China has no rival in batteries and solar panels. It is already ready to also destroy Western pharmacists

by

China’s quota in the world photovoltaic cell market Broken 80%and for the moment only India seems to have the ability to disturb him in the long term. Its manufacturing capacity is 17 times greater than the rest of the planet togetherwhich has encouraged the Chinese administration to support the manufacture of More than 1,000 GW in N -type cell capacity As the other countries fulfill their net emission commitments. On the other hand, China is also a world leader in The production of lithium batteries. If we stick to electric cars the country led by Xi Jinping Fabrica 57% of batteries that these vehicles use. Catl and Byd are the largest lithium batteries manufacturers on the planet with A market share in 2023 34% and 16% respectively. Its absolute leadership in these two sectors is the result of a strategy that prioritizes investment in R&D and large -scale production to shoot competitiveness. Now Chinese biotechnological companies plan to apply this successful formula to medicines. China has the ability to drastically reduce the cost of medical care “We can reduce the costs of medical care and benefit more people through technological innovation and the improvement of efficiency (…) the recent achievements of China in the field of biotechnology show that it is possible to do it,” says Da Liuthe CR-CP Managing Director Life Science Fund, a risk capital investment group created by the Chinese state and the Thai chain Pokphand Group conglomerate with the purpose of investing in biotechnology companies. “We can reduce medical care costs and benefit more people through technological innovation and efficiency improvement” Chinese pharmaceuticals and biotechnology are living a “Deepseek”. This means simply that the medications they develop are every time most demanded by multinational corporations. What the latter pursue is to obtain the necessary licenses to market, produce or distribute the medications developed in China without elaborating them from scratch. Just three weeks ago the American investment bank Jefferies published a report in which he argues that Chinese companies and assets are extraordinarily competitive thanks to “their efficiency in costs, their small deadlines and the quality of the resulting product.” Interestingly, in seven of the ten main agreements carried out by the global pharmaceutical industry during the first semester of 2025, Chinese licenses were involved, According to the Pharmcube consultant. The success of the Chinese pharmaceutical industry is supported by a strategy very similar to that which has led this Asian country to lead the markets of solar panels and lithium batteries. However, China does not have it as easy as it seems. And it is that the geopolitical tensions that mainly support the countries led by Donald Trump and Xi Jinping are very difficult for Chinese biotechnological companies their international expansion through mergers with foreign companies. According to Liu What they need to transform into great multinational actors in the pharmaceutical industry is to achieve a dominant position in at least one or two fields of biotechnology.

