installing a socket is now twice as expensive as before

by

For years, adding a plug to your home was one of those small jobs that were barely thought twice about: a call to the electrician, a morning of work, and an affordable cost. However, that perception has changed. A video by the electrician and popularizer Ricardo Abellán —known as @dombydomotica— has focused on a reality that many homeowners are beginning to notice in their budgets: installing a plug has gone from around 30 euros to around 50. On the rise. The increase in the cost of new plug points has become widespread in recent years, driven by structural changes in the electricity sector. To understand what is behind this increase, we must look beyond the final budget and pay attention to what is happening within the sector itself. This is how he explains it to Xataka Luis Catalan, business development director Home & Distribution Schneider Electric Iberiawho points to a combination of economic, technical and regulatory factors that have completely transformed this type of facilities. A rise that is not coincidental. The increase in the price of installing a plug is not the result of an improvised rate increase. Behind it there is a sum of factors that have been putting pressure on the sector for years. As Luis Catalán explains, the increase in the cost of raw materials has had a direct impact on electrical materials, to which is added the higher cost of energy and an increasingly specialized workforce. Added to all this are less visible expenses, such as transportation, insurance or the tax burden, which have been growing steadily. The result is a context in which even the smallest interventions are affected by a much more demanding cost structure than a decade ago. More regulations, more technical complexity. However, the economic context does not explain everything. The most relevant change is in the evolution of the regulations and in the level of technical demand applied to any electrical installation. Both the Electrotechnical Regulation for Low Voltage (REBT) like him Technical Building Code (CTE) They have tightened the requirements, forcing the use of certified materials and a more complex execution of the facilities. A transformation aimed at improving security and energy efficiency in the home. What once seemed like a quick job now requires much more attention. Placing a plug involves checking that the ground connection is in good condition, checking the differentials and ensuring that the installation supports the expected consumption. Furthermore, materials are no longer interchangeable: they must be certified and comply with regulations. As Catalán points out, ignoring these controls can translate into greater electricity consumption and, in the worst case, security problems inside the home. Safety, at the center of the installation. This regulatory change has also raised the level of responsibility of the professional. At each new connection point, the electrician must guarantee that the entire installation is safe and complies with current regulations. An approach that matches what Ricardo Abellán explained in his informative videos: Before it was enough for the plug to work; Now it is essential to check that there is no risk of overload and that the electrical system responds correctly. If something fails, the responsibility falls directly on the installer, which adds an additional layer of demand, time and checks to each intervention. The risk of doing it on your own. Given the increase in prices, some users choose to install plugs without professional help or permanently resort to power strips. The sector warns that these decisions may entail significant risks. According to Catalán, an installation carried out without a certified professional can lead to electrical failures, accidents or fires caused by electrical arcs, loose connections or overloads. Furthermore, not complying with current regulations can generate legal problems and security for the owner. In this sense, the power strips are only recommended for occasional use. When consumption is continuous or of greater power, the safest option is still to install a specific plug point. More devices, more plugs. The reality within homes has also changed evidently. Today we live with many more electronic devices than a few years ago, which has multiplied the need for connection points and has forced us to rethink how electrical installations are designed. From home automation systems until electric vehicle chargerspassing through smart air conditioning either small connected deviceseach element requires specific planning. At the same time, the plug itself is no longer a basic element. There are models that incorporate USB ports or that allow control and monitor electrical consumptionan evolution that improves energy efficiency, but also adds complexity to the installation. A future with more demand and fewer professionals. Added to this is a structural problem in the sector: the shortage of qualified electricians. According to Catalán, there is not only a lack of professionals, but also profiles with digital skills and the ability to adapt to technological change, a lack that influences both the prices and the execution times of the work. The plug as a reflection of the change in the home. What was once an almost invisible work has become an indicator of how our homes have changed. The plug, a symbol of something basic, today reflects the rising cost of materials, the evolution of regulations, the professionalization of the sector and a different way of consuming energy. In this new scenario, installing a plug implies safety, regulations, technology and responsibility. And that explains why what was once barely thought twice about has today become a small, but significant, household expense.

