A new sand battery has become operational in Finland, designed to store thermal energy from wind and solar sources. This innovative technology aims to help residents eliminate oil from their district heating network, potentially reducing emissions by nearly 70 percent. The battery stands 13 meters high and 15 meters wide, showcasing that sand can be an affordable and effective means of energy storage.

The process involves filling a tall tower with low-grade sand, which is heated using excess electricity generated from renewable sources. This heating occurs through resistive heating, where friction from an electrical current creates heat. The stored heat can reach temperatures of around 500°C (932°F) and can be maintained for several days or even months. When needed, the hot air is released to warm water in the district heating system.

According to Polar Night Energy, the company behind this project, the battery's capacity can meet almost a month's heat demand during summer and about a week's demand in winter. The company has plans to expand its technology globally and is currently discussing partnerships both within Finland and internationally.

The input text conveys a sense of excitement and optimism, as it introduces a new innovative technology that has the potential to significantly reduce emissions and help residents eliminate oil from their district heating network. The phrase "A new sand battery has become operational in Finland" sets a positive tone, implying that something groundbreaking is happening. The description of the battery's size and design, standing 13 meters high and 15 meters wide, showcases its impressive scale, further emphasizing the innovation.

The use of words like "innovative," "affordable," and "effective" creates a sense of pride in the technology's capabilities. The company behind this project, Polar Night Energy, is portrayed as forward-thinking and committed to reducing emissions. This portrayal aims to build trust with the reader, making them more likely to believe in the potential benefits of this technology.

The text also conveys a sense of hope for a cleaner future. Phrases like "potentially reducing emissions by nearly 70 percent" create a sense of possibility and promise. The idea that this technology can meet almost a month's heat demand during summer and about a week's demand in winter reinforces this hope, suggesting that it could be a reliable solution for energy storage.

The writer uses special writing tools to increase emotional impact. For example, they compare sand batteries to other energy storage methods by highlighting their affordability and effectiveness. This comparison aims to make sand batteries sound more attractive than other options might seem.

However, there is no apparent attempt to create sympathy or worry in the reader. Instead, the focus is on inspiring action by showcasing the potential benefits of this technology. The text does not try to make something sound more extreme than it is; rather, it presents facts about the sand battery's capabilities in an objective manner.

This emotional structure can be used to shape opinions or limit clear thinking if readers are not aware of how emotions are being manipulated. By presenting information in an optimistic light without providing balanced perspectives or acknowledging potential drawbacks, readers may form overly positive opinions about sand batteries without considering all relevant factors.

To stay in control of how they understand what they read, readers should be aware of how emotions are used throughout an article or text. Recognizing when information is presented with enthusiasm or pride can help readers separate facts from feelings and make more informed decisions based on evidence rather than emotional appeals alone

The text presents a clear example of virtue signaling, where the company behind the project, Polar Night Energy, highlights the innovative and environmentally friendly nature of their technology. The phrase "help residents eliminate oil from their district heating network" (emphasis added) reveals a bias towards promoting renewable energy sources as inherently virtuous. This framing assumes that oil is inherently bad and that eliminating it is a desirable goal, without providing any evidence or context to support this claim.

The text also exhibits linguistic bias through its use of emotionally charged language. The description of the sand battery as "innovative" and "affordable" creates a positive emotional association with the technology, while phrases like "potentially reducing emissions by nearly 70 percent" create a sense of urgency and importance around the issue of climate change. This language manipulation aims to sway readers into supporting the project without critically evaluating its merits.

The text presents a clear case of selection bias in its presentation of facts and viewpoints. By highlighting only the benefits of the sand battery technology, such as its ability to store thermal energy from wind and solar sources, while omitting potential drawbacks or limitations, the author creates an overly optimistic narrative about this new technology. For example, when discussing how long the stored heat can be maintained, it states that it can be kept for "several days or even months," without providing any context about what this means in practice or how it compares to other forms of energy storage.

The text also exhibits confirmation bias in its uncritical acceptance of data-driven claims made by Polar Night Energy. When stating that "the battery's capacity can meet almost a month's heat demand during summer and about a week's demand in winter," there is no mention of how these claims were arrived at or what methodology was used to determine them. This lack of critical evaluation allows unverified data points to shape public opinion about this new technology.

Furthermore, structural bias is evident in the way authority systems are presented without challenge or critique. The company behind this project is portrayed as experts on renewable energy solutions without any examination or questioning about their motivations or potential conflicts-of-interests involved in promoting their own product line-up under guise environmentalism

In addition to these biases mentioned earlier we have framing narrative bias when story structure metaphor sequence information especially when shaping reader conclusions are used here for instance when describing heated sand tower being filled with low-grade sand using excess electricity generated from renewable sources then releasing hot air warming water district heating system creating sense urgency importance around issue climate change
