Geothermal energy is energy generated from heat stored in the Earth. It was first used centrally in Italy and is now used for electricity generation in power plants and directly as geothermal heat pumps for heating and cooling. While it provides cost savings, environmental, and economic benefits, geothermal energy has disadvantages in that it is not widespread, installation can be costly, reservoirs can be depleted, and it is only suitable for certain regions.

Geothermal energy works by pumping cold water underground where hot rocks heat the water into steam, which is then used to generate electricity. It is renewable with no pollution, but is only viable in few locations and can be costly to implement due to deep drilling required.
Comparison Between Renewable Energy and Fossil Fuels
Fossil fuels (coal, oil and natural gas) are still essential for transportation, electricity generation, heating, plant operations, and so much more. But they are also the main source of CO2 emissions and, unlike renewable energies, are produced from exhaustible – albeit still vast – reserves.
8 sun as an energy source 2015
The document discusses the sun as an energy source. It explains that the sun's angle changes with the seasons, causing variations in day length and seasonal temperatures. It also notes that sunlight is more spread out when hitting the Earth at shallower angles, covering more area with the same energy. Additionally, it provides guidelines for optimal solar panel orientation for different purposes, such as maximizing energy in summer versus winter.
Solar concentrator
This document summarizes a solar concentrator power plant. It explains that solar concentrator systems use mirrors or lenses to concentrate sunlight onto a small area to generate heat, which is then used to power steam turbines and generate electricity. The first concentrated solar power plant was built in Italy in 1968. Solar concentrators work by using Fresnel lenses to focus sunlight onto a central receiver. Future studies project that concentrated solar power could provide 25% of the world's energy needs by 2050 with increased investment. Tower designs aim to efficiently collect and store thermal energy to generate electricity even when the sun is not shining.

Solar Power Tower
The document discusses solar power towers, which use an array of flat, movable mirrors called heliostats to focus sunlight on a central collector tower. The concentrated sunlight heats a fluid in the tower that is used to generate steam and power a turbine, producing electricity. Several early solar power tower projects from the 1980s-1990s are described that varied in size from 0.5-10 MW and used different heat transfer fluids and storage media. The technology has advantages of being easy to operate, environmentally friendly, and having falling costs as renewable energy.

Solar energy originates from the thermonuclear fusion reactions of the sun. It represents the entire electromagnetic spectrum that reaches the Earth. Some key advantages of solar energy are that it produces no pollutants, and the energy reaching the Earth each day is greater than all the fossil fuels on the planet. However, solar energy is intermittent and diffuse, requiring technologies to concentrate and store it. Various technologies can harness solar energy for heating water and living spaces, as well as generating electricity through solar thermal power towers and dishes/troughs that focus sunlight. Overall, solar energy represents an enormous renewable resource that can significantly reduce dependence on fossil fuels.

Solar Tower
The document discusses a proposed solar tower project in Australia that would use solar energy to power homes. The solar tower would have a base 3.5 miles in diameter and stand 1000 meters tall. Air heated by solar collectors under the tower would rise and power 32 wind turbines, generating enough electricity for 200,000 homes. The project aims to provide renewable energy and reduce greenhouse gas emissions.
Solar energy
Solar energy is energy from the sun that can be used to provide heat, light, and electricity. It has been used for thousands of years but is now also used to generate electricity, including in remote areas and space. India has significant solar resources and has initiatives to increase solar power production, with a target of 100GW by 2022. Several large solar parks and projects have been implemented, such as the Kamuthi Solar Power Project, which at 648MW is one of the largest single location solar projects in the world.

Nuclear energy comes from splitting atoms through nuclear fission, which creates heat to boil water into steam that turns turbines to generate electricity. It is considered more environmentally friendly than fossil fuels as a renewable energy source, but it uses rare uranium and risks radiation leaks from accidents that could cause power plant explosions.
SOLAR UPGRADE TOWER
This document discusses solar updraft towers as a renewable energy technology. It begins by outlining current energy crises due to depletion of non-renewable resources and introduces renewable energy sources including solar energy. It then describes the key components of a solar updraft tower - the collector, chimney/tower, and turbine - and how they work together to convert solar energy into kinetic energy to power a turbine. Benefits are that solar updraft towers provide continuous renewable energy without requiring cooling water or producing greenhouse gases. However, they do require large areas of land. The conclusion advocates for solar updraft towers as a technology that can provide simple, reliable solar power accessible to developing nations.
Solar thermal energy
Solar thermal energy harnesses solar energy to generate thermal or electrical energy. It uses solar collectors to capture sunlight and convert it to heat. Collectors are classified by temperature as low, medium, or high. Low collectors heat pools or air, medium heat water or air for homes/buildings, and high concentrate sunlight for industrial heat up to 300°C or electricity generation. Solar thermal was first used in 1910 in the Sahara but later abandoned until being revisited. It works by capturing sunlight through collectors using the greenhouse effect to heat a fluid for applications like water and space heating, or pools. Collectors have a glass cover and dark absorber plate that heats a fluid circulating through pipes.
SOLAR UPDRAFT POWER PLANT
The document describes the working principles of solar updraft towers, which use solar heating to create an updraft that spins turbines to generate electricity. Solar updraft towers consist of a large glass roof that heats the air below it, creating an updraft that is channeled up a tall, cylindrical tower and drives turbines at the base. The towers can operate 24 hours a day using thermal storage and produce electricity on a large scale. Previous prototypes demonstrated the viability of the technology and further optimization is possible.
Solar furnaces
Solar furnaces use an array of mirrors to concentrate sunlight and produce extremely high temperatures. They have existed since the 18th century but were first developed as a furnace in the 1940s in France. There are two main types - direct and heliostat - and they work by using plane and parabolic mirrors to focus sunlight at a focal point. Solar furnaces can be used for applications like generating steam power, cooking, drying foods, and melting metals. In Africa they have potential uses for cooking, agriculture, industry, and reducing environmental impacts. However, widespread commercial use of solar furnaces has been limited by their high costs and requirement for large spaces.