The shadow of solar panels

by

Shared soil use is one of the great controversies that continue to stir in the field: many farmers Do not see with good eyes that crops live together with solar panels. However, More and more studies are and projects They show that agrovoltaic can be a real optimization for the sector. In Álava, Iberdrola wants to try it with apple trees for cider. Short. Iberdrola, in collaboration with the City of Vitoria-Gasteiz, will build a new plant agrovoltaic in Álava. This project will be developed on land assigned by the City Council within the Municipal Program “Vitoria-Gasteiz: Laboratory City”. The agricultural exploitation will be in charge of Kuartángo Sidrería, a reference in agricultural research in the province, whose objective is to boost the local apple production for cider. For its part, the 901 KWen photovoltaic plates installation has been the only agrovoltaic project selected in the Basque Country within the first call for aid to innovative renewable energy and storage projects. Panels between apple trees? As indicated Iberdrolathe project responds to a double need: produce green energy and, at the same time, improve agricultural performance. In this way, panels generate shadow over apple trees, reduce irradiation and thermal stress, protect against adverse weather of climate change, improve soil quality and reduce water consumption. Technical innovations. The installation will have several innovations aimed at optimizing both energy production and crop. An artificial intelligence software, developed by the Basque company Powerful Tree, will adjust at all times the orientation of the plates to ensure the best performance of apple trees. The modules will be located on a porticated structure of 4.1 meters high, which will allow the growth of the trees and the transit of agricultural machinery. In addition, a high -strength steel cable system will be incorporated, designed to reduce maintenance costs. The panels will be 700 W bifacial, capable of capturing solar energy on both sides, and will be accompanied by three investors with a total power of 750 kWn. The set will be completed with a 240 KWN storage system, which will offer a two -hour autonomy. The Italian mirror. The Alava bet is not an isolated experiment. This new project remembers to the Volta winery in the pugliawhich installed 7,770 solar panels in its vineyards. The results were clear: the harvest The results were clear: the harvest was delayed between three and four weeks (improving the quality of the grape), the consumption of irrigation water was reduced by 20 % and a greater balance between acidity and alcoholic degree in the wine was reached, without the need for artificial corrections. In addition, the system reduced the water stress of plants and allowed cultivating unusual varieties in the region. Not only is it agrovoltaic. The formula also works with cattle. In Nueva Wales del Sur (Australia), A study demonstrated That sheepsay of sheep under solar panels improved the quality of wool. The explanation that underlies this situation is because the shadow of the modules allowed animals to have more varied and fresh grass access, while reducing maintenance costs by acting as a “natural corteped.” Many examples, a conclusion. From the puglia to Australia and, now, in Álava, agrovoltaic is much more than an energy technology: it is a model of coexistence between the primary sector and the green transition. And it is not about choosing, as is happening in some cases by The profitability of the land. Between that black and white a third way arises: agrovoltaic. In short, the future of the field does not go on to choose between sun or earth, but to combine them. In the agrarian Spain of 2025 a hectare is no longer measured only in kilos of cereal or liters of oil, but also in kilowatts. And in Álava, apple trees that will soon grow under solar panels could become a symbol of that new balance.

feed solar and wind energy the darkest and colder place in the world

by

In a place where the nights last six months, wind gusts can reach 300 km/hy them the temperatures collapse below the −40 ° C, the idea of using solar and wind energy sounds like a joke. For a few months, however, China is feeding its Antarctica base with renewable energy. How the hell have they done it? Short. Five years ago, electrical engineer Sun Hongbin, today president of the Technological University of Taiyuan, received what seemed an impossible mission: to build a renewable energy system capable of supporting the most extreme conditions of the earth. As he has told Scientific AmericanThe objective was to align the new Qinling Antarctic Station with the green commitments of the Chinese government. The result cost 14 million dollars, was officially inaugurated in early 2025 and is a technological feat that now other countries with Antarctica bases want to imitate. Diesel logistics nightmare. Antarctica stations work almost exclusively with diesel generators, but this dependency has a very high cost. Not only because diesel is expensive, but because transporting it is a logistics nightmare that requires mobilizing breakwinds and military personnel for each replenishment trip, which is usually annual. In addition, environmental risk is huge. The spills are frequent and, in such a fragile ecosystem, where the low temperatures slow down the decomposition, any discharge is a catastrophe. Not to mention the emissions of the combustion itself. The renewables did not endure. The problem of conventional renewable systems is that they do not work in Antarctica. The extreme cold causes the blades of the wind turbines to become brittle, the performance of the solar panels plummeted and the lithium batteries stop working. And that without counting the polar night: six months without seeing the sunlight. Provided to overcome these obstacles, Sun Hongbin did not walk with little ones. His team raised A 2,000 square meters laboratory At the Technological University of Taiyuan that, basically, it was a piece of Antarctica in China. To put to the limit each component, they simulated freezing temperatures, winds of more than 200 km/hyams artificial. How the hell did it. After four years of tests, the team found a robust system that combines wind energy, solar energy, batteries and, the key of everything, hydrogen. The wind turbines have a vertical design reminiscent of an egg blender, which reduces the structural tension and lowers the center of gravity so that the wind does not take them. The solar panels are mounted on a special frame made of reinforced plastic with carbon fiber. This material has a lower thermal conductivity than aluminum, so it does not deform so easily with sudden temperature changes. As for the batteries, instead of the typical lithium ions, they used lithium-ditana. Its internal chemistry facilitates the movement of ions at temperatures below zero. In addition, they put them in a thermal housing that takes advantage of their own residual heat to stay at an optimal temperature. The cake widge. During the polar summer, when there is a sun and spare wind, energy is used to feed an electrolyzer that separates water into oxygen and hydrogen. Hydrogen is stored in high pressure tanks. When winter arrives and the other sources falter, hydrogen is recombine with oxygen in a fuel pile to generate electricity. The only residue? Water and heat, which are recycled to heat the system itself. According to those responsible for the project, the base can work for about 48 hours only with the energy stored in the form of hydrogen. The way to follow. The integrated wind, sun, hydrogen and batteries system has a total capacity of about 230 kW, which It is 60% of the capacity Total Qinling generation. The remaining 40% continues to depend on diesel as support, but the savings is gigantic, so it has received praise from the international scientific community. This is the “first large -scale clean energy system in the world capable of working all year in a polar environment.” And there are already other countries investigating how to adopt it while China maintains its goal of reaching 100% renewable energy.