why OpenAI is installing Boeing 747 engines in its data farms

by

Just three years ago, Blake Scholl, CEO of aviation company Boom Supersonic, had a linear business plan: He would first build the supersonic plane of the future and, much later, retrofit its engines to generate power. However, a phone call changed the order of factors and revealed the desperation of the technology industry. On the other end of the line was Sam Altman. The OpenAI CEO’s message was a direct plea: “Please, please, please get us something.” Altman wasn’t looking for plane tickets; I was looking for electrical power. This anecdote, reported to the Financial Timessummarizes the state of emergency in the sector: artificial intelligence is advancing at breakneck speed, but it has hit the wall of physical infrastructure. While the AI evolves in monthspermits to connect to the electrical grid can take up to ten years in some regions. Faced with this paralysis, the industry has opted for “Plan B” which consists of bypassing the grid and manufacturing its own energy on site. The tall price of urgency. This strategic shift has profound consequences. The first is economic, the “delay” is expensive. According to BNP Paribas analystspower from a gas plant built for Meta in Ohio costs about $175 per megawatt hour, nearly double the average cost for an industrial customer. The second is environmental. Mark Dyson, from Rocky Mountain Institutewarns that the emissions of these plants are much worse than those of the general network, which combines efficient gas with renewables. Despite this, the urgency is such that the authorities are giving in. In Virginia, the world’s data center heartland, it is considering relaxing emissions rules to allow generators to run more frequently. Even polluting plants that were in retirement, like the Fisk plant in Chicagohave canceled their closure to feed the demand for AI. From the sky to the data center. The most surprising solution comes from aeronautical engineering through aeroderivative turbines. The ProEnergy Company are buying motor cores CF6-80C2 of the iconic Boeing 747 to rebuild them as ground power units. A single one of these turbines generates 48 megawatts, enough for a city of 40,000 homes. It is not an isolated case. GE Vernova already supplies this technology for the gigantic Stargate (OpenAI/Microsoft) data center in Texas. Blake Scholl himself confirmed that it will sell Crusoe turbines “practically identical” to those of his supersonic planes to finance his aeronautical project. The return of diesel. Beyond aviation turbines, the sector is rescuing the most reviled fuel: diesel. The manufacturer Cummins has already sold 39 gigawatts of energy to data centers, doubling their capacity this year. What was once emergency equipment for power outages is now in demand as a primary energy source. The situation has escalated to the US Government. Secretary of Energy, Chris Wright, suggested on Fox News an almost war economy measure: requisition the backup generators from data centers or large stores like Walmart to turn them over to the network when the general system falters. The ignored alternative: Is smoke necessary? Not everyone agrees that the return to the fossil is inevitable. A study by researchers at Stripe, Paces and Scale Microgrids maintains that the future is in “off-grid” solar microgrids. According to their calculations, a system with 44% solar energy is already as cheap as gas, and one with 90% renewables would surpass nuclear projects in profitability. The advantage is speed since these solar farms can be built in less than two years in desert areas from Texas or Arizona. Giants like Google have taken note, buying the electric company Intersect Power for 4.75 billion dollars to protect its clean supply and not depend on the network. However, the majority industry prefers diesel and known gas due to a matter of technical inertia, due to the prosaic fear that the cloud will go out if the sun does not shine. AI goes physical. The industry finds itself in a technical paradox. To power the most advanced software on the planet, big technology companies are resurrecting combustion engines and burning fossil fuels on a massive scale. Although these “bridge turbines” allow AI to continue growing today, experts cited by the Financial Times They warn that this fever could cool as the tech giants reduce their capital spending. For now, the cloud has had to come down to earth. The future of artificial intelligence, ironically, depends not only on brilliant code, but on who controls the underground and who manages to turn on enough “plugs” so that the greatest technological revolution of our era is not left in the dark.

How to watch YouTube without ads and in the background without paying for YouTube Premium or installing fake apps

by

Let’s tell you How can you watch YouTube without ads on your mobile or computerand even with the option to watch the videos in the background. These are features available to paying users on YouTube Premiumbut we are going to tell you how to do it without paying. We are going to do this using third-party apps, but without resorting to fake applications or those that are a modified YouTube and that expose you to privacy dangers. Nor are they the apps to listen to music on YouTube as if it were Spotify. Some browsers will help you with this There are three key functions that YouTube Premium offers you, which is to watch videos without ads, listen to their audio in the background, or even use the mode Qicture-in-Picture with which to watch videos in a floating window while you are using another application. This is something you can do with other paid apps. The trick is use some specific browsers instead of Chrome or Safari. They are perfectly normal, safe and legal browsers, so you don’t need to go around installing modified versions of YouTube that are going to become a problem for your privacy. There are three very popular browsers that you can use for this, which are Brave, Firefox and Vivaldithe latter with the extra of being a European alternative. You can find these browsers both in the official application store of your mobile phone, and you can also download them to your computer. Brave is the best option for mobileas it allows you to use PiP mode to have the video play in an overlay window while you do other things. Vivaldi, on the other hand, only removes the ads, which is no small feat either. Just remember, you have to use YouTube from the browsernot from the app, entering m.youtube.com. For background playback With Brave, you’ll need to turn it on in the app’s settings. For this you will have to enter the configuration, and in the section Multimedia. Here activate background playback. For the computer any of the three options are goodsince they will allow you to watch YouTube without ads. This is due to the internal blockers they have.

