The burning of the fossil fuels is also the main contributor to global warming. Fortunately, alternative sources of energy that are environment friendly and also renewable are available to use. Biogas, an alternative source of energy, can be manufactured by humans by using human and animal waste. Windmills, Solar energy, Geothermal and Hydroelectric are all alternative and renewable sources of energy that are obtainable to in this modern era. This essay will be centred on how to harness those alternative sources of energy effectively.
Fossils fuels with compact chemically stored energy only became intensively used in the early eighteenth century, using mainly the burning of coal for steam engine, paving way for the industrial revolution. Fossil fuels used were initially
(Transition) Body I. Fossil fuel and the alternatives A. Fossil Fuels 1. Merriam-Webster dictionary defines fossil fuel as : A fuel (such as coal, oil, or natural gas) that is formed in the earth from dead plants or animals” B. Hydrogen 1. One of the most abundant elements found on earth. But rarely found by its self. It is most commonly refined from water C. Ethanol 1.
Year 12 HSC Chemistry Notes (Conquering Chemistry) Module 1 – production of Materials Ethylene, polymers and ethanol * Fossil fuels – energy rich substances formed in the Earth’s crust under intense heat and pressure millions of years ago. Originally remains of marine organisms, they were converted into petroleum that is trapped near the Earth’s surface. Fossil fuels can be extracted and refined to provide energy, and the building blocks of crude oil can be used to create numerous materials for human use e.g. ethylene. * Petroleum – mixture of hydrocarbons, consists of liquid crude oil and gaseous natural petroleum gas.
Mitigation Strategies and Solutions Energy Conservation SCI 275 Environmental Science Mitigation Strategies and Solutions Everything in the world uses energy it just depends on what form or what kind is being used. There are two different types of energy there is the nonrenewable kind and then there is the renewable resources that we need to keep. The difference between the two is that nonrenewable resources are like oil and coal that cannot be just made up to suit our daily needs, it takes lots of time and money to get these resources. Then there is the renewable resource like electricity that we can get from the sun, wind power and also biomass fermentation that uses waste to produce energy as well. Everything in the world living and nonliving are affected by the consumption of energy for example when using a electric hybrid vehicle we use less gas but then we use more electricity; we give up one resource for the use of another.
Introduction Coal is a variety of solid, combustible and organic sedimentary rocks formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years (IEA, 2017). Around the world, requirements for energy and electricity are met by fossil fuels amongst which coal is the most abundant and broadly distributed. It is the most common fuel choice because it is a secure and low cost energy source and is relatively easy to mine, ship, and store. Coal is the second source of primary energy after oil and is mostly used for power generation. Over 40% of worldwide electricity is produced from coal (IEA, 2017).
When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But humans have burned so much
Fracking is bad for the environment. People still need natural gas or oil to live their life. It will take time to get all of the bugs worked out of fracking. Fracking companies are using the new technology to insure the protection of the environment. Fracking is a cheaper way of obtaining gas.
We also can produce diesel and gasoline for our nation’s income. The fuels produced by the coal liquefaction can be used to power vehicles, heat homes and run factories and many more. There are two main stages in the coal liquefaction process. Coal gasification and gas to liquid (GTL). In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit.
The plasma furnace is the central component of the system where gasification and vitrification takes place. Plasma torches are mounted at the bottom of the reactor, they provide high temperature air (i.e., almost three times higher than traditional combustion temperatures) which allow for the gasification of the waste materials. The gas produced in the furnace system is referred to as synthesis gas. This gas then enters the synthesis gas cleaning system. Gas cleaning refers to the process of removing acid gases, suspended particulates, heavy metals and moisture from the synthesis gas prior to entering the energy recovery system where power, steam and synthetic fuels can be obtained.