The Chinese industry has been pulling the prices of solar panels for years. Now 30% of its workers are on the street

by

Chinese solar panel manufacturers achieved a crushing domain of the industry with a relentless recipe: mass production, constant improvements and increasingly low prices. Now that they have left out European and American competitors, The whole world depends on its technology. However, this apparent success story hides an internal crisis with serious consequences: a INSUSTANIBLE PRICE WARmillionaire losses and the silent dismissal of tens of thousands of workers. An unprecedented overproduction. Between 2020 and 2023, the Chinese government redirected huge resources of the real estate sector, then in decline, towards what it called the “three new growth industries”: solar panels, electric cars and batteries. This bet unleashed a fever of new factories and Colossal dimensions solar parks. The result was an unprecedented overproduction. According to Reutersthe world now produces twice as much solar panels it needs, most manufactured in China. This market saturation caused a collapse of prices to the point that many companies They started selling below their costs To give out to the stock, a situation that has been aggravated by the war of tariffs with the United States. The Chinese solar industry lost the amazing figure of 60,000 million dollars last year. The human invoice. The least known consequence of this crisis, despite the fact that companies They asked the government for a rescueIt has been a drastic reduction of personnel. The financial reports of the five largest photovoltaic companies in China (Longi Green Energy, Trina Solar, Jinko Solar, Ja Solar and Tongwei) reveal a 31% reduction of their templates, which means that they left 87,000 employees on the street. This figure is a mixture of direct layoffs and non -renovations due to salary or hours cuts. Diseases are a politically very sensitive issue in China, where employment is seen as the key to social stability. Therefore, none of the big companies have officially announced these massive template reductions. With the exception of Longi, who recognized a 5% cut of the template. Beijing tries to stop the bleeding. The main producers created an entity similar to OPEC to control prices and offer, But it didn’t go well. Before the disaster, the Chinese government took action on the matter. In early July, President Xi Jinping asked for the end of the price war. In addition, a fund of 7,000 million dollars was created to buy and close about a third of the lower quality solar panels in the industry. Is it enough? According to a Jefferies analysis, it would be necessary to eliminate at least one 20-30% capacity manufacturing for companies to be profitable again. However, many Chinese provincial governments, evaluated for their ability to create employment and economic growth, are reluctant to apply drastic cuts that affect their local companies.

China already has a robot that installs 1,000 solar panels per day. It is your weapon to continue dominating renewables

