Alternative fuel

4.19 Optimization of ship fuel consumption The OPEX of a ship are mainly dependent upon the following factors. - Fuel consumption (FC) of ship’s main engine (ME) - Fuel consumption of auxiliary engines (AE) - The scheduled maintenance expenses - The owner’s everyday expenses While some regard that cost of loading and offloading of natural gas as the operating expenditures of ship. As mentioned by Stopford, M., 2009, Vessel’s fuel bills consume almost 76% of sailing costs, and some other…

of fossil fuels 1. Not renewable energy Fossil fuels comprise of crude oil, coal and natural gas. It is not renewable and cannot be replaced. Plants and animals that existed millions of years ago became buried underneath the Earth’s surface. This formed as the fossil fuels. Since fossil fuels has limited supply, it can’t fulfil the world’s energy demand. Therefore, alternative energy source is needed to replace the fossil fuels. 2. Emission of carbon dioxide Combustion of fossil fuels…

temperatures is to exchange and recycle conventional sources with alternative ones that have comparable or better performance, but do not emit carbon dioxide. Once the year 2050 decides to shine upon us, roughly one-third of the earth’s energy will have to be from alternative energy who says? British Petroleum and Royal Dutch Shell, which happen to be two of our planets’ largest oil companies. Climate change, population growth, and fossil fuel depletion mean that renewables will need to play a…

Current Knowledge on the Problem Nowadays, people use fuel as a source of energy which helps them improve their economic well-being and living status. However, its usage has come with a cost because its burning and continued popularity is a major factor contributing to global warming (IPPC). It also has a negative impact on the economy. In its composition, only 565 gigatons out of 2765 of carbon dioxide contained in the fossils is burnt before its negative effects on the globe turn irreversible…

Today, we are facing the environmental crisis of global warming. A major factor that is contributing to this is the use and burning of fossil fuels such as coal, natural gas, and oil. Through the process of coal burning, Carbon Dioxide is formed as a result, which is one of the major causes of the Greenhouse effect. With the Greenhouse effect, the Earth’s average temperature rises, causing ice caps to melt, which is an effect of global warming. To put a stop to this, our population needs to…

Most people do not think about what they are breathing in every day they’re outside. Chances are you did not realize you are breathing in carbon monoxide, a clear gas that blocks oxygen to the brain and can kill a human. With over 1 billion cars on the road every day, the impacts on breathing are astronomical. Millions of Americans everyday breathe in the toxic gas that is emitted from the tailpipes of cars, planes, trucks, buses etc. And slowly it is taking its toll, causing diseases,…

With the United States being the second largest contributor of burning fossil fuels in the world, a new source of energy is overdue. About 86% of the country’s types of energy sources originate from fossil fuel consumption and other closely linked greenhouse gases. Some of these emissions include carbon dioxide, methane and other harmful gases. Without an alternate source of energy the atmosphere will continue to trap higher amounts of toxic gases and eventually won’t be capable of providing…

has damaged the Volkswagen reputation. However, has this event affected the popularity of diesel vehicles as a whole? With the increased concern for the environment and a higher interest to drive more fuel-efficient vehicles can diesel vehicles make a comeback for the 21st century as an alternative to gasoline, electric, and hybrid vehicles? Research shows that diesel vehicles are a viable option for twenty-first century car shoppers. Recently Volkswagen has made headlines in the news after…

the concerns that need to be taken into consideration when deciding whether or not to use solar energy as an alternative solution to fossil fuels such as coal, petroleum, natural gas and nuclear energy for our energy consumption. 2.1 Impact on resources Many non-renewable resources are being extracted to the point of exhaustion without any consideration to the fact that these fossil fuels may not restore themselves in this century or at all. Coal, which is thought to be the most widely…

environmental groups, Mr. Hunt is required to reconsider his approval on coalmine in Carmichael. Nowadays, climate change is a hot topic in the world. Scientists prove that the major cause of climate change is human activities through burning of fossil fuel and deforestation. These activities increase greenhouse gas in the atmosphere, which global warming articulates every year. Climate change is one of the most significant drivers in change in social-ecological system in coastal areas(Evans et…