Barcelona is tired of cars not respecting the bus lane. So it’s installing AI cameras on its buses

by

2,500 violations in one month. That is, Barcelona City Council could have fined more than 80 drivers every day. It has not done so because, at the moment, the project is in the testing phase, but it has served the City Council to confirm its suspicions: the invasion of the city’s bus lanes is a constant and a real problem. To confirm this, Barcelona City Council has launched a pilot test equipping four buses with cameras enhanced with artificial intelligence. They are units of lines H12, which crosses the city on Gran Via de les Corts Catalanes, and D20, which in this case covers the entire route of Avinguda del Paral-lel and a nearby section around the port. The project was already presented last February but it wasn’t until summer when we knew all the results. Four buses and 2,500 violations The data published suggests that something is not working in the Catalan city. They collect in Hybrids and Electrics that just four units collected more than 2,500 violations in just one month. These infractions have not been sanctioned because, as we said, it was a pilot project that will serve to define new strategies and look for solutions. The truth is that it is obvious that the Barcelona transport company has to deal daily with all types of vehicles that illegally occupy a space that should serve to prioritize the passage of public transport. To record these infractions, the cameras recorded the movement and position of the vehicles as the bus moved forward. They specified in the presentation of the project that cameras have not been used in the study to identify people or license plates. The software, they say, only counted if there was an object blocking the road and is capable of discerning illegal occupations, such as a parking lot, from those permitted (taxis, right turns…). With the data they want to propose solutions among which, of course, the possibility of turning buses into real moving radars has not been mentioned. Although buses have highlighted the problem, the truth is that Barcelona already has the so-called “multacar”cars with cameras that record violations of the bus lane and that, these do, issue penalties with the violations found in their path. And the city council also has similar vehicles that They control regulated parking areasinstantly checking if a car has exceeded the allowed time and, in that case, fining it. The big difference is that installing this system on the buses themselves would allow the fleet to become an exercise in constant surveillance throughout the service. And taking into account the data recorded, the volume of sanctions would be expected to be very high in that case. Photo | TMB In Xataka | FlixBus wants to operate international bus lines in Spain.

India needs more crops and solar energy than any other country. So you are installing solar panels in height

by

When a solar energy company offered Harpal Dagar a fixed pay for 25 years in exchange for installing solar panels on their cultivation fields, he thought it could be a scam. Today he says that his income has tripled and sleeps quieter. “Too good to be true.” That was what this Indian farmer thought when the company Sun Master proposed to install elevated solar panels on its land on the outskirts of Delhi. I could continue working the land and, in return, would receive an annual payment for 25 years. According to a report of BBC NewsDagar had lost entire crops because of the Monzones, so he accepted the installation of the panels to have fixed income. “Today I think it was the best decision I have made,” he told the British environment. Harvest food and energy at the same time. The systems that combine agriculture with solar energy generation in the same land have a name: agrovoltaic. And in the most populous country in the world they are emerging as the most promising solution to produce clean energy without sacrificing the land necessary to feed the population. The agrovoltaic part of a simple idea: take advantage of the vertical space. Instead of choosing between a crop field or a solar park, They both haveonly that photovoltaic panels are mounted on high structures, at a height of at least three and a half meters so that tractors and other agricultural machinery can pass below. India cannot do without cultivation soil. In India more than 55% of the population It depends on agriculture. As the country approaches the 1.7 billion people in 2050, it will have to produce about 350 million tons of grain At the same time, India has pledged to meet ambitious climatic objectives that will require dedicating solar and wind energy between 55,000 and 77,000 square kilometers of land. According to a report from Mongabay Indiaagrovoltaic would resolve this paradox of “food security vs. access to energy”. Not everything that shines is gold. Sun Master pays Harpal Dagar about $ 500 per hectare per year, plus a monthly salary of 170 dollars for the maintenance of the panels. Dagar cultiva turmeric, which benefits from the microclimate created by the solar panels. Its shadow protects the cultivation of extreme heat and decreases water evaporation, reducing irrigation needs. It is not always beneficial. Depending on their disposition, solar panels reduce between 15 and 30% the light that reaches plants. This makes basic cultures that need a lot of sun, such as wheat, rice or soybeans, are not viable. Anand Jain, another farmer who has experienced with the system, says he succeeded with strawberries and tomatoes, but “the cauliflower did not work so well.” The green leafy vegetablesginger and some flowers have also benefited. The slow takeoff from agrovoltaic. The adoption of agrovoltaic in India is being slow, especially compared to China, which has 12 times more projects in operation. Incompatibility with some crops is one of the problems, but there is an even greater financial problem: raising panels more than three meters from the ground has a price. The installation of an agrovoltaic system is between 20 and 30% more expensive than that of a conventional solar park. Small farmers cannot afford these systems, so they depend on companies with capital that want to rent their land with a 25 -year contract. Technology will solve some challenges. For companies to be willing to assume that risk, more efficient and profitable systems are already being developed. “Farm-Forward” solar panels with More space between panel ranks to maximize the entry of light and further facilitate the step of machinery. And new software to simulate how much light and heat receives each sheet, how it affects photosynthesis and, ultimately, what performance of the harvest. The potential is simply gigantic. A GIZ technical report He estimates that agrovoltaic in India can point to a capacity of between 3,156 and 13,803 gigawatts. To put it in perspective, the total installed capacity of photovoltaic energy worldwide is 2 GW. In Xataka | One of the most arid areas in China is reverde.

