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.
Fossil fuels are not healthy for the environment. Energy subsidies seek to strengthen the idea of moving toward renewable energy sources. Historically, the United States energy sector has mainly depended on natural gas and petroleum, whose emissions are harmful to the environment. In recent years, especially in light of global warming, the idea of renewable energy systems has quickly grown. Energy subsidies, in this case, are utilized to diminish contamination, including distinctive discharges, and to satisfy universal commitments, like the Kyoto
In California, there is a renewable energy mandate in place that requires at least “33 percent of the state’s electricity [to] come from renewable [sources] by 2020” (Levitan 1). If not, they will have to face the consequences in the forms of fines. Since many companies will not build solar plants due to the relatively expensive costs, “loans from the Department of Energy” allows them to get constructed without companies to take a huge hit on their finances (Levitan 1). This allows for what may be an expensive endeavor to be easily paid for. By having these renewable energy mandates, it forces certain states to have their electricity generated by renewables, which is a great start for the United States to turn towards clean energy.
Abstract In today’s energy driven world, fossil fuels constitute the majority of our fuel resources. Burning of fossil fuels at such an enormous rate has increased the level of carbon dioxide in the atmosphere. Such high level of carbon dioxide emission into the atmosphere has started to take a toll on the delicate balance of gases in the atmosphere. There are efforts being made to develop a method of carbon sequestration that will effectively convert carbon dioxide in to carbonate minerals using alkaline earth oxides like calcium oxide (CaO), magnesium oxide (MgO). Since the start of the world mineralization has taken place naturally and at large scale but the naturally occurring mineralization reactions are too slow to balance out the high
Over the past half-decade, the world has known a near-exponential increase in the consumption fossil fuels. It plays a quintessential role in the proper functioning of the globe. However, over the past few years, oil reserves have been depleting at a quick rate. There will be a day when there will not be any fossil fuels left to assuage the energy needs of the world. There is currently a few alternative resources lined-up but the most promising for fossil fuels to pass the torch to seem to be nuclear energy.
RECENT ADVANCEMENTS IN LITHIUM BATTERY In this assignment I am going to discuss the different properties and advancements in lithium batteries. I have below listed the different aspects and along which the researches that have been done to improve the lithium battery output. Future batteries, coming soon: charge in seconds, last months and power over the air While electrical devices are becoming smart and even more advanced, they are still limited when it comes to power and battery. The battery has not advanced in decades but we are on the verge of a power revolution. Big technology companies, car companies and smartphone companies are well aware of the limitation of the currently
They are terrible for animals, humans, and the atmosphere alike. The debate on climate change has impacted the environmental activist community heavily. They believe the toxins released into the atmosphere by fossil fuels are warming the earth incrementally, which is consequently melting the polar ice caps. When temperatures rise and ice melts, the oceans’ water levels increase, which is happening more rapidly than ever before (Glick 1). Our planet could potentially flood if this trend does not stop.
Nobody really noticed things about biomass power until recently, it started to produce large amount of energy comparing to wind energy and solar energy. Biomass fuels are the plant material and animal waste, it is also the oldest source of renewable energy. There are sustainable low-carbon biomass power and without sustainable biomass power. Sustainable low-carbon biomass power can provides more energy and can avoid from huge impacts of global warming. On the other hand, low-carbon biomass power without sustainability are more expansive and took longer time to clean the energy economy.
One of the major concerns in the power sector is the day-to-day increasing power demand but the unavailability of enough resources to meet the power demand using the conventional energy sources. Demand has increased for renewable sources of energy to be utilized along with conventional systems to meet the energy demand. Renewable sources like wind energy and solar energy are the prime energy sources which are being utilized in this regard. The continuous use of fossil fuels has caused the fossil fuel deposit to be reduced and has drastically affected the environment depleting the biosphere and cumulatively adding to global warming. Solar energy is abundantly available that has made it possible to harvest it and utilize it properly.
The main biomass fuel that is well known is wood and byproducts. The min method to produce biomass energy is from the thermal treatment (i.e. incineration, gasification and pyrolysis), biomedical processing and chemical treatment. 1.2 Why solar energy Project related to solar energy is selected here because it has too many advantages over other conventional and renewable energies some of them are stated here 1.2.1 Renewable energy Solar energy is a renewable energy source this means that we cannot run out of solar energy as conflicting to non renewable energy source. 1.2.2 Abundant The prospective of solar energy is afar thoughts.
