Some situations include things like porcelain, cup, and the majority materials. Air, nitrogen as well as sulfur hexafluoride would be the three most often utilized gaseous dielectrics. • Industrial coatings for instance parylene provide a dielectric hurdle between the substrate and its particular surroundings. • Mineral oil used substantially inside electrical transformers like a liquid dielectric and also to aid in cooling. Dielectric fluids with greater dielectric constants, for instance electrical grade castor oil, are often utilized in higher voltage capacitors to aid avoid corona eliminate and also boost capacitance.
Argument Essay Research Claim: Alternative fuels are necessary, but we are still trying to come up with alternative fuels that don’t create greenhouse gas when produced or used, is reliable and better than gas or oil, and is cheap to use. Reason 1: Pollution/global warming According to the article Ethanol Increases Pollution, “Hyped as an environmentally friendly fuel, ethanol actually increases pollution, argues Sasha Lilley in the following viewpoint. Although ethanol-based fuel is cleaner, ethanol processing plants, which are powered by coal, emit greenhouse gases that contribute to global warming” (Sasha Lilley). Ethanol itself is environmentally friendly but the ethanol plants that makes ethanol also makes greenhouse gas, which can increase global warming which is why we need to switch to better fuels or find a better way to create ethanol. To successfully have hydrogen as a fuel source, it needs to have no greenhouse gas produced while it is being produced or used.
For example, storage would improve the performance of a power generating plant by load levelling. The higher efficiency would lead to energy conservation and improve cost effectiveness. Some of the renewable energy sources can only provide energy intermittently. Two particular problems of thermal energy storage systems are the heat exchanger design and in the case of phase change materials, the method of encapsulation. The heat exchanger should be designed to operate with as low a temperature difference as possible to avoid inefficiencies.
Environment- The replacement of fossil fuels with renewable energy (UCSUSA, 2013) will cause a decrease in CO2 emissions which will decrease pollution. By using renewable energy sources like solar energy, we also reduce our dependence on fossil fuel gas and oil reserves, which are becoming more expensive and difficult to find. It also reduces our dependence on imported fossil fuels, improving our energy security. Economic- Renewable energy development outperforms fossil fuels (UCSUSA, 2013) in two important ways when it comes to driving job growth, first of all renewable energy development is relatively labour intensive, so it creates more jobs per dollar invested than fossil fuel resources and Installing renewable energy facilities uses primarily local workers, so investment dollars are kept in local communities. Local landowners benefit from renewable energy development.
Angel Hsu A block Solar Energy 12/22/2015 “Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy resources, like solar power.”(Jimmy Carter, televised speech,1977) Just like what he said, we should develop other energy than fossil fuel because we will run out of it some days and fossil fuels are the main reason of global climate change. Global climate change is a very serious problem that we must pay close attention to. The main reason that causes climate change is that there are too many carbon dioxide in the atmosphere. If the temperature keeps getting higher and higher, there will be many problems that can cause great damage to us and the environment. If we don’t replace fossil fuels with other clean energy, our Co2 level will be as many as the time of the dinosaurs and we don’t know what will our lives be if this really happened.
Carbon energy is energy where fossil fuels are burned to create energy. The problem with burning these fossil fuels is that it produces greenhouse gases that destroy the ozone layer, as well as contributing to global warming. These gases are called carbon dioxide and sulfur oxide. These gases are known to cause respiratory issues within animals and people. Another issue with carbon energy is the people working
Friendliness of solar energy to the global environment can be explained in term of global greenhouse effect, and byproducts released. Solar energy along with other renewable energy plays a big role in minimizing greenhouse effect. Most of the traditional energy generating system affects local climate and interferes with Earth’s overall heat balance due to the net addition of heat into the atmosphere during electric generation process (Aubrecht, 2006). Combustion of traditional sources of energy like fossil fuel increases the amount of carbon dioxide (CO2) in the atmosphere which induces a heightened greenhouse effect and warming of the earth (“Renewable Energy”, 2015). In the other hand, Aubrecht (2006) stated that all solar energy devices redistribute thermal energy from one place to another and do not release additional thermal energy to the atmosphere.
It makes use of a certain thermal property that varies with temperature. 4.1 Transfer of thermal energy: Thermal energy is always transferring from a place with high temperature to a place with low temperature. So we can say that the direction of the thermal energy transferring is from warmer place to a colder one. The main ways for transfer of thermal energy are: • conduction • convection • radiation Conduction: When we have a direct contact between at least two objects with a different temperature. The warmer objects transfer energy to the colder object and because of that it occurs: the temperature of the colder object became to rise when at the same time the temperature of the warmer object became to decrease.