by

The world is converting deserts into photovoltaic oasis. In recent years, we have stepped on the accelerator to achieve ambitious objectives of decarbonization (That the amount of energy consumed by AI are slowing down) And they are being built ‘Solar farms‘Absolutely demential. Many are in Chinacountry that has taken renewables seriously, and to build at the rhythm they needhuman labor is not enough. That’s where robots come into play, and they already have one that places 1,000 panels up to date. Saturn. Sunpure is a company that is dedicated to the integration of robots in the photovoltaic industry. We have already talked about them because the key point of a solar farm is not so much the amount of panels it has, but If these are clean. For example, they have a solar energy fed robot that is responsible for Keep panel ranks clean to optimize your energy generation. But they also have the Saturn. Presented A few weeks ago, this robot has a head that allows to raise a pallet of solar panels and an arm capable of taking those panels and placing them in the rails. Precision. Those responsible claim that it takes less than five seconds to calculate the position in which the panel should go, it fixes it with an accuracy of about five millimeters and the four -meter arm allows to operate with both large panels and very large guide structures. Its autonomy is 72 hours and claim that it is between three and four times more efficient than a human by being able to place between 600 and 1,000 panels per day. He is already working in some solar plants and seeing it in action is a hypnotic: Essential. This integration of robotics into photovoltaic farms is striking, but much less is new or original. In Spain we have Robots-Jardineros that take care of the plants, but we are also installing panels with Sunpure saturn robots similar. In the United States, more of the same. There they have maximum, A robot that also works tirelesslyraising and installing panels of up to 40 kilos in trial fields that, according to its creators, will be essential for the future of world energy. Reason does not lack, since the estimate is that 15,000 solar modules per hour are being installed in the US with a weight of 225,000 tons and the objective is to increase that rhythm by 2035 to 50,000 panels per hour. 24/7. The problem? We want more renewable energies, but there are difficulties in finding labor. That’s where this type of robots come into play. In the United States, 90% of solar energy companies have admitted complications When finding qualified personnel for the installation of these farms. With robots that have autonomy for several days, they work tirelessly thanks to sensors that allow operating in any condition of light and protection against water and dust, humans are relegated to “simple” observers, controlling that the machine does its work correctly. Dominate the market. Beyond having robots, whether the first or not, that China is investing in automating the placement of panels to increase the rhythm, responds to a clear declaration of intentions: that of Continue dominating the market with iron fist. The Asian giant has established itself as the greatest power in green energy, with investments of more than 625,000 million dollars in clean energy in 2024 (three times more than what was invested, and that were very focused on it), and that energy already represents 10% of its GDP. In addition to direct implications, it is something that implies that 90% of the Global Polisilicio Production80% of Lithium batteries and about 70% of the magnets of Rare earthall key both renewable and electric car is under its control. And this huge industrial infrastructure is allowing that China handles very interior prices for technology and has become the great supplier of the world in energy matters. And, in the end, it translates into the fact that it produces so cheap that the rest of the countries buy them instead of competing with their own developments.

An older comet that the sun has invaded the solar system. The old and reliable Hubble telescope already has photos

by

The veteran space telescope Hubble, With 35 years of service behind themcontinues to demonstrate that it is in full form. His last feat has been to capture the first clear image of 3i/Atlas, an interstellar kite that not only comes from outside our solar system, but seems to be older than the sun itself. The interstellar object number three. 3i/Atlas is the third celestial body beyond the solar system that astronomers have detected on our neighborhood, after the mysterious Asteroid 1i/’Oumuamua In 2017 and the Gigantic Comet 2i/Borisov In 2019. The images, taken on July 21 by NASA’s space telescope, offer a detailed first view of the new member of the club. The first alert was given by an astrophysic student nicknamed Astrafoxen In his bluesky profile: “There are many cosmic rays around, but the comet’s comma looks fantastic and bulky.” And indeed, even without processing, the images let a diffuse and active atmosphere intuit around the code core. An unexpected composition. Scientists have already begun to reveal the secrets of the comet. A Preliminary study Based on previous images, he revealed that 3i/Atlas is an active interstellar kite that contains abundant water. However, its cloud of dust looks more like that of type D asteroids: rocks full of silicates with organic molecules, carbon and water ice inside. The composition of the comet’s comma seems to be adjusted 70% to Tagish Lake Meteoritewith the remaining 30% in water ice grains. An older cosmic fossil than the sun. Everything indicates that 3i/Atlas comes from a region of the Milky Way much older than ours. With an estimated age of 7,000 million years, compared to the 4.6 billion years of the solar system, this kite is a time capsule of an era before ours, which especially excites astronomers. First detected on July 1, 2025 by the Atlas poll, the comet has become the priority objective of observatories around the world. One of those who will join the hunt is the Vera C. Rubin Observatory, which with The world’s largest digital camera promises to find many of these invaders.

