Solar distillation uses, in common with all distillation processes, the evaporation and condensation modes, but unlike other processes energy consumption is not a recurrent cost but is incorporated in the capital cost of the solar collector. Saline water is filled in the black painted basin of the solar still. This is enclosed in a completely air tight surface. A sloping transparent cover is provided at the top. Then solar radiations are allowed to fall on it.
High-volatile bituminous coal due to its high volatile matter content generates high pressure during carbonization which is detrimental to the coke oven walls (Nasirudeen and Jauro, 2011). A range for coking coal is 27.5 – 31.5 % volatile matter. It is one of the most important parameter used in ISO classification of coals. The volatile matter indicate coke yield on carbonization process, which provide basis for its marketability as well as for establishing burning characteristics of coal (Adeleke et al., 2007). Based on the plastic properties of the coal samples, it is observed that the volatile matter of the samples increases inversely with temperature range and maximum fluidity.
Why Wave Energy is a Solution to Global Warming & Types of Wave Technologies Used Global warming is a huge issue nowadays as the carbon dioxide released into the atmosphere increases higher and higher each year. (Graph 1) Consequences we face include dramatic climate changes, rising sea level, dirtier air, and a lot more negative effects that are slowly destroying the planet and the atmosphere. It is predicted by Stephen Hawking that there are only 100 years left before the Earth hits doomsday (Galeon, 2017). In graph 2, you can see that most greenhouse gases came from human’s daily usage of electricity, which is 29% of all sources. We can decrease the amount of greenhouse gases by using other types of energy and different energy sources.
Which two renewable energy forms did you choose? The two energy sources I choose were Solar and Wind. Solar energy is gathered by harnessing the suns rays via PV panels. "Solar photovoltaic (PV) is the main solution used today, involving the use of PV panels that generate electricity when exposed to the sun"(Ahmed, R. A., 2009). These panels trap the suns rays and convert them to energy that can be used instead of the traditional fossil fuels.
However, driven by the environmental impact that it causes, new sources of energy are increasingly becoming implemented especially in developed Countries. On the other hand, strong evidence suggests that becoming too reliant on natural gas poses numerous and complex risks, including persistent price volatility and rising global warming emissions. (The Natural Gas Gamble. A Risky Bet on America's Clean Energy Future, 2015) From an International perspective, coal is one of the major raw materials that use maritime logistics and a complete shift of energy source would have a huge impact in the industry. A total shift would mean extremely expensive investments in ports to adapt or change its facilities to support this new material.
Ancient civilization used solar energy for various purposes. Because of the above mentioned advantage the photovoltaic system is growing exponentially worldwide. It is recognized as a promising source of renewable energy. Majority of nations have installed the grid connected photovoltaic system to provide alternate source of energy. Of course, the main drawback of the grid connected photovoltaic system is variable irradiance and ambient temperature So it must be supplemented by the additional technology to supply the demand curve.
However, the burning of fossil fuel produces greenhouse gasses primarily carbon dioxide that has an advent effect on the environment in recent decade. The excess of the greenhouse gasses in the environment has led to global warming which in turn, has become a common discussion during global forums. According to report “Inventory of U.S Green House Gas Emission and Sinks 1990-2011” from US Environmental Protection Agency (EPA), transportation released 28% of the total gasses emitted in US out of total of 6,702 metric tons of CO2 released in 2011. The subsection consists of motorcar, motorcycle, trucks, airplane and etc. Figure 1.1: Total U.S. Greenhouse Gas Emissions by Economic Sector in 2011 (EPA, 2013) It is the second highest among the entire sector that includes electricity, agriculture, industry, and residential.
1. Introduction Currently, the global need for energy is far surpassing the capacity of the world to produce enough energy to meet such needs, even with the use of our current source of electricity, namely coal. Not only are fossil fuels limited in their supply but they also deliver a great deal of polluting waste, thus rendering this method of generating electricity not sustainable. Furthermore, the
ABSTRACT: “ENERGY DEMAND” is one of the major threads in our country at present situation. In order to meet the energy demand, usage of Renewable Energy is the only alternate solution. This paper deals with the new method of harvesting solar energy with the help of solar panel. The new method deals with direct conversion of heat into electricity by means Thermo electric conversion (SEEBECK EFFECT) so that along with light energy from the sun, heat energy is also absorbed by the solar cell and converted into electricity. Thus with the single panel we can generate more amount of electricity, cost of generation is reduced and efficiency of solar panel is also increased.
• Battery – It store the energy for supplying to the appliances when there is a use. • Load –The electrical appliance that is connected to a solar PV system such as lights, fan etc ( It may be Ac or DC) . ADVANTAGES • Solar power i.e SPV system & solar concentrating system is produced in ecofriendly friendly manner. • Solar pv panel do not emits any waste or