In Italy, farmers are so fed up with tourists who are installing lathes in the mountains. Literally

by

There are many places where one would expect to find a lathe. In museums, airports, subway stations, libraries, gyms, bathrooms, stadiums … the list is long and wide. But where nobody would probably expect to see an access tourniquet is in The dolomitesthe steep mountains of the Italian Eastern Alps. After all, what does a metallic closure paint in the field? If that question is asked the farmers of Seda The answer is to remove tourists. That is why they have installed a lathe on a busy route in the area An unexpected landscape. Alps have accustomed us to postal landscapes, but not to what can be seen for weeks on one of its most popular paths, the SECEDA ODLE PANORAMIC ROUTEa mountain of the dolomitas located in Val Gardena. In addition to green slopes, steep summits and film sunset, from early July In the area there is a new element that alters the landscape: a metallic lathe, with its bars, its coin slot and A poster in which you can read “Input for the famous Ruta de las Rocas € 5”. And who put it there? A group of local farmers tired of seeing the continuous transfer of tourists in search of photos for Instagram or the best Selfie. The Telegraph Precise that the initiative started from four land owners that crosses the path. It is not just that the area receives thousands of visitors in high season (recently There was talk of 8,000 in a single day), which already exerts remarkable pressure in the environment, is that this influx, They denounce The owners of the plots, arrives accompanied by “damage” to their lands and garbage. “The authorities must understand that while the cable car operators receive large amounts of money due complaint Georg Rabanser, owner of one of the land that crosses the path. Hence the decision to install a lathe with a toll of five euros (children and locals are exempt) and a person who is responsible for controlling access and demanding the payment of the rate. A QUITA AND PUT TORN. The initiative of Italian farmers could stay there if it were not because the lathe unleashed a considerable controversy in the country. A few days after jumping the news, the device I was already canceledwith which the hikers rose again without problem (or tolls) to the Mirador de Odle. Was that the end of the story? No. Yesterday the newspaper Il post He informed that the lathe is again operation with its controversial rate. OBJECTIVE: launch a SOS. Its promoters decided to recover it to achieve what, They assureThey have always sought: to agit consciences between public administrations to seek solutions to the intense flow of tourists, “the abandoned paths and the meadows full of garbage.” “Ours has been a call for help. We expected a call from the provinces authorities. But nothing. We only read communicated in the press, rumors, nothing concrete.” “We have not even received warning letters, so we move on. The province must understand that, while the facilities (tourist) earn a lot concludes Rabanser. The debate, served. The debate of course is served. The owners of the plots through which the path passes allege that their lands suffer the avalanche of tourists, but the situation is much more complex. Italian law allows free access to environments such as Dolomitas, although in the country there are certain placeslike the popular Via dell´amorein Cinque Terre, which charge access rate. In the background there is an even broader debate and with implications that go beyond Seeda: if farmers are allowed to install lathes, the same will be allowed to the owners of other plots crossed by tourist paths? A lathe field? “I do not want the southern tyrol to become a territory of tourniquetes,” insists Carlo Alberto Zanella, from the Italian Alpine Club. “It is unthinkable that every owner of land crossed by routes begin to collect tolls for access.” Torns are not the only way to prevent tourists from damaging the environment. Moreover, the authorities have already hired more forestry to prevent visitors from leaving the trails or using drones. Images | Robert J.