Spain produces more solar energy than ever, but it only gets a cheap time of electricity a day

by

In full July, with the air conditioning Working tirelessly and The tuned light billin Spain there is a single moment of the day when electricity consumption does not hurt so much in the pocket. That little energy respite is concentrated at noon, a time strip in which electricity costs half or even less than in the rest of the day, but why is it just time? The fire triggered. On Wednesday, July 16, the average price of electricity had been in the € 164.06/MWh at the regulated rate (PVPC), According to data from Electrica de España. For this Thursday 17, a slight drop is expected to € 102.85/MWh, but that half hides an unequal reality: for much of the day, the cost exceeds 120 euros per megavatio hour, As the Iberian energy market operator has collected (OMIE). Only for a single hour there is a “affordable” price. In just seven hours, electricity will go from relatively affordable to almost double its price. At 15:00, it will cost € 73.00/MWh. At 22:00, it will reach € 129.85/MWh. The explanation is not in a peak of consumption, but in a change of source: the sun is exhausted, the gas enters and the market reacts. Why only in that time strip? The reason is in the sun. From three in the afternoon, the solar production curve increases considerably. The electrical system then enters an overoferta phase: there is more renewable generation than real demand. This surplus translates into an abrupt fall in the price in the wholesale market (‘pool’), which reflects in real time the imbalance between what is produced and what is consumed. The problem is that this surplus cannot be stored properly. Spain still does not have batteries No infrastructure sufficient pumping to save That cheap energy and release it when it is most needed. Thus, the system is forced to sell cheap at noon and buy expensive at dusk. To this lack of storage is added a less visible problem: he Curtailment. Although more renewable than ever, part of that energy is lost due to saturation of the network. According to Red Eléctrica, in some knots of the central-south peninsular-such as Arenas de San Juan or Caroyuelas— It has wasted up to 30 % of the electricity generated due to lack of capacity to evacuate it. Meanwhile, the price of light continues to rise. This schedule imbalance generates what experts call a daily “spread”: a price difference that can exceed € 200/MWh between the cheapest time and the most expensive of the day. It is what makes an invoice shoot although part of electricity is generated almost free. It is not just guilt of the sun. The price of light not only depends solely on solar radiation. From the blackout of April 28, Red Electrica has activated A reinforced operational modewith more weight of the combined gas cycles to stabilize the network. This emergency measure It has become the new normality While structural reforms are implemented that will not be ready until next year. The direct impact on the invoice. Consumers with regulated rate (PVPC) are the most exposed to this volatility. Every day, your bill depends on the price hour by time. But even free market customers are noticing uploads: some electrical companies are transferring the contracts to the contracts, As Facua has warnedwhat could be illegal if it is not foreseen contractually. With this panorama, many consumers try to concentrate the use of appliances such as washing machines, ovens or air conditioners during that cheap time of the day. However, not everyone has room to reorganize their life around a single low cost strip. The solution is more than clear. In this environment we have spoken many times: it goes through More energy storage, greater demand management, More local micro -redes and best interconnections with Europe. The government already has launched Royal Decree-Law 7/2025 To accelerate these changes, and has initiated the creation of a capacity market to guarantee the supply. But none of these measures is immediate. Some have deadlines until September, but others will lengthen until mid -2026. Meanwhile, the gas dependence will continue to mark night prices. A race against clock. Every day, the Spanish electrical system offers a single cheap electricity window. It is the reflection of an energy paradox: there has never been so much renewable energy, and it has never been so difficult to take advantage of it efficiently. As long as storage and flexibility deficiencies are not resolved, the cheap time will be a timely privilege and not a guarantee. In a summer marked by heat waves, the cost of not acting on time will be measured not only in euros, but also in emissions, social vulnerability and energy dependence.

