Tesla’s solar roof was going to revolutionize this segment. Ten years later it pivots to manufacture lifelong solar panels

by

A decade ago Elon Musk seemed capable of anything, and many of us believed that had another revolution in his hand with Solar Roofthe Tesla solar roof that revolutionized conventional installations to camouflage them with the roofs of our houses. Their goal was to install 1,000 of these solar roofs every week by the end of 2019. The reality: there are about 3,000 solar roofs in total, and the company has decided to pivot to survive. Now it is a much more conventional company that may achieve the success that its original version never came close to. Promises and realities. The deployment of the “solar roof” proposed by the Tesla subsidiary It has been an operational failure. In 2016, the promises of performance combined with sustainable design and architecture (tempered glass tiles that generated light) were very striking. Ten years later, the product represents a residual fraction of Tesla Energy’s income, and the company has decided to surrender to the evidence. They will do what others were already doing: manufacture traditional solar panels mounted on existing roofs. Complex installation. Tesla’s big mistake was not in the panels themselves, but in the physics of the construction itself. A conventional roof is installed in a couple of days, but the Solar Roof required weeks of work for an ultra-skilled workforce. Being made up of hundreds or thousands of small individual tiles, installers had to make multiple electrical connections in an environment exposed to environmental conditions. Costs skyrocketed. Thus, a single failure could render an entire section unusable, and to make everything perfect the installation costs were high: about $106,000 before incentives, when putting solar panels on a conventional roof costs about $50,000 less. Payback is achieved in about 15-25 years, compared to 7-12 for conventional panels. In a lawsuit from several clients was revealed that in some cases the price of the installation ranged from 72,000 to 146,000 dollars. Difficulties everywhere. These types of projects proved to have many obstacles. For example, the different geometries of the roofs or their shadows. There was also the fact that Tesla tried to control the entire installation process with its own personnel, but labor shortages were a bottleneck that delayed deliveries. A reasonable (but late) decision. In early 2026 Tesla launched its new solar panel, the TSP-420which makes use of a new optimization system based on 18 energy zones. Among other things, this panel solves a problem that affected the inverter architecture of Solar Roof panels. It is a much more reasonable strategy, especially since it is much more profitable and faster to install a standard panel on a roof than to do so with Solar Roof’s original proposal. It is curious that the power generation business has not worked out for him, but yes do it that of storage with their Powerwall. Musk once again promises the (perhaps) impossible. At the Davos conference, Elon Musk announced that Tesla had as its objective create 100 GW per year of solar panel manufacturing capacity in the United States. For this purpose, the purchase of solar panels and cells is proposed. worth 2.9 billion dollars to the Chinese company Suzhou Maxwell Technologies. Too many promises. The goal seems once again exaggerated. Global solar installations in the United States in 2023 reached 32 GW, and Musk aims to reach 100 GW by the end of 2028. He would have to triple the total installed capacity that there was three years ago, and do it at a frenetic pace without any problems. We have heard this story before. The challenge seems too colossal even for the tycoon, and reminds us of the promise that he himself made in 2016. It was then that he assured that his solar roof would end up costing less than conventional roofs with traditional solar panels. He also said that the SolarCity Solar Gigafactory would produce 10 GW per year. Neither of those two promises came true.

The longest solar burst ever detected lasted almost three weeks. Four ships had to join forces to study it

by

Four different spacecraft have confirmed the detection of the longest solar burst ever recorded. measured to date. Previously, the longest known lasted 5 days. However, the one just described in a studio in The Astrophysical Journal Letter It was much longer, as it lasted from August 21 to September 9, 2025. No more and no less than 19 days. Four ships, one answer. This very special solar burst was detected for the first time by Solar Orbiter of the European Space Agency (ESA). The objective of this spacecraft is none other than to study the poles and solar winds, as well as the Sun’s magnetic field, from a close distance. It was not the first solar burst that he had detected, but he had never encountered one of these characteristics. The results were confirmed twelve days later by the ships wind and Parker Solar Probeboth from NASA. A few days later, the STEREO-Aalso from NASA, again supported the same result. A type IV burst. This long burst is a type IV burst. A phenomenon that occurs when electrons are trapped in the Sun’s magnetic field is known as a solar flare, so that they begin to spiral around its lines, generating a large amount of electromagnetic radiation. There are five types. Those of type IV They have wide bandwidths and can last for hours. The duration of this was much longer, which is why it attracted so much attention. The key is in coronal mass ejections. Solar flares are completely harmless. And, unlike other phenomena, such as solar winds or coronal mass ejections, they do not release plasma or charged particles, only radio waves. Therefore, they would not affect telecommunications on Earth. Now, in this case it has been seen that the burst could be related to coronal mass ejections. According to the clues collected by STEREO-A and the scientists’ reconstructions, there must have been 3 coronal mass ejections that served as food for the radio burst. But what is that? Coronal mass ejections are abrupt releases of plasma that are generated in the solar corona when a lot of energy accumulates in it. Possibly, these three ejections were supplying electrons to the explosion, such that there were always electrons trapped and rotating around the magnetic field. That, possibly, is what made this burst last so long. When he was running out of “food”, the Sun was giving him more. Very important. These types of findings are very important because they help us better understand how the Sun works. Solar activity follows cycles of approximately 11 years, with peaks and low points. In 2025 there was a big peak, especially active. Studying everything that happened at that time is very useful to better understand this type of phenomena, especially those that can affect telecommunications, such as solar winds or coronal mass ejections themselves. In this case, the ejecta had not been seen as such, but the long trail they left had been seen. Analyzing that footprint is as useful as it is for paleontologists to study those left by the dinosaurs.

