho Chi Minh City and other departments will provide maximum support with the coordination of HCMC. Preparing the plan that Ho Chi Minh City has 5,000 cases Minister Nguyen Thanh Long said that Ho Chi Minh City has distanced the whole city according to Directive 15, but the implementation still has many shortcomings.

The Minister recommended that the distance in Ho Chi Minh City should be implemented in different levels, depending on the characteristics of each area, should not rigidly apply Directive 16 throughout the city. Regarding treatment, Ho Chi Minh City needs to be ready for the scenario of 5,000 cases, plan to coordinate the army forces in the area to establish a field hospital; assigned Cho Ray Hospital to be ready for the scenario of setting up an emergency room to receive treatment for serious patients, especially cases requiring intensive intervention such as ECMO. For this scenario, the health sector in Ho Chi Minh City needs to review and prepare medical facilities, equipment and supplies. The Ministry of Health will provide some necessary equipment such as HFLC equipment, ventilators, ECMO to meet the treatment needs of serious patients. With the work of vaccination against Covid-19 vaccine, the Minister suggested that the city health sector should mobilize all efforts to implement the vaccination campaign according to the plan and schedule.

The sugarcane beetle species mainly include the black scarab, the brown beetle and the large brown hairy beetle, which often arise and cause strong damage in sandy soil, riverbank soil, soil with light mechanical composition, or on specialized cultivation areas, growing sugarcane for many years, not rotating crops with other crops. NASU technicians check for insects entering the lamp trap. Photo: NASU. The life cycle of these beetles lasts from 365 to 720 days, going through 4 stages: egg, larva (worm), pupa and adult. Over the years, Nghe An Sugarcane Company Limited (NASU) has researched and applied integrated measures to effectively manage sugarcane beetles in the company’s raw sugarcane areas. This is the result that NASU has studied the management of sugarcane beetles in many countries such as China, Thailand, Indonesia… to apply on NASU’s sugarcane material area. Mr. Nguyen Hoang Son Phong, engineer of NASU said that sugarcane field was damaged by beetle larvae, yield decreased by 13-54%, sugar decreased from 11-57%. The original cane is more severely damaged by beetles than silk cane. Larvae (larvae) hatch from eggs, live in the soil for an average of 240 – 480 days (larvae of the brown hairy beetle are larger, longer than the beetle species) before transitioning to the pupa and adult stage. During the development cycle, larvae are active in the ground, age 1 and 2 in addition to eating cane roots, also eat organic matter, humus, decayed organic fertilizer or bagasse. Light traps are quite simple but effective in killing beetles applied in the cane material area of ​​NASU. Photo: NASU. From the end of the age of 2, the larvae only feed on the roots and underground stems of sugarcane. The 3-year-old larvae have a long sexual development time and cause the most damage to sugarcane, making sugarcane unable to grow, withering, drying and dying, leading to a decrease in sugarcane and sugar yield. The more damage the harvest stage, the more obvious. When the 3-year-old larvae are full, they begin to build cocoons out of soil and pupate to stay in the cocoon. If the weather conditions are favorable, after about 20 days, the pupae will turn into an adult, break the cocoon and crawl to the ground. Unfavorable weather conditions, especially low soil moisture and low temperature, will prolong the pupal development time. This extended period, called the hibernation period, can last up to 4 months. Effective management of beetles According to the research as well as the process applied effectively at NASU, control beetle larvae by plowing the soil thoroughly before planting sugarcane, collecting larvae and spreading the granular insecticide Patox 4GR, with the amount of 40 kg/ha in rows when planting sugarcane.

However, the method of spraying granular pesticides into the soil, in addition to killing larvae, will destroy beneficial microorganisms and insects in the soil, affecting the soil environment. The adults of these sugarcane beetles tend to be strong with light, fly out to mate from March to May, after showers with an amount of over 20mm. This is the best time to kill adults, limit egg laying, and reduce later harm caused by larvae. Mr. Hoang Quoc Tiem, a long-time sugarcane grower in Dua village, Nghia Yen commune (Nghia Dan, Nghe An) said that in the spring crop of 2021, in addition to killing larvae when growing sugarcane, NASU has implemented additional measures to destroy them. maturity such as using lamp traps, casting nets, and making traps in the field. The light trap is designed to be able to install light bulbs from the grid, battery lights or solar power systems. Traps are made by taking advantage of plastic containers, above are lights, below are placed water, add diesel oil to prevent the adults from moving out of the trap. In the middle of the light trap, install 2 corrugated iron sheets of size 40 cm x 60 cm, perpendicular to each other. As adults, beetles are attracted to light, flying into traps will collide with corrugated iron and fall into the water. After the rainy nights of early summer, each light trap catches 250-300 brown beetle adults, 40-50 black beetle adults, and 20-30 large brown-haired clipping adults and lots of adults of other sugarcane borers. The “product” obtained after a night of light traps includes many different species of beetles and borers… Photo: NASU. In addition, on the field, a fishing net is installed, the size of the net is 1cm x 1cm, and the adults move hundreds of fish of all kinds after every night it rains. In the sugarcane field, from 50 – 100m, dig pit traps, measuring 30 cm deep x 60 cm long x 60 cm wide, below the manure and by-products, which are the preferred food of adults, mixed with drugs. Low-odor insecticide is Goldra so that when adults eat it, it will be destroyed. According to the research results of scientists, the female beetle species can lay an average of 229-328 eggs, the lowest hatching rate from eggs to larvae is 70%. With the method of killing adults from light traps and netting in the field, it will limit a lot of harm caused by larvae to sugarcane … Mr. Phan Van Toan, Director of Agricultural Extension of Nghe An Sugar Co., Ltd. said that with the above management method, the rate of damage of beetles on both silk and sugarcane fields is reduced. This is the money for the company to expand the model on the raw material area in the coming years to stabilize the material area and improve production efficiency for farmers.