We know exactly where and when the longest solar eclipse will occur in history: our great -great grandchildren will see it

by

On July 16, 2186, the Moon will align perfectly between Earth and the Sun, creating an unprecedented eclipse. Unless Millionaire eccentric determined to rejuvenate Be successful, none of us will be here to see it. But our descendants will want to spend that day somewhere in Colombia, Venezuela or Guyana. 7 minutes and 29 seconds. The longest total solar eclipse in history will exceed in almost two seconds the duration of the record until now: the eclipse of June 15 of the year 743 AC, which reached a totality of 7 minutes and 27 seconds on the Indian Ocean, near the current Kenya and Somalia. No eclipse will have lasted so much From before 4000 ACand none will do it until after 8000 AD, so we can be sure that it will be a really unique astronomical event. The total solar eclipse of longer duration in an interval of 12,000 years. The moon will obscure South America. The historical solar eclipse of 7 minutes and 29 seconds will not occur on the mainland: the strip of totality will reach its largest duration over the Atlantic Ocean. However, northern South America will also enjoy extraordinarily long totalities. Especially in Colombia (from Cali to Puerto Ayacucho), Venezuela (from the Orinoco to Imataca) and Guyana (throughout the northern half of the country, including Georgetown). The show will not be limited to that narrow strip. Virtually all South America, including the entire Brazilian territory, can observe a partial eclipse of great magnitude. The eclipse will also be partially visible from Mexico to Paraguay, and west of Africa. In Spain, the Canary Islands will barely touch at sunset. Why it will last so long. The reason for this extreme duration is a “perfect storm” in the positions of the three bodies. The Earth will be at its point farther from the sun (its aphelium), which will make the solar disk look slightly smaller. The Moon, meanwhile, will be at its closest point to Earth (its perigee), so its apparent album will be larger. And finally, the eclipse trajectory will pass very close to Ecuador Earth. This combination maximizes the time that the shadow of the moon takes to sweep the surface of the earth. How we are so sure. Eclipses’ prediction is one of the most successful feats of computational astronomy. The scientists feed their superorders with the current positions and speeds of the Earth and the Moon, and then use Newton’s Movement Laws to know what will happen within several centuries or even millennia. These algorithms are actually models that integrate gravitational equations to project their positions in the future. And they do it with amazing precision, usually with a margin of error of less than one minute over hundreds of years. Primo brother of a recent eclipse. The total solar eclipse of 2186 belongs to the same “lineage” as the great eclipse of North America of April 8, 2024, The Saros 139 cycle. A cycle of Saros is a period of approximately 18 years, 11 days and 8 hours, after which the Sol-Tierra-Luna geometry is repeated almost identically, producing a very similar eclipse but displaced about 120 degrees to the west. The discussions among the eclipses enthusiasts already fantasize about how the hunting of this event will be in 2186. There is talk of flotles of cruises positioned in the Atlantic and flights in hypersonic airplanes to pursue the shadow and further extend the experience of totality. Although we can only imagine it, it is a fascinating reminder of how science allows us to travel in time and be witnesses, at least on paper, of the wonders that the cosmos reserve for future generations.

This loading brows with 192 solar panels and a hybrid system. The most striking thing is that you can do it without crew

by

Covered by 192 solar panels, Blue Marlin It seems more a floating installation than a traditional freighter. But under that futuristic aspect a remarkable advance is hidden: this ship, designed to operate in interior waters, is the first in its class capable of Use sun energy to drive. We do not talk about auxiliary or lighting systems on board: panels feed their electrical propulsion system. And best of all, he is already sailing. The technical advance is not alone in the design: it is in how it moves. The Blue Marlin combines solar energy, batteries and diesel generators in a hybrid system capable of adapting to each section of the trip. Under good light conditions, panels can generate up to 35 kilowatts, enough to feed the propulsion system without external help. At other times, what is known as Peak Shaving: Automatic management that allows reducing the use of generators, activating them only when it really takes. Solar panels and diesel: all that at the service of a specific task Solar energy has already been the protagonist in other maritime proposals: since Cruises that install panels on the balconiesuntil Flexible candles with Perovskitas that promise a new generation of sustainable ships. There were even those who, more than a decade ago, dared to go around the world with him larger solar boat ever built. Blue Marlin has not been created to go around the world or to travel oceans. Its objective is much more concrete: transport steel and bulk by northwestern Germany. These types of routes, which cross interior channels, are key to reducing the use of trucks and emissions in the logistics chain. By incorporating electric propulsion, they affirm, Blue Marlin allows you to reduce until 36,000 kilos of CO2 a yeara figure nothing smaller for a single ship. In addition to its hybrid propulsion system, the Blue Marlin incorporates a second relevant innovation: remote navigation. Thanks to Seafar technology, the ship can operate without crew on board in certain stretches of the journey. After overcoming the evidence, the German authorities They have authorized that Blue Marlin Navigate telecontrolled between Salzgitter and Friedrichsfeld. This not only reduces operational costs, it also opens the door to a new logistics model in which part of the control can be done from the ground. One of the biggest challenges of river transport is to maintain operability when water level drops. Blue Marlin has been built with that problem in mind. Your helmet has been designed to guarantee stability and maneuverability With a draft of only 1.10 meters. Thanks to its veth helm propellers and an additional bow propeller, it can maneuver precisely even in complex sections. This capacity makes it a robust tool for an increasingly unpredictable environment. Behind the Blue Marlin there are two key actors: HGK Shipping, that moves 43 million tons per year in Europeand Salzgitter Agresponsible for one of the largest steel productions on the continent. Together they have developed a freighter that not only fulfills a logistics function, but also symbolizes a change of course. The construction has been carried out in several phases and countries, with very demanding standards.