is outshining solar panels

The world has returned to coal. NoWe are not in the 18th century. in the midst of the Industrial Revolution, but in the era of artificial intelligence and wild computing in huge data centers. Although it seems that a large part of the GPUs mounted in data centers are stops most of the timewhen they start working they need a huge amount of immediate energy. There renewable energies cannot respond (due to intermittency and storage), and that is why Big Tech is resorting to opening nuclear power plantsof gas and, of course, coal. And the big problem with coal is not only the issue of emissions, but something almost as serious: its pollution. is interfering with solar energy production. It neither eats nor lets eat, as they say, and the researchers who have measured it point out that reality can be much more negative than what they reflect in their study. Double contamination Researchers from the University of Oxford and University College London have just published in Nature a study in which they detail how they have mapped and analyzed more than 140,000 photovoltaic installations around the world using satellite images. After comparing it with atmospheric data on air pollution and calculating how much sunlight stops reaching the photovoltaic cells due to that pollution, they concluded that these solar ‘farms’ produced 5.8% less than they could have produced. Although the study has been published now, the data corresponds to 2023 and, to lower that figure of 5.8% a little, they point out that it is equivalent to 111 TWh of lost energy. How much is that? The amount generated by 18 medium-sized coal-fired power plants. That the figures are from 2023 is interesting. Electricity from solar energy was already well established and, furthermore, we were talking about the end of coal. The huge data centers they needed all that immediate energy They were not yet as developed as they are now and both the energy companies and the countries themselves were leaving this type of energy generation aside. However, there was something that the researchers say had not been measured: the brake on that transition to clean energy. Between 2017 and 2023 there was an explosion in the installation of solar panels with an average of 246 TWh new each year, but this study points out that the losses caused by aerosols were about 74 TWh. That is, almost a third of what was earned by installing plates was lost due to particles emitted by coal plants. China or India stop generating a lot, but there are countries that are directly negative, such as the United Arab Emirates, South Korea, Greece or Pakistan. These particles are extremely fine, but they are still capable of absorbing light before it reaches the solar panels. It’s like an invisible umbrella that prevents photovoltaic installations from deploying their full potential and the curious thing is that the countries that have accelerated the most with photovoltaics are those that burned the most coal, so they were tripping themselves up. Focused on China, the great solar power in the worldit is estimated that in 2023 it will generate 793.5 TWh of electricity thanks to photovoltaics. This was 41.5% of the world total, but at the same time had the largest loss due to these particles, with production that could have been 7.7% higher. And the researchers point out that 29% of those solar losses were directly related to emissions from coal plants. However, they have also found that China is the only powerful region in electricity production through photovoltaics that has been improving over time due to some strict emission standards. In the United States, although photovoltaics have also been on the rise, solar production fell by 3.1% during the same period due to the same thing: large photovoltaic ‘farms’ are too close to coal plants. The team points out that it is no longer just that pollution blocks sunlight, but “it also changes clouds, which can further reduce solar energy production. This implies that the real impact is likely to be greater than what we have measured, so we may be overestimating how much solar energy can contribute to emissions reductions if we do not control pollution from coal energy.” That is to say, although more renewable sources are being installed, with solar being the star in much of the world (in Nordic countries it is wind), it is likely that this overestimation of renewable production serves to make governments and companies take advantage, but it should be taken into account. the hidden carbon brake to banish fossil fuels from energy generation once and for all. The problem is what is surely on your mind. These figures correspond to the period measured in 2023, but since then we have experienced a significant increase in data centers. As we say, they need a huge amount of electricity available immediately to supply the consumption of the facilities in computing peaks, and this is something that they are not covering with renewables. To do this, data centers they would need huge batteriesbut they would exhaust the energy quickly and would go back to ‘pulling’ from conventional sources. Since the explosion of data centers, some have relaxed anti-pollution measures and even the oil companieswho were making the transition to renewables, they swerved to redirect their gaze to a much more profitable business in the short term. And the most important thing is what we also mentioned: it doesn’t matter if you install many solar panels if you increase the rate of coal production to satisfy the gluttonous data centers because it is no longer just that there is direct pollution, but that those particles resulting from the burning of coal are interfering with the production of solar energy.

