Geometrisk Energi: What to Know About This?

    There’s power beneath our feet, and this is geothermal energy, which is generated within the earth. Around two thousand miles below the crust of the Earth, there’s the core where heat is emanating from. If the rocks underground are also heated, they become magma, and this partly melted rock often produces gas bubbles, or they burst towards the surface and form as lava. 

    They often heat steam vents, hot springs, geysers, and underground aquifers, and many companies often use this heat to produce electricity. Various countries often depend on geothermal energy that can be accessed immediately, and they can bring healing and comfort to most people today.

    How Does Geothermal Energy Work?

    Tapping into the sub-surface of the fluids and rocks beneath the crust is possible, and these often result in the release of thermal energy. Underground reservoirs are often dug underground to access the hot water and the steam. It’s often utilized in more than 20 countries, and the Geysers in California is often known to be one of the largest geothermal fields.

    In Iceland, this is also prevalent and has been used since the early 1900s. The country considers itself a pioneer of geometrisk energi where it produces over 25% of the energy from five plants. This is because of the 200 volcanoes and hot springs that are present in its regions and are a great source of electricity.

    What are the Basics of the Electrical Generation?

    Generators are used for the conversion of kinetic energy into electric one, and this is often created through electromagnetic induction. Spinning creates power, and this was discovered in 1832 by Michael Faraday. The movement resulted in different voltages at the two ends of a conductor, or a spinning wire and it resulted in a flow of electrical current. 

    Modern generators are the same, and the rotation of the copper wire and coils has resulted in streams of electrons. Companies are now making them on a global scale, and this is often considered renewable, carbon-free, and sustainable forms of energy. They’re often used in office buildings and to heat homes, and they can only produce around one-sixth of the carbon dioxide compared to natural gas plants.

    Potential production is not intermittent, unlike wind turbines and solar ones. However, there are drawbacks as well, since the carbon dioxide production is lower, the emissions of hydrogen sulfide and sulfur dioxide can be higher. Also, the factories may cause mini tremors in their operating locations, and this is why it’s just limited to the US, Iceland, Indonesia, and Kenya.

    What are the Pros and Cons?


    One of the major things that you can expect with geothermal energy is its reliability because, unlike the ones that harness the sun and the wind, this doesn’t often depend on the weather conditions. It can mean better consistency, and stability, and there are also low operating costs.

    After the set-up is done, there can be minimal fuel requirements, and this can translate into savings when it comes to a household’s utility. Also, these plants have a small physical footprint compared to other types of power plants, making them suitable for areas with limited space.

    On the flip side, one disadvantage is that it's location-specific because not all regions have access to geothermal resources suitable for electricity generation. The upfront costs of drilling and building plants can also be significant, which may deter some investors.

    Despite these drawbacks, the advantages of geothermal energy make it an attractive option for sustainable electricity generation moving forward into the future. You can see more info about geothermal energy on this webpage here.

    What are the Other Options Out There?

    → Solar Power

    Solar Power

    This is one of the most abundant sources of electricity for many people where the panels are harnessing the sun’s rays. This is popular in both residential and commercial settings, and it’s even possible to power up entire cities with these farms. Installations are done on rooftops, and the sun is converted into power through photovoltaic cells. They are also great sources of clean energy because they lack the emission of greenhouse gasses.

    Scalability is possible because the panels can cater to small home installations and utility-scale projects. It’s a great and versatile solution that can be used to meet various needs across different sectors.

    Not only does solar power help reduce the emissions of greenhouse gasses, but it also creates jobs and stimulates economic growth in the renewable energy sector. As technology advances and costs continue to decrease, solar power is becoming increasingly accessible and affordable for everyone. Switching to the panels not only benefits the environment, but also offers long-term savings on electricity bills while promoting sustainability for future generations.

    → Wind Turbines

    When it comes to renewable energy sources, wind power stands tall as a sustainable and efficient option, and harnessing this to generate electricity has become increasingly popular in recent years.

    Wind turbines are strategically placed in areas where there is a consistent flow of wind. As the blades spin, they convert the kinetic energy of the wind into mechanical power, which is then transformed into electricity through a generator. Visit the post here for kinetic energy for more info:

    One of the main advantages of this option is its ability to produce clean energy without emitting harmful greenhouse gasses or pollutants. This makes it an environmentally friendly alternative to traditional fossil fuels.

    However, one challenge with wind power is being intermittent, since no one can control when or how strongly the wind blows, there may be times when electricity generation fluctuates.

    Despite this drawback, advancements in technology have made wind power more reliable and cost-effective than ever before. 

    → Hydroelectric Power

    Water is a renewable energy source that harnesses the power of flowing water to generate electricity and is one of the oldest and most widely used forms of clean energy. By strategically placing turbines in rivers or dams, hydroelectric plants can produce a significant amount of electricity without emitting harmful greenhouse gasses into the atmosphere.

    The process of generating hydroelectric power involves converting the kinetic energy from moving water into mechanical energy, which then turns generators to produce electricity. This reliable and consistent source of power can help reduce people’s dependence on fossil fuels and contribute to a more sustainable future for generations to come.

    While hydroelectric power has its advantages, such as low operational costs and minimal environmental impact once built, it also faces challenges like habitat disruption for aquatic life and potential risks associated with dam failures. Despite these drawbacks, many countries continue to invest in expanding their hydroelectric capacity due to its proven track record in providing clean and reliable electricity.

    Comparison of Costs and Efficiency among Different Sustainable Sources


    When it comes to comparing the costs and efficiency among different sustainable sources of electricity, there are various factors to consider. Solar power is known for its decreasing costs and versatility in installation, making it a popular choice for residential and commercial use alike.

    Wind power has also seen significant advancements in technology, leading to increased efficiency and lower production costs over the years. With vast potential for harnessing wind energy, many countries are investing heavily in wind farms as a critical component of their renewable energy mix.

    Hydroelectric power remains one of the oldest forms of renewable energy, with established infrastructure contributing to its reliability and cost-effectiveness. Despite initial high capital investments, hydroelectric plants offer long-term benefits in terms of low operating costs and minimal environmental impact. 

    Each sustainable energy source has its unique advantages and challenges when it comes to costs and efficiency. Understanding these differences is crucial in developing a well-balanced renewable portfolio that can meet one’s growing electricity needs sustainably. They can also result in cost savings when done right the first time.

    Resource Potential of Geothermal Energy


    Since it harnesses the natural heat from the geysers and volcanoes, as well as heated rocks, it can be tapped as a major source of energy. In 2021 alone there’s around 3,692 MW of electricity produced, and this is expected to grow over the years.

    Projections exist where the plants are known to increase their capacity, and other countries like New Zealand, the Philippines, Turkey, and Mexico are expected to expand their operations. Heat pumps are often the primary method for the direct use of geothermal, and the shallow ground is often enough to serve as a reservoir.

    Heat transfers are possible from the building to the ground, especially during the cooling season and vice versa. Aquacultures, greenhouses, and other industrial processes can also utilize geothermal energy when needed.

    It starts with the development phases, where researchers may drill the crust for generation. Capital costs are about $2500 per kilowatt, and most plants are qualified for a production tax credit. Companies often buy them as part of their eco-friendly projects, and the top users are the Procter & Gamble company, Microsoft, Google, T-Mobile, and Walmart. Consumers are now also opting for greener or more renewable energy, and it’s believed that funding opportunities are on their way for those who want to.