Solar energy
Solar energy is radiant light and heat from the sun that is harnessed using technologies like solar heating, photovoltaics, and solar thermal energy. It is categorized as either passive solar techniques that don't require equipment or active solar techniques like solar panels and concentrated solar power. The potential for solar energy depends on factors like geography, time of day, cloud cover, and available land area. Examples of large solar energy projects highlighted include a planned sustainable education building in the Netherlands with a large solar roof, NREL's zero energy research facility in Colorado with transpired solar collectors, and Welspun's 150 MW solar power plant in India, one of the largest in Asia.

For each application, it describes the basic process and components involved. It also includes diagrams to illustrate how some of the solar energy technologies work, such as solar water heating systems and solar air conditioning.
geothermal energy
Geothermal energy is heat extracted from below the earth's surface that can be used for heating, cooling and bathing. It is extracted from geothermal fields located 5000-10,000 feet underground, where the heat flows through surface pipelines to separators using either standard, low, or high pressure crystallization. Geothermal energy has advantages of being renewable, non-polluting, and requiring minimal land compared to other power plants, but has disadvantages of geothermal fields not being universally available and having high initial capital costs.
Redesign and Fabrication of Solar Power Tower using CAD and FEM Analysis
The solar power tower (also known as 'Central Tower' power plants or 'Heliostat' power
plants or power towers) is a type of solar furnace using a tower to receive the focused sunlight. It uses
an array of flat, moveable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the
target). The high energy at this point of concentrated sunlight is transferred to a substance that can store
the heat for later use. The more recent heat transfer material that has been successfully demonstrated is
liquid sodium. Sodium is a metal with a high heat capacity, allowing that energy to be stored and drawn
off throughout the evening. That energy can, in turn, be used to boil water for use in steam turbines.
Water had originally been used as a heat transfer medium in earlier power tower versions (where the
resultant steam was used to power a turbine). This system did not allow for power generation during the
evening

Solar energy, collection and applications
Solar energy comes from nuclear fusion reactions in the sun. About 30% of the solar radiation that reaches Earth is absorbed by the Earth's surface, with the rest reflected or absorbed by the atmosphere. All life on Earth depends on solar energy through photosynthesis.
The rate at which solar energy reaches the top of the atmosphere is known as the solar constant, which NASA estimates to be about 1.353 kilowatts per square meter. Instruments like pyranometers and pyrheliometers are used to measure incoming solar radiation, while sunshine recorders measure the duration of bright sunshine.
Solar collectors, such as flat plate collectors and evacuated tube collectors, are devices that collect and concentrate solar radiation for uses like heating water

sources of energy
Energy is defined as the ability to do work and exists in different forms that can be converted from one to another. Energy sources can be renewable like wind and solar that can be replenished, or non-renewable like fossil fuels that are limited. Fossil fuels are a conventional energy source but have disadvantages like pollution and contributing to climate change. They are not renewable as once burned, there is no more.
Geo thermal energy
This document discusses geothermal energy, including what it is, where geothermal reservoirs can be found, how the heat energy is extracted and used, and electricity generation from geothermal sources. It notes that geothermal energy comes from heat within the Earth and can be accessed from areas with geysers, hot springs, volcanoes and hot mud pots. Extraction methods include using hot springs directly or pumping hot water and steam to the surface. Geothermal heat is used for district heating, greenhouses, industry and electricity generation in dry steam, flash steam and binary cycle power plants. The document outlines geothermal energy potential and some pilot projects in India as well as advantages like being renewable but also challenges like
geothermal energy
Geothermal energy harnesses the natural heat from within the Earth as a renewable energy source. It can generate electricity 24/7 year-round with minimal environmental impacts. Geothermal reservoirs reach temperatures over 700°F and are found at locations with geysers, hot springs, volcanoes, and boiling mud pots. 24 countries currently use geothermal energy, with the first commercial plant opening in Italy in 1911. Direct uses of geothermal heat include heating buildings and greenhouses. While installation costs are high, geothermal electricity production has low operating costs and becomes very cost competitive over time.
Geo thermal
Geothermal energy is a renewable energy source that harnesses heat from within the earth. It can be extracted from geothermal reservoirs found in areas with geysers, hot springs, volcanoes, and boiling mud pots, where hot water and steam are trapped in porous rock. This heat energy can be used directly, such as for heating buildings and greenhouses, or indirectly for electricity generation in dry steam, flash steam, or binary cycle power plants. While geothermal energy has advantages of being continuously available and having little environmental impact, development is limited by high upfront costs and the risk of reservoirs running dry or releasing harmful gases.
GEOTHERMAL POWER PLANT AND ITS INDIAN SCENARIO

geothermal ppt.pptx
Geothermal power plants tap into the Earth's natural internal heat to generate electricity. They work similarly to conventional power plants by using geothermal heat instead of combustion to power steam turbines connected to generators. There are three main types - dry steam, flash steam, and binary cycle plants - which differ based on the temperature of the geothermal resource and method used to power the turbine. Geothermal energy is a renewable resource with advantages of being constant and not requiring fuel, but also has disadvantages of being location-restricted and carrying earthquake risks. It represents a growing industry that could help transition energy supplies to more sustainable sources.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