The Solar Impulse made the dream of the solar airplane a reality. Now it has ended up destroyed after an accident

by

There was a time when the Solar Impulse 2 It seemed like it came from a simple question: how far can a plane go if we leave out conventional fuel. The answer was not a commercial product, but an experimental aircraft powered by solar energy and batteries that ended up flying around the world. That is why the news has a special charge. That plane that symbolized a different way of imagining aviation has ended crashed in the Gulf of Mexico during an autonomous test. The coup came on May 4. According to Aviation Safety Networkthe Solar Impulse 2 was conducting an autonomous test flight when it lost power and ended up crashing into the water. The least bitter part of the news is that there were no injuries or deaths, something important because the plane was already flying without a crew in this new stage. The most symbolic part is another: the device that for years turned a technological promise into something visible has been reduced to the remains of an accident. Behind the project was Bertrand Piccarda figure marked by a family tradition of explorers: his grandfather Auguste Piccard was a pioneer of the depths and his father, Jacques Piccardarrived at the Mariana Trench. In 2003 started to imagine a solar aircraft capable of going around the world to draw attention to the “sustainable energy“First came Solar Impulse 1, with its initial flight in 2009and then the final jump. The plane that converted the sun into flight energy What is striking is that this ambition was not based on a gigantic machine in the traditional sense. The Solar Impulse 2 had a huge wingspanabout 71 meters, higher than that of a Boeing 747, but it weighed around 2.3 tons thanks to its carbon fiber structure. The energy came from 17,248 photovoltaic cells distributed throughout the plane, with a maximum power of 66 kW to drive four electric motors and charge four lithium-ion batteries. The moment that made it more than a technological oddity came in 2016. That year, the Solar Impulse 2 completed the first trip around the world of a fixed-wing plane powered entirely by solar energy, a journey that It lasted for more than 15 months. Bertrand Piccard and André Borschberg, co-founder of the foundation, alternated at the controls during the tour. It was not a demonstration of speed, of course: the plane was moving between 31 and 62 miles per hour, slowing down during the night sections. After that feat, the story changed tone. In 2019, the Solar Impulse Foundation announced the sale of the plane to Skydweller Aero for an undisclosed amount. The Spanish-American company did not view the project from exactly the same place as its creators: its interest was in exploring the potential of the aircraft as a surveillance and communications platform, a very different destination from the original message of energy awareness. With Skydweller the technical transformation of the device also began. After incorporating numerous modifications, the plane completed in Spain his first autonomous flight in 2023and the following year it carried out its first completely unmanned operation at Stennis International Airport, near Bay St. Louis, Mississippi. The company’s stated goal was to develop a fleet of solar aircraft capable of non-stop flights at certain latitudes, between Miami and Rio de Janeiro. The ambition was evident: almost continuous operations for military and commercial contracts, at a much lower cost than satellite-based options. A huge promise that has ended underwater.