If Europe is beating solar energy records this summer, why has the price of light shot?

by

Summer is a paradox season for the energy sector. On the one hand, renewables are reaching historical figures. June marked the month of greater production of solar energy ever registered in the European Union: Friolera of 45 twh22% more than the previous year. On the other, many Europeans saw how their light of the light doubled or even tripled. The question is inevitable: if we swim in solar energy, why do we pay more for electricity? The demand is triggered. The heat waves that run Europe They have put the thermometers around 40 ºC in numerous points in Spain, France and Germany. With air conditioning systems, working at maximum power, the electrical demand has shot. According to him Last Ember reportdaily demand grew by 14% in Spain, 9% in France and 6% in Germany during the month of June. A greater electrical demand, alone, already presses the prices of upward light. But the heat brought with it a second problem, this time on the offer side. Thermal plants are suffocated. The same heat that drives the demand for air conditioning puts traditional energy plants, especially nuclear. These facilities need huge amounts of river water to refrigerate their reactors. When the water temperature rises too much, its refrigeration capacity decreases, forcing to reduce production and, in extreme cases, to stop it completely. France It has been the most affected country. Its fleet of nuclear centrals, one of the pillars of the European interconnected network, is suffering capacity reductions in almost all its facilities. But it is not an exclusively nuclear problem. In Poland, the cooling of coal centrals is being a constant concern, and in Italy, the overheating of the network cables was the most likely cause of the blackout of July 1. At the time of maximum need, a crucial part of the generation of traditional energy is not available. Missing storage for the solar. The saving of this crisis is photovoltaic solar energy. In Germany, the Solar came to generate 50 GW peaks, covering between 33% and 39% of the entire electricity of the country. With a marginal cost close to zero, solar panels are doing exactly what is expected of them: maintain the stability of the network during the day with abundant and cheap energy, despite their Performance problems under extreme heat. The night is another song. At sunset, solar production falls to zero, but the refrigeration demand remains high. When the high temperatures persist until well into the night, Insufficient storage capacity (either in batteries or With pumping hydroelectric) forces to resort to gas and other fossil sources to cover the hole, shooting prices. The damn “Spred”. This temporal mismatch caused by the abundance of variable energy and the lack of resources to store it is what causes madness in prices. A daily price differential (the “spred”) of up to € 400/MWh in Germany and € 470/MWh in Poland. This night peak, and not the average price, is what triggers the final bill and makes the light through the clouds when more cheap energy is producing. The lesson is clear: the challenge is not only to generate cheap renewable energy, but manage it. More storage is needed to buy energy at low prices at noon and sell it at high prices in the afternoon. But also More European interconnections. The heat wave did not affect all of Europe with the same intensity and the same day. The biggest June peaks arrived in Madrid on Domingo, Paris on Tuesday and Berlin on Wednesday. The reinforcement of the interconnections will allow to distribute the cheap energy more and better.