Germany is installing giant concrete spheres under the sea. You have a good reason: store renewable energy

by

While France and Germany reinforce their energy alliances with a renewed bet For nuclear energy, within the German country they are developing a completely different system. The focus is on marine depths, with the aim of redefining the way in which renewable energy is stored. Under the sea. A group of researchers the Fraunhofer Institute of Germany They have created the Stensea project (Stored Energy AT Sea acronym). Since 2011, the equipment has worked in a solution to reduce land use, reaching the conclusion of sinking huge concrete spheres into the seabed to store energy. The operation. These spheres sink at 600 and 800 meters deep, where water pressure is so high that it can rotate turbines with great efficiency. Each one measures about 9 meters in diameter and weighs about 400 tons. The idea is that they work as giant batteries: by letting the sea water in, it moves a turbine connected to a generator. To recharge it, water pumps out, using network energy to overcome environmental pressure. A design of what a Stesea plant would be A real test. The system has already been successful at Lake Constanza, and now the next step is marked in the calendar by 2026. It is expected to install a prototype real and 3D printed on the coast of Long Beach, in California. This model can generate about 0.5 megawatts and store up to 0.4 megawatts-Hora, which would be enough to cover the consumption of a middle home in the United States for about two weeks. The future idea is ambitious: building much larger spheres, up to 30 meters in diameter, capable of storing much larger amounts of energy. The objective is to climb the system with spheres up to 30 meters in diameter, which would allow a much larger storage capacity. According to They have detailed Newatlas researchers, the estimated storage cost around the 5 cents per kilowatt-hora, a very competitive figure compared to other current solutions. Renewables in Germany. Although it seems contradictory for its climate, the country has been strongly betting on solar energy, especially In self -consumption facilities. However, it faces an important challenge: intermittent production, or Dunkelflaute. For this reason, projects such as Stesea can act as a shock absorber of the electrical system, because it stores excess renewable energy and releases it when it is most needed. So hydroelectric plants? Unlike traditional pumping storage –which requires mountains and large fresh water reserves-, this system does not need limited elevations or water resources. Its modular design allows it to install it on coasts around the world. In addition, this system has raised An economic advantage since it allows energy arbitration, buying electricity when it is cheap and selling it in moments of high demand. Forecasts The researchers They believe that this technology He has barely shown the tip of the iceberg. They estimate that, if it was deployed on a large scale, it could reach a global storage capacity of about 817,000 gigawatts-Hora. Translated to something more tangible, it would be enough to supply about 75 million homes in Europe for a whole year. However, although the project is presented as a solution to avoid intensive soil use, it does not stop moving that occupation to the seabed. Until now, the approach has been mainly technical, but it would be expected that in future phases rigorous environmental evaluations will be included that analyze its impact on oceanic ecosystems.

France is installing turbines under the sea to exploit the renewable energy source that never ceases: the tides

by

In the heart of the sea, where the powerful tidal currents move to the rhythm of lunar gravity, an energy revolution is being created that promises to transform the future of Europe. France has a continuous energy with a large -scale installation. The project. French company Normandie Hydroliennes has created The NH1 initiative to generate energy from sea currents. The installation will consist of four seniomotor submarine wind turbines that will be located in the Raz Blanchard, a sea step known for its currents. The great support. EU 2023 Innovation Fund He has subsidized to the project with 31.3 million euros. In this way, Europe expects to integrate tidal energy into the energy mix in France and Europe, adding a constant and predictable source to avoid Intermittent energy problems. The largest in Europe. Thus it will be thanks to the AR3000 turbines, which are considered The most powerful in the world in the mareomotor energy sector. Each turbine will have a 3MW power and a 24 -meter rotor diameter and, its advanced control system will constantly adjust the speed and angle of the blades to optimize the production of electricity. It should be added that the marine structure of these turbines allows them to be installed in just 20 minutes. Stable energy. An interesting small fact is that this type of renewable energy offers a stable and continuous supply, thanks to Natural forces as the lunar gravity that generates the tides and moves the oceans continuously. Energy sending. The energy generated by the turbines will be transported to the ground through a single export cable, which facilitates the connection of multiple turbines to transmit the electricity generated efficiently. This type of very demanded cables in Europe It has made effective The network connection between England and Denmark, among other projects. However, too It has been target of objectives In geopolitical conflicts. The occasional setback. Like any type of large -scale system, problems may appear. The company has indicated that the design of the project minimizes the environmental impact and reduces costs, but problems may arise due to the extreme marine conditions of the sea pass. As for the marine impact, problems may arise of local fauna and flora. Forecasts. From the French company have indicated which will provide 34 GWh per year to the France electricity network from 2028. In addition, they have estimated that this energy source has a potential of up to 100GW by 2050, supplying the electrical needs of 94 million homes throughout the continent.