solar panels that do not compete with the earth, but rather protect it

by

In the vast regions of northern Mexico, where the sun beats down with relentless intensity and water is an increasingly scarce and coveted resource, a quiet revolution is brewing. The growing demand for food, the scarcity of water and the urgency of moving towards clean energies force us to rethink how we manage our resources. In this scenario, a technology emerges that seems to challenge the traditional logic of competition for land: agrivoltaics. Far from choosing between growing food or harvesting light, agrivoltaics strategically combines agricultural production and solar energy generation on the same surface. By installing solar panels elevated above the crops, space is dually used without interrupting agricultural activities. A concept that comes from Germany. This idea, which began to germinate in Germany in the eightiesmanaged to land as a real option in Mexico thanks to the historic collapse in the prices of solar panels during the last decade, which transformed this vision into a financially viable alternative for countries with our climatic characteristics. In the year 2023, The Mexican Agrovoltaic Network (RAMe) is bornan initiative that, according to its own mission statement, seeks to analyze, disseminate and promote these projects by integrating specialists from multiple disciplines. Today, RAMe brings together more than 70 organizations—including universities, companies and rural communities—with a presence in at least 14 states in the country. The urgency to optimize the territory. According to data revealed in Intersolar Mexico 2026For this year alone, conventional photovoltaic developments have been authorized that will devour around 5,000 hectares of land. This shows a voracious need for space for electricity generation that, if not managed properly, could displace primary activities. “Agrivoltaics comprehensively addresses three critical challenges for the country: energy security, water security and food security,” explained Valeria Amezcuapresident of the RAMe. Water is crucial. In Mexico, the agricultural sector consumes about 76% of the available fresh water. This is where solar panels they do their magic: they act as technological umbrellas that moderate high temperatures and protect crops from intense solar radiation. This drastically reduces plant evapotranspiration, helps conserve soil moisture and reduces water demand. The potential for the country is massive. If we look to the southeast, in the Yucatan Peninsula —where electricity consumption is growing above the national average— the data is revealing: Using just between 1% and 2% of the region’s livestock territory would allow for the installation of up to 12,000 MW of solar capacity. Current energy needs would be covered without the need to cut down a single hectare of forest or sacrifice the livestock vocation of the land. lThe challenges from the field to the law. However, bringing the theory to the field involves technical and economic challenges. photovoltaic structures must be modified and installed at a higher height (up to two meters) to allow the passage of tractors and the natural growth of plants. This adaptation increases installation costs between 50% and 100%. Despite the cost barrier, the evidence in the field is promising, since there are successful tests with lettuce, tomato, carrot and chiltepin pepper crops. In addition, RAMe is leading projects with high social impact, such as collaboration with Otomi communities in the State of Mexico, installing panels on greenhouses to generate clean energy that powers drip irrigation systems, saving up to 80% of water. The academic effort in Mexico City with the Sustainable and Educational Agrovoltaic Plot (PASE) also stands out. promoted by UNAM. However, the biggest current brake is bureaucratic. In Mexico, agrivoltaics lacks its own legal figure. Producers and developers face a regulatory labyrinth where they are required to process the same permits as a large-scale power plant, even though the land maintains its original agricultural vocation. This contrasts with countries like Italy, that have already been adapted its legislation to facilitate this dual model. htowards the circular economy. For the model to be truly revolutionary, it is not enough to generate shade and electricity; We must also look towards the earth. The magazine of the National Solar Energy Association (ANES) puts an innovative proposal on the table: integrate solar pyrolysis to manage agricultural waste (stems, stubble, leaves) left after harvest. Solar pyrolysis is a process where biomass decomposes at high temperatures (between 400 and 800 °C) limiting oxygen. Unlike conventional methods, this uses a solar oven (composed of a heliostat and a parabolic concentrator) as a source of pure heat, eliminating the use of fossil fuels. With this you obtain biochar (biochar), a highly stable and porous material that remains in the soil for decades. This biochar is an excellent improver that increases soil fertility, optimizes water retention and sequesters carbon from the atmosphere, becoming the perfect ally against climate change and replacing chemical fertilizers. A call to action. The circular agrovoltaic model, anchored in the vital nexus of Water-Energy-Food, is much more than an engineering curiosity. But as the RAMe warnsthere is a latent risk: that the energy transition is purely technological and forgets the people. Changing the origin of electrons from fossil to solar is of little use if it does not improve the quality of life and the economy of peasant families. The development of this sector will inevitably require effective public policies, strategic investment and genuine collaboration between the agricultural, energy and academic sectors. Agrivoltaics is not only a technical alternative to meet clean generation quotas; is an imperative call to action to build a more resilient and equitable future. Mexico has the sun, it has the land and it has the urgency; Now all that is missing is the will to awaken this sleeping giant.

