Throughout history, society has been looking for ways to increase renewable energy to provide better resources to replace fossil fuels to reduce carbon footprints. The earth is a great source of natural energy therefore thermal energy is one of the most abundant resources. There are many types of renewable energy, such as sunlight, wind, rain, tides, waves, and geothermal heat. Geothermal heat renewable energy converts natural heat into electricity resources. Geothermal energy represents the inner heat of the earth’s core. Geothermal energy is mainly produced by decays of radioactive elements in the mantle and the center of the earth’s layers. Heat is constantly flowing from the Earth center to the surface creating a great source of natural energy. These geothermal power plants drill wells into geothermal tanks to transfer hot water and steam from the earth’s core to the surface. One great advantage of geothermal energy is that using the resources of water and steam, you are able to reuse and pump back the supplies into the ground. Another perk of using geothermal energy is that the energy is clean. Geothermal energy is environmental friendly because the power plants don’t use fossil fuels.

What are some forms of energy storage? What are the benefits of these? The forms of energy storage are superconducting magnetic energy storage, compressed air energy storage, electrochemical energy storage (batteries), pumped hydroelectric storage, thermal energy storage, and kinetic energy storage. The benefits are solar and wind can be intermittent; if there is too little of one energy storage and large coal/nuclear plants are more sufficient with constant energy output, if there is too much forms of energy storage.

help to reduce required energy and thermal pollution. This paper presents an overview of research

Thermochemical heat storage can be physical (sorptive) or chemical based on the material used. The storage system which does not involve the production of new compound is called sorptive storage while those which involve formation of new compound are called chemical storage. The successful thermochemical storage system is sorptive storage system that works on utilizing the heat of reaction enthalpy. Thermochemical storage has considerable benefits when compared to sensible and the latent-heat thermal energy storage systems since it is easily controllable which prevents the heat loss. The features of sorptive heat storage technology enables the implementation on a large scale.

The Peltier-effect has been now known for 180 years. But only recently has it developed more practical uses. Now it is not only indispensable to send a spaceship to Saturn and to speed up the central processing unit of your PC. You may even find one in your lunch box! In this module, you will do simple experiments with a small peltier device. You will find out how the three different applications of the device are related. You will look at the flows of energy and realize analogies to quite different engines such as airplane engines and those in Refrigerators. The history of thermoelectric effects shows how closely related science and technology are. And you will see that scientific development sometimes goes strange ways. All modern science is quantitative. It is not enough to know whether a device works “in principle” or if it might solve some practical problems. One has to show how well it works. Science is also a network of links between different fields, and this web needs quantitative knots to hold. You will therefore carry out quantitative measurements with Peltier devices.

In brewing industry, 80% of overall final energy consumption is used in the form of thermal energy where solar thermal can be used for brewing processes as below: steam generation, malting process, stopping germination of grains, air cooling, conservation with hot air, power supplying of washing machines, wither and kiln processes. Malting plants and breweries consume heat for their thermally driven processes at temperature level ranges between 25°C to 120°C. It seems feasible to supply heat at this temperature level which is not higher than the actual amount required but in reality the it is often decided by the consumer which needs the highest temperature. The integration of solar renewable energy system is necessary to reduce the exergy losses and CO2 emissions [17,21,24,25].

Energy storage, in combination with innovative real time dynamic pricing and renewable electricity generation, can be utilized to mitigate grid power disruptions, inefficiencies inherent in the current supply and demand of electricity to and from the grid, and limit the waste of elec- tricity generated from renewable

Thermal energy storage (TES) system store excess thermal energy with different applications and materials and release it for later use. [1] For instance, TES systems is a available means to balanced energy demand between day time peak hours and night time lower usage of energy. Specially, with the applications such like solar

Copper and copper alloys are widely applied in instruments and machines due to its high strength, excellent properties of thermal conductivity, and low price.With the rapid development of modern industry, people put forward higher demands for Cu alloy.The demand is in both terms quality as well as quantity, for the latter part research has been focused on the improvements in extraction processes, mining from ores than further extraction of copper to its purest form to increase productivity in measures of quantity. Also from a long time quality of metals is also a big challenge for a metallurgist. Quality measured in many terms like wear resistant, corrosion resistant, ductility, conductivity(both electrical and thermal), durability, abrasion etc. But as a metallurgical engineer our focus is on improving the mechanical properties like hardness, yield strength, ductility, corrosion resistance (environment specific), thermal properties and microstructure. It has been observed that cryogenic treatment can play the effects of increasing mechanical properties and dimensional stability.

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.

The energy content of solar radiation can be used as light, heat and electricity. This diversity means that solar power is an option different power systems important food worldwide. In fact, interest in solar power systems has been increasing in recent years worldwide. This interest to several factors, such as environmental awareness, effort should be to minimize the dependence on non -renewable fossil fuels countries and international agreements that require the reduction of greenhouse gases in the atmosphere of the earth. Heat storage technologies, systems and applications are studied in the field of solar energy. One way to collect and store solar energy by using solar ponds can be used to provide thermal energy for various applications, such as process and space heating, water desalination, refrigeration, drying and power generation. Thermal energy storage has always been the most important energy storage option. Solar ponds are a classic application of thermal energy storage and efficiency essentially depends on the storage capacity of the fluid, Thermo physical properties of pond conditions and surroundings. Recently, attention has been paid to friendly sources to the environment, sustainable energy, such as solar energy. In this respect, solar ponds seem to be a potential for the application method. In this respect, solar ponds seem to be a potential for the application method.

Phase change materials are widely used source of thermoregulation (TM) systems and in latent thermal energy storage (LTES). PCMs capability to absorb and release large latent heat during phase change transition processes provides a wide range of phase change temperatures for thermal management systems. The incorporation of PCMs can achieve the same or even better performances with a smaller volume. PCMs can meet the thermoregulation requirements of various applications. Currently, the low thermal conductivity of PCMs (usually less than 1 W mK−1) greatly limits their heat dissipation performance in thermal management applications. Currently main focus of research is to increase the thermal conductivity of the PCMs. In this regard different kinds of materials such as metal and carbon composites with PCMs are produced. The intensive experimental and theoretical investigation are made to improve the performance of PCMs. This paper discusses in detail the fabrication and thermal conductance measurement techniques, and mathematical modeling of PCMs composites. Moreover applications of PCMs in TM and LTES system are also mentioned with examples.