Causes of body odor Body odor is unique to each person, determined by factors such as age, health, gender, and diet. Body odor occurs when bacteria on the skin break down proteins in sweat into acids that have an unpleasant pungent odor. Causes of unpleasant body odor and sweat (Artwork) The human body has two sweat glands, eccrine and apocrine glands. While the sweat in the eccrine glands only consists of water, salts and minerals, the apocrine glands can secrete oily substances including lipids, proteins, etc. Concentrated in the armpits, groin, hands and feet, apocrine sweat glands are the main cause. Weak body odor. People with hyperhidrosis or teenagers in puberty are susceptible to body odor on hot days. How to get rid of body odor quickly Body odor, if it originates from a pathological cause, can only disappear completely when thoroughly treated. However, some natural remedies can still help eliminate odors in some cases. And in other cases it can still be a good way to reduce unpleasant body odor. Lemon reduces body odor This material is very commonly used in the treatment of body odor caused by increased sweating. At the same time, the citric acid content in lemons can help inhibit and inhibit the activity of fungi or bacteria on the skin. Illustration In particular, lemon works very well when body odor comes from skin folds. The most typical is the armpit, groin or between the fingers and toes. Maintain good personal hygiene Illustration Clean body hygiene is the most necessary measure to reduce body odor on hot days. You need to take a warm bath every day, you can shower more than 1 time if you have to be active and sweat often. Limit hot spicy foods Hot spices such as curry, garlic, chili, onions… can make sweat stronger than usual. Some experts believe that a diet high in red meat can make your body smell less delicious in the summer. Therefore, you should limit eating spicy, hot, greasy foods, add more green vegetables, fruits and drink enough water for sweat glands to work more stably. Use mint to eliminate body odor Illustration If body odor is emanating from the mouth and breath, using mint to deodorize is the perfect therapy. Peppermint has a very high content of methyl essential oil, so it has a good deodorizing ability. At the same time, the micronutrients in this material also help to kill bacteria and have a strong anti-inflammatory. Using green tea helps reduce body odor Green tea contains high levels of tannins and organic acids similar to sage. Thanks to that, it has the effect of slowing down the process of sweating, while inhibiting the growth of bacteria. You can cook green tea water every day to get the best results. Illustration In addition, for women with body odor coming from the private area, this is also an effective solution. Green tea has strong antibacterial properties, so it can help to inhibit as well as kill some pathogenic bacteria in the intimate area. Let’s get acquainted with deodorant roll There are many people who do not have the habit of using deodorant rollers and as a result, the people around them receive enough. To always be a gentleman, get in the habit of using deodorant immediately after showering or whenever you feel sweaty underarms. Illustration Wax or spray-on products are better than water-based products because they don’t leave yellow stains on clothes. -> What happens to the body when drinking ice cold water when coming back from the sun?

Russian President Vladimir Putin. Accordingly, the Kremlin on April 23 said that Russian President Vladimir Putin signed a decree on the application of measures to influence the bad actions of foreign countries. The statement from the Kremlin stated: “Mr. Vladimir Putin signed the decree on the application of response measures to foreign acts of bad will”. Specifically, Russia will limit the number of employees that can be recruited at diplomatic missions of countries that act inadvertent to Russia, the number of which exceeds the Russian government determined will be suspended . For this decree, diplomatic missions, consulates and offices of foreign government organizations acting unfriendly to Russia, Russian citizens or legal entities, will be faced with restricts, or even outright ban on, the use of Russian citizens. The Russian government is expected to identify a list of unfavorable foreign states and then adopt the countermeasures set up under the decree. Reportedly, the move above comes in the context of Russia and Western countries recently repeatedly expelled diplomats in the mutual diplomatic retaliation measures.