Aragón is one of the autonomous communities of “energy Spain” and its capital is positioning itself as one of the leading European cities in the urban energy transition. Within your strategy “Zaragoza Smart and Climate Neutral City“, the capital of the Ebro has just start the works to increase its photovoltaic park within the city without altering the available space for other infrastructure. As? Installing photovoltaic canopies in four public parking lots. Parking lots converted into solar parks. The facilities are distributed in four locations: the Miguel Servet parking lots (780.64 kWp), Pignatelli (460.53 kWp), Parque de Oriente (963.9 kWp) and the Macanaz discretionary bus parking lot (279.65 kWp), reaching a total installed power of 2,484.72 kWp. In total, there will be 4,176 solar modules to cover 10,816 square meters of canopies and will produce 3,638.5 MWh per year, which is approximately equivalent to the consumption of a thousand average homes. according to city council data. The structures are not simple panel supports, but canopies designed to integrate into current urban aesthetics, so that they offer shade and protection to vehicles. In addition, of the 651 spaces that will be protected under a photovoltaic cover, 40 will incorporate charging points for electric vehicles. Why is it important. As explains the Renewable Foundationthe parking lots – photovoltaic parks are three in one: they provide shade for vehicles, provide “clean” electricity to electric car charging points and also make energy from renewable sources available for self-consumption or supply. The third point is especially interesting: there will be homes close to the parking lots (within a 5 km radius) that will be able to benefit from this energy without having to install panels in their buildings and all that this entails in terms of investment or bureaucracy. Furthermore, consuming energy where it is produced minimizes transportation and distribution losses. At an institutional level, the council will reduce its energy bill and advance its climate neutrality objectives for 2030. Architecturally, the relevance of this project lies in the efficiency of land use, since it uses existing infrastructure that is already sealed by asphalt, which prevents the degradation of natural or agricultural land. Context. The project is part of the European Commission’s mission of “100 Smart and Climate Neutral Cities by 2030” of which Zaragoza is a member, which forces the capital city to accelerate its energy efficiency and sustainable mobility policies. Zaragoza already has successful solar projects under its belt, such as host the first “solar neighborhood”“of the Spanish state. On the other hand, the Spanish regulatory framework (Royal Decree 244/2019) has facilitated the expansion of collective self-consumption through a simplified compensation mechanism for the energy produced and not consumed instantly by small self-consumers, which makes it technically and legally viable that, for example, the solar parking in Macanaz can provide energy to nearby schools or homes. The regulations allow an installation of up to 5 MW with consumption points up to 5 km away, which gives more breadth and flexibility. This legal certainty has allowed Zaragoza to be one of the most ambitious cities in the deployment of urban photovoltaics in Spain. chow they do it. Through a public-private collaboration where the city only provides the land. The project was awarded in January 2025 to Repsolwhich executes it through Solar360, a joint venture of the energy company and Telefónica Spain specialized in photovoltaic self-consumption. The investment is 5.66 million euros and is borne by the company: the City Council does not pay anything for the installation or maintenance. In exchange, Repsol operates the service for 25 years and pays the council a fixed fee of 6,000 euros per year for each of the four parking lots, plus a percentage of the energy generated in kind: 10% in three of the lots and 4% in the fourth. Yes, but. The work requires the felling of about 38 trees in the first two lots, which will be compensated with 55 new 16/18 caliber trees (not a seedling, but not an adult tree either) and a contribution of 23,990 euros. The problem is that they do not replace an adult tree and its functions (shade, water regulation, minimizing the heat island effect), something for which they will need decades. On the other hand, according to the Renewable Foundationthis type of installation is amortized over a period of four to eight years. With a 25-year concession, Repsol will recover its investment in less than a third of the period granted, which raises reasonable questions about whether the fee received by the City Council is proportional to the profit the company obtains. When the project is operational and we know real production data and participating homes, we will know the answer.

In 2014 it was inaugurated as the largest solar thermal power plant in the world. 12 years later they want to close it after incinerating birds

