Alternative fuels‚ also known as non- renewable sources‚ are substances that can be used as fuels‚ other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil)‚ coal‚ propane‚ and natural gas)‚ and nuclear materials such as uranium. [ 1] The fuels we use now are finite‚ meaning they have a limited life expectancy. This along with the toxic waste they produce has made environmentalist and government officials alike take precautionary steps so that we do not

Dependency of Fossil Fuels The flip of a switch‚ turn of a key‚ or the press of a button is all it takes to power up almost everything today. One simple motion holds the key to our future and unlocks our past‚ but at what price? With sources that were once thought to be endless‚ energy consumption and its byproducts has now become a front runner among debates. A far sight from the campfire and miles away from its full potential what does tomorrow hold for energy consumption and its

various renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with

Energy and Fossil Fuels January 30‚ 2012 I will be covering different types of energy and how they are converted into other forms of energy. I will also discuss what fossil fuels are‚ alternatives to fossil fuels and the advantages and disadvantages of alternatives. There are several different forms of energy and how it can be converted from one type to another. According to The Law of Conservation of Energy; energy can neither be created or destroyed‚ only transferred

Article Diesel Fuel Injection One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor. A port injection system injects fuel just prior to the intake stroke (outside the cylinder). A carburetor mixes air and fuel long before the air enters the cylinder. In a car engine‚ therefore‚ all of the fuel is loaded into the cylinder during the intake stroke and then compressed. The compression of the fuel/air mixture limits

Fuel is one of the important resources in our society. We use the fuels to support our living‚ produce electricity‚ heat homes‚ and operate machinery. Since the fuel is a limited resource‚ the fuel scarcity will be a big issue in the future. The price of the gasoline is currently on the rise. NASCAR cut the volume of fuel cell from twenty gallons to thirteen gallons each car. There is a high demand for a new energy. After the issue of fuel crisis was brought up‚ the society started to be interested

FUEL CELL CARS Fuel Cell cars are a major part of the fleet of Zero-Emission Vehicles. The fuel cells are fueled with pure hydrogen and hence they are considered to be zero emission vehicles. Fuel cells have been used on spacecraft for many years to power electric equipment. These are fueled with liquid hydrogen from the spacecraft ’s rocket fuel tanks. Basic Mechanics Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. The electricity then powers an electric motor‚ just like

In recent decades‚ we have seen a remarkable advancement in science and technology. Owing to this‚ many wonder why the primary sources of consumer energy remain non-renewable fuels; petroleum (36%)‚ coal (27%) and gas (23%) [International Energy Agency‚ 2013]. The issue with this is‚ “fossil fuels” which took millions of years to form are running out at an unprecedented rate‚ and there is no consensual view as to what will replace them. There are many reasons why the general population should be

Biodiesel is an efficient alternative fuel‚ for the reason that biodiesel is a safe‚ eco-friendly‚ and affordable option. Biodiesel is a clean burning alternative fuel. It is renewable and generated from a variety of vegetable oils and animal fats‚ not raw vegetable oil. Raw vegetable oil cannot be utilized because it has not undergone the process of

September 17‚ 2013 The purpose of this paper is to assess personal energy use and speak about the forms of energy that I currently rely on and the sources they originate from. It also talks about renewable energy sources that would be most and least appropriate to use in a certain location. Then it refers to the advantages and disadvantages of the energy source that I currently use‚ also about renewable ones that have been identified. The last part of the paper addresses energy conservation
