definition, solar radiation is in fact an electromagnetic wave radiation. This makes solar energy a source of pure energy which has in its content the ability to deliver 100% maximum work (maximum exergy), as referred to in thermodynamics. Therefore, solar energy has the highest potential for producing useful work. Whether an application that uses solar energy as input is of thermal nature or independent of temperature, solar energy can be an ultimate choice for a sustainable source of clean energy. In a
Solar energy is the most readily available energy source in the Earth blessed by nature. The radiant light energy from the sun contains photons which can be utilised by the solar cells to produce electrical power. The solar cells are made up of semiconductor materials. A single solar cell having very low power producing capability and thus we can use large number of cells in series and parallel to produce enough voltage and current. The power produced by the solar cells is directly depend upon the
ultimate source of energy and its availability allows for various ways to be developed so its free energy can be utilised. A major way in which the energy from the sun (often called solar energy) has been utilised is in the aspect of solar cooking technology (Ahmad, 2001), which is available in different types from the relatively cheap ones with low technology to the big expensive ones that can be used in the industrial heating system or cooking for hundreds of people (Otte, 2013). A solar cooking system
major and importance requirement for people all over the word. This is because people must cooked to make sure the food that their take are in safe and free from harmful bacteria. Besides that, wood also is a major necessities for people in rural area in poor countries use for cooking. They cut tree to make a firewood as their energy source of fuel. For the other source like charcoal and gas is very expensive in certain countries. In Africa for example, cooking energy represent the main energy consumption
Introduction The consumption of energy increased significantly in the past century, and with it, the demand for energy supplies increased as well, primarily because the exhaustible sources started to drain compared to its immense need. Therefore, the world was anticipating reliable renewable energy sources, the most common being: 1) Biomass: it relies on organic materials from plants and animals. 2) Hydro-power: that is based on the moving water. 3) Geothermal: using the heat from the core of the
differentials • Design limitations regarding ceiling heights 5.1 PASSIVE DESIGN PERFORMANCE Passive design refers to the use of the sun’s energy for the heating and cooling of living spaces. In this context, the building itself or some element of it takes advantages of natural energy characteristics in materials and air created by exposure to the sun. The importance of passive design is that it can fulfill the thermal comfort, low heating and cooling bills and it also reduced greenhouse gas emissions
helps to overcome this power shortage by using solar power which is a renewable energy source. The solar energy is abundantly available throughout,so the output voltage from the PV panel is not always constant.Thus the input voltage of the PV inverter can vary widely which is quite different from the desirable voltage level.So we go for Implementation of DC-DC converter with isolated coupled inductor by using non-dissipative snubber for solar energy applications. In this project the proposed converter
amount of uranium could produce large amount of energy as compared to oil or gas and also the transportation of uranium is also less expensive. 2. Reliability of power generation is much high than others as if it is functions properly it could operate for 540 days uninterrupted so no power interruptions makes it more stable. 3. No greenhouse gas emission, as the world is working towards no greenhouse effect nuclear energy is the best source of energy for it. 4. The land requirement of nuclear power
Wood/Medium Density Fibreboard (MDF): saves trees • Solar Panel for hot water: alternative, renewable energy. Wind power: alternative, renewable energy. Being implemented in a phased manner at hotels in Chennai followed by Aurangabad and Pune. • Auto Time Management (for lighting, air-conditioning and ventilation fans) through timers and motion sensors: helps conserve energy The above points prove that the hotel is already implementing a lot of energy efficient practices. But since we have adopted the
MOTIVATION a) IMPORTANCE OF AEROSOL STUDY Aerosol in the atmosphere has such types of effects as follows (i) They are respiratory health hazard at the high concentration found in the urban area. (ii) Aerosol scatters and absorbs visible radiation. (iii) Aerosol effect