by

The huge Ivanpah solar thermal power plant, opened in 2014 in the Mojave Desert, was almost closed after just 11 years of operation. An end accelerated by its history of technical, economic and environmental problems that, however, was paralyzed in January of this year after the agreement of all those involved. Context. Concentrated solar thermal energy, once considered one of the most cutting-edge technologies for clean electricity generation, is not going through its best moment. Especially in Nevada, where the Crescent Dunes fiasco was already very public. The concentrating solar thermal system uses thousands of mirrors, or “heliostats”, that follow the path of the sun to concentrate its light on central towers. In these towers, the extreme heat is used to heat water and produce steam, which drives turbines connected to electrical generators. The Ivanpah case. The Ivanpah plant was built with an investment of $1.6 billion in loans from the U.S. Department of Energy and long-term contracts from major electric companies. It was the largest solar thermal power plant in the world until the inauguration of Port Augusta in Australia. 11 years after its inauguration, the enormous solar thermal plant began to close after failing to meet its initial expectations. The lack of profitability condemned it, at least a priori. A succession of rulings and complaints from environmental groups about its impact on wildlife accelerated its end, approved by the US Department of Energy. Continuity. However, the decision was reversed in January 2026 by the California Public Utilities Commission (CPUC). Ivanpah will remain open. Their argument is that uncertainty in federal renewable energy policies forces us to prioritize the reliability of the current electricity supply. In addition, the commission seeks to prevent the enormous investment in infrastructure already made from being lost, despite the high operating costs and the serious environmental impact on local fauna. The measure ignores the previous agreement between the companies to close the plant and save money for users. A priori, it will remain open until its contract expires in 2039. A complex technology. One of the main problems has been the difficulty of keeping the mirrors precisely aligned. The technology, which requires exact tracking of the sun, has proven to be unstable and unreliable in practice, says a CNN report. The maintenance of the complex mechanisms and the management of the turbines in turn generate high operating costs, which has caused concentrated solar thermal to lose competitiveness compared to other renewable technologies, especially photovoltaic solar, whose prices have plummeted. A bird cremation machine. The criticism is not limited to the technical aspects. The Ivanpah plant has been questioned for years for its environmental impact, especially on desert wildlife. Environmental groups denounce the irreparable damage to the habitat of species such as the desert tortoise. But also the death of birds that are incinerated by the intense rays concentrated by the mirrors. A second Crescent Dunes. The case of Crescent Dunes, also occurring in Nevada, reinforces this image of failure of solar thermal energy. This project, which was intended to be one of the milestones in innovation and energy storage using molten salts, ended up becoming a multimillion-dollar waste. Developed by the Spanish group ACSpromised continuous production of electricity, even during hours without light, thanks to thermal storage in salts. In practice, Crescent Dunes never managed to deliver the promised amount of energy and ended up going bankrupt due to engineering and management problems. In the shadow of photovoltaics. In short, the rapid fall in prices of photovoltaic technology and its lower impact on wildlife have made concentrated solar thermal obsolete. While solar panels have been gaining efficiency and reducing their installation and maintenance costs, solar thermal plants have lagged behind in terms of competitiveness, which has led investors and electricity companies to reconsider their bets on this type of projects.

While the news says that it is dying between solar panels and expropriations, the data says the opposite

by

Solar panels that destroy olive trees, massive expropriations in Jaén, warnings that Spain will have to import oil… If we pay attention to the last few months of news about the world of olives, the conclusions are clear: these are bad times for the olive grove. And yet, the data does not confirm this. In fact, as they point out from Datadistathe surface area of ​​this crop has not stopped growing in the last 10 years. The olive grove does not stop growing. With the only exception of the small decline in 2022 (0.08% already recovered in 2023), the hectares of olive groves have grown every year. However, that does not mean that there is no problem. Almost the opposite. The olive grove grows, but it does so in a profoundly unequal way: irrigated land gains ground over dry land, the super-intensive olive tree in a hedge extends over land previously dedicated to cereal or cotton, and investment funds are concentrated in areas with more water. In this sense, the story is not about the disappearance of the olive tree. It’s about changing so much and so fast that it will soon be unrecognizable. What the data says. Apparently, the data is clear. According to provisional data from the Survey on Crop Areas and Yields (ESYRCE) 2025 From the Ministry of Agriculture, Fisheries and Food (MAPA), the olive grove area in Spain reached 2,873,396 hectares, 1.63% more than in 2024 and 5% more than in 2015. It’s just that if we look closely, that data tells a curious (and sometimes counterintuitive) story. For example: the olive tree is already the largest irrigated area in the country. And why does this change occur? Above all, because the irrigated olive grove is safer than the dry one. If it were possible, the entire Spanish olive grove would switch to irrigation regime overnight. Therefore, the interesting thing is to stop and think about why the accelerated change is occurring now. According to a February 2026 report from Datadistathe explanation has a first and last name: investment funds. In the last decade, these funds have gone from 45 to 1000, investment in “Iberian agribusiness” has tripled and this is converting many hectares into super-intensive olive trees (and abandoning the traditional one). And the situation feeds on itself. The growth of the super-intensive irrigated olive grove cushions the volatility of supply and, therefore, contains price spikes. That is, the sector becomes more attractive to investors. This is precisely what ensures the future of olive oil. Even if it is at the cost of changing it completely.

China’s largest solar park is doing much more than generating energy: it’s greening a desert

by

more than a year ago we had in Xataka how a huge solar park in the Chinese province of Qinghai, in the heart of the Tibetan plateau, served as an ecological experiment: under the panels, the shade retained moisture and made vegetation sprout in the middle of the desert. Now, that same place – the Talatan Solar Park – has become something much bigger. It is the largest clean energy facility on the planet, a “blue sea” of silicon that already covers more than 600 square kilometers at three thousand meters above sea level. Where before there was nothing, China is lifting an energy ecosystem without comparison in the rest of the world. The scale has multiplied. Where last year there was talk of a 1 gigawatt solar park, today a complex extends that reaches 15,600 and 16,900 megawatts and continues to expand. Its area – between 420 and 610 square kilometers – is seven times that of Manhattan. Furthermore, it is not alone since 4,700 megawatts of wind energy and 7,380 megawatts of hydroelectric dams are deployed around it, completing an unprecedented hybrid system. The result: enough renewable energy to supply almost all of the plateau’s needs, including the data centers that power China’s artificial intelligence. According to CleanTechnicaevery three weeks China installs as many solar panels as the entire capacity of the Three Gorges Dam, the largest hydroelectric project in its history. A global clean energy laboratory. The Tibetan plateau, with its pure, cold air, has become the most ambitious energy laboratory in the world. There, China is experimenting with an electricity production model based exclusively on renewables. Electricity generated in Qinghai—40% cheaper than coal, according to the NYT— powers high-speed trains, factories, electric cars and data centers. In fact, the region is home to new computing centers dedicated to artificial intelligence, which consume less energy thanks to the altitude and low temperatures. “Hot air from servers is used to heat other buildings, replacing coal-fired boilers,” explained Zhang Jingang, vice provincial governor. In the words of Professor Ningrong Liu, in his column for the South China Morning Post: “China is not only leading the transition to green energy; it is building the 21st century energy scaffolding that sustains its industrial leadership in electric vehicles, batteries and solar technology.” Three sources that beat in unison. The magnitude of the project is only possible thanks to centralized planning that combines three main sources: solar, wind and hydroelectric energy. During the day, Talatan panels capture more intense solar radiation than at sea level; At night, thousands of wind turbines collect the cold breezes that sweep across the plains. When both systems fluctuate, hydroelectric dams balance the grid. Also, from the New York Times They described a system reversible pumping: excess solar energy during the day is used to raise water to reservoirs located in nearby mountains, which release that water at night to generate electricity. And under the panels, life returns. The shade of the plates reduces evaporation and soil erosion. According to China Dailythis year the vegetation has recovered up to 80% and 173 villages have benefited from the associated livestock farming. A local shepherd, Zhao Guofu, said: “My flock has grown to 800 sheep and my income has doubled since I grazed between the panels.” The perfect geography for the sun. No other country has taken solar generation to similar altitudes. The altitude plays in favor of physics, at 3,000 meters the air contains fewer particles that block light and the low temperatures reduce the thermal loss of the panels. This efficiency is multiplied in Qinghai, one of the few areas of the Tibetan plateau with large plains, where it is possible to build without the limits of the mountainous relief. The Talatan Desert, once an arid and worthless land, has become an energetic jewel. local authorities offer symbolic leases and have developed roads and high-voltage lines connecting the plateau with the industrial centers to the east. That energy travels more than 1,600 kilometers to factories and cities. According to CleanTechnicaChina already operates 41 ultra-high voltage transmission lines, some longer than 2,000 miles and up to 1.1 million volts. The global scale: no one comes close. Other countries have tried to generate clean energy at altitude, but with modest results. Switzerland, for example, inaugurated a small solar park in the Alps, at 1,800 meters, with barely 0.5 MW. For its part, in the Chilean Atacama Desert, a 480 MW project operates at 1,200 meters. By way of comparison, the Talatan complex multiplies the capacity of the Bhadla Solar Park in India, and for more than seven that of the Al Dhafra Solar Park in the United Arab Emirates, which until recently held records. The superpower of clean energy. China produces and consumes more renewable energy than any other country on the planet. In 2024, was responsible of 61% of new solar installations and 70% of global wind power. That same year, it achieved the capacity targets it had set for 2030. In the first six months of 2025added 212 GW solar and 51 GW wind, and the country’s carbon emissions fell for the first time. In this context, Talatan Park is both a symbol and an infrastructure. China is exporting its renewable technology around the world, from Asia to Africa, following the logic of Belt and Road Initiative. For the academic Ningrong Liu: “China wants to stop being the world’s factory to become the engine of the world’s factory.” It is not just about manufacturing panels, but about selling the complete model: engineering, financing and know-how to build green networks in other countries. The less visible side of the miracle. It’s not all clean energy and pastoral harmony. In its report, The New York Times recalled that access to Tibet remains strictly controlled by the Communist Party, and that Western media were only allowed to visit Qinghai on a government-organized tour. There are also human and environmental costs. CleanTechnica documents how the giant power lines that transport energy … Read more

A family wanted to live with only solar panels, well water and a garden. Until Italy took away her children

by

High in a forest in Abruzzo, Italy, a stone house fell completely silent in November last year. Until then, that place was the self-sufficient refuge of Nathan Trevallion, Catherine Birmingham and their three children. However, on November 20, 2025, a judge decided to remove them of family custody for living disconnected from the grid, without schooling and in an environment that he considered unhealthy. The resolution started a fire political and social in Italy. What for the family was a self-sufficient life project—solar panels, well water, compostable toilet, garden—became a court case with enormous international repercussions. The story, however, goes beyond an Italian court order. It is the symptom of something bigger: a growing movement in Europe—and also in Spain—of families and communities seeking to get out of the urban grind, disconnect from the electrical grid and live self-sufficiently. How far does the freedom to choose that lifestyle go? And where does the State’s intervention begin, especially when minors are involved? The case that divided Italy. The family, of Australian and British origin, had been living in a forest in Palmoli since 2021. The house was precarious but, according to themenough: electricity with solar panels, well water and an outdoor composting area as a toilet. In autumn 2024, all were hospitalized due to accidental mushroom poisoning. That episode was the one that activated the alarms of social services. As collected Corriere della Seraa technical report described the home as “ruin” and “without adequate conditions for minors.” That’s when social services intervened. The lack of schooling of the minors, the absence of pediatric follow-up and the almost total isolation in which the family lived set off all the alarms. Following these reports, a court in L’Aquila ordered in November of 2025 the withdrawal of parental authority and the transfer of the children to a center, where the mother could stay with them temporarily. The decision has caused a real political earthquakewhere political leaders and several judicial associations denounced pressure from the Government. At the same time, more than 150,000 people signed online petitions demanding that minors return to their parents. The family breakup and tensions in Vasto. The litigation is still in full swing. The development of the case during the first months of 2026 has been marked by institutional complexity, friction and the desperate search for reunification. The deepest wound of this process is, without a doubt, separation. According to Il Messaggerothe situation reached a critical point on March 6, when Catherine, the mother of the minors, was removed from the Vasto family home. In her only in-person visit after the expulsion, social services reports indicated that the woman showed “hostile” attitudes and incited other residents to rebel against the educators. This episode led to the drastic decision to cancel subsequent meetings, limiting maternal contact to video calls, in an attempt to preserve the children’s serenity. However, distance is taking its toll. A forceful technical report presented on April 3, 2026 before the L’Aquila Court, signed by the psychiatrist Tonino Cantelmi and the psychologist Martina Aiello, set off alarm bells. The experts They noticed that children show obvious “signs of psychological distress” and deep trauma resulting from the separation. The document is clear: there is no evidence of abuse or mistreatment by the mother. For this reason, specialists have asked the court for the “urgent and unavoidable” reconstitution of the family, warning that prolonging this fracture will only aggravate the damage to the mental health of the children. An institutional clash in the middle of the crossfire. The family drama has transcended the walls of the reception center to become a political and institutional powder keg. The management of the case provoked an open and public confrontation, collected by RaiNews. On the one hand, the Ombudsman for Children of Abruzzo, Marina Terragni, visited the minors in March and publicly reported having found some children with “notable psychomotor agitation” and obvious trauma due to the repeated changes. The response from social services was immediate. They flatly accused Terragni of exposing the professionals to a “public pillory” based on statements that, according to them, did not correspond to reality, ensuring that the climate in the family home had returned to being “serene.” Polarization and media pressure have escalated to worrying levels: The tension even manifested itself with screams inside the court itself, and the judge of the Juvenile Court, Cecilia Angrisano, had to receive a police escort after being the target of continuous threats on social networks. The countdown. While the courts decide, the family tries to put the pieces back together and comply with the State’s demands. Nathan, assuming a conciliatory role, has moved to regularize his situation. As detailed Il Messaggerothe father delivered to the City Council of Palmoli a personalized study plan, supported by the Libera Schola Foundation of Milan and inspired by the Waldorf-Steiner method. In addition, the family has begun to comply with the vaccination schedule and the children have been receiving in-person classes with a tutor since January, as pointed out by Corriere della Sera. The most tangible progress has come from the municipality itself. In a gesture of support, the Palmoli City Council has given the family, free of charge and for an initial period of two years, a newly renovated 70 square meter house. As detailed Il Giornale, The house, financed with European PNRR funds, has solar panels, heating and all health guarantees, thus solving the judge’s main claim. At the moment the house remains empty until the family is complete, as detailed by Nathan. Everyone’s eyes are now on the Court of Appeal, which has a key hearing set for April 21, 2026. Off-grid: from bucolic dream to global phenomenon. To understand the background of this trend, just open Instagram. As the magazine explains Ethicsit is enough for the algorithm to detect a certain interest in self-sufficiency to fill the feed of videos of families drying their own food, women showing their renovated campers or couples who live half a year off … Read more
